Consider an investor who fears ruin when facing investments that satisfy no-arbitrage. Before investing he can purchase information about the state of nature as an information structure. Given his prior, information structure α investment dominates information structure β if, whenever he...

Revealed preference theory offers a criterion for decision-making quality: if decisions are high quality then there exists a utility function the choices maximize. We conduct a large-scale experiment to test for consistency with utility maximization. Consistency scores vary markedly within and...

We experimentally test an endogenous-timing investment model in which subjects privately observe their cost of investing and a signal correlated with the common investment return. Subjects overinvest, relative to Nash. We separately consider whether subjects draw inferences, in hindsight, and...

This paper analyzes how asset prices in a binary market react to information when traders have heterogeneous prior beliefs. We show that the competitive equilibrium price underreacts to information when there is a bound to the amount of money traders are allowed to invest. Underreaction is more...

We document three remarkable features of the Opower program, in which social comparison-based home energy reports are repeatedly mailed to more than six million households nationwide. First, initial reports cause high-frequency "action and backsliding," but these cycles attenuate over time....

Implementation theory assumes that participants' choices are rational, in the sense of being consistent with the maximization of a context- independent preference. The paper investigates implementation under complete information when individuals' choices need not be rational.

We investigate Schelling's hypothesis that payoff-irrelevant labels ("cues") can influence the outcomes of bargaining games with communication. In our experimental games, players negotiate over the division of a surplus by claiming valuable objects that have payoff-irrelevant spatial locations....

In this paper we analyze elections when voters underestimate the correlation between their information sources ("correlation neglect"). We find that this cognitive bias can improve political outcomes. We show that the extreme beliefs which result from correlation neglect induce some voters to...
