Economic Growth With Intergenerational Altruism

(with Doug Bernheim), Review of Economic Studies 54, 227-243, 1987.

Summary. We consider the properties of equilibrium behavior in an aggregative growth model with intergenerational altruism. Various positive properties such as the cyclicity of equilibrium programs, and the convergence of equilibrium stocks to a steady state, are analyzed. Among other normative properties, it is established that under certain natural conditions, Nash equilibrium programs are efficient and “modified Pareto optimal”, in a sense made clear in the paper, but never Pareto optimal in the traditional sense.

Nit-Piketty

CesIfo Economic Studies 2015.

Summary. Yes, capital must displace labor, but not because r > g. This article is based on this blog post, Branko Milanovic objected here; I replied. Piketty replies to some of his critics here.

 

A Theory of Occupational Choice with Endogenous Fertility

(with Dilip Mookherjee and Silvia Prina), American Economic Journal: Microeconomics  4, 1–34, 2012.

Summary. Theories based on partial equilibrium reasoning alone cannot explain the widespread negative cross-sectional correlation between parental wages and fertility, without restrictive assumptions on preferences and childcare costs. We argue that incorporating a dynamic general equilibrium analysis of returns to human capital can help explain observed empirical patterns.
