Return migration, human capital accumulation and the brain drain

In this paper we present a model that explains migrations as decisions that respond to where human capital can be acquired more efficiently, and where the return to human capital is highest. The basic framework is a dynamic Roy model in which a worker possesses two distinct skills that can be augmented by learning by doing. There are different implicit prices, in different countries and different rates of skill accumulation. Our analysis contributes to the literature on the selection of immigrants and return migrants by offering a richer framework that may help to accommodate selection of emigrants and return migrants that are not immediately compatible with the one-dimensional skill model. Our analysis also has implications for the debate on brain drain and brain gain. In the two skills model presented here, return migration can lead to a mitigation of the brain drain, or even the creation of a “brain gain”, where those who return bring the home country augmented local skills.     

Dynamic Influences on Individual Choice Behavior

Research examining the process of individual decision making over time isbriefly reviewed. We focus on two major areas of work in choice dynamics:research that has examined how current choices are influenced by the historyof previous choices, and newer work examining how choices may be made toexploit expectations about options available in the future. A central themeof the survey is that if a general understanding of choice dynamics is toemerge, it will come through the development of boundedly-rational models ofdynamic problem solving that lie on the interface between economics andpsychology.     

You can pick your friends,and you can pick your nodes,but you can't pick your friends' nodes: misattributions of others'

One hundred and eleven managers from international organizations in Hungary selected success factors listed on cards by importance. The expressed preferences of non-Hungarians in this node selection task differed from the preferences attributed to them by the locals; the locals felt that the non-Hungarians did not care enough about the local environment, while the non-Hungarians - by their card selection - appeared to care more than the locals did about those issues. Several candidate explanations for the discrepancy are discussed, but all are eliminated with the exception of misattribution on the part of the locals. Implications of wide-spread misattribution, both for practice and for how management scholars go about their business, are discussed.     

The Effects of the Corporate Average Fuel Efficiency Standards in the US

This paper examines the effects of the Corporate Average Fuel Economy Standards (CAFE) on automobile sales, prices, and fuel consumption. First a discrete choice model of automobile demand and a continuous model of vehicle utilization are estimated using micro data from the Consumer Expenditure Survey for 1984–1990. Next, the demand side model is combined with a model of oligopoly and product differentiation on the supply side. With these elements in place, the effects of the CAFE regulation are assessed through simulations, and compared to the effects of alternative policy instruments, such as an increase in gasoline tax.     

Hedging exchange rate risk: The multiperiod case

We analyse production and hedging in a multiperiod framework for a risk-averse exporting firm facing a random exchange rate. We extend the separation theorem to this multiperiod model. Our study shows that unbiased currency forward markets in all periods do not imply standard full hedging. Under some conditions, the firm tends to overhedge compared to the one-period hedging models.     

Fetal protection: Law,ethics and corporate policy

Corporate fetal protection policies are designed to protect unborn children from exposure to harmful substances in the workplace. In recent years, a number of corporations have instituted fetal protection policies which excluded all fertile female employees from jobs which exposed them to hazardous substances. Critics argued that these policies discriminated against women, and several lawsuits were filed.The United States Supreme Court recently decided a case involving the fetal protection policy of Johnson Controls, Inc. This article will analyze the impact of the Supreme Court decision from a legal and ethical perspective. Practical guidelines for policies which protect the unborn and comply with the law will also be addressed.Ira Sprotzer, J.

The Association Between the Level of International Diversification and Risk

This study analyzes the association between the degree of international involvement (DOI) and risk. Both systematic risk (measured by the market model beta) and total risk (measured by variance of return) are analyzed. Betas of fully diversified foreign stock portfolios are shown to be lower than betas of domestic portfolios. Therefore, if the beta of a foreign investment by a U.S. firm is equal to the average beta of an investment in the foreign market, then overall firm beta will decrease as DOI increases (hypothesis). While total risk might be decreased due to the diversification provided by increasing DOI, currency, political, and other risks could cause total risk to increase. Briefly, the results of this study suggest that (1) systematic risk is negatively related to DOI even after controlling for other factors known to be associated with systematic risk, (2) intertemporal changes in systematic risk are negatively related to intertemporal changes in DOI, and (3) in contrast to the results of previous research, DOI is not negatively related to total risk and, in fact, intertemporal changes in total firm risk are marginally positively related to intertemporal changes in DOI.
Our results suggest that increasing DOI decreases systematic risk but increases total risk. Year to year changes in both beta and variance of return appear to be related to year to year changes in DOI. While currency, political, and other risks of international operations increase total risk, these risks apparently can be diversified away resulting in a beta that behaves as a blending of its previous level and the beta of a fully diversified investment in the foreign market.
