Knowledge that Transforms

Abstract This paper conducts empirical tests in a conditional setting for 10 developed and 12 emerging markets to determine whether emerging market currency risk is priced and if it spills over into developed market assets. Our empirical model is based on real exchange rate measures and it allows currency risk to compete with broader economic and political risks. We find that emerging market currency risk is priced separately from other local risk factors and that it represents a significant component of equity returns in both developed and emerging markets. We also find that the spillover impact is heightened during emerging market crisis episodes and affects the expected compensation for global risks.

Abstract We study securities market models with fixed costs. We first characterize the absence of arbitrage opportunities and provide fair pricing rules. We then apply these results to extend some popular interest rate and option pricing models that present arbitrage opportunities in the absence of fixed costs. In particular, we prove that the quite striking result obtained by Dybvig, Ingersoll, and Ross (1996), which asserts that under the assumption of absence of arbitrage long zero-coupon rates can never fall, is no longer true in models with fixed costs, even arbitrarily small fixed costs. For instance, models in which the long-term rate follows a diffusion process are arbitrage-free in the presence of fixed costs (including arbitrarily small fixed costs). We also rationalize models with partially absorbing or reflecting barriers on the price processes. We propose a version of the Cox, Ingersoll, and Ross (1985) model which, consistent with Longstaff (1992), produces yield curves with realistic humps, but does not assume an absorbing barrier for the short-term rate. This is made possible by the presence of (even arbitrarily small) fixed costs.

Abstract This paper investigates whether the size and book-to-market factors of Fama and French (1993) proxy for the risks associated with business cycle fluctuations. We find that changes in default spread (Δ def ) and changes in term spread (Δ term ) capture the systematic differences in average returns along the size and book-to-market dimensions in the way that the Fama-French factors do: small stock portfolios have higher loadings on Δ def than large stock portfolios, while high book-to-market portfolios have higher loadings on Δ term than low book-to-market portfolios. Furthermore, in the presence of Δ def and Δ term , the Fama-French factors are superfluous in explaining the size and book-to-market effects. The results suggest that the size and value premiums are compensation for higher exposure to the risks related to changing credit market conditions and interest rates proxied by Δ def and Δ term .

Abstract In this paper, we examine the relation between stock returns and analysts' heterogeneous expectations. We find that stock returns are positively associated with divergence of opinion. Our evidence provides no support for Miller's (1977) overvaluation hypothesis, which predicts lower (higher) future returns for high (low) divergence of opinion stocks in the presence of short-selling constraints. Our findings are based on the use of the diversity measure, which is free from the confounding effects of uncertainty in analysts' forecasts and is therefore a more accurate measure of divergence of opinion than dispersion. Our results refute the view that dispersion in analysts' forecasts reflects divergence of opinion. Our evidence is robust to the use of alternative measures of short-selling constraints, time intervals, optimism in analysts' forecasts, and herding in analysts' behavior.

Abstract Prior research posits that market imperfections and the lack of institutions that protect investor interests create a divergence between the cost of internal and external funds, thereby constraining firms' ability to fund investment projects through external financing. Financial constraints force firms to manage their cash flows to finance potentially profitable projects. A related stream of research documents that financial constraints due to costly external financing are more pronounced in underdeveloped financial markets. We examine the influence of financial development on the demand for liquidity by focusing on how financial development affects the sensitivity of firms' cash holdings to their cash flows. Using firm-level data for 35 countries covering about 12,782 firms for the years 1994–2002, we find the sensitivity of cash holdings to cash flows decreases with financial development. We also consider additional implications of firms' cash flow sensitivity of cash with respect to firm size and business cycles. Overall, we provide new cross-country evidence of the role of financial development on financial constraints.

Abstract This study provides further evidence of earnings management around security offerings. We find positive and significant discretionary current accruals coincident with offerings of reverse LBOs. Issuers in the most aggressive quartile of earnings management have a one-year aftermarket return that is between 15% and 25% less than the most conservative quartile. We also find a negative and significant relation between abnormal accruals and post-issue abnormal returns within the first year after the offering. The relation remains after controlling for book-to-market ratio, firm size, offering size, and involvement of buyout specialists or management. Although earnings management has been used to explain post-issue long-term underperformance of IPOs and SEOs, our study shows that earnings management can explain post-offering returns of reverse LBOs, even in the absence of post-offering underperformance.

Abstract We build a structural two-factor model of default where the stock market index is one of the stochastic factors. We allow the firm to adjust its leverage ratio in response to changes in the business climate for which the past performance of the stock market index acts as a proxy. We assume that the firm's log-leverage ratio follows a mean-reverting process and that the past performance of the stock index negatively affects the firms target leverage ratio. We show that for most credit ratings our model may explain actual yield spreads better than other well-known structural credit risk models. Also, our model shows that the past performance of the stock index returns and the firm's assets beta have a significant impact on credit spreads. Hence, our model can explain why credit spreads may be different within the same credit rating groups and why spreads are lower during economic expansions and higher during recessions.

Abstract This study uses a large sample of firms to examine how human capital considerations affect the process of CEO succession. Costs and benefits of succession planning are affected by a firm's level of operational complexity and human capital requirements; firms that are more complex incur greater costs to transferring firm-specific knowledge and expertise to an outsider, and should be more likely to groom an internal candidate for the CEO position. Consistent with this, I find that a firm's propensity to groom an internal candidate for the CEO position is related to firm size, degree of diversification, and industry structure. My results also suggest that succession planning is associated with a higher probability of inside succession and voluntary succession and a lower probability of forced succession. I also provide evidence that horizon problems are mitigated to some extent by having a succession plan.

Abstract This paper examines the value of analysts as industry specialists. We show analysts create value in their recommendations mainly through their ability to rank stocks within industries. An industry-based recommendation strategy substantially improves the return to risk ratio and reduces price momentum tilt relative to portfolios that ignore industry information. An examination of the links among analyst information, aggregated at the industry level, and industry returns and industry momentum shows that industry returns precede industry-aggregated analyst upgrades and downgrades, and the short-term industry price momentum phenomenon is partly explained by returns of firms with more analyst coverage leading those with less in that industry. Recommendation information is not valuable for predicting future relative industry returns, however.

Abstract We study the dynamic relation between daily stock returns and daily innovations in optionderived implied volatilities. By simultaneously analyzing innovations in index- and firmlevel implied volatilities, we distinguish between innovations in systematic and idiosyncratic volatility in an effort to better understand the asymmetric volatility phenomenon. Our results indicate that the relation between stock returns and innovations in systematic volatility (idiosyncratic volatility) is substantially negative (near zero). These results suggest that asymmetric volatility is primarily attributed to systematic market-wide factors rather than aggregated firm-level effects. We also present evidence that supports our assumption that innovations in implied volatility are good proxies for innovations in expected stock volatility.
