A growing literature uses now widely available data on beliefs and expectations in the estimation of structural models. In this chapter, we review this literature, with an emphasis on models of individual and household behavior. We first show how expectations data have been used to relax strong...

Wealthier individuals have stronger incentives to seek higher returns. We investigate theoretically the effect this has on long-run wealth inequality. Incorporating capital management into a standard RamseyCass-Koopmans model generates substantial long-run inequality: the majority of the...

Equilibrium assumptions posit relations between different people's beliefs and behavior without describing a process that causes these relations to hold. I show that because equilibrium models do not describe a causal process whereby one endogenous variable affects another, attempts to decompose...

The productivity of Indonesian agri-food, especially rice, has been declining over the last decade. A decreasing emphasis on technology innovation and dissemination has been cited as a possible cause of this problem. Information and communication technologies (ICTs) can play a crucial role in...

In the digital age, privacy in economic activities is increasingly threatened. In considering policies to address this threat, it is useful to consider what value, if any, that people attach to privacy in economic activities. We study this question by eliciting individuals' willingness to pay...

This paper investigates the value of recommendations for disseminating economic information, with a focus on frictions resulting from preference heterogeneity. We consider Bayesian expected-payoff maximizers who receive non-strategic recommendations by other consumers. The paper provides...

This paper considers competitive search equilibrium in a market for a good whose quality differs across sellers. Each seller knows the quality of the good that he or she is offering for sale, but buyers cannot observe quality directly. We thus have a "market for lemons" with competitive search...

This paper investigates the value of recommendations for disseminating economic information, with a focus on frictions resulting from preference heterogeneity. We consider Bayesian expected-payoff maximizers who receive non-strategic recommendations by other consumers. The paper provides...

We consider a dynamic model in which a principal decides what information to release about a product of unknown quality (e.g., a vaccine) to incentivize agents to experiment with the product. Assuming that the agents are long-lived and forward-looking, their incentive to wait and see other...
