We study social learning and innovation in an overlapping generations model, emphasizing the trade-off between marginal innovation (combining existing technologies) and radical innovation (breaking new ground). We characterize both short-term and long-term dynamics of innovation, and the...

How do successive, forward-looking agents experiment with interdependent and endogenous technologies? In this paper, trying a radically new technology not only is informative of the value of similar technologies, but also reduces the cost of experimenting with them, in effect expanding the space...

Do agents believe to be agreeing more with others in the long-run? This paper designs an experiment to study how cognitive abilities affect actual and perceived disagreement in a standard sequential belief updating task with public signals. We document a persistent gap in the perception of...

We design a laboratory experiment to study behavior in a multidivisional organization. The organization faces a trade-off between coordinating its decisions across the divisions and meeting division-specific needs that are known only to the division managers, who can communicate their private...

Many facts are learned through the intermediation of individuals with special access to information, such as law enforcement officers, officials with a security clearance, or experts with specific knowledge. This paper considers whether societies can learn about such facts when information is...

Can workers from social groups of comparable productivities obtain comparable employment opportunities in the long run? We model dynamic hiring and employer learning via a general Poisson multi-armed bandit framework. Breakdown environments that reveal on-the-job mistakes rather than successes...

How does renegotiation affect contracts between a principal and an agent subject to persistent private information and moral hazard? This paper introduces a concept of renegotiation-proofness, which adapts to stochastic games the concepts of weak renegotiation-proofness and internal consistency...

This paper argues that, to be forward-looking in a logically consistent sense, a decision maker must take account of his overall well-being, not just his instantaneous utility, in all future periods. However, such a decision-maker is necessarily time inconsistent. The paper explores the...
