Economics-Watching: How Green Innovation Can Stimulate Economies and Curb Emissions

[from IMF Blog, by Zeina Hasna, Florence Jaumotte & Samuel Pienknagura]

Coordinated climate policies can spur innovation in low-carbon technologies and help them spread to emerging markets and developing economies

Making low-carbon technologies cheaper and more widely available is crucial to reducing harmful emissions.

We have seen decades of progress in green innovation for mitigation and adaptation: from electric cars and clean hydrogen to renewable energy and battery storage.

More recently though, momentum in green innovation has slowed. And promising technologies aren’t spreading fast enough to lower-income countries, where they can be especially helpful to curbing emissions. Green innovation peaked at 10 percent of total patent filings in 2010 and has experienced a mild decline since. The slowdown reflects various factors, including hydraulic fracking that has lowered the price of oil and technological maturity in some initial technologies such as renewables, which slows the pace of innovation.

The slower momentum is concerning because, as we show in a new staff discussion note, green innovation is not only good for containing climate change, but for stimulating economic growth too. As the world confronts one of the weakest five-year growth outlooks in more than three decades, those dual benefits are particularly appealing. They ease concerns about the costs of pursuing more ambitious climate plans. And when countries act jointly on climate, we can speed up low-carbon innovation and its transfer to emerging markets and developing economies.

IMF research [archived PDF] shows that doubling green patent filings can boost gross domestic product by 1.7 percent after five years compared with a baseline scenario. And that’s under our most conservative estimate—other estimates show up to four times the effect.

The economic benefits of green innovation mostly flow through increased investment in the first few years. Over time, further growth benefits come from cheaper energy and production processes that are more energy efficient. Most importantly, they come from less global warming and less frequent (and less costly) climate disasters.

Green innovation is associated with more innovation overall, not just a substitution of green technologies for other kinds. This may be because green technologies often require complementary innovation. More innovation usually means more economic growth.

A key question is how countries can better foster green innovation and its deployment. We highlight how domestic and global climate policies spur green innovation. For example, a big increase in the number of climate policies tends to boost green patent filings, our preferred proxy for green innovation, by 10 percent within five years.

Some of the most effective policies to stimulate green innovation include emissions-trading schemes that cap emissions, feed-in-tariffs, which guarantee a minimum price for renewable energy producers, and government spending, such as subsidies for research and development. What’s more, global climate policies result in much larger increases in green innovation than domestic initiatives alone. International pacts like the Kyoto Protocol and the Paris Agreement amplify the impact of domestic policies on green innovation.

One reason policy synchronization has a prominent impact on domestic green innovation is what is called the market size effect. There’s more incentive to develop low-carbon technologies if innovators can expect to sell into a much larger potential market, that is, in countries which adopted similar climate policies.

Another is that climate policies in other countries generate green innovations and knowledge that can be used in the domestic economy. This is known as technology diffusion. Finally, synchronized policy action and international climate commitments create more certainty around domestic climate policies, as they boost people’s confidence in governments’ commitment to addressing climate change.

Climate policies even help spread the use of low-carbon technologies in countries that are not sources of innovation, through trade and foreign-direct investment. Countries that introduce climate policies see more imports of low-carbon technologies and higher green FDI inflows, especially in emerging markets and developing economies.

Risks of protectionism

Lowering tariffs on low-carbon technologies can further enhance trade and FDI in green technologies. This is especially important for middle- and low-income countries where such tariffs remain high. On the flipside, more protectionist measures would impede the broader spread of low-carbon technologies.

In addition, and given evidence of economies of scale, protectionism—with ultimately smaller potential markets—could stifle incentives for green innovation and lead to duplication of efforts across countries.

The risks of protectionism are exacerbated when climate policies, such as subsidies, do not abide by international rules. For example, local content requirements, whereby only locally produced green goods benefit from subsidies, undermine trust in multilateral trade rules and could result in retaliatory measures.

Beyond embracing a rules-based approach to climate policies, the advanced economies, where most green innovation occurs, have an important responsibility: sharing the technology so that emerging and developing economies can get there faster. Such direct technology transfers hold the promise of a double dividend for emerging markets and developing economies—reducing emissions and yielding economic benefits.

Economics-Watching: “Doing Nothing” Is Still Doing a Lot

[from the Federal Reserve Bank of Philadelphia, speech by Patrick T. Harker President and Chief Executive Officer at the National Association of Corporate Directors Webinar, Philadelphia, PA (Virtual)]

Good afternoon, everyone.

I appreciate that you’re all giving up part of the end of your workday for us to be together, if only virtually.

My thanks to my good friend, Rick Mroz, for that welcome and introduction.

I do believe we’re going to have a productive session. But just so you all know, as much as I enjoy speaking and providing my outlook, I enjoy a good conversation even more.

So, first, let’s take a few minutes so I can give you my perspective on where we are headed, and then I will be more than happy to take questions and hear what’s on your minds.

But before we get into any of that, I must begin with the standard Fed disclaimer: The views I express today are my own and do not necessarily reflect those of anyone else on the Federal Open Market Committee (FOMC) or in the Federal Reserve System.

Put simply, this is one of those times where the operative words are, “Pat said,” not “the Fed said.”

Now, to begin, I’m going to first address the two topics that I get asked about most often: interest rates and inflation. And I would guess they are the topics front and center in many of your minds as well.

After the FOMC’s last policy rate hike in July, I went on record with my view that, if economic and financial conditions evolved roughly as I expected they would, we could hold rates where they are. And I am pleased that, so far, economic and financial conditions are evolving as I expected, if not perhaps even a tad better.

Let’s look at the current dynamics. There is a steady, if slow, disinflation under way. Labor markets are coming into better balance. And, all the while, economic activity has remained resilient.

Given this, I remain today where I found myself after July’s meeting: Absent a stark turnabout in the data and in what I hear from contacts, I believe that we are at the point where we can hold rates where they are.

In barely more than a year, we increased the policy rate by more than 5 percentage points and to its highest level in more than two decades — 11 rate hikes in a span of 12 meetings prior to September. We not only did a lot, but we did it very fast.

We also turned around our balance sheet policy — and we will continue to tighten financial conditions by shrinking the balance sheet.

The workings of the economy cannot be rushed, and it will take some time for the full impact of the higher rates to be felt. In fact, I have heard a plea from countless contacts, asking to give them some time to absorb the work we have already done.

I agree with them. I am sure policy rates are restrictive, and, as long they remain so, we will steadily press down on inflation and bring markets into a better balance.

Holding rates steady will let monetary policy do its work. By doing nothing, we are still doing something. And I would argue we are doing quite a lot.

Headline PCE inflation remained elevated in August at 3.5 percent year over year, but it is down 3 percentage points from this time last year. About half of that drop is due to the volatile components of energy and food that, while basic necessities, they are typically excluded by economists in the so-called core inflation rate to give a more accurate assessment of the pace of disinflation and its likely path forward.

Well, core PCE inflation has also shown clear signs of progress, and the August monthly reading was its smallest month-over-month increase since 2020.

So, yes, a steady disinflation is under way, and I expect it to continue. My projection is that inflation will drop below 3 percent in 2024 and level out at our 2 percent target thereafter.

However, there can be challenges in assessing the trends in disinflation. For example, September’s CPI report came out modestly on the upside, driven by energy and housing.

Let me be clear about two things. First, we will not tolerate a reacceleration in prices. But second, I do not want to overreact to the normal month-to-month variability of prices. And for all the fancy techniques, the best way to separate a signal from noise remains to average data over several months. Of course, to do so, you need several months of data to start with, which, in turn, demands that, yes, we remain data-dependent but patient and cautious with the data.

Turning to the jobs picture, I do anticipate national unemployment to end the year at about 4 percent — just slightly above where we are now — and to increase slowly over the next year to peak at around 4.5 percent before heading back toward 4 percent in 2025. That is a rate in line with what economists call the natural rate of unemployment, or the theoretical level in which labor market conditions support stable inflation at 2 percent.

Now, that said, as you know, there are many factors that play into the calculation of the unemployment rate. For instance, we’ve seen recent months where, even as the economy added more jobs, the unemployment rate increased because more workers moved off the sidelines and back into the labor force. There are many other dynamics at play, too, such as technological changes or public policy issues, like child care or immigration, which directly impact employment.

And beyond the hard data, I also have to balance the soft data. For example, in my discussions with employers throughout the Third District, I hear that given how hard they’ve worked to find the workers they currently have, they are doing all they can to hold onto them.

So, to sum up the labor picture, let me say, simply, I do not expect mass layoffs.

do expect GDP gains to continue through the end of 2023, before pulling back slightly in 2024. But even as I foresee the rate of GDP growth moderating, I do not see it contracting. And, again, to put it simply, I do not anticipate a recession.

Look, this economy has been nothing if not unpredictable. It has proven itself unwilling to stick to traditional modeling and seems determined to not only bend some rules in one place, but to make up its own in another. However, as frustratingly unpredictable as it has been, it continues to move along.

And this has led me to the following thought: What has fundamentally changed in the economy from, say, 2018 or 2019? In 2018, inflation averaged 2 percent almost to the decimal point and was actually below target in 2019. Unemployment averaged below 4 percent for both years and was as low as 3.5 percent — both nationwide and in our respective states — while policy rates peaked below 2.5 percent.

Now, I’m not saying we’re going to be able to exactly replicate the prepandemic economy, but it is hard to find fundamental differences. Surely, I cannot and will not minimize the immense impacts of the pandemic on our lives and our families, nor the fact that for so many, the new normal still does not feel normal. From the cold lens of economics, I do not see underlying fundamental changes. I could also be wrong, and, trust me, that would not be the first time this economy has made me rethink some of the classic models. We just won’t know for sure until we have more data to look at over time.

And then, of course, there are the economic uncertainties — both national and global — against which we also must contend. The ongoing auto worker strike, among other labor actions. The restart of student loan payments. The potential of a government shutdown. Fast-changing events in response to the tragic attacks against Israel. Russia’s ongoing war against Ukraine. Each and every one deserves a close watch.

These are the broad economic signals we are picking up at the Philadelphia Fed, but I would note that the regional ones we follow are also pointing us forward.

First, while in the Philadelphia Fed’s most recent business outlook surveys, which survey manufacturing and nonmanufacturing firms in the Third District, month-over-month activity declined, the six-month outlooks for each remain optimistic for growth.

And we also publish a monthly summary metric of economic activity, the State Coincident Indexes. In New Jersey, the index is up slightly year over year through August, which shows generally positive conditions. However, the three-month number from June through August was down, and while both payroll employment and average hours worked in manufacturing increased during that time, so did the unemployment rate — though a good part of that increase can be explained as more residents moved back into the labor force.

And for those of you joining us from the western side of the Delaware River, Pennsylvania’s coincident index is up more than 4 percent year over year through August and 1.7 percent since June. Payroll employment was up, and the unemployment rate was down; however, the number of average hours worked in manufacturing decreased.

There are also promising signs in both states in terms of business formation. The number of applications, specifically, for high-propensity businesses — those expected to turn into firms with payroll — are remaining elevated compared with pre-pandemic levels. Again, a promising sign.

So, it is against this full backdrop that I have concluded that now is the time at which the policy rate can remain steady. But I can hear you ask: “How long will rates need to stay high.” Well, I simply cannot say at this moment. My forecasts are based on what we know as of late 2023. As time goes by, as adjustments are completed, and as we have more data and insights on the underlying trends, I may need to adjust my forecasts, and with them my time frames.

I can tell you three things about my views on future policy. First, I expect rates will need to stay high for a while.

Second, the data and what I hear from contacts and outreach will signal to me when the time comes to adjust policy either way. I really do not expect it, but if inflation were to rebound, I know I would not hesitate to support further rate increases as our objective to return inflation to target is, simply, not negotiable.

Third, I believe that a resolute, but patient, monetary policy stance will allow us to achieve the soft landing that we all wish for our economy.

Before I conclude and turn things over to Rick to kick off our Q&A, I do want to spend a moment on a topic that he and I recently discussed, and it’s something about which I know there is generally great interest: fintech. In fact, I understand there is discussion about NACD hosting a conference on fintech.

Well, last month, we at the Philadelphia Fed hosted our Seventh Annual Fintech Conference, which brought business and thought leaders together at the Bank for two days of real in-depth discussions. And I am extraordinarily proud of the fact that the Philadelphia Fed’s conference has emerged as one of the premier conferences on fintech, anywhere. Not that it’s a competition.

I had the pleasure of opening this year’s conference, which always puts a focus on shifts in the fintech landscape. Much of this year’s conference centered around developments in digital currencies and crypto — and, believe me, some of the discussions were a little, shall we say, “spirited.” However, my overarching point to attendees was the following: Regardless of one’s views, whether in favor of or against such currencies, our reality requires us to move from thinking in terms of “what if” to thinking about “what next.”

In many ways, we’re beyond the stage of thinking about crypto and digital currency and into the stage of having them as reality — just as AI has moved from being the stuff of science fiction to the stuff of everyday life. What is needed now is critical thinking about what is next. And we at the Federal Reserve, both here in Philadelphia and System-wide, are focused on being part of this discussion.

We are also focused on providing not just thought leadership but actionable leadership. For example, the Fed rolled out our new FedNow instant payment service platform in July. With FedNow, we will have a more nimble and responsive banking system.

To be sure, FedNow is not the first instant payment system — other systems, whether operated by individual banks or through third parties, have been operational for some time. But by allowing banks to interact with each other quickly and efficiently to ensure one customer’s payment becomes another’s deposit, we are fulfilling our role in providing a fair and equitable payment system.

Another area where the Fed is assuming a mantle of leadership is in quantum computing, or QC, which has the potential to revolutionize security and problem-solving methodologies throughout the banking and financial services industry. But that upside also comes with a real downside risk, should other not-so-friendly actors co-opt QC for their own purposes.

Right now, individual institutions and other central banks globally are expanding their own research in QC. But just as these institutions look to the Fed for economic leadership, so, too, are they looking to us for technological leadership. So, I am especially proud that this System-wide effort is being led from right here at the Philadelphia Fed.

I could go on and talk about fintech for much longer. After all, I’m actually an engineer more than I am an economist. But I know that Rick is interested in starting our conversation, and I am sure that many of you are ready to participate.

But one last thought on fintech — my answers today aren’t going to be generated by ChatGPT.

On that note, Rick, thanks for allowing me the time to set up our discussion, and let’s start with the Q&A.

Economy-Watching, USA: Global Supply Chain Pressure Index: April 2023 Update

[from the Federal Reserve Bank of New York]

A new reading of the Global Supply Chain Pressure Index has been posted.

Estimates for March 2023

  • Global supply chain pressures decreased again in March, falling from 0.28 to 1.06 standard deviations below the index’s historical average.
  • There were significant downward contributions by many of the factors, with the largest negative contributions from European Area delivery times, European Area backlogs, and Taiwanese purchases.
  • The GSCPI’s recent movements suggest that global supply chain conditions have largely normalized after experiencing temporary setbacks around the turn of the year.

The GSCPI compiles more than two dozen metrics across seven economies—data on global transportation costs and regional manufacturing conditions—to track shifts in supply chain pressures from 1997 to the present.

The GSCPI is updated regularly at 10 AM ET on the fourth business day of each month.

The GSCPI is a product of the Federal Reserve Bank of New York’s Applied Macroeconomics and Econometrics Center.

Facing the Global South: Building a New International System by Yang Ping

“If you raise [the development of the BRI] to the strategic level, there are countries where … you will have to lose money and there are countries where you will be free to make money.”

by Thomas des Garets Geddes, Sinification

Dear Everyone,

How to respond to the growing political divide between China and the West marked by partial decoupling, security alliances, and the risk of sanctions, amongst other things, continues to be a major topic of discussion among China’s intellectual elite. As already evidenced in previous editions of this newsletter, opinions vary considerably. Those presented here so far have ranged from Da Wei (达巍) stressing the importance of preserving if not strengthening ties with the West and Shen Wei (沈伟) arguing in favor of reforming the WTO and building up a network of free trade agreements to Ye Hailin (叶海林) emphasizing the need for China to demonstrate its military might to demobilize U.S. allies and Lu Feng (路风) calling for self-reliance and greater assertiveness in the field of tech. A certain amount of overlap certainly exists among these perspectives but the differences are nonetheless striking.

Today’s edition of Sinification looks at a speech made last month by Yang Ping (杨平), head and editor-in-chief of the highly regarded Beijing Cultural Review (文化纵横, hereafter BCR). Yang is also director of the Longway Foundation (修远基金会) which publishes BCR. The foundation describes its publication as “the most influential magazine of intellectual thought and commentary in China” and sees itself as having a key role in helping shape the direction of intellectual debates in China (“议题的设置就是意识形态斗争成功的一半”). Indeed, BCR often republishes old articles at key junctures as so often highlighted by David Ownby’s wonderful Reading the China Dream.

The following are excerpts from an edited transcript of a speech by Yang made at an event hosted by Renmin University’s Chongyang Institute for Financial Studies, which was attended by China’s Vice-minister of foreign affairs Xie Feng (谢锋). In his speech, Yang advocates building a new international system led by countries in the Global South (which, of course, includes China) rather than the West. His ideas are not particularly novel but are nevertheless noteworthy in that they represent yet another viewpoint in the ongoing debate over how China should respond to the increasing tensions that characterize its relations with the U.S. and other Western countries. Next week, I will be sharing a somewhat longer piece that proposes a way of protecting China from the growing threat of Western sanctions.

Yang’s speech in a nutshell:

  • Capitalist politics” are no longer in line with “capitalist economics.” The former now undermines globalization, while the latter supports it.
  • Sanctions, export controls, friend-shoring and alliance-building are damaging the world economy and further alienating China from the current U.S.-led international order.
  • China must respond to this growing trend by building a “new type of international system” with other countries in the Global South.
  • BRI projects should be increasingly focused on achieving this goal and thus allow more room for loss-making endeavors.

Capitalist politics ≠ Capitalist economics

“Since 2022 and the Russo-Ukrainian conflict, our main focus and topic of discussion has been China’s construction of a new type of international system.

“The most important feature of today’s world is the beginning of a separation between capitalist politics and capitalist economics. The capitalist political order and the capitalist economic order do not support each other [any longer].

“We have witnessed two typical manifestations of the separation of politics and the economy and the impact of politics on the economy:

  1. The first is the conflict between Russia and Ukraine. The sanctions imposed on Russia by the United States and the West have reached unthinkable, abominable [令人发指] and unimaginable proportions. Under established international rules, it was understood that such sanctions could not possibly occur, but now they have. These include the fracturing of the financial system, the expropriation and seizure of Russian private assets and the freezing of Russian foreign exchange reserves. These are all abominable and unimaginable forms of confrontation. At the same time, the Russo-Ukrainian conflict has led to serious disruptions in global food and energy systems and supply chains, with massive food ‘shortages’ and soaring food prices, particularly in developing countries. Sanctions and political repression [政治打压] have severely disrupted the [world’s] economic order.
  2. The second is the conflict between the U.S. and China. Since the Trump era, the U.S. has been engaged in a trade war against China, mainly by raising tariffs. Basically, this was simply about balancing trade [with China] and used mainly economic means. But under Biden, it [has become] a war that mixes politics with economics. Biden’s strategy towards China can basically be summed up in just a few words: one, friend-shoring, [i.e.] only allowing friendly countries into [parts of] its supply chains; two, alliance politics, [i.e.] continuously forging an alliance system involving NATO, the European Union, Japan, AUKUS and the four Asia-Pacific countries [I assume he is referring to South Korea, Japan, New Zealand and Australia taking part for the first time in a NATO summit last year] and constantly opposing China [不断应对中国]; three, its so-called ‘precision strikes’, [i.e.] its radical crackdown on China’s high tech [industry], especially our chip industry.”

China is being pushed out of the U.S.-led international system

“The information I have seen so far is that the number of Chinese companies included in the U.S.’s ‘entity list’ has risen from 132 under Trump to over 530 now. The scope of such point-to-point [点对点] precision strikes is constantly expanding. With such a political impact on the economy, we can feel the [world’s] economic order being disrupted across the board. The world is moving inexorably in the direction of decoupling. The phenomenon of politics affecting the economy and the capitalist political order no longer upholding the capitalist economic order are extremely striking.

“In such a context, the challenges now facing China are extremely serious and varied. We have the pressures of dealing both with containment in the Indo-Pacific and with the U.S.-led politics of alliances across the world. More importantly and fundamentally China faces the strategic task of building a new type of international system [新型国际体系] … The existing Western-dominated international system used to be one in which we tried hard to blend [so as] to become one with it. During this process, we [sought to] absorb the West’s advanced technologies and management [practices] and thus complete our mission of industrialisation and modernization.

“But once you enter the existing international system, he [who is already inside] does not want to play with you, and even wants to drive you back out. He wants to divide both supply chains and the economic system into two parts [搞成两套] and desperately wants to contain and suppress you. This is not something that can be determined by your own subjective preferences. He has made up his mind: you have already become his ‘fated opponent’ [命定的对手]. He has to suppress you and drive you out of the existing system.”

Building a new international system with the Global South

“It is at this point that China is faced with the task of constructing a new type of international system that is not dominated by the West. In today’s so-called strategic quadrangle consisting of the U.S., Europe, Russia and China, how to construct such an international system appears particularly difficult [逼庂 literally means ‘narrow’ or ‘cramped’ rather than ‘difficult’].

“But if we look a little further south, we will find a vast number of developing countries, the Third World and the countries of the global South. They should be our strategy’s depth [我们的战略纵深]. That is to say, [we should] build a new type of international relations and a new type of international system that has strategic depth and in which China and the countries of the global South are jointly integrated. [This] is, in my view, an important strategic task for China’s international relations in the coming decades.”

BRI projects: Strategy trumps profitability

“For China today, especially for businesses and governments at all levels [within China] that are currently working hard to develop BRI trade, there is a very important point to which they should be alerted or reminded about: the development of the BRI has to go beyond mere business, beyond the general export of [China’s excess] production capacity, beyond the partial thinking of industry and the partial thinking at the regional level, or the simple economic way of thinking of business. The development of the BRI should be considered at the strategic level. That is, it should be included into China’s strategy when thinking about Africa, South America, Southeast Asia and Central Asia.

“If you raise [the development of the BRI] to the strategic level, there are countries where you won’t be able to make money and will have to lose money, and there are countries where you will be free to make money. You have to unite the two within your organic strategy.

“The strategic task of building a new type of international system is, in my view, a strategic proposition that Chinese think tanks and research institutes should pay very close attention to with regards to international relations.

“Time is limited today. I just wanted to make a start here. I hope to receive your corrections and criticisms. Thank you!”

Economics-Watching: FRBSF Economic Letter

[from the Federal Reserve Bank of San Francisco]

Are Inflation Expectations Well Anchored in Mexico?

by Remy Beauregard, Jens H.E. Christensen, Eric Fischer and Simon Zhu

Price inflation has increased sharply since early 2021 in many countries, including Mexico. If sustained, high inflation in Mexico could raise questions about the ability of its central bank to bring inflation down to its 3% inflation target. However, analyzing the difference between market prices of nominal and inflation-indexed government bonds suggests investors’ long-term inflation expectations in Mexico are close to the central bank’s inflation target and are projected to remain so in coming years.


Inflation has risen substantially in many countries, including Mexico, since early 2021, driven in part by unique factors related to the COVID-19 pandemic. Sustained elevated inflation could be particularly challenging for inflation-targeting central banks in emerging economies given their higher macroeconomic uncertainty and greater sensitivity to external shocks compared with more developed economies. To examine this risk for a representative emerging economy affected by COVID-era disruptions in much the same way as the United States, we focus on Mexico, which has conducted monetary policy since 2002 according to an inflation targeting regime with a target rate for consumer price inflation of 3% per year.

In this Economic Letter, we assess whether recent higher inflation is leading businesses and households in Mexico to expect inflation to remain high over the long run. Specifically, we focus on what rising market-based measures of inflation compensation may imply about bond investors’ outlook for inflation. The rise in inflation compensation since spring 2021 could reflect three factors: an increase in investorsinflation expectations, an uptick in the premium investors demand for assuming inflation risk, or changes in other risk and liquidity premiums. We explore the relative importance of each of these factors using a novel dynamic term structure model of nominal and inflation-adjusted yields described in Beauregard et al. (2021, henceforth BCFZ). Overall, our results for five-year inflation expectations five years from now suggest Mexican bond investors’ long-term inflation expectations have been little affected by the recent rise in inflation. Instead, the rise in inflation compensation reflects a notable uptick in the inflation risk premium to the high end of its historical range. This suggests that, despite inflation expectations being little changed on average, some investors are particularly concerned about the risk that inflation will remain above expected levels.

The recent rise in Mexican inflation

Figure 1 shows the year-over-year change in the Mexican consumer price index (CPI) measured both by the headline CPI (green line) and the more stable core CPI (blue line) that strips out volatile food and energy prices. Also shown with a horizontal gray line is the 3% inflation target of the nation’s central bank, the Bank of Mexico.

Figure 1: Mexican consumer price index inflation

We note that Mexican CPI inflation has averaged somewhat above the Bank of Mexico’s target since its adoption in 2002. More importantly, CPI inflation in Mexico appears to have become more volatile and somewhat higher over the past five years. Although previous research by De Pooter et al. (2014) found inflation expectations in Mexico to be well anchored, the significant global economic dislocations caused by the coronavirus pandemic and related inflationary pressures could impact inflation expectations of businesses and households.

To assess the persistence of the recent rise in Mexican inflation, we turn to financial market data, which reflect forward-looking expectations among a large and diverse group of investors and financial market participants. Specifically, we consider prices of conventional fixed-coupon bonds that pay a nominal interest rate and inflation-indexed bonds that pay a real interest rate because their cash flows are adjusted with the change in the CPI and therefore maintain their purchasing power. Both types of securities are issued and guaranteed by the Mexican government.

The difference between nominal and real yields for bonds of the same maturity is known as breakeven inflation (BEI). This represents a market-based measure of inflation compensation used to assess financial market participants’ inflation expectations. Figure 2 shows BEI rates at different maturities, meaning annual average rates of inflation compensation between now and maturity, from 1 to 10 years at the end of March 2021 (green line) and at the end of November 2022 (blue line). The slightly upward-sloping BEI curve of close to 3% in 2021 contrasts with the higher downward-sloping BEI curve in 2022.

Figure 2: BEI curves for 1-year to 10-year Mexican bond maturities
BEI curves for 1-year to 10-year Mexican bond maturities
Source: Authors’ calculations using bond prices from Bloomberg.

The increase for shorter maturities, the left end of the 2022 BEI curve, is closely tied to the current high level of inflation and suggests inflation may remain elevated for some time. In contrast, the increase at longer maturities, the right end of the 2022 BEI curve, suggests that investors’ longer-term inflation expectations may be drifting above the Bank of Mexico’s inflation target. To better understand the shape and sources of variation of the BEI curve we use a yield curve model.

A yield curve model of nominal and real yields

Market-based measures of inflation compensation such as BEI rates contain three components. First, they include the average CPI inflation rate expected by bond investors, which is the focus here. Second is an inflation risk premium to compensate investors for the uncertainty of future inflation. This premium is embedded in nominal yields that provide no inflation protection. Third is the difference in relative market liquidity between standard fixed-coupon and inflation-indexed bonds. As discussed in BCFZ, both of these types of Mexican bonds are less liquid than U.S. Treasuries, and their prices therefore contain a discount to compensate investors for their liquidity risk. Neither the inflation risk premium nor the liquidity premiums are directly observable and must therefore be estimated.

To adjust for these challenges, we first use the nominal and real yields model developed in BCFZ to identify liquidity premiums in standard fixed-coupon and inflation-indexed bond prices as a function of the time since issuance and the remaining time to maturity. The time since issuance serves as a proxy for declining liquidity as, over time, a larger fraction of bonds gets locked into buy-and-hold strategies. We refer to the observed BEI net of estimated liquidity premiums as the adjusted BEI. In a second step, we then separate adjusted BEI into components representing investorsinflation expectations using a formula based on the absence of bond market arbitrage opportunities and the residual inflation risk premium.

Results

To assess whether investorsinflation outlook has fundamentally changed, we follow De Pooter et al. (2014) and examine the five-year forward BEI rate that starts five years ahead, denoted 5yr5yr BEI. This is a horizon sufficiently long into the future that most transitory shocks to the economy can be expected to have vanished. Hence, the embedded inflation expectations are presumably less affected by current high inflation and pandemic-related transitory conditions and can therefore speak to the question about the anchoring of inflation expectations in Mexico.

Figure 3 shows the breakdown of 5yr5yr BEI into its various components according to our model. The dark blue line is the observed BEI, and the red line is the estimated adjusted BEI without liquidity risk premiums or other residual disturbances. The difference between these two measures of BEI—the yellow shaded area—represents the model’s estimate of the net liquidity premium or distortion of the observed BEI series due to risk premiums in both nominal and inflation-indexed bond prices. The adjusted BEI is entirely above the observed BEI, suggesting the liquidity risk distortions are systematically larger in the inflation-indexed bond prices, consistent with similar evidence from the U.S. Treasury market (Andreasen and Christensen 2016). Note that the net BEI liquidity premium widened around the financial turmoil in spring 2020 at the start of the pandemic and remains elevated.

The model also allows us to break down the adjusted BEI into an expected inflation component (light blue line) and the residual inflation risk premium (green line). Also shown is the Bank of Mexico’s 3% inflation target (gray horizontal line). For comparison, the figure also shows the 5yr5yr expected CPI inflation in Mexico reported semiannually in the Consensus Forecasts surveys (dark blue squares). We note that both observed and adjusted BEI have trended higher since the start of the pandemic in early 2020. Importantly, the breakdown indicates that long-term expected inflation in Mexico has remained stable, slightly above the 3% inflation target. As a result, the increase in BEI can be attributed to the inflation risk premium, which is at the high end of its historical range towards the end of our sample. Given the elevated levels of current inflation, this suggests some investors are concerned that inflation could remain elevated for longer than currently anticipated.

This raises the question of whether long-term inflation expectations in Mexico are likely to remain anchored near their current level going forward. To assess this risk, we simulate 10,000-factor paths over a three-year horizon using the estimated factors and factor dynamics as of November 2022—that is, the simulations are conditioned on the shapes of the nominal and real yield curves and investors’ embedded forward-looking expectations as of November 2022. These simulated factor paths are then converted into forecasts of 5yr5yr expected inflation. Figure 4 shows the median projection (solid green line) and the 5th and 95th percentile values (dashed green lines) for the simulated 5yr5yr expected inflation over a three-year horizon.

Our model projections indicate that long-term inflation expectations are likely to deviate only modestly from their current level, consistent with the variation of the historical estimates back to 2009. Overall, our findings represent tangible evidence that long-term inflation expectations remain well-anchored in Mexico despite the recent rise in inflation.

Conclusion

Global inflation pressures in the aftermath of the pandemic have raised fears about a sustained increase in the level of inflation around the world, which could be particularly challenging for developing economies with monetary policy guided by an inflation target. In this Letter, to assess this risk for a major emerging economy with an established inflation target, we examine the variation in Mexico’s nominal and inflation-indexed bond prices, while accounting for their respective liquidity risk premiums. This allows us to estimate Mexican bond investors’ inflation expectations and associated risk premiums. The results reveal that the inflation risk premium has pushed up Mexican BEI rates in recent years, while investors’ long-term inflation expectations have remained stable near the Bank of Mexico’s inflation target despite the rise in inflation.

The policy path needed to keep inflation expectations anchored in a situation with highly elevated inflation may involve tradeoffs. The Bank of Mexico responded early and forcefully to inflation pressures starting in June 2021 and has indicated further tightening of the policy rate would likely be appropriate to bring inflation back down to target over the medium term. This could lower economic growth in Mexico in both 2022 and 2023. On the other hand, history shows that it may be difficult and costly to reverse extended departures from announced inflation targets. Thus, it will be important for central banks with inflation-targeting frameworks to monitor measures of long-term inflation expectations in the current situation.

Economics-Watching: FedViews for January 2023

[from the Federal Reserve Bank of San Francisco]

Adam Shapiro, vice president at the Federal Reserve Bank of San Francisco, stated his views on the current economy and the outlook as of January 12, 2023.

  • While continuing to cool over the last several months, 12-month inflation remains at historically high levels. The headline personal consumption expenditures (PCE) price index rose 5.5% in November 2022 from a year earlier. This marks a decline in inflation to a level last observed in October 2021, but still well above the Fed’s longer-run goal of 2%. A portion of the inflation moderation is attributable to recent declines in energy prices. Core PCE inflation, which removes food and energy prices, has shown less easing.
  • Owing to fiscal relief efforts and lower household spending over the course of the pandemic, consumers accumulated over $2 trillion dollars in excess savings, based on pre-pandemic trends. Since then, consumers have drawn down over half of this excess savings which has helped support recent growth in personal consumption expenditures. A considerable amount of accumulated savings remains for some consumers to support spending in 2023.
  • In the wake of the pandemic, consumer spending patterns shifted away from services towards goods. While there appears to be some normalization of spending behavior, this shift has generally persisted. Real goods spending remains significantly above its pre-pandemic trend, driven by strong demand for durables such as furniture, electronics, and recreational goods. Spending on services has shown a resurgence but remains below its pre-pandemic trend.
  • Supply chain bottlenecks for materials and labor remain a constraint on production, although there are some recent signs of easing. The fraction of manufacturers who reported operating below capacity due to insufficient materials peaked in late 2021 and has moderately declined over the past year. However, the fraction of manufacturers reporting insufficient labor has persisted at high levels.
  • The labor market remains tight, despite some signs of cooling. The number of available jobs remains well above the number of available workers, although vacancy postings have been trending down in recent months. The tight labor market has put continued upward pressure on wages and labor market turnover.
  • A decomposition of headline PCE inflation into supply– and demand-driven components shows that both supply and demand factors are responsible for the recent rise in inflation. The surge in inflation in early 2021 was mainly due to an increase in demand-driven factors. Subsequently, supply factors became more prevalent for the remainder of 2021. Supply-driven inflation has moderated significantly over recent months, while demand-driven inflation remains elevated.
  • The Federal Open Market Committee (FOMC) raised the federal funds rate by 50 basis points at the December meeting to a range of 4.25 to 4.5%. This cycle of continued rate increases since March of last year represents the fastest pace of monetary policy tightening in 40 years. The increase in the federal funds rate has been accompanied by a gradual reduction in the size of the Federal Reserve’s balance sheet.
  • Economic activity in sectors such as housing, which is sensitive to rising interest rates, has slowed considerably in recent months. Housing starts have fallen steadily over the past year, as have other housing market indicators, such as existing home sales and house prices.
  • Although the labor market is currently very strong, financial markets are pointing to some downside risks. Namely, the difference between longer- and shorter-term interest rates has turned negative, which historically tends to occur immediately preceding recessions. It remains unclear whether lower longer-term yields are indicative of anticipated slower growth or lower inflation.
  • Short-term inflation expectations remain elevated relative to their pre-pandemic levels in December 2019. Consumers are expecting prices to rise 5% this year, while professional forecasters are expecting prices to rise 3.5%. Longer-term inflation expectations remain more subdued, indicating that both consumers and professionals believe inflation pressures will eventually dissipate.
  • Rent inflation is expected to remain high over the next year. The prices for asking rents have grown quite substantially over the last two years. As new leases begin and existing leases are renewed, these higher asking rents will flow into the stock of rental units, putting upward pressure on rent inflation.
  • We are expecting inflation to moderate over the next few years as monetary policy continues to restrain demand and supply bottlenecks continue to ease. We anticipate that it will take some time for inflation to reach the Fed’s longer-run goal of 2%.
Inflation is cooling, but remains very high
Savings are boosting consumer demand
Goods consumption remains elevated
Supply shortages are prevalent, but easing
Labor market remains tight, but is cooling
Both supply and demand drive inflation
Monetary policy tightening is having real effects
Yield curve is inverted, signaling recession risk
Short-term inflation expectations remain elevated
High rent inflation is in the pipeline
Inflation likely to remain above 2% for some time

Globalization and Its Nuances

The PBS TV program History Detectives had an episode entitled “Atocha Spanish Silver” where the wreck of the Spanish ship Atocha was described like this:

“In 1985, one of the greatest treasure discoveries was made off the Florida Keys, when the wreck of the Spanish ship Atocha was found. On board were some forty tons of silver and gold, which in 1622 had been heading from the New World to the Spanish treasury as the means to fund the Thirty Years’ War.”

Is this an obvious case of globalization? What about Marco Polo? RomeHan dynasty China trade in silks? Silk Road and Samarkand? Colombus? Magellan? Vasco da Gama?

All of these cases constitute a kind of harmless kind of “pop globalization” based on exotic voyages and travels.

Consider another such example, perhaps more academic:

“About the middle of the sixteenth century Antwerp reached its apogee. For the first time in history there existed both a European and a world market; the economies of different parts of Europe had become interdependent and were linked through the Antwerp market, not only with each other but also with the economies of large parts of the rest of the world. Perhaps no other city has ever again played such a dominant role as did Antwerp in the second quarter of the sixteenth century.”

(Europe in the Sixteenth Century, Koenigsberger and Mosse, Holt Rinehart Publishers, 1968, page 50)

Debt repudiations in several places in the 1550s are described like this:

“This caused the first big international bank crash, for the Antwerp bankers now could not meet their own obligations.”

(Europe in the Sixteenth Century, Koenigsberger and Mosse, Holt Rinehart Publishers, 1968, page 51)

This sounds like some kind of identifiably global period.

Actually, modern historians define globalization as “price convergence” (i.e., wheat has now a unified “world price,” implying a world market). This rigorous definition is confirmed by and also shows up in the data in the 1820s and may or may not be prefigured by all the Marco Polo and Atocha silver stories, mentioned above.

These episodes in history are not there yet.

One sees wheat prices and other commodity prices converging in the 1820s and thereafter based on railroads, steamships and telegrams.

The classic in this kind of analysis is:

Globalization and History: The Evolution of a Nineteenth-Century Atlantic Economy, by Kevin O’Rourke and Jeffrey Williamson.

Kevin O’Rourke and Jeffrey Williamson present a coherent picture of In Globalization and History, Kevin O’Rourke and Jeffrey Williamson present a coherent picture of trade, migration, and international capital flows in the Atlantic economy in the century prior to 1914—the first great globalization boom, which anticipated the experience of the last fifty years. The authors estimate the extent of globalization and its impact on the participating countries, and discuss the political reactions that it provoked. The book’s originality lies in its application of the tools of open-economy economics to this critical historical period—differentiating it from most previous work, which has been based on closed-economy or single-sector models. The authors also keep a close eye on globalization debates of the 1990s, using history to inform the present and vice versa. The book brings together research conducted by the authors over the past decade—work that has profoundly influenced how economic history is now written and that has found audiences in economics and history, as well as in the popular press.

(book summary)

In everyday language, we associate the word globalization with some ever-increasing Marco Polo phenomena. While that’s not entirely wrong, globalization in the more technical sense begins to show up in the data only from the 1820s. At this point, we begin to see the convergence of worldwide wheat prices, for example. This makes the world, for the first time, a global “store” with unified prices. Here is the technical beginning of globalization. The years 1870-1914 are subsequently the first real era of modern globalization and represent a kind of “take-off” from the first stirrings of the 1820s. World Wars I & II might be seen as globalization backlash.

At this moment in world history, whether Putin’s invasion of Ukraine will constitute a new wave of deglobalization remains to be seen.

From ASEAN and G20 to APEC, as World Leaders Meet in Person Again, 3 Reasons to Root for Multilateralism

By Wang Huiyao | Founder of the Center for China and Globalization (CCG)

Over the past two weeks, Asia has played host to the most intense sequence of multilateral summits since the pandemic began, as national leaders gathered for meetings organized by ASEAN, the G20 and APEC. Although overshadowed by geopolitical tensions, the meetings marked a welcome return to in-person summit diplomacy, and the better-than-expected outcomes show hope yet for multilateralism.

The conclaves began in Phnom Penh with the annual summit of the Association of Southeast Asian Nations. At the first of such in-person events in almost three years, ASEAN leaders took the positive step of agreeing in principle to admit East Timor as the 11th member of the organization.

As leaders moved on to Bali for the Group of 20 summit, expectations were low after ministerial meetings in the run-up had failed to produce consensus. Earlier in the year, given fractures in the wake of Russia’s invasion of Ukraine, there was a question mark over whether the G20 could even go ahead or survive in its existing form.

In the end, the summit surpassed expectations by producing a joint declaration after intense negotiations, with leaders finding the compromises necessary to unite in declaring that “today’s era must not be of war” and pledging to uphold the multilateral system.

The summit also saw a positive face-to-face meeting between China’s President Xi Jinping and U.S. President Joe Biden, their first as leaders, signaling a willingness to halt the downward trajectory of China-U.S. relations.

In Bangkok, the 21 leaders of the Asia-Pacific Economic Cooperation forum also pledged to uphold and strengthen the rules-based multilateral trading system. Importantly, the group agreed on a multi-year work plan for an Asia-Pacific free trade area.

Reflecting on these three summits, three takeaways give reason for cautious optimism that multilateralism can yet be revived and play a major role in solving our challenges.

First, and perhaps most obviously, the return of in-person summit diplomacy is a welcome uplift for global cooperation. Virtual formats played a useful interim role at the height of the pandemic but were never a substitute for getting leaders in the same room. That is especially when it comes to interactions on the sidelines, often as important as the main event.

China’s return to diplomacy at the highest level was a further boost, both for the nation and the rest of the world.

In addition to Xi’s highly anticipated meeting with Biden, the Chinese leader met over a dozen other leaders at the G20 and APEC summits, including a warmer-than-expected first meeting with Japanese Prime Minister Fumio Kishida and his first meeting with an Australian prime minister since 2016.

Leaders got to meet their new counterparts for the first time or build on existing relationships, which can only help global cooperation.

The second takeaway is that as grave as our challenges are, the threat of escalating conflict and severe economic pressures on all nations seem to be focusing minds and increasing the willingness to engage and cooperate—out of necessity if nothing else.

The G20 summit was the second major one this year to surpass expectations after the 12th World Trade Organization Ministerial Conference in June surprised observers by agreeing on a plan to reform the organization and its dispute settlement mechanism. The G20 statement reiterated support for this WTO reform plan, which will be critical to get the free trade agenda back on track and provide a much-needed boost for the global economy.

Third, and perhaps most significantly for the long term, the recent summits marked an acceleration of the trend towards multi-polarization in international diplomacy, and in particular, the rising influence of non-aligned “middle powers” to shape multilateral outcomes.

The middle powers represented at ASEAN, the G20 and APEC have huge stakes in avoiding a bifurcation of the global economy that might result from a new cold war. They don’t want to be forced to pick sides and many show a growing willingness and ability to build bridges and restore positive momentum for multilateralism.

Indonesia is a prime example. The country’s strategic heft and non-aligned credibility make it well-placed to bridge different camps. President Joko Widodo made a big political bet on the success of the G20 and has won praise for the deft diplomacy that kept the organization alive and got it to a joint statement.

The Indian delegation reportedly also played a big role in achieving consensus on language in the statement, with the BRICS group (Brazil, Russia, India, China and South Africa)—as well as Indonesia—turning out to be crucial swing voters in securing the joint statement. One Indian official said it was “the first [G20] summit where developing nations shaped the outcome.”

There is scope for this trend to continue next year as middle powers continue to rise in stature, and India and Indonesia take over the presidency of the G20 and ASEAN, respectively. Brazil will host the G20 the year after.

Over in Sharm el-Sheikh at the COP27 UN climate summit, another middle power—the host Egypt—also won praise for helping to shepherd a historic financing deal for poor countries affected by climate change. But the ultimate failure to reach a commitment to phase down fossil fuels was a sobering reminder of the huge difficulties that remain in forging the global consensus needed to overcome our shared challenges.

Education and Circular Causation: Everything Causes Everything Else

The student will have seen in these educational essays the notion of “Husserl’s rhomboid”:

The great philosopher, Edmund Husserl, who died in 1938, would bring a matchbox to class and show his students they see parts and some surface area of the matchbox (a kind of rhomboid, hence the name “Husserl’s rhomboid”) but never all of it at the same time. Students can walk around the matchbox and see facets. They can twirl the matchbox but whatever they do, the students cannot “espy” or glimpse all of it except in their imaginations, once they have been exposed to all of it, side by side, facet by facet.

Gunnar Myrdal, the Swedish economist who won the Nobel Prize in 1974, has something a bit analogous when he speaks of “circular cumulative causation”:

Circular cumulative causation is a theory developed by Swedish economist Gunnar Myrdal in 1956. It is a multi-causal approach where the core variables and their linkages are delineated. The idea behind it is that a change in one form of an institution will lead to successive changes in other institutions. These changes are circular in that they continue in a cycle, many times in a negative way, in which there is no end, and cumulative in that they persist in each round. The change does not occur all at once, which would lead to chaos, rather the changes occur gradually.

Gunnar Myrdal developed the concept from Knut Wicksell and developed it with Nicholas Kaldor when they worked together at the United Nations Economic Commission for Europe.

In the characteristics relevant to an economy’s development process, Myrdal mentioned the availability of natural resources, the historical traditions of production activity, national cohesion, religions and ideologies, and economic, social and political leadership.

He writes:

“The notion of stable equilibrium is normally a false analogy to choose when constructing a theory to explain the changes in a social system.

What is wrong with the stable equilibrium assumption as applied to social reality is the very idea that a social process follows a direction—though it might move towards it in a circuitous way—towards a position which in some sense or other can be described as a state of equilibrium between forces. Behind this idea is another and still more basic assumption, namely that a change will regularly call forth a reaction in the system in the form of changes which on the whole go in the opposite direction to the first change. The idea I want to expound in this book is that, on the contrary, in the normal case there is no such a tendency towards automatic self-stabilisation in the social system. The system is by itself not moving towards any sort of balance between forces, but is constantly on the move away from such a situation. In the normal case a change does not call forth countervailing changes but, instead, supporting changes, which move the system in the same direction as the first change but much further. Because of such circular causation as a social process tends to become cumulative and often gather speed at an accelerating rate…”

(Gunnar Myrdal, Economic Theory and Underdeveloped Regions, Gerald Duckworth, 1957, pp. 12–13)

Myrdal developed further the circular cumulative causation concept and stated that it makes different assumptions from that of stable equilibrium on what can be considered the most important forces guiding the evolution of social processes. These forces characterize the dynamics of these processes in two diverse ways.

These essays that you are reading here are examples encouraging students to put causes in a kind of circle: history exists because economics exists because psychology exists because society exists because history exists. Everything is causing everything else. There isn’t a simple “linear parade.”

By way of contrast, in a person’s private life, he/she went to the dentist before buying the batteries and after having lunch. There’s a timeline of events.

In history, there are such linear timelines also: John Kennedy was assassinated before Donald Trump became president. You had breakfast before dinner. You slept before you got up in the morning.

However, processes (industrialism, migration, urbanization, inflation, etc.) are not analyzable as events like meals and one-time occurrences but are more like getting old or learning a language.

Multi-causal interpretations and circular causes get the student out of simple, “this happened and that happened” in favor of “this and that caused each other, going both ways and interacting with other pressures too.” Everything is causing and altering everything else in all directions.
