THE MORISHIMA ELASTICITY OF SUBSTITUTION FOR THE VARIABLE PROFIT FUNCTION AND THE DEMAND FOR IMPORTS IN THE UNITED STATES*

In this article, I derive expressions for the Morishima elasticities of substitution (MES) for the variable profit function and estimate these elasticities to shed some light on the substitutability between imports, capital services, and labor services. The results reveal that capital services and imports are Morishima substitutes, irrespective of whether the price of capital services or imports changes, and imports and labor services are also Morishima substitutes, irrespective of whether the price of imports or the wage rate changes. Thus, an increase in the price of U.S. imports (through tariffs or duties) will result in substitution (in the Morishima sense) into labor and capital services.     

Liquidity, Labels and Medium-Term Notes

We suggest that the medium-term note market provides an excellent laboratory for exploring the relationships between yield, liquidity, and the label affixed to a financial instrument. Crabbe and Turner (1995) examined the liquidity issue and uncovered the counter-intuitive result that issue size is unrelated to liquidity. Their study failed to examine a potential channel for a liquidity effect, however, in the form of multiple issues from a single, typically large, MTN registration filing. We find evidence that file size is significantly related to yield in a number of instances. Several other proxies for liquidity, such as frequency of issue, are also sometimes significantly related to yields. Contrary to Crabbe and Turner (1995) , we find that labeling a security an MTN can have an impact on its yield. The label "note" also appears to matter for yield in some instances.     

Long- and short-term interest rates in 19 countries: Tests of cointegration and parameter instability

This paper examines the long-run relationship between short-term and long-term interest rates (both nominal and real) in 19 countries, and explores the possibility that the relationship is statistically stable using Lc, MeanF, and SupF statistics suggested by Hansen [1992]. Empirical results obtained from various cointegration techniques (Johansen, Phillips and Hansen, Stock and Watson, and Park) and quarterly data (1973–1998) show considerable support for the expectations hypothesis in all countries (except the United Kingdom). In a majority of cases, it is also found that a stable relationship exists between the short-term and long-term interest rates.     

Endogenous Group Formation

While the rules governing the formation of groups engaging in collective action may have significant impact on group size and behavior of members, most experiments on public goods have been conducted with the subjects in exogenously fixed groups or of fixed sizes. We study endogenous formation of groups in a public‐goods provision game by allowing subjects to change groups under three sets of rules: free entry/exit, restricted entry with free exit, and free entry with restricted exit. We find that the rules governing entry and exit do have a significant impact on individual behavior and group‐level outcomes.     

NONPROFIT EMPLOYEES' MACHIAVELLIAN PROPENSITIES

Nonprofit organizations are held to high ethical standards due to their charitable missions serving the common good. Incidents of fiscal mismanagement within the nonprofit sector make it relevant to assay the ethical principles of employees. This study examines the level of Machiavellian propensities of US nonprofit employees. Results indicate Machiavellian propensities do exist in certain nonprofit employees and these employees agree with questionable behavior. Policy makers and oversight agencies may find these results useful in developing corporate governance and accountability measures for nonprofit organizations. Furthermore, board of director members may use these results to monitor employee actions and address management training.     

Free Agency and the Allocation of Labor in Major League Baseball

In this paper we examine the allocation of labor under free agency by developing and testing a model to predict the migration of free agents. Data for individual players are used in a logit model that estimates the probability that a free agent will change teams as a function of several independent variables. Along with other authors, we find that free agents tend to migrate to big cities. In addition, we find evidence that the allocation of labor may be different under free agency than under the reserve clause and suggest a reason why Coase's theorem may not be applicable to this labor market.     

Effects of adjustment of the green drachma to its current exchange rate

Between 1981 and 1988, the drachma has devalued by 62.5% against the ECU. Until mid-1985 any devaluation of the drachma was followed by a corresponding devaluation of the ‘green drachma‘. After that period, the green rate either remained unchanged or changed by a substantially smaller percentage, resulting in farmers' income loss and consumers' gain. The aim of this paper is to investigate the welfare effects on production/producer, consumption/consumer and budgetary flows from and to FEOGA assuming that an adjustment of the green drachma to its current exchange rate was realized. For this purpose partial analysis methodology is employed. The main findings are that, following a simultaneous adjustment of both rates, the gains to producers and in exchange flows more than make up for the corresponding consumers' losses for all products except beef.
