Extensive research in economics explores generosity in monetary allocations. However, generosity often involves the allocation of non-monetary goods or experiences. Existing evidence suggests that generosity may be higher in such contexts, though no direct comparison exists. Here, we compare...

The current British Government's "Big Society" plan is based on the idea that granting more freedom to local communities and volunteers will compensate for a withdrawal of public agencies and spending. This idea is grounded on a widely held belief about the relationship between government and...

The paper analyzes econometric models of altruistic giving in dictator and public goods games. Using existing data sets, I evaluate internal and external validity of "atheoretic" regression models as well as structural models of random behavior, random coefficients, and random utility,...
