This paper makes three contributions to the literature on private provision of public goods. First, we identify limitations of the frequently used specification test that distinguishes between the standard models of pure and impure altruism based on the extent of crowding out. While the...

We explore the importance of activism in the context of Earth Day. We use variation in weather to study the long-term effects of the original Earth Day on attitudes, environmental outcomes, and children's health. Unusually bad weather in a community on April 22, 1970, is associated 10 to 20...

Despite the increasing use by charities, significant uncertainty exists about optimal online fundraising mechanisms, especially when large donor pools show substantial heterogeneities. We use an online natural field experiment with over 700,000 subjects to test theory on price discounts and show...

Estimates of volunteering in the United States vary greatly from survey to survey and do not show the decline over time common to other measures of social capital. We argue that these anomalies are caused by the social processes that determine survey participation, in particular the propensity...

Volunteer activity is work performed without monetary recompense. This paper shows that volunteering is a sizeable economic activity in the U.S.; that volunteers have high skills and opportunity costs of time; that standard labor supply explanations of volunteering account for only a minor part...

Why do individuals volunteer their time even when recipients receive far less value than the donor's opportunity cost? Previous models of altruism that focus on the overall impact of a gift cannot rationalize this behavior, despite its prevalence. We develop a model that relaxes this assumption,...

A primary rationale for public provision of K-12 education and state financing of school spending is that education fosters civic engagement and the development of social capital. However, limited evidence exists on whether and how school spending affects civic engagement. Virtually all studies...

Usinga detailed sample of semi-skilled production workers we find that holding a wide range of personal and job-related characteristics constant, workers assigned to more complex jobs seem to be more likely to quit than are workers assigned to simpler jobs. Job complexity has no discernible...

The prescription drug component of the Consumer Price Index (CPI measures recent and past drug price changes, and provides the basis for projecting future price trends and health care expenditures. However, there are concerns about the adequacy of the price data because of recent changes in the...

To identify the determinants of social capital formation, it is necessary to understand the social capital investment decision of individuals. Individual social capital should then be aggregated to measure the social capital of a community. This paper assembles the evidence that supports the...
