When looked at individually there is little reason to think that economists lack integrity and are dishonest. Yet, when we look at academic papers written by economists we can see biases. This paper tries to reconcile these two observations by arguing that the constraints the profession sets on...

We analyze the United Nations commodities trade database (UN comtrade), comprised of international commodities exchanges in volume and price with monthly resolution. We introduce a trade impact index to quantify the impact, in terms of distance travelled, of importing a specific food raw...

How do people learn? We assess, in a distribution-free manner, subjects' learning and choice rules in dynamic two …-armed bandit (probabilistic reversal learning) experiments. To aid in identification and estimation, we use auxiliary measures of … subjects' beliefs, in the form of their eye-movements during the experiment. Our estimated choice probabilities and learning …

In a simple two-period model with full … commitment available to the principal, we show that whether learning effects are over- or under-exploited crucially depends on … whether learning effects increase or decrease the principal's uncertainty about agents' costs of production. Hence, what …
