Panel surveys generally suffer from "seam bias"--too few transitions observed within reference periods and too many reported between interviews. Seam bias is likely to affect duration models severely since both the start date and the end date of a spell may be misreported. In this paper we...

In this chapter I provide a brief history of the TANF program, including changes made as part of the 2005 Deficit Reduction Act. I then present a variety of program statistics, including trends in aggregate and state-level caseloads and spending, along with changes in the demographic composition...

It has been long recognized that cash plays a critical role in fueling street crime due to its liquidity and transactional anonymity. In poor neighborhoods where street offenses are concentrated, a significant source of circulating cash stems from public assistance or welfare payments. In the...

This paper investigates the impact of changes in earnings disregards for welfare assistance received by single mothers following welfare reform in 1996. Some states adopted much higher earnings disregards (women could work full time and still receive welfare), while other states did not. We...

Using longitudinal data for 1968-2009 for male household heads, we determine the prevalence of pre- retirement age disability and its association with a wide range of outcomes, including earnings, income, and consumption. We then employ some of these quantities in the optimal social insurance...

We use an RCT to analyze the impacts of microcredit. The study population consists of loan applicants who were marginally rejected by an MFI in Bosnia. A random subset of these were offered a loan. We provide evidence of higher self-employment, increases in inventory, a reduction in the...

This paper measures the causal effect of time out of the labor force on subsequent employment of Social Security Disability Insurance (SSDI) applicants and distinguishes it from the discouragement effect of receiving disability benefits. Using a unique Social Security Administration workload...

In this paper, we exploit a cohort discontinuity in the stringency of the 1993 Dutch disability reforms to obtain causal estimates of the effects of decreased generosity of disability insurance (DI) on behavior of existing DI recipients. We find evidence of substantial "social support...
