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...

In many low- and middle-income countries blood donations per capita are substantially lower than in advanced economies. In these countries blood supply is mostly collected through directed donations from relatives and friends to individuals needing transfusions or to replace blood used in...

This paper presents a model and experimental evidence to explain the “volunteering puzzle” where agents prefer volunteering time to donating money when monetary donations are, ceteris paribus, more efficient for providing resources to charity. In the model agents receive heterogeneous...

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...
