This paper develops tests of unconditional mean‐variance efflciency under weak distributional assumptions using a Generalized Method of Moments framework. These tests are potentially more robust than commonly employed tests which rely on the assumption that asset returns are normally distributed and temporarily i.i.d. Using returns for size‐based portfolios from 1926 to 1988 we show that the conclusion concerning the mean‐variance effilciency of market indexes can be sensitive to the test considered.

This paper studies the relation between changes in financial investment opportunities and changes in the macroeconomy. States variables such as the lagged production growth rate, the default premium, the term premium, the short‐term interest rate and the market dividend‐price ratio are shown to be indicators of recent and future economic growth. Further, the market excess return is negatively correlated with recent economic growth and positively correlated with expected future economic growth. These results offer straightforward interpretations of recent evidence on the forecasts of the market excess return by state variable via their forecasts on the macroeconomy.

A positive slope of the yield curve is associated with a future increase in real economic activity: consumption (nondurables plus services), consumer durables, and investment. It has extra predictive power over the index of leading indicators, real short‐term interest rates, lagged growth in economic activity, and lagged rates of inflation. It outperforms survey forecasts, both in‐sample and out‐of‐sample. Historically, the information in the slope reflected, inter alia, factors that were independent of monetary policy, and thus the slope could have provided useful information both to private investors and to policy makers.

The presence of any friction in financial markets qualitatively changes the nature of the optimization problem faced by an investor. It requires one to either act or do nothing, an issue which, of course, does not arise in frictionless situations. The investor considered here accumulates wealth without consuming until some terminal point in time when he consumes all. His objective is to maximize the expected utility derived from that terminal consumption. We postpone the terminal point far into the future to obtain a stationary portfolio rule. The portfolio policy is in the form of two control barriers between which portfolio proportions are allowed to fluctuate. We show how to calculate them.

We characterize the exchange of financial claims from risky swaps. These transfers are among three groups: shareholders, debtholders, and the swap counterparty. From this analysis we derive equilibrium swap rates and relate them to debt market spreads. We then show that equilibrium swaps in perfect markets transfer wealth from shareholders to debtholders. In a simplified case, we obtain closed‐form solutions for the value of the default risk in the swap. For interest‐rate swaps, we obtain numerical solutions for the equilibrium swap rate, including default risk. We compare these with equilibrium debt market default risk spreads.

We study the price elasticity of demand for the common stock of an individual corporation. Despite the prevelance of assumptions that demand is perfectly elastic, there is little if any direct evidence in the literature to either support or reject that contention. Consistent with the notion of finite price elasticities, we find that the announcement of primary stock offerings by regulated firms depresses their stock prices and little if any evidence that this decline is the result of adverse information about future cash flows. Attempts to relate offer announcement effects directly to possible determinants of price elasticities, however, are inconclusive.

This paper examines the hypothesis that an important role of corporate takeovers is to discipline the top managers of poorly performing target firms. We document that the turnover rate for the top manager of target firms in tender offer‐takeovers significantly increases following completion of the takeover and that prior to the takeover these firms were significantly under‐performing other firms in their industry as well as other target firms which had no post‐takeover change in the top executive. We interpret the results to indicate that the takeover market plays an important role in controlling the nonvalue maximizing behavior of top corporate managers.
Event Risk: An Analysis of Losses to Bondholders and “Super Poison Put” Bond Covenants

Ten percent of the investment‐grade industrial bonds that were associated with major capital restructurings between 1983 and 1988 had already been downgraded to speculative grade as of August 1989. In response to these downgrades, and the corresponding wealth losses for bondholders, over 40 percent of recently issued investment‐grade industrial bonds are protected from this type of “event risk” by virtue of specialized covenants. These event‐risk convenants may have initially reduced interest costs for borrowers by roughly 20 to 30 basis points. However, the magnitude of the effect appears to have declined along with the general decline in corporate restructurings.
The Effects of Stock Repurchases on Rival Firms

This paper investigates the stock price behavior of rival firms in the same industry as firms announcing stock repurchase tender offers. Using a sample of 134 repurchase announcements, I find that rival firms on average realize insignificant announcement period abnormal returns. Negative rival stock price performance is detected over longer intervals surrounding the announcement period and for a subset of announcements which ex ante were identified as most likely to affect rivals. This evidence, however, is statistically weak and does little to alter the overall conclusion that the information in repurchase announcements is primarily firm‐specific.
Animal Spirits, Margin Requirements, and Stock Price Volatility

A simple overlapping generations model is used to characterize the effects of initial margin requirements on the volatility of risky asset prices. Investors are assumed to exhibit heterogeneous preferences for risk‐bearing, the distribution of which evolves stochastically across generations. This framework is used to show that imposing a binding initial margin requirement may either increase or decrease stock price volatility, depending upon the microeconomic structure behind fluctuations in economy‐wide average risk‐bearing propensity. The ambiguous effect on volatility similarly arises when the source of heterogeneity is noise trader beliefs.
Inferring Trade Direction from Intraday Data

CHARLES M. C. LEE, MARK J. READY
This paper evaluates alternative methods for classifying individual trades as market buy or market sell orders using intraday trade and quote data. We document two potential problems with quote‐based methods of trade classification: quotes may be recorded ahead of trades that triggered them, and trades inside the spread are not readily classifiable. These problems are analyzed in the context of the interaction between exchange floor agents. We then propose and test relatively simple procedures for improving trade classifications.
The Reversal of Large Stock‐Price Decreases

Extremely large negative 10‐day rates of return are followed on average by larger‐than‐expected positive rates of return over following days. This price adjustment lasts approximately 2 days and is observed in a sample of firms that is largely devoid of methodological problems that might explain the reversal phenomenon. While perhaps not representing abnormal profit opportunities, these reversals present a puzzle as to the length of the price adjustment period. Such a slow recovery is inconsistent with the notion that market prices quickly reflect relevant information.

This study examines the unit (stock) price and volume behavior of master limited partnerships (MLP) around the ex‐dividend day. Since the dividends of MLPs are not taxable to the unitholder, tax based hypotheses predict no abnormal unit movements around the ex‐day. Significant positive excess returns and volume are found before the ex‐dividend day, and significant negative excess returns are found on the ex‐dividend day. The findings which are not significantly impacted by the Tax Reform Act of 1986 suggest ex‐day stock movements are not solely a function of investor marginal tax rates or corporate trading behavior.
A Variance‐Ratio Test of Random Walks in Foreign Exchange Rates

CHRISTINA Y. LIU, JIA HE
The separate variance‐ratio tests under homoscedasticity and heteroscedasticity both provide evidence rejecting the random walk hypothesis, using five pairs of weekly nominal exchange rate series over the period from August 7, 1974 to March 29, 1989. The rejections cast doubt on the random walk hypothesis in exchange rates, which has received support in the existing literature. Furthermore, since the rejections are robust to heteroscedasticity, they suggest autocorelations of weekly increments in the nominal exchange rate series, which may be consistent with the exchange rate overshooting or undershooting phenomenon.
