How should we measure economic efficiency? The canonical measure is an unweighted sum of willingnesses to pay. In contrast, this paper provides efficient welfare weights that implement the Kaldor-Hicks tests for efficiency but account for the distortionary cost of taxation. The shape of the...

This paper illustrates how one can use causal effects of a policy change to measure its welfare impact without decomposing them into income and substitution effects. Often, a single causal effect suffices: the impact on government revenue. Because these responses vary with the policy in...

Across a wide set of non-group insurance markets, applicants are rejected based on observable, often high-risk, characteristics. This paper argues private information, held by the potential applicant pool, explains rejections. I formulate this argument by developing and testing a model in which...

This paper studies the implications of individuals' knowledge of future job loss for the existence of an unemployment insurance (UI) market. Learning about job loss leads to consumption decreases and spousal labor supply increases. This suggests existing willingness to pay estimates for UI...

The Thai 30 Baht program was one of the largest health system reforms ever undertaken by a low-middle income country. In addition to lowering the cost of care for the previously uninsured in public facilities, it also entailed a fourfold increase in funding provided to hospitals to care for the...

We present new evidence on trends in intergenerational mobility in the United States using administrative earnings records. We find that percentile rank-based measures of intergenerational mobility have remained extremely stable for the 1971–1993 birth cohorts. For children born between 1971...

This paper analyzes Thailand's 2001 healthcare reform, "30 Baht." The program increased funding available to hospitals to care for the poor and reduced copays to 30 Baht (~$0.75). Our estimates suggest the supply-side funding of the program increased healthcare utilization, especially among the...
