By 1989 the Michigan Panel Study on Income Dynamics (PSID) had experienced approximately 50 percent sample loss from cumulative attrition from its initial 1968 membership. We study the effect of this attrition on the unconditional distributions of several socioeconomic variables and on the...

We estimate the trend in the transitory variance of male earnings in the U.S. using the Michigan Panel Study of Income Dynamics from 1970 to 2004. Using both an error components model as well as simpler but only approximate methods, we find that the transitory variance started to increase in the...

Nominal wage stickiness is an important component of recent medium-scale structural macroeconomic models, but to date there has been little microeconomic evidence supporting the assumption of sluggish nominal wage adjustment. We present evidence on the frequency of nominal wage adjustment using...

The decline in the employment-population ratios for men and women over the period 2000-2007 prior to the Great Recession represents an historic turnaround in the evolution of U.S. employment. The decline is disproportionately concentrated among the less educated and younger groups within the...

Although there is a large literature on the effect of AFDC and Food Stamps on labor supply and welfare participation, there has been little work on the effects of Medicaid, despite its importance in the O.S. transfer system. In this paper we use 1986 data from the Survey of Income and Program...

We present a model in which workers' aspirations for wage increases adjust slowly to shifts in productivity growth. The model yields a Phillips curve with a new variable: the gap between productivity growth and an average of past wage growth. Empirically, this variable shows up strongly in the...

Welfare benefits in the U.S. have experienced a much-studied secular decline since the mid-1970s. We explore a new hypothesis for this decline related to the increase in wage inequality in the labor market and the decline of real wages at the bottom of the distribution: we posit that voters...

It is well-known that real benefits in the major cash transfer program in the U.S. -- the Aid to Families with Dependent Children (AFDC) program -- have fallen drastically over the past twenty years. State legislatures, which set AFDC benefit levels, have failed to increase nominal benefits to...

A long-standing issue in the literature on education is whether marginal returns to education fall as education rises. If the population differs in its rate of return, a closely related question is whether marginal returns to higher education fall as a greater fraction of the population enrolls....

We explore the interaction between two facts. The first is that income is variable; the second is that the tax and transfer system transforms before tax income into after tax income in highly non-linear ways. The effect is to penalize (and reward) income variability in a manner which is both...
