In thinly traded markets for heterogenous, durable goods, such as housing, intermediaries may play especially important roles. Using a unique micro-level dataset of housing transactions in Los Angeles from 1988-2008 and a novel research design, we identify and measure the importance of two very...

We construct daily house price indexes for ten major U.S. metropolitan areas. Our calculations are based on a comprehensive database of several million residential property transactions and a standard repeat-sales method that closely mimics the procedure used in the construction of the popular...

We present an econometric framework for robust pricing based on credible assumptions about consumer behavior. First, we introduce a panel data discrete choice model whose realistic assumptions about consumer behavior result in partial identification of preferences. Next we address the resulting...

We examine the market power of a seller who repeatedly offers upgraded versions of a product. In the case of pure monopoly, the seller also controls compatibility across versions. In the case of an entrant who offers an upgrade, the incumbent seller also controls subsequent interoperability...

This paper explores the endogenous joint evolution of demand and supply in new markets. Firms and consumers learn, in a Bayesian fashion, by observing the behavior of other firms and consumers, respectively. As a result, endogenous information diffusion takes place on both sides of the market....

We examine a horizontal product differentiation duopoly model where firms are also differentiated with respect to the quality of their products. Firms first choose their locations and then compete in prices. It is shown that, whereas the low quality firm prefers to locate as far as possible from...

Endogenous growth requires that non-reproducible factors of production be either augmented or eliminated. Attention heretofore has focused almost exclusively on augmentation. In contrast, we study factor elimination. Maximizing agents decide when to reduce the importance of non-reproducible...

We study the interactions between technological change, resource scarcity and population dynamics in a Schumpeterian model with endogenous fertility. There exists a pseudo-Malthusian equilibrium in which population is constant and income grows exponentially: the equilibrium population level is...

We study the interactions between technological change, resource scarcity and population dynamics in a Schumpeterian model with endogenous fertility. We find a pseudo-Malthusian equilibrium in which population is constant and determined by resource scarcity while income grows exponentially. If...
