Knowledge that Transforms

We investigate corporate financial policies in the presence of both temporary and permanent shocks to firms’ cash flows. In our framework, cash flows can be negative and are imperfectly correlated with firm value, and earnings volatility differs from asset volatility. These results are consistent with empirical stylized facts. They are also contrary to the implications of existing dynamic capital structure models that allow only for permanent shocks to cash flows. Temporary shocks increase the importance of financial flexibility and may provide an intuitively simple and realistic explanation of empirically observed financial conservatism and low leverage phenomena. The theoretical framework developed in this article general enough to be used in various corporate finance applications.

This article examines how price risk affects housing demand. It identifies two relevant channels: a financial risk effect that reduces demand, and a hedging effect that increases demand since current homes may hedge future housing costs. The latter dominates when hedging incentives are strong, namely when the likelihood of moving up the housing ladder is high and the tendency to move across markets is low. For households with weak hedging incentives, the article finds negative effects of price risk on the timing and size of home purchases, but positive effects for households with strong hedging incentives.

This article examines the optimal CEO compensation and replacement policy when the CEO is privately informed about the firm’s continuation value under his leadership. Ex ante moral hazard implies that the CEO must receive ex post quasi rents, which endogenously biases him toward continuation. Our model shows that to induce “bad” CEOs to quit, it may be best to make continuation costly (through steep incentive pay) rather than simply rewarding quitting (through severance pay). Incentive pay makes continuation attractive for “good” CEOs, who can expect high future on-the-job pay, but unattractive for “bad” CEOs, who may instead prefer to take their outside option payoff. Our model generates novel empirical implications that jointly relate CEO compensation and turnover to corporate governance, firm size, cash-flow risk, and the informativeness of performance measurement.

Bank loans

We develop a dynamic incomplete-markets model of entrepreneurial firms, and demonstrate the implications of nondiversifiable risks for entrepreneurs' interdependent consumption, portfolio allocation, financing, investment, and business exit decisions. We characterize the optimal capital structure via a generalized tradeoff model where risky debt provides significant diversification benefits. Nondiversifiable risks have several important implications: More risk-averse entrepreneurs default earlier, but choose higher leverage; lack of diversification causes entrepreneurial firms to underinvest relative to public firms, and risky debt partially alleviates this problem; and entrepreneurial risk aversion can overturn the risk-shifting incentives induced by risky debt. We also analytically characterize the idiosyncratic risk premium.

We construct a firm-level governance index that increases with minority shareholder protection. Compared with U.S. matching firms, only 12.68% of foreign firms have a higher index. The value of foreign firms falls as their index decreases relative to the index of matching U.S. firms. Our results suggest that lower country-level investor protection and other country characteristics make it suboptimal for foreign firms to invest as much in governance as U.S. firms do. Overall, we find that minority shareholders benefit from governance improvements and do so partly at the expense of controlling shareholders.

This article studies performance-sensitive debt (PSD), the class of debt obligations whose interest payments depend on some measure of the borrower’s performance. We demonstrate that the existence of PSD obligations cannot be explained by the trade-off theory of capital structure, as PSD leads to earlier default and lower equity value compared to fixed-rate debt of the same market value. We show that, consistent with the pecking-order theory, PSD can be used as an inexpensive screening device, and we find empirically that firms choosing PSD loans are more likely to improve their credit ratings than firms choosing fixed-interest loans. We also develop a method to value PSD obligations allowing for general payment profiles and obtain closed-form pricing formulas for step-up bonds and linear PSD.

We analyze theoretically and empirically the implications of information asymmetry for equilibrium asset pricing and portfolio choice. In our partially revealing dynamic rational expectations equilibrium, portfolio separation fails, and indexing is not optimal. We show how uninformed investors should structure their portfolios, using the information contained in prices to cope with winner’s curse problems. We implement empirically this price- contingent portfolio strategy. Consistent with our theory, the strategy outperforms economically and statistically the index. While momentum can arise in the model, in the data, the momentum strategy does not outperform the price-contingent strategy, as predicted by the theory.

Nous prsentons les rsultats d'une tude portant sur l'valuation de crances ventuelles de style europen pour une grande varit de caractristiques lies au rendement des actifs sousjacents. Les rsultats de notre valuation proposent en temps discret une formule tat-espace infinie, partir du principe de non-arbitrage et d'une mesure de martingale quivalente. Notre approche permet de tenir compte de formes gnrales d'htroscdasticit dans les rendements et d'obtenir, dans des cas spciaux, des rsultats d'valuation lis aux processus homoscdastiques. Elle permet aussi de considrer les innovations conditionnellement non normales en matire de rendement, ce qui reprsente un facteur critique, compte tenu du fait que l'htroscdasticit ne permet pas, elle seule, de saisir pleinement le caractre ironique de l'option. Nous analysons une catgorie de mesures de martingale quivalentes dont la dynamique du rendement risque-neutre obtenu est de la mme famille de distribution que la dynamique du rendement physique. Dans ce cas, notre cadre d'tude soutient les rsultats d'valuation obtenus par Nous tendons ces rsultats aux mesures de martingale quivalentes plus gnrales et aux modles de volatilit stochastique en temps discret et analysons aussi la relation entre nos rsultats et ceux obtenus dans le cas des modles en temps continu.

In a market with informationally connected traders, the dynamics of volume, price informativeness, price volatility, and liquidity are severely affected by the information linkages every trader experiences with his peers. We show that in the presence of information linkages among traders, volume and price informativeness increase. Moreover, we find that information linkages improve or damage market depth, and lower or boost the Traders' profits, according to whether these linkages convey positively or negatively correlated signals. Finally, our model predicts patterns of trade correlation consistent with those identified in the empirical literature: trades generated by “neighbor” traders are positively correlated and trades generated by “distant” traders are negatively correlated.
