Higher Order Effects in Asset Pricing Models with Long‐Run Risks

This paper shows that the latest generation of asset pricing models with long‐run risk exhibit economically significant nonlinearities, and thus the ubiquitous Campbell‐Shiller log‐linearization can generate large numerical errors. These errors translate in turn to considerable errors in the model predictions, for example, for the magnitude of the equity premium or return predictability. We demonstrate that these nonlinearities arise from the presence of multiple highly persistent processes, which cause the exogenous states to attain values far away from their long‐run means with nonnegligible probability. These extreme values have a significant impact on asset price dynamics.     

Social Capital,Trust, and Firm Performance: The Value of Corporate Social Responsibility during the Financial Crisis

During the 2008–2009 financial crisis, firms with high social capital, as measured by corporate social responsibility (CSR) intensity, had stock returns that were four to seven percentage points higher than firms with low social capital. High‐CSR firms also experienced higher profitability, growth, and sales per employee relative to low‐CSR firms, and they raised more debt. This evidence suggests that the trust between a firm and both its stakeholders and investors, built through investments in social capital, pays off when the overall level of trust in corporations and markets suffers a negative shock.     

It's SHO Time! Short-Sale Price Tests and Market Quality

We examine the effects of the Securities and Exchange Commission (SEC)-mandated temporary suspension of short-sale price tests for a set of Pilot securities. While short-selling activity increases both for NYSE- and Nasdaq-listed Pilot stocks, returns and volatility at the daily level are unaffected. NYSE-listed Pilot stocks experience more symmetric trading patterns and a slight increase in spreads and intraday volatility after the suspension while there is a smaller effect on market quality for Nasdaq-listed Pilot stocks. The results suggest that the effect of the price tests on market quality can largely be attributed to distortions in order flow created by the price tests themselves.     

Hidden costs of consumption

Consumers often underestimate the costs resulting from their consumer decisions. This is especially the case when purchasing durable consumer goods, but also for recreational activities, for which e.g. athletic equipment is bought. A similar situation exists when pets are kept. This disregard for the costs of subsequent use connected with the purchase of household appliances is problematic for consumers. In a study on the usage life of consumer goods¹ in the household, it was recognized that many consumers do not pay attention to these subsequent costs. The decisive consumer problem was not the durability of consumer goods, nor their tendency to become defective, but the resulting costs of the purchase, the operating costs of household appliances. On one hand, the working expenses are not considered at the time of purchase and their effect is not included in the purchase decision. On the other, the operating costs vary greatly, depending on the chosen type and model of appliance and, of course, on the specific form of utilization. In this paper, the question of the durability of consumer goods is first discussed with the help of empirical work. Then the hidden resulting costs, i.e. operating costs or costs of usage of consumer goods, are described. The resulting costs of keeping pets are also discussed. In the final part, the question of objective help for the consumer making purchase decisions is discussed.     

Feeding the British: convergence and market efficiency in the nineteenth-century grain trade

This paper traces the evolution of the international market for wheat, from an emerging market structure after the repeal of the corn laws to a mature market characterized by efficient arbitrage after the introduction of the transatlantic telegraph and the growth of trade. Efficiency is documented using traditional price gap accounting as well as error correction modelling. Markets which traded directly with each other as well as markets which did not trade with each other were integrated. The traditional bilateral focus in market integration studies has been extended to a multivariate approach, which generates new insights into the pattern of diffusion of price shocks in the international economy. Shocks in the major importing nation, Britain, dominated in the emerging market phase, while shocks in the major exporting economy, the United States, dominated international price movements at the end of the nineteenth century.     

Transparency,Liquidity, and Valuation: International Evidence on When Transparency Matters Most

We examine the relation between firm‐level transparency, stock market liquidity, and valuation across countries, focusing on whether the relation varies with a firm's characteristics and economic environment. We document lower transaction costs and greater liquidity (as measured by lower bid‐ask spreads and fewer zero‐return days) for firms with greater transparency (as measured by less evidence of earnings management, better accounting standards, higher quality auditors, more analyst following, and more accurate analyst forecasts). The relation between transparency and liquidity is more pronounced in periods of high volatility, when investor protection, disclosure requirements, and media penetration are poor, and when ownership is more concentrated, suggesting that firm‐level transparency matters more when overall investor uncertainty is greater. Increased liquidity is associated with lower implied cost of capital and with higher valuation as measured by Tobin's Q. Finally, a mediation analysis suggests that liquidity is a significant channel through which transparency affects firm valuation and equity cost of capital.     

Are Some Forecasters Really Better Than Others?

In any data set with individual forecasts of economic variables, some forecasters will perform better than others. However, it is possible that these ex post differences reflect sampling variation and thus overstate the ex ante differences between forecasters. In this paper, we present a simple test of the null hypothesis that all forecasters in the U.S. Survey of Professional Forecasters have equal ability. We construct a test statistic that reflects both the relative and absolute performance of the forecaster and use bootstrap techniques to compare the empirical results with the equivalents obtained under the null hypothesis of equal forecaster ability. Results suggest little support for the idea that the best forecasters are actually innately better than others, though there is evidence that a relatively small group of forecasters perform very poorly.     

On Price Caps Under Uncertainty

This paper shows how standard arguments supporting the imposition of price caps break down in the presence of demand uncertainty. In particular, though in the deterministic case the introduction or lowering of a price cap (above marginal cost) results in increased production, increased total welfare, decreased prices, and increased consumer welfare, we show that all of the above comparative statics predictions fail for generic uncertain demand functions. For example, for price caps sufficiently close to marginal cost, a decrease in the price cap always leads to a decrease in production and total welfare under certain mild conditions. Under stronger regularity assumptions, all of the monotone comparative statics predictions from the deterministic case also do not hold for a generic uncertain demand if we restrict attention to price caps in an arbitrary fixed interval (as long as the price caps are binding for some values in that interval).
