We designed four observational learning experiments to identify the key channels that, along with Bayes-rational inferences, drive herd behavior. In Experiment 1, unobserved, whose actions remain private, learn from the public actions made in turn by subjects endowed with private signals of...

Explaining individual behavior in politics should rely on the same motivational assumptions as explaining behavior in the market: That’s what Political Economy, understood as the application of economics to the study of political processes, is all about. In its standard variant, those who...

We study the effects of two widely observed behavioral policy interventions⸻the simplification of complex decisions and the implementation of high-quality defaults. Based on a laboratory experiment featuring a dual-task paradigm, we demonstrate that these policies do not only improve decisions...

This paper estimates a New Keynesian model with new and old behavioral elements. Agents in the model exhibit cognitive discounting, or myopia: they discount variables far into the future at higher rates than typically implied in the benchmark model. We investigate the model under different...

Evidence from hypothetical scenarios strongly suggests the existence of a sunk cost bias, the tendency to ‘throw good money after bad money.’ However, the few studies using incentives are inconclusive. In addition, evidence on potential psychological channels underlying such a bias is...

Procrastination is often attributed to time-inconsistent preferences but may also arise when individuals derive anticipatory utility from holding optimistic beliefs about their future effort costs. This study provides a rigorous empirical test for this notion of ‘motivated procrastination’....

Implicit contracts can mitigate moral hazard in labor, credit and product markets. The enforcement mechanism underlying an implicit contract is the threat of exclusion: the agent fears that he will lose future income if the principal breaks off the relationship. This threat may be very weak in...

Investors' return expectations are pivotal in stock markets, but the reasoning behind these expectations remains a black box for economists. This paper sheds light on economic agents' mental models - their subjective understanding - of the stock market, drawing on surveys with the US general...
