We investigate profit-maximizing versioning plans for an information goods monopolist. The analysis employs data obtained from a web-based field experiment in which potential buyers were offered information goods in varied price-quality configurations. Maximum simulated likelihood (MSL) methods...

We conduct a proper test of the claim that people are overconfident, in the sense that they believe that they are better than others. The results of the experiment we present do not allow us to reject the hypotheses that the data has been generated by perfectly rational, unbiased, and...

Many studies have shown that people display an apparent overconfidence. In particular, it is common for a majority of people to describe themselves as better than average. The literature takes for granted that this better-than-average effect is problematic. We argue, however, that, even...

We analyze the relation between religious beliefs, religious participation, and social cooperation. We focus on religions that instill beliefs about the connection between rewards and punishments and social behavior. We show how religious organizations arise endogenously, and identify a...

We investigate the role discretionary (non-working) time plays in sustaining the gap between individuals’ concern about climate change and their propensity to act on this concern by adopting sustainable consumption practices. Using recent Australian survey data on climate change adaptation, we...

Using data from a randomized experiment in rural China, this paper studies the influence of social networks on weather insurance adoption and the mechanisms through which social networks operate. To quantify network effects, the experiment offers intensive information sessions about the...

I discuss the measurement of world poverty and inequality, with particular attention to the role of purchasing power parity (PPP) price indexes from the International Comparison Project. Global inequality increased with the latest revision of the ICP, and this reduced the global poverty line...

One lingering puzzle is why voluntary contributions to public goods decline over time in experimental and real-world settings. We show that the decline of cooperation is driven by individual preferences for imperfect conditional cooperation. Many people's desire to contribute less than others,...

Subjective probabilities are now collected on a number of large household surveys with the objective of providing data to better understand intertemporal decision making. Comparison of subjective probabilities with actual outcomes shows that the probabilities have considerable predictive power...
