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.     

Initial Margin Requirements, Volatility, and the Individual Investor: Insights from Japan

Initial margin requirements represent: (1) a cost impediment to the wealth constrained investor and (2) a potential way of mitigating excessive volatility. However, prior empirical research finds that margins are not an effective tool in reducing volatility. We consider the possibility that margins primarily affect certain stocks and investors. Specifically, we test whether margins affect individuals who, as a group, we believe to be the investors most affected when margin requirements change. Our initial empirical tests, however, do not support this contention.

Remembering Mancur Olson

Mancur Olson, professor of Economics at the University of Maryland-College Park, died February 19, 1998. He served the Southern Economic Association as a member of the Executive Committee in 1978-80, as President-Elect in 1980-81, and as President in 1981-82. Three of his colleagues, Wallace Oates, Joe Oppenheimer, and Thomas Schelling, contributed personal essays to a memorial symposium in Public Choice Studies (No. 31, 1998), a journal published in Japanese. The Editor thanks the Japan Public Choice Society for permission to publish these contributions in English for the benefit of our readers.     

Intangible Assets and Firm Asset Risk Taking: An Analysis of Property and Liability Insurance Firms

Intangible assets facilitate insurers' capacity to retain existing business and attract new clients. In this study we analyze how the incentives to protect intangible assets affect asset risk-taking behavior of property and liability insurers. The result supports the view that insurers' incentives to protect their intangible assets lead to an inverse relation between intangible assets and asset risk. Consistent with the view that highly levered firms may go for broke, asset risk of highly levered insurers is less elastic to intangible assets than that of lower-levered insurers. An additional notable finding of our article is that tangible factors like firm size and capitalization increase insurers' appetites for asset risk taking.     

The economics of the thermohaline circulation—A problem with multiple thresholds of unknown locations

A potentially serious environmental threat facing humanity is the possibility of a collapse of the thermohaline circulation. Resulting climate changes, including absolute cooling near Greenland and northwest Europe, could be abrupt. Collapse of the thermohaline circulation may be triggered if the temperature or the rate of temperature change exceeds certain thresholds. The locations of these thresholds are unknown. Economic regulation of this problem requires solution methods for a class of dynamic optimization problems with multiple thresholds located in n-dimensional space. This class of problems has hitherto not been discussed in the literature. We present a model for the economic regulation of CO₂ emissions in the presence of threshold-triggered risk of a collapsing thermohaline circulation and derive optimality conditions for regulation.
