Short-run subsidies for health products are common in poor countries. How do they affect long-run adoption? We present a model of technology adoption in which people learn about a technology's effectiveness by using it (or observing others using it) for some time, but people quit using it too...

This paper explores the characteristics of 238 patents on 94 "inventions" contributed by major multinational innovators to the "Eco-Patent Commons", which provides royalty-free access to third parties to patented climate change related innovations. By comparing the pledged patents to other...

In many markets, including the new U.S. Exchanges, health insurance plans are paid by risk-adjusted capitation, in some markets combined with reinsurance and other payment mechanisms. This paper proposes three metrics for analyzing the insurer incentives embedded in these complex payment...

This paper exploits the seasonal and annual changes in marginal prices for water to estimate the price elasticity of demand by residential households for water. It uses the changes in distributions of water using the census block group levels in response to changes in marginal prices of water...

Paid maternity leave has gained greater salience in the past few decades as mothers have increasingly entered the workforce. Indeed, the median number of weeks of paid leave to mothers among OECD countries was 14 in 1980, but had risen to 42 by 2011. We assess the case for paid maternity leave,...

Historically, low Medicaid reimbursement rates have limited the willingness of health care providers to accept Medicaid patients, leading to access problems in many communities. This problem has been especially acute in the case of dental care. We combine data from several sources to examine the...

The problem of the uninsured - those eschewing the purchase of health insurance policies - cannot be fully understood without considering informal alternatives to market insurance called "self-insurance" and "self-protection", including the publicly and charitably-financed safety-net health care...

The efficiency properties of price and non-price instruments for conservation in environmental policy are well understood. Yet, there is little evidence comparing the effectiveness of these instruments, especially when considering water resource management. We exploit a rich panel of residential...

Measuring the overall impact of public health insurance receipt is important in an era of increased access to publicly-provided and subsidized insurance. Although government expansion of health insurance to older workers leads to labor supply reductions for recipients, there may be spillover...

Epple and Romano (1998) show equilibrium provision of education by public and private schools has the latter skim off the wealthiest and most-able students, and flat-rate vouchers lead to further cream skimming. Here we study voucher design that would inject private-school competition and...
