This paper investigates the relation between the form of compensation and the manager's decision horizon. It finds that while all-cash contracts induce managers to underinvest in the long term, all-stock contracts induce overinvestment in the long term. It shows that compensation contracts consisting of both cash and restricted stock can produce efficient investment, thereby providing a rationale for the existence of both cash and stock incentive schemes in executive compensation packages. This explains why the adoption of either type of incentive scheme results in a positive stock price reaction. In addition, the paper derives the following testable hypotheses: i) the proportion of the stock compensation is decreasing in the precision of the manager's ability and increasing in the precision of the firm's cash flows; ii) firms compensate their managers with proportionately more stock in profitable years and proportionately more cash in leaner years; and iii) the greater the growth opportunities, the higher the proportion of stock compensation.

This paper examines cash management bill announcements in an event study framework and finds that segmentation in the Treasury bill market is widespread and not limited to bills maturing across month-ends. Announcements of cash management bills, which represent unexpected additional supplies of outstanding Treasury bills, cause the yields on these bills to rise significantly relative to yields on adjacent maturity bills. This paper also finds, consistent with other studies, that segmentation is greater at the short end of the bill market.

This paper examines rational expectations in the Treasury bill market from 1961 to 1988 with a risk premium specified to be proportional to the volatility of excess returns using instrumental variables. From 1961 to 1972 and from 1972 to 1979, rational expectations cannot be rejected, and both the predictive power of the yield curve and the risk premium are highly significant. By contrast, with just a constant risk premium and with a risk premium proxied by moving averages of absolute interest rate changes, rational expectations are rejected for each subperiod, and the yield curve has significant predictive information only from 1972 to 1979.

In a world of asymmetric information in which only the insiders know the quality of the firm, it is claimed that debt, even if it is risky, is more advantageous than outside equity because issuance of debt is less attractive to inferior firms. The advantage to debt arises from the fact that it can keep unprofitable firms out of the market, thus improving the average quality of firms in the market. This advantage exists even if the firms cannot be perfectly sorted in the signaling equilibrium.

A procedure is developed for the valuation of options when there are two underlying state variables. The approach involves an extension of the lattice binomial approach developed by Cox, Ross, and Rubinstein to value options on a single asset. Details are given on how the jump probabilities and jump amplitudes may be obtained when there are two state variables. This procedure can be used to price any contingent claim whose payoff is a piece-wise linear function of two underlying state variables, provided these two variables have a bivariate lognormal distribution. The accuracy of the method is illustrated by valuing options on the maximum and minimum of two assets and comparing the results for cases in which an exact solution has been obtained for European options. One advantage of the lattice approach is that it handles the early exercise feature of American options. In addition, it should be possible to use this approach to value a number of financial instruments that have been created in recent years.

This paper argues that an aggregate preferred habitat for investors exists on (or about) the last day of the calendar month, due to standardizations in the nation's payments system resulting in a concentrated flow of funds on this date. Thus, equilibrium yield discounts are predicted for securities maturing on such dates. Empirical tests on monthly and daily Treasury bill data support the principal hypothesis, as well as several ancillary hypotheses. The results have implications for Treasury debt management, for the short-term cash and debt management practices of businesses and banks, and for the empirical estimation of daily, weekly, or monthly return premiums on risky securities.

The search for an economically sound procedure for estimating an appropriate rate of return on equity consistent with the Supreme Court's ruling in the Hope case [13] has led many economists, financial experts, and public service commissions to estimate the rate of return on equity with the capital asset pricing model (CAPM) (see [30], [19], and [21]). The popularity of the CAPM in regulatory proceedings was reported by Harrington [15] who, in a survey of public service commissions, found that 38 states were considering or had seen the CAPM used, two jurisdictions preferred the CAPM, Oregon required the CAPM, and South Carolina would require the CAPM in all future cases. Hence, given the popularity of the CAPM and the tremendous economic impact that outcomes of regulatory proceedings have on the financial well-being of both the regulated firm and the consumer, it is critical that if the CAPM is used in regulatory proceedings that it be applied in the best manner possible and that any limitations associated with the CAPM be recognized fully.

This paper develops an exact theoretical test of the presence or absence of a filter effect for a portfolio of securities and a general number of different filter sizes. It is a natural development from Praetz [8], which obtained exact expressions for the mean and variance of rates of return of the investment strategies under filter tests assuming the underlying stochastic process is a random walk. These expressions showed that expected returns from filter strategies are, in fact, less than the return from a buy-andhold alternative with which filter returns are usually compared.

This paper is an analytic treatment of the abandonment decision in capital investment analysis. It provides a methodology which has application in obtaining better estimates for project value and risk.
