Degrowth,the past,the future,and the human nature

In the last years, different sources point to a same message: industrial civilization has entered an overshoot mode, the natural limits to growth have been already surpassed. This frontier does not wait for us in the future; it already belongs to our past. If population and the economy are truly beyond the limits, then current visions and theories of social change would be deeply perturbed. If the development era is approaching its end, then many sociological theories on current societies will share the same destiny, sustainable development doctrines between them. It is worth to examine theories that explicitly look at the social world this way or that – at least – are not incompatible with it. Differences between these theories depend on sociological, psychological and anthropological questions; or, in other words, they depend on the human nature. Exploring the relationship between degrowth and the human nature gives rise to debates about selective pressures under conditions of scarcity (human evolution), historical and anthropological evidence, philosophy, and sociology (institutional resilience, utopies as whole society experiments…). As its conclusion, the argument accepts that an evolutionary perspective supports that there are some potentials for conscious social change even in a way-down era, but it does not justify the belief in a particular only line of history. This conclusion does not satisfy the desire of knowing the future; nevertheless it may be the only one possible. The future is not written. Neither in history nor in evolution; not even in the mixture of history and evolution that conforms us as inhabitants of the Earth.     

Banks,the IMF,and the Asian crisis

This paper examines the impact of the Asian crisis on bank stocks. In the second half of 1997, Western banks outperformed their stock markets. In contrast, East Asian bank indices incurred losses in excess of 60% in each of the crisis countries. Most of these poor performances are explained by stock market movements in the crisis countries. After taking into account these movements, currency exposures affected banks adversely only in Indonesia and the Philippines. Except for the Korean program, which affected positively bank stocks in all countries in our sample but one, IMF programs had little effect on bank values.     

Middlemen: the good,the bad,and the ugly

We examine the role of a middleman as an expert in markets. A seller's effort determines the quality of the good. Buyers observe neither the seller's effort nor the good's quality. A middleman, after observing a signal about the good's quality, decides whether to purchase it and then to sell it. We show that the presence of a middleman may either reduce or exacerbate the seller's moral hazard problem. We also consider a model with multiple middlemen. We find that the seller's effort is minimized if either the middleman's signal is perfect or the number of middlemen is large.     

Predicting anomaly performance with politics,the weather,global warming,sunspots, and the stars

Predictive regressions find that the party of the US president, the weather in Manhattan, global warming, the El Niño phenomenon, sunspots, and the conjunctions of the planets all have significant power predicting the performance of popular anomalies. The interpretation of these results has important implications for the asset pricing literature.     

Investor wealth,the IMF,and the Asian crisis

This study further investigates the impact of IMF actions on stock markets during the Asian crisis. Extending two earlier studies by Kho and Stulz (2000) and Evrensel and Kutan (2007), we investigate the long-term shareholder wealth impact of IMF actions and programs on both financial and real sector returns in the stock markets of Thailand, Indonesia, and Korea. We perform a series of tests employed in Cornett and Tehranian (1989, 1990) that incorporate heteroscedasticity across sectors and contemporaneous dependence of the disturbances. The findings indicate that IMF actions regarding liquidity disbursement or liquidity concerns in markets are the most important events affecting abnormal returns and hence investor wealth in both real and financial sectors. However, the response of the financial sector to IMF actions is much stronger than that of the real sector. In addition, the results suggest moral hazard effects during the Asian crisis in all the three countries.     

Expectations,the exchange rate,and the current account

A critical examination is undertaken of the relationship between the exchange rate and the current account in a small open economy. Theoretically, the correlation between the exchange rate and the current account seems to be ambiguous. In particular, the association between movements in the exchange rate and the current account is likely to depend in an essential manner on the nature of exogenous disturbances affecting the two variables simultaneously. Lastly, the question of the role of an optimal monetary policy and the choice of an exchange rate regime in an uncertain environment is raised.     

Time-to-build, time-to-plan, habit-persistence, and the liquidity effect

The inability of sticky-price monetary business cycle models to generate liquidity effects has been extensively documented by a number of authors. This paper develops a sticky-price monetary business cycle model with investment gestation lags and habit-persistence in consumption that is capable of generating an empirically plausible liquidity effect.     

Monetary shocks, the exchange rate, and the trade balance

This paper investigates the response of the exchange rate and the trade balance to monetary policy innovations for the US economy during the period 1973:01–1993:12. The empirical findings indicate that contractionary monetary policy shocks lead to transitory appreciations of the real and the nominal exchange rate. Exchange rate appreciations that are caused by a temporary contractionary shock to monetary policy are correlated with a short-lived improvement in the trade balance which is then followed by a deterioration, giving support to the J-curve hypothesis.     

Dating,discounting, and the robustness of the Lucas-Sargent proposition

From recent work by Thomas Sargent and others, it has become well known that, if expectations are formed rationally, monetary stabilization policy will be entirely ineffective in an economy in which the aggregate supply function relates output (relative to capacity) to the difference between the current price level and the value expected one period earlier. This paper considers whether this neutrality proposition holds when the expectation of some future price is compared with the current actual price in the supply equation. It is shown that the proposition remains valid if the future price is appropriately discounted.     

Entry, exit, market makers, and the bid-ask spread

The probability of entry and exit of dealers on the NASDAQ NationalMarket (NNM) is significantly affected by trading intensity,volatility and the quoted bid-ask spread. Entry and exit ofmarket makers is a pervasive phenomenon. Large-scale entry (exit)is associated with substantial declines (increases) in quotedend-of-day inside spreads, even after controlling for the effectsof changes in volume and volatility. The spread changes arelarger in magnitude for issues with few market makers; however,even for issues with a large number of market makers, substantialchanges in quoted spreads take place. The results are consistentwith the competitive model of dealer pricing.     

Bookbuidling, Auctions, and the Future of the IPO Process

Auction theorists predict that bookbuilding, long the standard process for selling equity IPOs in the U.S., is about to give way to an Internet‐based IPO auction process that is both more efficient and more fair. The promise of auctions is that, by using an electronic platform that gives all investors the opportunity to bid on IPOs, the underpricing of IPOs and commissions to underwriters will be reduced, leading to an increase in net proceeds to issuers. Largely missing from such arguments, however, is an appreciation of why bookbuilding has dominated U.S. practice (and continues to supplant auctions in IPOs in most countries outside the U.S) and the role of undepricing in the IPO process. Rather than canvassing all investors, bookbuilding involves eliciting expressions of interest from institutional investors, and then allocating shares mainly according to the strength of their professed interest. In contrast to auctions, which allocate shares according to a set of explicit rules, bookbuilding involves a set of implicit “rules” that provide considerable room for judgment by the underwriter. This does not mean that the rules are arbitrary or not well understood by participants, particularly after thousands of IPOs conducted over the better part of two centuries. But to manage the exchange of information between issuers and investors, and the potential conflicts of interest in representing both groups, such rules must be administered by an intermediary with a considerable stake in protecting its reputation for fair dealing. Investment banks that deal with both issuers and the investment community on a regular basis are well positioned to perform this function. The underpricing of IPOs is best viewed not as a transfer of wealth from issuers to favored investors but rather as compensation to the large influential investors that play a major role in the price discovery process. By opening the process to all comers, auctions will discourage these large investors from bidding aggressively because less sophisticated investors will be able to “free ride” on their research and due diligence. To the extent this happens, auctions may suc ceed in reducing underpricing (in fact, they may even lead to over pricing), but they will also reduce the net proceeds for issuers. Nevertheless, recent advances in communications technology and auction theory will undoubtedly reshape current securities underwriting practices. In particular, Internet auctions are likely to replace bookbuilding in debt IPOs and less risky equity issues (say, IPOs of LBOs). But the argument that Bookbuilding will be completely cast aside in favor of largely untested alternatives fails to appreciate a successful institutional response to major market imperfections, some of which can never be wholly eliminated. Especially in the case of risky (first‐time) equity IPOs, there will continue to be an important role for managing the information exchange between issuers and investors that is critical to the IPO process.     

Liquidity,the Value of the Firm,and Corporate Finance

The theory of corporate finance has been based on the idea that a company's market value is determined mainly by just two variables: the company's expected after‐tax operating cash flows or earnings, and the risk associated with producing them. The authors argue that there is another important factor affecting a company's value: the liquidity of its own securities, debt as well as equity. The paper supports this argument by reviewing the large and growing body of evidence showing that differences—and changes—in liquidity can have major effects on the pricing of corporate stocks and bonds or, equivalently, on investors' required returns for holding them. The authors also suggest that the liquidity of a company's securities can be managed by corporate policies and actions. For those companies whose value is likely to be increased by having more liquid securities—which is by no means true of all companies (mature firms that don't need outside capital may well benefit from having more concentrated ownership and hence less liquidity)—management should consider actions such as reducing leverage and substituting dividends for stock repurchases as well as measures designed to increase the effectiveness of their disclosure and investor relations program and the size of their investor base.     

Obesity,Mortality, and the Obesity Paradox

The percentage of the population who are obese has grown dramatically on a worldwide basis over the last several decades, although the growth in the prevalence of obesity has slowed recently at a high level in the United States. Although there have been numerous studies of the effect of this trend on mortality, the findings have been inconsistent and controversial, in part because of methodological differences and the complexity of the relationships between obesity and mortality. The objective of this article is to discuss the issues surrounding these relationships and to shed light on the likely effects of the obesity epidemic on mortality. Of particular interest is the so-called obesity-mortality paradox, where mortality experience is lower for overweight and in some cases obese individuals than for those of normal weight. Although more recent studies of the relationship between mortality and obesity seem to indicate those who are obese have experienced a reduced percentage of additional mortality, this may in part be due to the shorter average time those currently obese have been exposed to their condition, the heterogeneity of the normal and obese populations, measurement issues including treatment of smokers and those who are ill, and study design limitations. An increased number of premature deaths may arise as more individuals who are obese are exposed for a longer period to excess adiposity. Although public policy issues surrounding obesity are being addressed with a great deal of activity and publicity, they have and will continue to prove quite challenging for both individuals and society to manage and overcome. The prevalence of obesity has had and will continue to have a significant effect on the mortality experience in most areas of actuarial practice. As a result, it is important for actuaries to enhance their understanding of these effects.     

Volatility,the Macroeconomy,and Asset Prices

How important are volatility fluctuations for asset prices and the macroeconomy? We find that an increase in macroeconomic volatility is associated with an increase in discount rates and a decline in consumption. We develop a framework in which cash flow, discount rate, and volatility risks determine risk premia and show that volatility plays a significant role in explaining the joint dynamics of returns to human capital and equity. Volatility risk carries a sizable positive risk premium and helps account for the cross section of expected returns. Our evidence demonstrates that volatility is important for understanding expected returns and macroeconomic fluctuations.     

Banks, Bears, and the Financial Crisis

We test whether short selling is destabilizing comparing distressed financial firms to other firms using NYSE transactions records covering 4 years including the recent financial crisis. Aggressive short-selling is sometimes destabilizing by some measures, but its impact is small, vanishes quickly, is not necessarily larger for distressed firms or during the crisis, and is accompanied by other stabilizing effects. The evidence does not validate theoretical predictions from models of destabilizing speculative or predatory trading. Aggregate short-selling is largely unrelated to market-wide investor sentiment, credit risk, and ex ante volatility. Aggressive liquidation of long positions typically has more impact than short selling. Thus, the data cannot justify the restrictions on short sales of financial stocks imposed in September 2008.     

Monetary Policy,Neutrality, and the Environment

We study the interaction between monetary/fiscal policies in a Ramsey–Sidrauski model augmented with the “Green Golden Rule.” We demonstrate conditions whereby monetary and fiscal policy under different utility and preference assumptions are or are not environmentally neutral. Despite its nonseparability in utility, we demonstrate that money is environmentally neutral. Policy impacts the environment via the marginal rate of transformation rather than the marginal rate of substitution between consumption and environment. Fiscal policies under a balanced budget are environmentally nonneutral. Only under a nonbalanced budget, when deficits are monetized, is money environmentally nonneutral. Under cash-in-advance and transactions costs, money is environmentally nonneutral.     

Consumption,Credit, and the Missing Young

There are more young adults today with either no credit history or insufficient credit history to be scored by one of the major credit bureaus than there were before the Great Recession—a reality that is likely an outcome of the Credit Card Accountability Responsibility and Disclosure (CARD) Act of 2009–10. In regressions that include a rich set of controls, we show that measures of young adults missing a credit score in credit bureau data act as a drag on state-level consumption growth. We demonstrate that this effect is driven by young people's loss of access to credit since the legislation went into effect.
