We develop a parsimonious general equilibrium model where agents allocate time across three activities: production, trade, and leisure. Leisure includes time spent socializing, which economizes transaction costs. Our framework yields multiple equilibria in terms of the number of social ties and...

Some consumers derive utility from buying and using products produced with environmentally friendly practices. Because the use of ecologically sound practices is usually a credence attribute in the final product, means of informing consumers are necessary. Problems of adverse selection can occur...

We generalize the classic Grossman and Laroque (1990) (GL) model of optimal portfolio choice with housing and transaction costs by introducing predictability in house prices. As in the GL model, agents only move to more expensive (cheaper) houses when their wealth-to-housing ratios reach an...

Households systematically overvalue or undervalue their houses. We compute house value misperception as the difference between self-reported and market house values. Misperception is sizable, countercyclical, and persistent. We find that a 1 percent increase in house overvaluation results, on...

Social institutions are persistent regularities in contracting and other relations amongst men and in the unintended consequences of such rule-like behavior. They include morality and law as well as institutions of governance such as branding and advertising. Institutions are studied in all...

This essay provides an elementary, unified introduction to the impacts of transaction, search and switching costs on resource allocation in competitive markets. The emphasis is on incorporating these phenomena into models of price-taking behavior, rather than the more usual treatments with...

This paper analyzes the role of the initial allocation of ownership rights in transactions where parties make relationship-specific investments and contracts are incomplete. If there is high mutual dependence in production, the initial allocation of ownership rights is irrelevant. This result...

Ronald Coase article from 1937, The Nature of the Firm, meant a new way of thinking and conceiving of the world, especially of economic organisations. Coase argued that the firm and the market represent two alternative ways to organise the same transactio
