Revealed preference theory offers a criterion for decision-making quality: if decisions are high quality then there exists a utility function that the choices maximize. We conduct a large-scale field experiment that enables us to test subjects' choices for consistency with utility maximization...

This paper considers the observational implications of social influences on adoption decisions for an environment of perfect foresight adopters. We argue that social influences can produce two observable effects: 1) discontinuities in unconditional adoption curves and 2) pattern reversals in...

Are CEOs' attitudes and beliefs linked to their fims' innovative performance? This paper uses Malmendier and Tate's measure of overconfidence, based on CEO stock-option exercise, to study the relationship between a CEO's "revealed beliefs" about future performance and standard measures of...

Due to improving information technology, the growing complexity of research problems, and policies designed to foster interdisciplinary research, the practice of science in the United States has undergone significant structural change. Using a sample of 110 top U.S. universities observed during...

This research examines the climatic origins of the diffusion of Neolithic agriculture across countries and archaeological sites. The theory suggests that a foraging society s history of climatic shocks shaped the timing of its adoption of farming. Specifically, as long as climatic disturbances...

Countries who adopted regulation of coal-fired power plants after 1980 generally did so at a much lower level of per-capita income than did early adopters -- poor countries regulated sooner. This phenomenon suggests that pioneering adopters of environmental regulation provide an advantage to...

Short-run subsidies for health products are common in poor countries. How do they affect long-run adoption? We present a model of technology adoption in which people learn about a technology's effectiveness by using it (or observing others using it) for some time, but people quit using it too...

This paper provides the first real-world evidence of Giffen behavior, i.e., upward sloping demand. Subsidizing the prices of dietary staples for extremely poor households in two provinces of China, we find strong evidence of Giffen behavior for rice in Hunan, and weaker evidence for wheat in...

We investigate whether information technology can help physicians more efficiently acquire new knowledge in a clinical environment characterized by information overload. Our analysis makes use of data from a randomized trial as well as a theoretical model of the influence that information...

When choice options are complex, policy makers may seek to reduce decision making errors by making a high quality option the default. We show that this positive effect is at risk because such a policy creates incentives for decision makers to "drop out" by paying no attention to the decision and...
