We develop a simple theoretical framework that identifies time preferences without relying on a particular utility function. Our empirical strategy requires observations about intertemporal consumption allocation decisions made under varying relative prices, and seeks to approximate the marginal...

Fundraising interventions may lift donations and/or shift their composition and timing, making it important to study their effect across charity space and time. We find that major fundraising appeals lift total donations, but surprisingly shift donations to other charities across time. To...

How are substitution in the spatial and in the temporal sense connected? Can estimates based on data with spatial variation be transmitted into values appropriate for exploring temporal variation, and vice versa? This paper, building on, inter alia, Frisch (1959), attempts to give some...
