We examine the role of generalized constant gain stochastic gradient (SGCG) learning in generating large deviations of an endogenous variable from its rational expectations value. We show analytically that these large deviations can occur with a frequency associated with a fat tailed...

The extant experimental design to investigate warm glow and altruism elicits a single measure of crowd-out. Not recognizing that impure altruism predicts crowd-out is a function of giving-by-others, this design's power to reject pure altruism varies with the level of giving-by-others, and it...

The public phase of a capital campaign is typically launched with the announcement of a large seed donation. Andreoni (1998) argues that such a fundraising strategy may be particularly effective when funds are being raised for projects that have fixed production costs. The reason is that when...
