摘要：This paper presents an equilibrium model of the term structure of interest rates when investors have heterogeneous preferences. The basic model considers a pure exchange economy of two classes of investors with different (but constant) relative risk aversion and gives closed-form solutions to bond prices. I use the model to examine the effect of preference heterogeneity on the behavior of bond yields. The model is also extended to cases of more than two classes of investors.

摘要：We examine the relation between exchange rate variability and stock return volatility for U.S. multinational firms and decompose this relation into components of systematic and diversifiable risk. Focusing on two five-year periods around the 1973 switch from fixed to floating exchange rates, we find a significant increase in volatility of monthly stock returns corresponding to the period of increased exchange rate variability, even relative to the increase in stock return volatility for three ...

摘要：This paper develops a generalized regime-switching (GRS) model of the short-term interest rate. The model allows the short rate to exhibit both mean reversion and conditional heteroskedasticity and nests the popular generalized autoregressive conditional heteroskedasticity (GARCH) and square root process specifications. The conditional variance process accommodates volatility clustering and dependence on the level of the interest rate. A first-order Markov process with state-dependent transiti...

摘要：This paper re-examines the efficiency of foreign currency futures markets by evaluating the role of time-varying risk premia and volatility in explaining technical trading rule profits. The results show that large parts of the technical rule profits can be explained by the time-varying risk premia estimated from a general model for the conditional CAPM; The bootstrap distributions for the profits under the null model average one-third to one-half of the actual profits and enclose the actual pr...

摘要：Underwriters have an incentive to overstate investor interest in order to persuade some investors to purchase shares at a price in excess of their initial estimate of the fair value. We show that this incentive is eliminated when the underwriter commits to secondary market price stabilization. Destroying the underwriter's incentive to overstate interest reduces the total surplus captured by initial investors in initial public offerings. Further efficiency gains are associated with penalty bid ...

摘要：This research evaluates methods used in event studies that employ accounting-based measures of operating performance. We examine the choice of an accounting-based performance measure, a statistical test, and a model of expected operating performance. We document the impact of these choices on the test statistics designed to detect abnormal operating performance. We find that commonly used research designs yield test statistics that are misspecified in cases where sample firms have performed ei...

摘要：When commercial banks make loans to firms and also underwrite securities, does this hamper or enhance their role as certifiers of firm value? This paper examines empirically the pricing of bank-underwritten securities as compared to investment-house-underwritten securities over a unique period in the U.S. (pre-Glass-Steagall) when both banks and investment houses were allowed to underwrite securities. The evidence shows that investors were willing to pay higher prices for securities underwritt...

摘要：We investigate whether investors price the option to abandon a firm at its exit value. Theory prices this real option as an American put with both a stochastic strike price (exit value) and a stochastic value of the underlying security (the value of cash flows). The empirical implications are that firm value increases in exit value, after controlling for expected going-concern cash flows, and that more generalizable assets produce more abandonment option value. Using discounted earnings foreca...

摘要：Recent studies argue that implicit collusion explains the tendency of Nasdaq market makers to avoid odd-eighth price quotes. This paper focuses on the role that preference trading plays in determining quoted spreads, Under the postulated effects of preference trading, an analysis of the relation between spreads and price fractions explains the paucity of odd-eighth quotes on Nasdaq. Empirical results from a comprehensive data set show that exogenous economic characteristics explain the distrib...
