This paper considers forecast averaging when the same model is used but estimation is carried out over different estimation windows. It develops theoretical results for random walks when their drift and/or volatility are subject to one or more structural breaks. It is shown that compared to...

This paper introduces a novel approach for dealing with the 'curse of dimensionality' in the case of large linear dynamic systems. Restrictions on the coefficients of an unrestricted VAR are proposed that are binding only in a limit as the number of endogenous variables tends to infinity. It is...

An influential explanation for the recent rise in the U.S. current account deficit is the boom in U.S. productivity. As U.S. productivity surged, capital was attracted to the U.S. to take advantage of the higher real returns. Using a two country general equilibrium model, this paper...

In this paper we study the effect of reallocating an indivisible input across a population of production units on average output. We define the Average Redistributive Effect (ARE) as the effect of such a reallocation on average output. We consider the case where inputs are discretely-valued,...

We show that in the nonparametric triangular simultaneous equations model, the mean independence conditional moment restriction (CMR) identifies a causal relation between the dependent variable and an endogenous covariate, only if the model is structurally separable in observable covariates and...

Economists have devoted substantial resources to estimating the intertemporal substitution elasticity for labor supply because this elasticity plays a crucial role in the real business cycle literature. Generally, the estimates of the elasticity have been too low to explain business cycles....
