How Income Changes During Unemployment: Evidence from Tax Return Data

We use a panel of tax returns spanning 1999 to 2011 to provide evidence on household experiences during unemployment. A period of unemployment is associated with a 20 percent reduction in annual household wage earnings. Unemployment insurance (U.I.) compensates for half of lost wages. Households also partially compensate using a variety of income sources. Distributions from retirement accounts increase in the short run. Self-employment income and disability insurance payments increase over longer periods. More generous U.I. benefits crowd out wage income and are associated with increased retirement account distributions. This combination of responses is consistent with U.I. benefits lengthening unemployment spells.

Income Effects in Labor Supply: Evidence from Child-Related Tax Benefits

A parent whose child is born in December can claim child-related tax benefits when she files her tax return a few months later. Parents of children born in January must wait more than a year before they can receive child-related tax benefits. As a result, families with December births have higher after-tax income in the first year of a childs life than otherwise similar families with January births. This paper estimates the corresponding income effect on maternal labor supply, testing whether mothers who give birth in December work and earn less in the months following birth. We use data from the American Community Survey, the Survey of Income and Program Participation, and the 2000 Decennial Census. We find that December mothers have a lower probability of working, particularly in the third month after a childs birth. Earnings data from the SIPP indicate that an additional dollar of child-related tax benefits reduces annual maternal earnings in the year following a childs birth by approximately one dollar.
