We study a large-scale French reform that provided generous downside insurance for unemployed individuals starting a business. We study whether this reform affects the composition of people who are drawn into entrepreneurship. New firms started in response to the reform are, on average, smaller,...

The continued rise in the number of non-elderly Americans without health insurance has led to considerable interest in tax-based policies to raise the level of insurance coverage. This paper describes a detailed microsimulation model that has been developed to evaluate such tax-based polices,...

Does student aid increase college attendance or simply subsidize costs for infra-marginal students? Settling the question empirically is a challenge, because aid is correlated with many characteristics that influence educational investment decisions. A shift in financial aid policy that affects...

We evaluate the costs and benefits of increased medical spending for low birth weight infants. Lifetime spending on low birth weight babies increased by roughly $40,000 per birth between 1950 and 1990. The health improvements resulting from this have been substantial. Infant mortality rates fell...

The durability of health care treatment, the substantial technical change in health care treatment, and the prevalence of third-party payment interact to create substantial difficulty in measuring the price and output of health care. This paper provides a framework for analyzing the demand for...

This paper studies the social value of closing price differentials in financial markets. We show that arbitrage gaps (price differentials between markets) exactly correspond to the marginal social value of executing an arbitrage trade. We further show that arbitrage gaps and measures of price...

The Value of Statistical Life (VSL) is arguably the most important number in benefit-cost analyses of environmental, health, and transportation policies. However, agencies have used a wide range of VSL values. One reason may be the embarrassment of riches when it comes to VSL studies. While...

Electric bikes are a potentially important tool to address global warming since they can be a viable alternative to cars in urban areas. Governments are using subsidies to promote household adoption. Welfare analyses are challenging, requiring pass-through estimates from transactions, incidence...

This paper examines the economic foundations of some recently proposed criteria for evaluating the benefits of social programs. These criteria are appropriate for comparing a class of revenue-constant policies. They replace foundational principles of social opportunity costs with accounting...

We make four main contributions in this paper related to the theory and practice of benefit cost analysis (BCA). First, we show that most BCAs of policy interventions do not consider the welfare consequences in secondary markets, where goods or services can be complements or substitutes to those...
