This chapter considers nonunitary models of household behavior. These models suppose
explicitly that households consist of a number of different members with preferences that are …

We examine the channels through which a randomized early childhood intervention in
Colombia led to significant gains in cognitive and socio-emotional skills among a sample of …

We propose a novel statistic to test the rank of a matrix. The rank statistic overcomes
deficiencies of existing rank statistics, like: a Kronecker covariance matrix for the canonical …

We examine the contribution of human capital to economy-wide technological improvements
through the two channels of innovation and imitation. We develop a theoretical model …

Vectors and matrices are useful in representing multivariate numeric data, and they occur
naturally in working with linear equations or when expressing linear relationships among …

A widely held but untested assumption underlying macroeconomic analysis is that the
number of shocks driving economic fluctuations, q, is small. In this article we associate q with …

This paper studies a shape‐invariant Engel curve system with endogenous total
expenditure, in which the shape‐invariant specification involves a common shift parameter …

In this paper we study the sources of wage growth. We identify the contribution to such
growth of general, sector specific and firm specific human capital. Our results are …

Which and how many attributes are relevant for the sorting of agents in a matching market?
This paper addresses these questions by constructing indices of mutual attractiveness that …

We propose a generalized method of moments (GMM) Lagrange multiplier statistic, ie, the K
statistic, that uses a Jacobian estimator based on the continuous updating estimator that is …
