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...

We investigate an overlapping generations monetary economy in which agents'expectations depend upon backward looking predictors of the future price level.

The objective of this paper is to determine how finite dimensional parameters can be efficiently estimated for an important class of economic models.

We develop regression-based tests of hypotheses about out of sample prediction errors. Representative tests include ones for zero mean and zero correlation between a prediction error and a vector of predictors. The relevant environments are ones in which predictions depend on estimated...

We study a panel structure with n subjects/entities being observed over T periods. We consider a class of models for each subject's data generating precess, and allow the unknown heterogeneity. In other words, we do not know many types we have, what the types are, and which subjects belong to...

This paper provides a unified framework for interpreting a wide range of interactions models which have appreared in the economic literature. The framework bears a close relationship to econometric models of descrete choice and therefore holds the potential for rendering interactions models...

In this paper we present a method for solving the multifirm stochastic growth model of Brock (1979). After obtaining a solution to the growth model, we derive a solution to the asset pricing model of brock (1982) using the duality between the two models.

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...

In this paper we have presented a model in which perfectly enticipated inflation is superneutral: if the variance of the money (or the growth rate of the money supply in the dynamic interpretation) supply is zero, the real equilibrium is independent of the mean of the money supply.
