Have We Underestimated the Likelihood and Severity of Zero Lower Bound Events?

Prior to the financial crisis, most economists probably did not view the zero lower bound (ZLB) as a major problem for central banks. Using a range of structural and statistical models, we find that previous research understated the ZLB threat by ignoring uncertainty about model parameters and latent variables, focusing too much on the Great Moderation experience, and relying on structural models whose dynamics cannot generate sustained ZLB episodes. Our analysis also suggests that the Federal Reserve's asset purchases, while materially improving macroeconomic conditions, did not prevent the ZLB constraint from having first‐order adverse effects on real activity and inflation.     

Cost of Equity and S&P 500 Index Revisions

We examine how the cost of equity changes when firms are added to or removed from the S&P 500 Index during index revisions. Newly added firms experience a significant decline in the cost of equity, while recently removed firms show a significant increase. Liquidity improves for addition firms and declines for removed firms. Addition firms also experience a decline in shadow cost. Changes in cost of equity for included firms are explained by changes in liquidity, shadow cost, and firm size. Finally, included firms with greater investment opportunities benefit more from the reduction in cost of capital.     

A New Method for Identifying the Effects of Foreign Exchange Interventions

Central banks react even to intraday changes in the exchange rate; however, in most cases, intervention data are available only at a daily frequency. This temporal aggregation makes it difficult to identify the effects of interventions on the exchange rate. We apply the Bayesian Markov‐chain Monte Carlo (MCMC) approach to this endogeneity problem. We use “data augmentation” to obtain intraday intervention amounts and estimate the efficacy of interventions using the augmented data. Applying this new method to Japanese data, we find that an intervention of 1 trillion yen moves the yen/dollar rate by 1.8%, which is more than twice as much as the magnitude reported in previous studies applying ordinary least squares to daily observations. This shows the quantitative importance of the endogeneity problem due to temporal aggregation.     

The Effect of Regulation on Insurance Pricing: The Case of Germany

This article analyzes the impact of policy form regulation on the unit price of insurance and determinants of premium changes using the 1994 deregulation of the German property–liability market as a natural experiment. Our result show that policy form regulation did not increase prices above competitive levels. Factors influencing premium changes are significantly different for the two time periods, pre‐ and post‐deregulation, indicating that regulation affects insurance pricing. Focusing on highly competitive lines after deregulation, we find a significant price decrease, and this decrease is offset by higher prices in the remaining other lines.     

What's in a “China” Name? A Test of Investor Attention Hypothesis

We study whether a firm's name affects investor attention and firm valuation. Some Chinese firms listed on US stock exchanges have the word “China” included in their company names (“China‐name stocks”), while others do not (“non‐China‐name stocks”). During the 2007 China stock market boom, we find that China‐name stocks significantly outperform non‐China‐name stocks. This is not due to differences in firm characteristics, risk, or liquidity. The “China‐name effect” is largely consistent with the investor attention hypothesis that price pressure caused by increased investor attention on China‐name stocks during the boom period drives up China‐name stocks more than non‐China‐name stocks.     

The Displacement Effect of Public Pensions on the Accumulation of Financial Assets*

The generosity of public pensions may depress private savings and provide incentives to retire early. While there is plenty of evidence supporting the latter effect, there remains considerable controversy over whether public pensions crowd out private savings. This paper uses international micro‐data sets collected over recent years to investigate whether public pensions displace private savings. The identification strategy relies not only on cross‐country differences in generosity but also on differences in the progressivity or non‐linearity of pension formulas across countries. We estimate that an extra dollar of pension wealth depresses accumulated financial assets around the time of retirement by 22 cents. An extra 10,000 dollars in public pension wealth reduces the average retirement age by roughly one month, which implies an elasticity of years of retirement with respect to pension wealth of 0.15.     

Quand les analystes ajustent‐ils leurs évaluations en fonction du biais des annonces de résultats prévisionnels ? Conséquences de la feuille de route des entreprises en ce qui a trait à la publication de résultats prévisionnels et enjeux motivant les analystes

Les études précédentes indiquent que les analystes n’ajustent pas totalement leurs évaluations en fonction du biais général à la baisse des annonces de résultats prévisionnels faites par les directions d’entreprises. Les auteurs rapportent les résultats de deux expériences visant à déterminer comment la feuille de route des entreprises en ce qui a trait à la publication de résultats prévisionnels et les enjeux motivant les analystes expliquent de concert la mesure dans laquelle ces derniers ajustent leurs évaluations en fonction du biais des annonces de résultats prévisionnels. Ces résultats d’expérience semblent indiquer que les analystes pour qui l’enjeu est celui de l’exactitude ajustent leurs évaluations selon la feuille de route de la direction en ce qui a trait à la publication de résultats prévisionnels biaisés à la baisse lorsque le biais est relativement modeste (un cent), mais que les analystes pour qui l’enjeu est celui de leur relation avec la direction s’en abstiennent. Au surplus, la différence dans l’ajustement est plus importante lorsque la feuille de route de l’entreprise en matière de biais est irrégulière que lorsqu’elle est régulière. Aussi, lorsque le biais des annonces de résultats prévisionnels est plus important que moins (deux cents par rapport à un cent), les analystes pour qui l’enjeu est celui de la relation avec la direction procèdent à un ajustement partiel, paraissant ainsi rechercher un équilibre entre exactitude et volonté de plaire à la direction. Ces constatations ont des répercussions pour les investisseurs, les autorités de réglementation et l’interprétation des études précédentes.

Who Are the Potential Smokers of Smuggled Cigarettes?

Although smuggled cigarettes have been a prevalent problem and a severe challenge to public health and welfare around the world, little is known about the behavior associated with smoking smuggled cigarettes and the issue is difficult to study due to data limitations. By means of a population‐based tobacco survey conducted in Taiwan, the present paper applies a latent class model to identify potential smokers who are either currently or will at some point in the future be consuming smuggled cigarettes. This methodology, in contrast to the traditional discrete models, allows potential smokers who are more inclined to smoke smuggled cigarettes to be endogenously classified. The empirical results indicate that socio‐demographic factors do increase the inclination to smoke smuggled cigarettes after unobserved heterogeneity has been accounted for.
