Abstract This study tests whether belief differences affect the cross-sectional variation of risk-neutral skewness using data on firm-level stock options traded on the Chicago Board Options Exchange from 2003 to 2006. We find that stocks with greater belief differences have more negative skews, even after controlling for systematic risk and other firm-level variables known to affect skewness. Factor analysis identifies latent variables linked to risk and belief differences. The belief factor explains more variation in the risk-neutral skewness than the risk-based factor. Our results suggest that belief differences may be one of the unexplained firm-specific components affecting skewness.

Abstract An intermarket sweep order (ISO) is a limit order that automatically executes in a designated market center even if another market center is publishing a better quotation. An investor submitting an ISO must satisfy order protection rules by concurrently submitting orders to the markets with better prices. We find that ISOs represent 46% of trades and 41% of volume in our sample. ISO trades have a significantly larger information share despite their small trade size relative to non-ISO trades. Post trade return analysis suggests that informed institutions are the main users of ISO trades.

Abstract This paper presents the first theoretical analysis of the choice of firms between “preparing” and not preparing the equity market in advance of a possible dividend cut. In our model, insiders have private information about their firm’s intermediate cash flow as well as about the net present value of its growth opportunity. We show that, in equilibrium, firms in temporary financial difficulties but with good long-term growth prospects are more likely to prepare the market in advance of dividend cuts, while those with permanently declining earnings are less likely to prepare the market. Our model generates several new testable predictions.

Abstract I study the relation between corporate diversification and labor productivity in a sample of over 500,000 firms from 46 countries. Across the entire sample, greater diversification is associated with significantly lower labor productivity. The negative relation between diversification and labor productivity is not stronger in countries with more burdensome employment regulation, but it is significantly stronger in countries with better financial development. In addition, the negative relation is stronger in industries with high capital/labor ratios. Overall, the results suggest that the lower productivity in diversified firms is due more to the misallocation of capital than to the inefficient use of labor.

Abstract Using a comprehensive sample of U.S. mutual funds from 1992 to 2004, we find strong evidence that investment bank-affiliated funds underperform unaffiliated funds. Consistent with the conflict of interest hypothesis, we find that affiliated funds hold disproportionately large amounts of stocks of their initial public offering and seasoned equity offering clients. Moreover, worse-performing clients are more likely to be held by affiliated funds. Our results are robust to alternative risk adjustments, portfolio weighting schemes, and regression methodologies. Overall, our findings are consistent with the idea that investment banks use affiliated funds to support underwriting business at the expense of fund shareholders.

Abstract Model selection (i.e., the choice of an asset pricing model to the exclusion of competing models) is an inherently misguided strategy when the true model is unavailable to the researcher. This paper illustrates the advantages of a model pooling approach in characterizing the cross section of stock returns. The optimal pool combines models using the log predictive score criterion, a measure of the out-of-sample performance of each model, and consistently outperforms the best individual model. The benefits to model pooling are most pronounced during periods of economic stress, and it is a valuable tool for asset allocation decisions.

Abstract This paper examines whether a firm’s reputation is a determinant of repurchase completion rates (the ratio of actual to announced repurchases) and whether the stock market discounts announcements made by less reputable firms. Prior completion rates are positively correlated with current completion rates and announcement returns, suggesting consistency in repurchases and implying a reputational effect. Further, a nascent literature regarding accelerated share repurchases (ASRs) finds them to be more credible than open market repurchases. I show that the probability of announcing an ASR is greater for firms likely to be concerned about reputation because of low past completion rates.

Abstract We examine aggregate idiosyncratic volatility in 23 developed equity markets, measured using various methodologies. We find no evidence of upward trends after extending the sample to 2008. Instead, idiosyncratic volatility is well described by a stationary autoregressive process that occasionally switches into a higher-variance regime that has relatively short duration. We also document that idiosyncratic volatility is highly correlated across countries. Most of the time variation in idiosyncratic volatility can be attributed to variation in a growth opportunity proxy, total (U.S.) market volatility, and in most specifications, the variance premium, a business cycle sensitive risk indicator.

Abstract We find that equity mispricing impacts the speed at which firms adjust to their target leverage (TL) and does so in predictable ways depending on whether the firm is over- or underlevered. For example, firms that are above their TL and should therefore issue equity (or retire debt) adjust more rapidly toward their target when their equity is overvalued. However, when a firm is undervalued but needs to reduce leverage, the speed of adjustment is much slower. Our findings support the role of equity mispricing as an important factor that alters the cost of making capital structure adjustments.

Abstract I evaluate whether the so-called long-run risk framework can jointly explain key features of both equity and bond markets as well as the interaction between asset prices and the macroeconomy. I find that shocks to expected consumption growth and time-varying macroeconomic volatility can account for the level of risk premia and its variation over time in both markets. The results suggest a common set of macroeconomic risk factors operating in equity and bond markets. I estimate the model using a simulation estimator that accounts for time aggregation of consumption growth and utilizes a rich set of moment conditions.
