摘要：The paper first characterizes the predictable components in excess rates of returns on major equity and foreign exchange markets using lagged excess returns, dividend yields, and forward premiums as instruments. Vector autoregressions (VARs) demonstrate one-step-ahead predictability and facilitate calculations of implied long-horizon statistics, such as variance ratios. Estimation of latent variable models then subjects the VARs to constraints derived from dynamic asset pricing theories. Exami...

摘要：An annual loss is essentially a necessary condition for dividend reductions in firms with established earnings and dividend records: 50.9% of 167 NYSE firms with losses during 1980-1985 reduced dividends, versus 1.0% of 440 firms without losses. As hypothesized by Miller and Modigliani, dividend reductions depend on whether earnings include unusual items that are likely to temporarily depress income. Dividend reductions are more likely given greater current losses, less negative unusual items,...

摘要：We examine whether greater futures-trading activity (volume and open interest) is associated with greater equity volatility. We partition each trading activity series into expected and unexpected components, and document that while equity volatility covaries positively with unexpected futures-trading volume, it is negatively related to forecastable futures-trading activity. Further, though futures-trading activity is systematically related to the futures contract life cycle, we find no evidenc...

摘要：Periodic antitrust attacks on corporations may have influenced stock prices. For the period 1904 to 1944, each antitrust case filed is associated with a 0.5 to 1.9 percent drop of the Dow, and each unexpected case with even larger drops. Other aspects of antitrust besides actual filings may help account for other movements, in particular the 1929 Crash. Historical evidence bears on the question of whether antitrust is exogenous and also links antitrust and the ''corporation problem.'' These re...

摘要：This paper analyzes how the daily opening and closing of financial markets affect trading volume. We model the desire to trade at the beginning and end of the day as a function of overnight return volatility. NYSE data from 1933-88 indicate that closing volume is positively related to expected overnight volatility, while volume at the open is positively related to both expected and unexpected volatility from the previous night. We interpret the symmetric response of trading at the open and the...

摘要：We characterize the conditions under which efficient portfolios put small weights on individual assets. These conditions bound mean returns with measures of average absolute covariability between assets. The bounds clarify the relationship between linear asset pricing models and well-diversified efficient portfolios. We argue that the extreme weightings in sample efficient portfolios are due to the dominance of a single factor in equity returns. This makes it easy to diversify on subsets to re...

摘要：We analyze personal open market trades by managers around stock repurchases by tender offer. With the exception of Dutch auction offers, managers trade their firm's shares prior to repurchase announcements as though repurchases convey favorable inside information to outsiders. Prior to fixed price repurchase offers that do not follow takeover-related events, managers increase their buying and reduce their selling of their firm's shares. Prior to repurchases that follow takeover-related events,...

摘要：Grinblatt and Titman (1985) reformulate a result of Chamberlain and Rothschild (1983) to show that the approximate factor structure of Chamberlain and Rothschild is asymptotically equivalent to the strict factor structure of Ross (1976) as long as investors can always repackage securities into an equal number of arbitrary portfolios. This paper uses a Procrustes rotation methodology that is compatible with the repackaging interpretation of Grinblatt and Titman to show that the empirical struct...

摘要：We adapt a contingent claims model of the firm to reflect the incentive effects of the capital structure and thereby to measure the agency costs of debt. An underlying model of the firm and the stochastic features of its product market are analyzed and an optimal operating policy is chosen. We identify the change in operating policy created by leverage and value this change. The model determines the value of the firm and its associated liabilities incorporating the agency consequences of debt.

摘要：While the U.S. has pursued a vigorous antitrust policy towards horizontal mergers over the past four decades, mergers in Canada have until recently been permitted to take place in a virtually unrestricted antitrust environment. The absence of an antitrust overhang in Canada presents an interesting opportunity to test the conjecture that the rigid market share and concentration criteria of the U.S. policy effectively deters a significant number of potentially collusive mergers. The effective de...
