Do Taxes Matter? is the first systematic examination of the actual effects of the Tax Reform Act of 1986, the most important U.S. income tax reform of the last four decades. It presents basic information on and an analysis of a variety of different aspects of economic behavior in order to discover whether the observed changes coincide with the predictions of standard public finance models. Prior to implementation of the new law, supporters and opponents made numerous forecasts about its effect on savings, corporate investment, and other major determinants of the country's economic health. The general finding of these original contributions is that the effects of tax reform turned out to be smaller than had been anticipated. Commissioned by the Office of Tax Policy Research of the University of Michigan, eight of the studies focus on different sectors of the economy, reviewing the predictions and carefully analyzing the evidence to determine actual effects. The ninth study draws together the results to find lessons for future changes in tax policy. Joel Slemrod is Professor of Business Economics and Public Policy and Director of the Office of Tax Policy Research at the University of Michigan.
