We develop and test a simple model of limited attention in intertemporal choice. The model posits that individuals fully attend to consumption in all periods but fail to attend to some future lumpy expenditure opportunities. This asymmetry generates some predictions that overlap with models of...

A simple theory is developed which formally describes how charities can resolve the information asymmetry problems faced by small donors by working with large donors to generate quality signals. To test the model, two large-scale natural field experiments were conducted. In the first experiment,...
