People may be surprised by noticing certain regularities that hold in existing knowledge they have had for some time. That is, they may learn without getting new factual information. We argue that this can be partly explained by computational complexity. We show that, given a knowledge base,...

Technological progress is typically a result of trial-and-error research by competing firms. While some research paths lead to the innovation sought, others result in dead ends. Because firms benefit from their competitors working in the wrong direction, they do not reveal their dead-end...

This paper studies the aggregate consequences of individual learning in the labor market. Specifically, I examine this issue in a model of directed search on the job. Once matched, a firm-worker pair gradually learns the match-specific quality, taking the history of realized production as...

People may be surprised by noticing certain regularities that hold in existing knowledge they have had for some time. That is, they may learn without getting new factual information. We argue that this can be partly explained by computational complexity. We show that, given a database, finding a...

This paper demonstrates that a misspecified model of information processing interferes with long-run learning and offers an explanation for why individuals may continue to choose an inefficient action, despite sufficient public information to learn the true state. I consider a social learning...

This paper studies the dynamics of workers. on-the-job search behavior and its consequences in an equilibrium labor market. In a model with both directed search and learning about the match quality of firm-worker pairs, I highlight the job search target effect of learning: as a worker updates...

We study dynamic bargaining with uncertainty over the buyer's valuation and the seller's outside option. A long-lived seller makes offers to a long-lived buyer whose value is private information. There may exist a short-lived buyer whose value is higher than that of the long-lived buyer. The...
