When decomposing differences in average economic outcome between two groups of individuals, it is common practice to base the analysis on logarithms if the dependent variable is nonnegative. This paper argues that this approach raises a number of undesired statistical and conceptual issues...

This paper suggests a method of decomposing differences in inter-group probabilities from a logit model and shows how it can be related to similar decompositions derived from a Oaxaca-Blinder framework. In so doing, it offers a solution to a problem, embedded within the Oaxaca-Blinder...

Research on the schooling implications of fertility transitions often faces an aggregation problem: despite policy interest in macro-level outcomes, empirical studies usually focus on the micro-level effects of sibsize on schooling. This article proposes an aggregation framework for moving from...

This paper deals with the full discretization of quasistatic 3D Signorini problems with local Coulomb friction and a coefficient of friction which may depend on the solution. After a time discretization we obtain a system of static contact problems with Coulomb friction. Each of these problems...

The goal of this paper is to identify and quantify the contribution of a set of covariates in affecting levels and over time changes of happiness inequality. We make use of a recent methodology that allows decomposing the overall change in happiness inequality into composition and coefficient...
