Extremum estimation is typically an ad hoc semi-parametric estimation procedure which is only justified on the basis of the asymptotic properties of the estimators. For a fixed finite data set, consider a large number of investigations using different extremum estimators to estimate the same...

The EC (Estimation-Classification) estimator, and its companion EC-algorithm, were introduced in El- Gamal and Grether (1995), and their properties further analyzed in El-Gamal and Grether (1996). The purpose of EC estimation is to uncover heterogeneity in panel data models in a manner which is...

An overlapping generations model of marriage and divorce is constructed to analyze family structure and intergenerational mobility. Agents differ by sex, marital status, and human capital. Single agents meet in a marriage market and decide whether to accept or reject proposals to wed. Married...

We applied a notion of minimal-monotonic extention to a variety of economic models and showed that the minimal monotonic extension of a number of solutions can be easily calculated.

We obtain semiparametric efficiency bounds for estimation of a location parameter in a time series model where the innovations are stationary and ergodic conditionally symmetric marginale differences but otherwise prossess general depence and distributions of unknown from. We then describe an...

We address the problem of allocating indivisible goods and some amount of an infinitely divisible good among agents with equal rights on these resources. Our specific objective is to investigate the implications of the following requirement on allocation rules : when the preferences of some of...

In allocation problems of perfectly divisible goods, we study the equity property of 'no-domination', according to which no agent can receive strictly more of all goods than any other agent. We prove that no-domination is incompatible with Pareto efficiency, as soon as preferences are allowed to...
