The Computation of Opportunity Costs in Polychotomous Choice Models with Selectivity

Lung-Fei Lee

The Review of Economics and Statistics, 1995, vol. 77, issue 3, 423-35

Abstract: This article provides general formulas for the computation of opportunity costs (or foregone earnings) of chosen alternatives in sample selection models with polychotomous choices. With observed choice probabilities and outcomes of alternatives chosen by some individuals, the opportunity costs for individuals who do not choose those alternatives can be evaluated. For the probability indexed sample selection models with logit choice probabilities, which include the polychotomous choice model of Lung-fei Lee (1983), the formulas are simple and reveal restrictions implicitly imposed on those models. These formulas can be useful for empirical studies. Copyright 1995 by MIT Press.
