Many empirical studies specify outcomes as a linear function of endogenous regressors when conducting instrumental variable (IV) estimation. We show that tests for treatment effects, selection bias, and treatment effect heterogeneity are biased if the true relationship is non-linear. These...

Strong intergenerational correlations in various types of welfare use have fueled a long-standing debate over whether welfare receipt in one generation causes welfare participation in the next generation. Some claim a causal relationship in welfare receipt across generations has created a...

What do labor income dynamics look like over the life-cycle? What is the relative importance of persistent shocks, transitory shocks and heterogeneous profiles? To what extent do taxes, transfers and the family attenuate these various factors in the evolution of life-cycle inequality? In this...

This paper reviews the literature on intergenerational mobility. While our review is centered around the large empirical literature on this topic, we also give a brief discussion of some of the relevant theory. We consider three strands of the empirical literature. First, we discuss how to...
