This paper analyzes the effects of a large randomized field experiment, carried out with H&R Block, offering matching incentives for IRA contributions at the time of tax preparation. About 15,000 H&R Block clients, in 60 offices in predominantly low- and middle-income neighborhoods in St. Louis,...

This paper analyzes a randomized experiment to shed light on the role of information and social interactions in employees・decisions to enroll in a Tax Deferred Account (TDA) retirement plan within a large university. The experiment encouraged a random sample of employees in a subset of...

This paper presents series on top shares of income and wealth in Spain using personal income and wealth tax return statistics. Top income shares are highest in the 1930s, fall sharply during the first decade of the Franco dictatorship, then remain stable and low till the 1980s, and have...

We construct a microfounded, dynamic version of the IS-LM-Phillips curve model by adding two elements to the money-in-the-utility-function model of Sidrauski (1967). First, real wealth enters the utility function. The resulting Euler equation describes consumption as a decreasing function of the...

In Project STAR, 11,571 students in Tennessee and their teachers were randomly assigned to classrooms within their schools from kindergarten to third grade. This article evaluates the long-term impacts of STAR by linking the experimental data to administrative records. We first demonstrate that...

We develop online survey experiments to analyze how information about inequality and taxes affects preferences for redistribution. Approximately 4,000 respondents were randomized into treatments providing interactive, customized information on U.S. income inequality, the link between top income...

We then analyze top income and top tax rate data in 18 OECD countries. There is a strong correlation between cuts in top tax rates and increases in top 1% income shares since 1975, implyingthat the overall elasticity is large. But top income share increases have not translated into higher...
