This paper presents a model of equilibrium in a capital market for linear shares of risky firms andin a market for managerial labor in which market participants function as both investors and managers. The model yields interesting and relevant equilibrium conditions that integrate earlier separate treatments of the capital market with human capital and the incentive contracting problem regarding shirking.The theory developed here provides a microeconomic explanation of how the price of risk established in the capital market is relevant to the labor contracting problem. The analysis also provides a logical rationale for the division of responsibilities between a board of directors and the management of the firm.

The quadratic form of the covariance-co-skewness model by Kraus and Litzenberger and arbitrage pricing theory are used for an empirical investigation of market equilibrium with skewed seecurity returns. Empirical tests similar to the ones in Black-Jensen-Scholes and Gibbons are discussed. The empirical estimates give some support to the Kraus-Litzenberger hypothesis on skewness preference. However, there is some evidence that the tested arbitrage equilibrium is not a complete description of security pricing.

This paper considers two aspects of the tendency for systematic risk to change during the period surrounding a firm-specific event. First, a statistic allowing for heteroskedasticity is presented as a means of more precisely testing for the incidence of structural change in the market model. Secondly, the bias resulting from the imposition of a single, arbitrary event period on every firm in a market efficiency study is formally demonstrated. Using a sample based upon stock splits, the switching regression technique of Quandt is then adapted to show that event intervals are more appropriately considered on a case-by-case basis. A comparison of alternative residual measures illustrates these procedures.

Daily cash forecasting generally requires some method to reflect day-of-month and day-of-week effects. It requires the resolution of multiple seasonals, a problem given scant treatment in the econometrics literature. This paper first presents multiplticative and mixed-effects specifications of day-of-month and day-of-week effects as alternatives to the additive specifications. Then, several important estimation issues pertinent to each specification are investigated, namely collinearity, holiday effects, length-of-month distortion, varying weekly-monthly pattern mix, and daily-monthly consistency.

The paper develops a broad class of distribution-based linear forecasting models in great generality similar to the way that Box and Jenkins [1] provide a broad class of time-series models that can be specialized via parameter selection (specification). In our case, parameter selection (specification) gives particular members of the linear class of distribution models. A particular version can be tested against an alternative specification via hypothesis tests on model parameters.

This paper treats a problem of stochastic cash management under an average compensating-balance requirement. It develops a dynamic programming formulation of the problem in which the relevant state is a unidimensional quantity equivalent to the forecasted average balance at the end of the averaging period. Under usably broad conditions, it establishes the optimality of a transient policy of simple type, similar to the two-sided inventory type policy familiar from certain earlier studies of stationary cash balance problems having absolute balance requirements. The results apply to cases in which the transactions costs contain both fixed and proportional components. The paper discusses also a numerical example drawn from the literature of the cash balance problem and shows by simulation of the optimal (and simply modified forms of the optimal) policy, that good protection is afforded against negative balances, even though the model does not explicitly constrain the negative-balance probabilities.

This paper is concerned with the effect of futures trading in Treasury bills on the volatility of yields in the cash market. It is found that futures trading led to a decrease in volatility initially, but the effect disappeared when futures volume became large and possibly resulted in increased volatility in the secondary cash market. The results also indicated that the deliverable bill appears to sell at a small premium relative to the adjacent maturities prior to the delivery date.

A necessary and sufficient condition for linear sharing rules to be Pareto optimal, as generally accepted by the finance community, is that utility functions be of the equicautious HARA class. We demonstrate that this condition is not necessary for a fixed distribution of initial endowments and derive the necessary and sufficient condition. We show examples of utility functions satisfying our conditions.

In this note, a loss shared by the security holders of merging firms is pointed out: separate corporate entities provide double protection against future negative cash flows that are partof any production process (e.g., when customer or employee liabilities exceed future income), independent of whether or not debt is used in the corporate capital structure. A merger involvesa relinquishment of this double protection in return for a less valuable single protection: limited liability in the merged corporation against combined negative cash flows.
