This paper demonstrates two important results related to the estimation of a competing risks model under the proportional hazards assumption with grouped duration data, a model which has become the canonical model for the termination of mortgages with prepayment and default as two competing...

This paper proposes a semiparametric willingness to pay distribution and discusses several aspects of statistical inference with dichotomous choice contingent valuation data. We study likelihood-based estimation of the model parameters with and without controlling for unobserved heterogeneity,...

This paper studies the estimation of a semiparametric bivariate proportional hazard model from event time data under interval censoring. As a direct generalization of the bivariate exponential distribution of Marshall and Olkin, the model, on the one hand, controls for the effects of observed...

In this paper we study the configuration dynamics and the societal equilibrium selection of repeated lattice games. Each player plays games only with his immediate neighbors hence indirectly interacts with everyone else. A player may or may not have perfect control over his action. Different...

This paper studies a structural model of labor market history in an environment with duration dependence. We treat the agent's job search effort explicitly as part of the dynamic decision along with a binary employment choice. The optimal policy is shown to exist and to be of the stationary...

The most popular survey method used in contingent valuations asks "open-ended" dichotomous choice questions. This method generates grouped or interval-censored data on respondents' willingness to pay. This paper specifies the willingness to pay distribution using the proportional hazard...

The allocation of resources between agriculture and non- agriculture is a central decision of a farm household. In this paper we formulate a profit-maximization model in which human capital enhances efficiency through both within-sector effects and across-sector allocation of quasi-fixed inputs....
