Educational interventions are often evaluated and compared on the basis of their impacts on test scores. Decades of research have produced two empirical regularities: interventions in later grades tend to have smaller effects than the same interventions in earlier grades, and the test score...

This study examines the effect of experience and knowledge on weather insurance adoption. First, we conduct insurance games with farmers, and find that the treatment improves real insurance take-up by 46%. The effect is not driven by changes in risk attitudes and perceived probability of...

We study whether current spending levels and public knowledge of them contribute to transatlantic differences in policy preferences by implementing parallel survey experiments in Germany and the United States. In both countries, support for increased education spending and teacher salaries falls...

This paper examines the role of knowledge elites in modernization. At the eve of the French Revolution, in the spring of 1789, King Louis XVI solicited lists of grievances (Cahiers de Doléances), in which the public could express complaints and suggestions for reforms of the Ancien Regime. We...

Innovation is often predicated on discovering useful new combinations of existing knowledge in highly complex knowledge spaces. These needle-in-a-haystack type problems are pervasive in fields like genomics, drug discovery, materials science, and particle physics. We develop a...

Do differences in health literacy contribute to the widely documented health-income gradient? In the context of Sweden, we document a strong relationship between exposure to health-related expertise – captured by the presence of a health professional in the family – and health. Exposure to...

There is growing public interest in alternatives to intellectual property including, but not limited to, prizes and government grants. We argue that there is no single best mechanism for supporting research. Rather, mechanisms can only be compared within specific creative environments. We...

This paper investigates, theoretically and empirically, a possibly fundamental aspect of technological progress. If knowledge accumulates as technology progresses, then successive generations of innovators may face an increasing educational burden. Innovators can compensate in their education by...

Using data from the Health and Retirement Study, this paper creates variables measuring knowledge about future social security and pension benefits by comparing respondent reports of their expected benefits with benefits calculated from social security earnings records and employer provided...
