Differential taxation and the equilibrium structure of interest rates

Equilibrium coupon bond pricing relationships given differential taxation are derived under uncertainty assuming that both corporate and municipal bonds were originally issued at par but are currently selling at a discount. The impact of differential taxation upon the term structure and coupon structure of interest rates is investigated, while the tax structure of interest rates is uniquely characterized. Differential taxation substantially alters the prevailing equilibrium structure of interest rates.     

The demand for money during a period of inflationary expectations. Some FIML based estimates for Greece

This paper estimates and tests a model of the demand for money function, which uses the public's expectations of future inflation as a proxy of the opportunity cost of holding money. The hallmark of the paper is that expectations are rational inMuth sense. The cross-equation rational expectations restrictions are derived and then tested, using quarterly Greek data of the high inflation period 1973I to 1981 IV. The paper concludes that the evidence is consistent with the rational expectations assumption and supports the adopted specification of the money demand function.     

On inferring standard deviations from path dependent options

Path dependent option prices are employed to derive implied standard deviations of the underlying security price process without recourse to numerical procedures. We empirically illustrate our methodology by inferring the volatility of gold prices.     

The effect of ESOP adoptions on corporate performance: are there really performance changes?

Employee Stock Ownership Programs (ESOPs) have long been promoted as a motivational tool: employees become profit‐minded owners. Latterly, however, more ESOPs are being used as part of a takeover defense: here the ESOPs main purpose is to put more company stock in friendly hands—the employees—who, like existing management, could suffer layoffs, etc. in a hostile takeover. We find that, as a group, only the takeover‐related ESOPs are associated with increased leverage (itself a takeover defense). Non‐target firms show no long‐term increase in debt‐to‐assets. We find little evidence to support the motivation hypothesis: while actual labor costs are lower for ESOP firms, after industry‐adjusting they tend to be unaffected or higher. We find that a few measures of firm financial performance [return‐on‐equity (ROE), return‐on‐assets (ROA), net profit margin (NPM)] do improve significantly, but this appears to be largely a short‐term effect. Industry‐adjusted holding period returns appear to be unaffected by the ESOP; however, ESOP firms that leverage show evidence of long‐term market underperformance. We conclude that ESOPs provide, at best, only a short‐term boost to corporate performance. Copyright © 2000 John Wiley & Sons, Ltd.     

Joint research and development projects as technology training ventures

This paper presents an empirically derived model of the process through which industrial firms that lack internal resources in a particular technology area to implement certain research and development (R&D) projects on their own, initiale nad implement them jointly with not-for-profit research institutions. Such joint R&D projects are typically initiated by smaller, technologically less advanced firms in developing countires, with the underlying objective of training themselves in the relevant technology area and acquiring new technological resources from more advanced local research institutions, while simultaneously and rapidly completing the immediate R&D project. This process model has been developed by drawing from and synthesizing several in-depth case studies of such projects. In developing countries, joint R&D projects of this nature are important, as they can be more effective than formal technology training programmes for not-for-profit research institutions to fulfil their charter by transerning their advanced technical knowledge to the relatively less advanced local industrial firms. Participating firms that seek to their immediate interest, and therefore learn it rapidly and effectively. This paper adds to the scarce literature on ht process of organizational knowledge acquisition through contractual arrangements such as joint projects. It also enables both firms and research institutions to understand effective proceses for initiating and implementing such mutually beneficial joint R&D projects.     

Comparing Student Achievement across Experimental and Lecture-Oriented Sections of a Principles of Microeconomics Course

An increasingly popular alternative to the lecture-oriented “chalk-and-talk” approach to teaching principles of microeconomics is the use of classroom experiments. Like other alternatives to traditional teaching methods, there exists little more than anecdotal evidence supporting the effectiveness of the experimental approach. We estimate the effect of participating in classroom experiments on student achievement in a principles of microeconomics course. Nine sections (300 students) participated in the study, two of which (59 students) relied heavily on classroom experiments throughout the semester. The remaining seven sections (241 students) used no experiments. We find that students in the experimental sections experienced significantly higher gains in Test of Understanding in College Economics (TUCE) scores but differed little on other more qualitative outcomes. Additionally, results indicate that certain student characteristics, including gentler, major, and grade point average, can be used to predict a student's likely success when choosing between courses that rely on experiments and those that employ more traditional forms of pedagogy.
