A diversified firm can trade at a discount to a matched portfolio of single-segment firms if the diversified firm has either lower expected cash flows or higher expected returns than the single-segment firms. We study whether firms with diversification discounts have higher expected returns in order to compensate investors for offering less upside potential (or skewness exposure) than focused firms. Our empirical tests support this hypothesis. First, we find that focused firms offer greater skewness exposure than diversified firms. Second, we find that diversified firms have significantly larger discounts when the diversified firm offers less skewness than matched single-segment firms. Finally, we find that up to 53% of the excess returns received on diversification-discount firms relative to diversification-premium firms can be explained by differences in exposure to skewness.

We examine the wealth effects of 3 regulatory changes designed to improve minority-shareholder protection in the Chinese stock markets. Using the value of a firm’s related-party transactions as an inverse proxy for the quality of corporate governance, wefind that firms with weaker governance experienced significantly larger abnormal returns around announcements of the new regulations than did firms with stronger governance. We also find that firms with strong ties to the government did not benefit from the regulations, suggesting that minority shareholders did not expect regulators to enforce the new rules on firms where blockholders have strong political connections.

This paper investigates the relation between information on the state of the economy and equity risk premium. We use a setup where investors have Epstein-Zin preferences and the economy randomly switches between booms and recessions. We are able to establish 2 key results: First, investors with high elasticity of intertemporal substitution (EIS) will require lower excess returns for holding stocks if they are provided with better information on the state of the economy. Second, we find that this also holds for investors with moderate EIS if they are sufficiently risk averse.

We develop a financial market trading model in the tradition of Glosten and Milgrom (1985) that allows us to incorporate nontrivial volume. We observe that in this model price volatility is positively related to the trading volume and to the absolute value of the net order flow (i.e., the order imbalance). Moreover, higher volume leads to higher order imbalances. These findings are consistent with well-established empirical findings. Our model further predicts that higher trader participation and systematic improvements in the quality of traders’ information lead to higher volume, larger order imbalances, lower market depth, shorter duration, and higher price volatility.

We develop an equilibrium model in a 2-country, 2-good, pure exchange economy in which investors with logarithmic utility functions have heterogeneous beliefs about exogenously given output or endowment processes. We obtain closed-form representations of real exchange rates and of stock prices. We show that heterogeneous beliefs together with heterogeneous preferences make the volatility of real exchange rates and of stocks exhibit some properties that have been well documented in the empirical literature. These properties include the high volatility of both real exchange rates and stocks compared with that of economic fundamentals, the high correlation of stocks during periods of volatile markets. The model can also generate the clustering of the volatility of foreign exchange rates and stocks if the differences of beliefs are clustering.

Using an extensive cross section of U.S. corporate credit default swaps (CDSs), this paper offers an economic understanding of implied loss given default (LGD) and jumps in default risk. We formulate and underpin empirical stylized facts about CDS spreads, which are then reproduced in our affine intensity-based jump-diffusion model. Implied LGD is well identified, with obligors possessing substantial tangible assets expected to recover more. Sudden increases in the default risk of investment-grade obligors are higher relative to speculative grade. The probability of structural migration to default is low for investment-grade and heavily regulated obligors because investors fear distress rather through rare but devastating events.

Recent evidence indicates that momentum profits are sensitive to market conditions. We find that the profits are higher when the markets continue in the same state than when they transition to a different state. These findings support Daniel, Hirshleifer, and Subrahmanyam (1998), who suggest that investor overconfidence is higher when the markets continue in the same state (UP or DOWN) than when they reverse, predicting higher momentum profits in the former. In contrast, our evidence following DOWN markets is not consistent with the other competing models for the market-state conditional momentum profits.

The value of American options depends on the exercise policy followed by option holders. Market frictions, risk aversion, or a misspecified model, for example, can result in suboptimal behavior. We study the sensitivity of American options to suboptimal exercise strategies. We show that this measure is given by the Gamma of the American option at the optimal exercise boundary. More precisely, “if B is the optimal exercise price, but exercise is either brought forward when or delayed until a price B̃ has been reached, the cost of suboptimal exercise is given by ½ × Γ(B) × (B − B̃)2, where Γ(B) denotes the American option Gamma.” Therefore, the cost of suboptimal exercise is second-order in the bias of the exercise policy and depends on Gamma. This result provides new insights on American options.
