Over the period 1960 - 1983 the proportion of federal tax revenue raised by taxation of labor supply has risen from 57-77 percent. In this paper, we specify and estimate a model of family labor supply which treats both federal and state taxation. Husbands and wives labor supply are treated...

Currently U.S. Federal Income Tax schedules do not maintain marriage neutrality, that is, tax liabilities depend upon marital status. This paper shows the extent and distribution of the departure from neutrality both under current law and the new (1981) tax act. The new tax law establishes a...

A number of suggestions have been made to reform the tax treatment of the family. None of these proposals has been accompanied by careful estimates of their effects on the income distribution, revenue collections, and labor supply. The purpose of this paper is to provide such information. Our...

This paper examines the appropriate tax treatment of the family in a series of analytical models and numerical examples. For a population of taxpaying couples which differ in earning capacity, we derive the optimal tax rates for each potential earner. These rates depend crucially upon own and...

In recent years, many states and some local governments implemented or expanded their own supplemental Earned Income Tax Credits (EITCs). The expansion of state EITCs may have stemmed in large part from wanting to provide a more generous program than the federal program, because state EITCs...

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...

In 2002 more than 18 million low-income individual taxpayers received the Earned Income Tax Credit (EITC). Despite its size, non-participation in this program is a concern and substantial effort is devoted by the IRS, local governments and many non-profits to address it. Most of the tax returns...

We examine the labor market consequences of the Earned Income Tax Credit (EITC), comparing labor market behavior of eligible parents in Wisconsin, which supplements the federal EITC for families with three children, to that of similar parents in states that do not supplement the federal EITC....

Marriage penalties are a controversial feature of many government policies. Empirical evidence of their behavioral effects is quite mixed. This is surprising because economic theory predicts that they should have an impact on the headship decision. We investigate the removal of marriage...
