Economists have studied the impact of numerous state laws, from welfare rules to voting ID requirements. Yet for all this policy evaluation, what do we know about policy diffusion--how these policies spread from state to state? We present a series of facts based on a data set of over 700 U.S....

Fiscal policy in the U.S. and other countries renders intertemporal budgets non-differentiable, nonconvex, and discontinuous. Consequently, assessing work and saving responses to policy requires global optimization. This paper develops the Global Life-Cycle Optimizer (GLO), a stochastic...

We show that the largest increase in unemployment benefits in U.S. history had large spending impacts and small job-finding impacts. This finding has three implications. First, increased benefits were important for explaining aggregate spending dynamics--but not employment dynamics--during the...

I discuss recent books offering differing explanations for persistent U.S. poverty. Desmond (2023) argues that aid to low-income Americans is captured by more powerful market actors. I contextualize this concern as about incidence and consider both policies for changing incidence (by changing...

How has the internet affected search and hiring, and what are the implications for aggregate unemployment? Answering these questions empirically has proven difficult due to selection in internet use and difficulty in measuring the search activities of both sides of the labor market. This paper...

Take-up of a social benefit is usually defined as receiving a benefit for which an individual or household is eligible. The take-up rate is the fraction of those eligible for a program who participate and receive a benefit or service. We survey estimates of take-up of social benefits around the...

Stigma of welfare participation is important for policy and survey design, because it deters program take-up and increases misreporting. Stigma is also relevant to the literature on social image concerns, yet empirical evidence is scant because stigma is difficult to empirically identify. We use...

We are the first to document that Supplemental Nutrition Assistance Program (SNAP) caseworker behavior impacts program receipt, likely due to differing levels of helpfulness in navigating the complicated application process. We use the conditional random assignment of caseworkers as an...

The COVID-19 related public health emergency led to federal legislation that changed the landscape of Medicaid coverage for low-income people in the United States. Beginning in 2020, policy responses led to a surge in Medicaid enrollment due to federal rules preventing Medicaid disenrollment,...

How do administrative burdens influence enrollment in different welfare programs? Who is screened out at a given stage? This paper studies the impacts of increased administrative burdens associated with the automation of welfare caseworker assistance, leveraging a unique natural experiment in...
