Firms can donate a share of profits to charity as a form of corporate social responsibility (CSR). Recent experiments have found that such initiatives can induce higher effort by workers, generating benefits for both sides of the labour market. We design a novel version of the gift-exchange game...

We examine how economic incentives affect pro-social behavior through the analysis of a unique dataset with information on more than 14,000 American Red Cross blood drives. Our findings are consistent with blood donors responding to incentives in a standard way; offering donors economic...

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....

We design an experiment to ask whether morally-motivated behavior, e.g., charitable giving, is history-dependent. Using a popular policy nudge, the default option, we exogenously vary altruism “now” and show that giving “now” causes a 66%- 200% increase in the probability of giving...

We challenge a commonly used assumption in the literature on social preferences and show that this assumption leads to significantly biased estimates of the social preference parameter. Using Monte Carlo simulations, we demonstrate that the literature's common restrictions on the curvature of...
