Empirical studies of the behavior of stock returns are important for several reasons. First, the nature of stock return behavior is fundamental to the formulation of the concept of “risk” (or “uncertainty”) in various financial theories and models. Second, the measurement of risk depends heavily on properties (such as the stationarity, long-tailedness, finiteness of the second and higher moments, etc.) of empirical stock return distributions. Third, various tests for the empirical validity of financial models [28] and the applications of these models (e.g., to the evaluation of investment performances [21], [22]) rely to a considerable extent on the steadiness over time of stock return distributions and the constancy of systematic risk. Fourth, several important pricing models for stock options, warrants, convertible debentures, and other similar financial instruments usually require explicit estimates of stock return variances [5]; the usefulness of such models depends largely on the adequacy (e.g., the finiteness, accuracy, etc.) and the stationarity of the variance measurements.

The Jaffee and Russell [1976] model of credit rationing under imperfect information and uncertainty suggests that a single-contract equilibrium will tend to occur at a point of rationing and that a multiple-contract equilibrium will likely be unstable. This paper respecifies and extends the Jaffee-Russell model to incorporate default expectations on the demand side and to consider the price of credit more appropriately to be the net (after expected default) yield rather than the contract rate. Results show rationing is not necessary in the single-contract equilibrium case, nor is an unstable equilibrium possible in the multiple-contract case.

There is a natural separation between production decisions affecting the firm as a whole and individual decisions by each shareholder about his portfolio of securities. The end result of these two types of decisions is normally referred to as a productive exchange equilibrium. At such an equilibrium, no individual wants to adjust his portfolio and no firm can muster majority support for a change in its production plans. This paper presents a partial theory of takeover bids in that it examines the role of a takeover bid as a mechanism by which a simultaneous change in shareholdings and production plans can be achieved. This enables a new production exchange equilibrium to be reached which is preferred by a majority of the shareholders but which is inaccessible without a contingent contract in the form of a takeover bid.

This study analyzes the residential and commercial demand for electricity in ten regions in Paraguay for 1970-1977. Models that are both linear and nonlinear in the parameters are estimated. The nonlinear model takes advantage of prior information on the nature of the appliances being utilized and simultaneously deals with the demand discontinuities caused by appliance indivisibility. Three dynamic equations, including a novel cumulative adjustment model, all indicate rapid adjustment to desired appliance stock levels. Finally, the multiproduct surplus loss obtained from an estimated demand equation is used to measure the welfare cost of power outages. 15 references.

A contingent claims valuation model is used to estimate the values of a sample of convertible bonds and to partition those values into their debt and equity portions. The model and market values of the bonds are compared and model estimates are found to be approximately unbiased relative to market values, with about 90 percent of the values within ten percent Of market values. The average equity values of the convertible bonds are found to constitute 16.7 percent and 18.4 percent of the book and market values of the bonds, respectively. When leverage and dilution measures for the sample are restated by excluding the estimated equity value of convertibles from debt, differences are small on average, but for some firms they are substantial. A comparison of reported earnings per share (EPS) with EPS using model equity values reveals that model EPS differs cross-sectionally from both primary and fully diluted EPS but is much closer on average to primary EPS. The findings of the study provide reason for optimism regarding applications of contingent claims models to practical valuation problems, particularly with regard to more meaningful measures of dilution of earnings and leverage.
