Income tax burdens on family units are adjusted to reflect differences in ability to pay attributable to whether the unit consists of a single individual or a married couple and how many dependents are present. Substantial controversy exists over the appropriate forms of adjustment, and existing...

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...

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...

The conventional wisdom is that taxing individuals rather than households is superior from an efficiency point of view under progressive income taxation. This is because it leads to secondary workers, whose labour supply elasticity is high, being taxed at a lower marginal rate than primary...

The income tax system in the United Kingdom moved from joint to independent taxation of husbands' and wives' income in 1990. One interesting aspect of independent taxation is the ability for households to choose the division of household assets between the two spouses. This tax reform therefore...

Using longitudinal data on marriage and children from the Panel Study of Income Dynamics from 1967 to 2016, we characterize women's exposure to the federal and state Earned Income Tax Credit (EITC) during their first two decades of adulthood. We use measures of this exposure to estimate the...

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...

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...

Tax relief for child care expenses, encompassing the Child Care Tax Credit and Dependent Care Assistance Plans, is the largest federal government program in the United States aimed at helping families with child care. We examine the distributional effects of these policies among families with...

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....
