Many U.S. states have passed legislation providing leave to organ and bone marrow donors and/or tax benefits for live and deceased organ and bone marrow donations and to employers of donors. We exploit cross-state variation in the timing of such legislation to analyze its impact on organ donations by living and deceased persons, on measures of the quality(More)
We conducted a field experiment with the American Red Cross to study the effects of economic incentives on volunteer activities. The experiment was designed to assess local and short-term effects, but also spatial and temporal substitution, heterogeneity and spillovers. Subjects offered $5, $10, and $15 gift cards to give blood were more likely to donate,(More)
We present evidence from a natural field experiment involving nearly 100,000 individuals on the effects of offering economic incentives for blood donations. Subjects who were offered economic rewards to donate blood were more likely to donate, and more so the higher the value of the rewards. They were also more likely to attract others to donate, spatially(More)
A competitive general equilibrium model with complete collateralized contracts under limited commitment is proposed and analyzed. With limited aggregate collateral, risk sharing is imperfect. There exists a minimal spanning set of finite collateralized contracts that generates the feasible space and that contains more than the complete set of collateralized(More)

In this paper, I analyze the influence of labor market conditions on wages by considering an insurance model of the employment relationship. The model allows for limited commitment on both sides of the labor contract, and has three main implications: First, wages can be correlated with both the best and the worst labor market conditions since the start of a(More)
We investigate the eect of female leadership on gender-specic wage distributions and rm performance using a unique Italian matched employer-employee panel data set. We nd that female executives increase the variance of women's wages within rms due to a positive impact on wages at the top of the distribution, and a negative impact on wages at the bottom.(More)
