This paper tests the broadly adopted assumption that people apply a single discount rate to the utility from different sources of consumption. Using unique data from two surveys conducted in rural Uganda including both hypothetical and real choices over different goods, the paper elicits time...

We study collective decisions by time-discounting individuals choosing a common consumption stream. We show that with any heterogeneity in time preferences, every Pareto efficient and non-dictatorial method of aggregating utility functions must be time-inconsistent. We also show that decisions...

Adaptation is omnipresent but people systematically fail to correctly anticipate the degree to which they adapt. This leads individuals to make inefficient intertemporal decisions. This paper concerns optimal income taxation to correct for such anticipation-biases in a framework where consumers...

This paper examines whether myopia (misperception of the long-term care (LTC) risk) and private insurance market loading costs can justify social LTC insurance and/or the subsidization of private insurance. We use a two-period model wherein individuals differ in three unobservable...

I derive a simple closed-form formula for the optimal tax on addictive goods when consumers with hyperbolic time preferences erroneously and naïvely believe that they will go through with the consumption plan they devise in the present. In the literature, this problem is well studied for...

Conditional Cash Transfer programs are designed to increase human capital in poorer families. They do this directly through incentives and conditions. A further way in which these programs may influence household decisions is through impacts on preferences. Preferences may change as a result of...
