This paper examines the distributional and behavioral effects of the Earned Income Tax Credit (EITC). We chart the growth of the program over time, and argue several expansions show that real responses to taxes are important. We use tax data to show the distribution of benefits by income and...

This paper analyzes the optimal income tax treatment of couples. Each couple is modelled as a single rational economic agent supplying labor along two dimensions: primary and secondary earnings. We consider fully general joint income tax systems. Separate taxation is never optimal if social...

Analyzing a homogenous household setting with endogenous fertility and endogenous labor supply, we demonstrate that moving from joint taxation to individual taxation and adapting child benefits so as to keep fertility constant entails a Pareto improvement. The change is associated with an...

Many households face large, high-frequency changes in income and have limited financial buffers to smooth their consumption through this income volatility. However, few studies have quantified spending responses to such timing shifts in income due to a lack of high-frequency spending data. We...

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 studies the design of couples' income taxation. Consumption and labor supply decisions within the couple are made by maximizing a weighted sum of the spouses' utilities; bargaining weights are given but specific to each couple. The information structure and labor supply decisions...

The subsidy provided by the earned income tax credit (EITC ) is of particular importance to individuals subjected to domestic abuse, given that such individuals are often impoverished, and the EITC can provide them with the financial resources necessary to improve, endure, or leave an abusive...
