The Life and Philosophy of Martin Rees

An Interview with Martin Rees

Astronomer Royal and best-selling science author, Martin Rees pioneering early work led to evidence to contradict the Steady State theory of the universe and confirm the Big Bang. His influence then spread to the wider public—knighted in 1992, elevated to Baron in 2005, then giving the Reith Lectures in 2010. Most recently his attention has turned from the early universe to the future of humanity. In this interview, Lord Rees discusses the ideas and experiences which led to such an illustrious career.

Xi Risks Losing the Middle Class

The zero-COVID strategy has run its course

Kerry Brown | Professor of Chinese Studies and Director of Lau China Institute, King’s College London. He is the co-editor of the Journal of Current Chinese Affairs, and author of Xi: A Study in Power.

China is continuing with its tough zero-COVID policy. But the cracks in the economy and a discontent middle class mean that Xi’s Imperial-like governing style is under challenge, writes Kerry Brown.

China’s zero-COVID strategy operates in Chinese domestic politics a bit like Brexit does in the UK. Despite complaints from business networks and broader society about the negative impact on economic growth and citizens’ freedoms, it’s a policy commitment the government is sticking to no matter what.

Of course, no one voted for the draconian lockdowns implemented across China. And, unlike Brexit, the lockdowns are very much in line with expert advice in the country, rather than running against it. The Chinese Centre for Disease Control and Prevention (CCDC), the main governmental body advising the government over crisis response in this area, said in a weekly update last November that without comprehensive restraints on people’s movement and quarantines on anyone testing positive for the virus, the national health system would soon be overwhelmed with cases, and find itself in the same bind as those in the US or Europe did.

That the words of the experts have been taken so much in earnest is striking for a regime that previously hasn’t been shy to dismiss them. The Xi leadership may be confident in the way it speaks to the outside world, but it seems that it has the same profound wariness in the robustness of the country’s public health as everywhere else. Things have not been helped by clinical trials showing the Chinese vaccines – the only ones accepted in China – are not as effective as foreign ones where the length of protection is in question). On top of this, vaccine take-up by the elderly, the most vulnerable group, has been poor. It is easy to see therefore why the central government might be very cautious. What is harder to understand, however, is why the cautiousness has bordered on obsessiveness.

The Xi way of governing is increasingly almost imperial in style, with broad, high-level policy announcements made in Beijing, sometimes of almost Delphic succinctness.

One scenario is simply about the structures of decision-making in China. This was an issue right from the moment the variant started to appear in late 2019, and local officials in Wuhan stood accused of trying to hush the issue up, delaying reporting to the central authorities till things had already gone on too long. As a result of this, in February 2020 key officials in the city were sacked. But this is unlikely to change the fact that provincial officials are very risk averse under Xi, and that any central direction to manage the pandemic will be interpreted in the purest terms and executed to the letter.

This explains the completeness of the Xian government’s virtual incarceration of its 8 million population after just a few COVID cases at the end of 2021, the first of the more recent lockdowns. It also explains why the traditionally more free-thinking municipal authority of Shanghai and its similarly liberal approach was fiercely knocked back by Beijing last February, to make an example for any other provinces thinking of going their own way. The absolute prohibition on people moving from their homes there, in one of the most dynamic and lively cities of modern China, was perfect proof that if the government could bring about this situation there, it could do it anywhere.

This case study also reveals some important things about the Xi way of governing. It is increasingly almost imperial in style, with broad, high-level policy announcements made in Beijing, sometimes of almost Delphic succinctness, which are then handed down to various levels of government to do as they will. Exactly how and when the discussion amongst Xi and his Politburo colleagues on the best response to COVID happened is unclear. In a world where almost every political system seems to leak incessantly, the Chinese one is unique in maintaining its opacity and secretiveness – no mean achievement in the social media era.

The Communist Party is very aware of how relatively small incidents can mount up and then generate overwhelming force. It itself coined the Chinese phrase ‘a single spark can start a prairie fire.’

Rumors of clashes between Xi and his premier Li Keqiang on the effectiveness of the current response remain just that – rumors, with precious little hard evidence to back them up. Who in the current imperial system might dare to speak from the ranks and say that policy must change is unclear. Scientists should deal in hard facts – but we all know that science is susceptible to politicization. Experts in China have to offer their expertise in a highly political context. A declaration that the current approach is not fit for purpose can easily be reinterpreted as an attempt to launch an indirect attack on the core leader. With an important Congress coming up later this year, at which Xi is expected to be appointed for another five years in power, sensitivities are even more intense than normal. It is little wonder that the COVID strategy status quo settled on last year has not shifted.

Things, however, may well change, and change quickly. China is moving into tricky economic territory. The impact of the pandemic on global supply chains, along with the various stresses domestically on the housing market, and productivity, have shrunk expectations for growth. A predicted 6% in the earlier part of the year now looks overly ambitious. There is a real possibility China might experience a recession. At a moment like this, the government, which after all operates as a constant crisis and risk management entity, might do what it does best and prompt rapid, and dramatic, changes.

The handling of COVID-19 might look like further proof that Chinese politics under Xi is repressive and zero-sum. But even in an autocratic state like the current People’s Republic, the pandemic will not leave politics unchanged.

This doesn’t mean that China’s COVID-19 bind gets any easier. Like the country’s serious demographic challenges, with a rapidly aging population, the only thing the government will be picking an argument with is reality as it proceeds into the future. As with Europe and the US, being more liberal about facing COVID-19 will involve accepting some of the harsh consequences – rising fatalities, particularly for the elderly and vulnerable, and health systems put under enormous stress. In such a huge, complex country, and of enormous geopolitically importance, a misstep could easily lead to huge and unwanted consequences, generating discontent and triggering mass protests in a way reminiscent of 1989. The Communist Party is very aware of how relatively small incidents can mount up and then generate overwhelming force. It itself coined the Chinese phrase ‘a single spark can start a prairie fire.’ One such spark – the introduction of Marxism into China in the 1910s – led to its gaining of power three decades later.

The handling of COVID-19 might look like further proof that Chinese politics under Xi is repressive and zero-sum. But I suspect that even in an autocratic state like the current People’s Republic, the pandemic will not leave politics unchanged. In particular, the middle classes in cities like Shanghai have had their patience tested in recent months. This is the key group for Xi, the heart of his new innovative, more self-dependent, higher-quality service sector workers in an urbanized economy. Their support remains crucial if Xi is able to steer China towards the moment when it hopes it will become the world’s largest economy. Policies to try to placate them by addressing imbalances, critical environmental issues and improving public health are likely to only increase. Delivery however will be key.

Faced with a potentially life-threatening infectious disease, the Party can throw out injunctions and claim it has been the victim of bad luck. But an ailing economy and no clear signs of the government knowing how to manage this will prove a toxic mixture for it. Xi and his third term in office will be all about delivery. The question is whether, even with the formidable suite of powers he has, he can do this. Governing China has always been the ultimate political challenge. COVID-19 has made that even harder.

OFR Working Paper Finds Cash Biases Measurement of the Stock Return Correlations

[from the U.S. Office of Financial Research]

Today, the U.S. Office of Financial Research published a working paper, “Cash-Hedged Stock Returns” [archived PDF], and an accompanying blog (below), regarding firms’ cash holdings and the implications for asset prices and financial stability.

Cash holdings are important for financial stability because of their value in crises.  Corporate cash piles vary across companies and over time. Firms’ cash holdings typically earn low returns, and their cash returns are correlated across firms.  Thus, the asset pricing results are important for investors managing a portfolio’s risk and policymakers concerned about sources of vulnerability.

The working paper [archived PDF] shows how investors can hedge cash on firms’ balance sheets when making portfolio choices.  Cash generates variation in beta estimates, and the working paper decomposes stock betas into components that depend on the firm’s cash holding, return on cash, and cash-hedged return. Common asset pricing premia have large implicit cash positions, and portfolios of cash-hedged premia often have higher Sharpe ratios, used by investors to understand a return on investment, because of the correlation between firms’ cash returns. The paper shows the value of a dollar increased in 2020, and firms hold cash because they are riskier.

OFR Finds Large Cash Holdings Can Lead to Mismeasuring Risk

[from the OFR blog, by Sharon Ross]

Cash is necessary for companies’ operations. Firms use cash to make payments, finance investments, and manage risk. But holding cash comes at a cost: its low pecuniary return. Published today by the OFR, the working paper, “Cash-Hedged Stock Returns” [archived PDF], shows that the cash returns of publicly traded, non-financial firms are correlated. Since cash returns are a part of equity returns, investors that are using equity return correlations to measure risk can mismeasure risk.

We show the importance of cash for systemic risk by documenting the value of cash in crises, showing that firms hold cash in part due to risk management and studying how cash biases the measurement of the interconnectedness of stock returns. The consequences of cash are important for policymakers monitoring aggregate risks, and sources of market vulnerability and for investors making portfolio choices.

Cash holdings are important for financial stability because of their value in crises. Several papers document a “dash for cash” during the initial panicked stages of the coronavirus 2019 (COVID-19) pandemic when firms rushed to hold cash in their coffers. The dash for cash was driven by firms drawing down on lines of credit from banks, which in turn affected bank lending. The dash for cash highlighted the critical role of firms’ cash holdings and returns in understanding risk in the financial system.

We show the value of a dollar increased in 2020. Moreover, our results show that firms may hold cash because they are riskier, as opposed to firms with high cash shares being less risky due to their cash holdings. Our results are consistent with a precautionary savings motive for holding cash. In other words, firms hold cash for risk management, in part to weather bad times.

Cash is a growing share of public firmsassets. The value-weighted U.S. stock market held 22% of its assets in cash in December 2020 compared to 8% in the 1980s. An investor buying the market in 2020 ends up with an implicit cash position three times larger than in 1980. Individual firms vary in how much cash they hold. As cash holdings increase, it is important to understand how cash holdings affect returns, which in turn impacts who chooses to invest in the firms.

Cash returns are correlated across firms, and cash biases measurement of the interconnectedness of stock returns, making it a risk for financial stability. As a result, the asset pricing results are important both for investors managing portfolio risk and for policymakers concerned about interconnected returns.

We argue that the value of corporate cash is distinct, and we can separate the value of cash and the value of the firm’s primary business. We show how investors can explicitly account for the effect of corporate cash holdings when forming a portfolio. When an investor owns stock in a company with substantial cash, the investor has an implicit cash position managed by the company—something the investor might not intend. We argue that investors should account for the effect of corporate cash holdings in the portfolio decision to measure a portfolio’s risk. Firms’ cash management is not consistent across firms, and investors may want to manage their cash positions themselves. Policymakers should be aware of investors’ choices in cash because of investorsportfolio risk and the implications for aggregate risk.

We separate a company’s stock return into its cash and non-cash components, and we show that using the non-cash return gives a more informative correlation structure across stocks. In other words, if investors take out the correlated cash returns, the remaining return is less correlated, yielding portfolios that provide better diversification. We show how cash holdings and returns affect the returns of standard asset pricing strategies and asset pricing models like the capital asset pricing model (CAPM).

As cash holdings of public firms increase, it is important that policymakers understand how these increases impact stock returns for both individual firms and the aggregate market. Cash returns are correlated across firms, and cash biases the measurement of the interconnectedness of stock returns. This correlation is important both for investors who are managing a portfolio’s risk and policymakers concerned about sources of vulnerability stemming from interconnected returns.

Essay 58: Machlup and Knowledge-Watching

Fritz Machlup is an underappreciated emigre economist from Vienna. His 1962 book, The Production and Distribution of Knowledge in the United States (Princeton University Press, 1962), is a “bible” of knowledge-watching and the zones where knowledge meets information, where Machlup was very prescient.

Fritz Machlup was an Austrian-American economist who was president of the International Economic Association from 1971–1974.  He was one of the first economists to examine knowledge as an economic resource, and is credited with popularizing the concept of the information/knowledge society.

Born: December 15, 1902, Wiener Neustadt, Austria
Died: January 30, 1983, Princeton, NJ

Machlup distinguishes five types of knowledge:

  1. Practical knowledge
  2. Intellectual knowledge
  3. Small-talk and pastime knowledge
  4. Spiritual knowledge
  5. Unwanted knowledge

These five kinds of knowledge are discussed and analyzed in Machlup’s The Production and Distribution of Knowledge in the United States starting on page 21 (and are discussed in Daniel Bell’s The Coming of Post Industrial Society, 1976, Basic Books, page 175).

The more comfortably one can link types 1, 2, and 4 in the list above, the more “together” one’s understanding might become.  One does not have to be “dismissive” of Type 3.

Pleasant diversions are a a part of life and have their honorable place. One reason (to give a simple example) we’re drawn to poets like Wallace Stevens is that they seem to “sit comfortably” in their various (knowledge) roles: insurance salesman, poet, thinker and don’t “line up” or “array” these types of knowledge in a conflictual way but seem to “smile down” on all of them finding beauty everywhere.

Workaday knowledge might not have to “fight with” other kinds of knowledge. Insurance, say, is a form of risk-management and risk is essential to life and economics, as we have seen elsewhere.  Economics looks at cost-benefitrisk-uncertainty all together when it goes beyond the narrow confines of academe to become a fuller quest.  Cost-benefit analysis by itself is too restrictive.  Start with Machlup as a highly intelligent “backdoor” into these domains of knowledge, information, learning, social contexts.  This would help give you a handy additional “flashlight” on schooling in society including universities and campuses.

Essay 52: Economics Reconsidered to Include Uncertainty

Standard definitions for economics say that it is about “cost-benefit” thinking. Everything costs time or money or effort or lost opportunities but offers different levels of expected benefit.  Economics, in this view, matches decisions to this “menu” of items and prices.

Actually, that is not a complete description at all because economics is about cost-benefitrisk-uncertainty thinking and that implies one needs to get into the dimensions of risk and uncertainty. 

A real decision involves more than costs and benefits but implies all kinds of “how can I be sure?” questions which means risk and uncertainty considerations

World-watching modified in this way is explored at policyuncertainty.com (Kellogg School of Management, Northwestern University)

This implies the need for new indicators such as:

Call for papers:  “Uncertainty and Economic Activity:  Global Perspectives” [PDF]

The extraordinary rise in trade policy uncertainty [archived PDF].

Policy News and Stock Market Volatility [PDF].

They say that practitioners of a field are always like general “fighting the last war” not this one, like the French generals in 1940 who were mentally in 1914. 

One must augment all economics textbook talk in this direction of risk-and-uncertainty without which all analyses are like backward-looking “stills” as opposed to forward-looking “moving pictures.”  All standard textbooks are uninformative on these issues.
