ACTIVITY SELECTION UNDER CONDITIONS OF RISK AND INSTABILITY: CONSIDERATION OF FREQUENCY

The terms ‘instability’ and ‘risk’ are sometimes used interchangeably in the literature. Some make the argument that instability will shift the firm's supply curve to the left if the producer is risk-averse Risk, however, is associated with the unpredictable residuals, or deviations from the producer's revenue expectations. The inherent instability of these returns does not necessarily imply an added exposure to risk as long as the producer forms his expectations based on the entire information set available to him when constructing the mathematical model representing his judgement on the variables' future behaviour. The producer may also respond to the relative instability of the returns generated by an enterprise even if risk, as defined above, is perceived to be non-existent. The existence of prediction errors exposes the producer to conditions of choice under risk while the predictable component exposes the producer to conditions of choice under instability. His preferences with regard to risk and instability may be quite different. The purpose of this paper is to extend the traditional planning model under risk to account for the producer's attitude toward the predicted instability of returns over time, and to illustrate the effect that this attitude will have upon his production plans.     

Alternative utility functions: review,analysis and comparison

The paper reviews the development of von Neumann and Morgenstern (vNM) utility theory. Kahneman and Tversky’s (KT’s) prospect theory is introduced. The vNM utility function is compared and contrasted with KT’s value function. We prove the uniqueness of two popular utility functions. First, we show that all power utility functions possess constant RRA. And, we show that all exponential utility functions have constant ARA. The paper concludes by discussing applications, strengths and weaknesses of various utility functions.     

Project Valuation With Time-Varying Cash Flows: A Bayesian Approach

This article investigates the valuation of a project when the distributions of cash flows vary over time. The decision maker is assumed to be a Bayesian decision maker under uncertainty. Using the dynamic programming principle of backward induction and assuming that the capital asset pricing model is valid in each time period, we derive the project's valuation formulas and systematic risks, and investigate their characteristics. Our valuation formulas embed a Bayesian learning effect and differ from the traditional textbook capital budgeting formulas.     

The meaning of work,employment relations,and strategic human resources management in Israel

The paper deals with the meaning of work, employment relations, and strategic human resources management. First it shows that Israeli workers have become more individualistic and materialistic, and less collectively oriented, as instrumental achievements outweigh contributions to society. These issues apparently influence employment relations and organizational policies. Next, it deals with the corporatist employment relations system, based on tri-partite collective bargaining among employees, employers, and the state. During various times, the relative balance of power among the three parties swayed considerably, according to major political, economic and social events taking place in society. The final section on strategic human resources management focuses on the transition of Israel's Human Resources profession, from the traditional HR role to the new Strategic Human Resource Management role. These three spheres have gone through some significant changes in the last several decades, perhaps not parallel to most industrial nations.     

AUDITOR CHOICE AND AUDIT FEE DETERMINANTS

An analytical model predicts that cross-sectionally (1) the marginal cost of auditor quality is inversely related to the strength of client companies' internal control. (2) In the short run, clients with stronger control, lower business risk, or less complex audits choose higher quality auditors; but whether they pay higher audit fees is indeterminate. (3) In the long run, client companies have both lower quality auditors and weaker controls as risk or complexity increase, so less precise financial reporting is expected from them. (4) The effects of risk and complexity on fees are indeterminate, because the price and quantity components of fees tend to vary inversely as risk or complexity change. The predictions are consistent with findings that have been viewed as empirical anomalies.     

Pricing futures on geometric indexes: A discrete time approach

Several futures contracts are written against an underlying asset that is a geometric, rather than arithmetic, index. These contracts include: the US Dollar Index futures, the CRB-17 futures, and the Value Line geometric index futures. Due to the geometric averaging, the standard cost-of-carry futures pricing formula is improper for pricing these futures contracts. We assume that asset prices are lognormally distributed, and capital markets are complete. Using the concepts of equivalent martingale measure and the risk-neutral valuation relationships in conjunction with discrete time methodology, we derive closed-form pricing formulas for these contracts. Our pricing formulas are consistent with the ones obtained via a continuous time paradigm.
