Immigrant workers will be evaluated by their ability to speak English as well as by their other skills. The empirical work in this article add resses the hypothesis that there is an economic cost to English langu age deficiency both in occupation-specific earnings and in (cross-sec tional) occupational mobility. This analysis suggests that it is cost ly to be deficient in English, but the cost is ethnically and occupat ionally specific. Hispanics have a higher cost for English language d eficiency than Asians at every skill level. Copyright 1988 by University of Chicago Press.

Incentive problems arise in the electric utilities industry as a consequence of the institutional and legal arrangements of the cost-plus pricing regime under which natural and statutory monopolies operate. In the United States, such monopolies operate under a cost recovery system that gives the firm a mechanism by which it can shift all or part of the cost of moral hazard risk to consumers, who then become the residual claimants (Sherman [1980]). In this setting, expense accruals have a more direct link to the firm's cash flows than is the case in unregulated industries. In particular, pricing a monopolist's output at cost-plus means that accruing expenses generates sales revenues for utilities. Consequently, agency cost can be included in the allowable cost passed on to consumers. The result is that the residual loss is shared between the consumers and shareholders with two competing consequences: (1) it would be in the best interest of shareholders to provide managers with incentives to shift all costs to the consumer; and, by the same token, (2) it would be in the consumers' interest to persuade regulators to challenge the cost assumptions underlying the firms' requests for revenue requirements.

This paper presents a test of the theory of rational option exercise. Exercise data from the market for options on Treasury bond futures are used to test the model of rational early exercise developed by Barone-Adesi and Whaley (1987) (BAW). The results show that the BAW model underestimates the futures price that will trigger exercise for calls and overestimates this price for puts. The exercise bias is observed to change across option maturities and the direction of the bias is consistent with the direction of the model-pricing bias observed by Whaley (1986).

A choice function is strictly rational whenever it can be rationalized by a preference relation in a manner such that alternatives in a choice set are strictly preferred to alternatives in the corresponding rejection set. We demonstrate an Extension Theorem which asserts that a preference relation strictly rationalizes the choice function if and only if the choice function satisfies the Weak Axiom of Revealed Preference and the preference relation is an extension of the revealed weak preference relation. Then we consider various applications to rational choice theory.

[This article investigates the structure on preferences required to derive Ross's arbitrage pricing theory (APT). It is shown that only ordinal preferences are required. In particular, the APT does not require that agents possess preferences representable as risk-averse expected utility functions. This characteristic of the APT is not shared by the standard equilibrium-based capital asset pricing models.]

We examine capital structure changes to investigate the impact of SFAS No. 13 on lessees. While this accounting standard essentially rearranged capital lease disclosures (from footnotes to the balance sheet), mandated capitalization substantially altered key accounting ratios. Our results document a systematic substitution from capital leases to operating leases and nonleases sources of financing. In addition, lessees appear to reduce book leverage by increasing equity and reducing conventional debt. The magnitudes of these responses are cross-sectionally related to preadoption levels of footnoted capital leases.
