Based on the frictional matching framework, the paper provides a theoretical model for a specic type of two-sided platform: The buyer- seller transaction platform. In the model, the number of participants and the source of network externalities are endogenously determined. The platform is shown...

Although firms are dispersed across space and may face radically different production conditions, this dimension of firm heterogeneity is often overlooked. Differences between factor markets, especially for labor, are stark. To pursue this line of inquiry, we model firm hiring across local labor...

Zimbabwean villagers of distinct background have resettled in government organized land reforms for more than three decades. Against this backdrop, I assess the level of social cohesion in some of the newly established communities by estimating average preferences for fairness in a structural...

In the introduction to the special issue, we discusses the important role of economic theory in drawing inferences about behavior from data. The papers in the special issue represent several different approaches to theory-based empirical analysis, ranging from "full solution" methods to the...

Cellular phone carriers typically offer complicated nonlinear tariffs. Consumers make a discrete choice among several rate plans. Each plan has a nonlinear price schedule, and price is usually lower for in-network calls. I present an empirical framework to estimate demand under such nonlinear...

DSGE models are currently estimated with a two step approach: data is first filtered and then DSGE structural parameters are estimated. Two step procedures have problems, ranging from trend misspecification to wrong assumption about the correlation between trend and cycles. In this paper, I...

We construct a model to show that outsourcing of a crucial input can occur even though it can be produced in-house at a lower cost. There are two firms producing differentiated goods and competing in prices, and only one of them possesses input production technology which is superior to that of...

We consider consumers with the same reservation price, who desire to buy at most one unit of a good. Firms compete only in prices but there are other features firms cannot control that would eventually lead an agent to buy in one firm or another. We introduce such uncertainty in a model of a...

This paper proposes a model in which identical sellers of a homogenous product compete in both prices and price frames (i.e., ways to present price information). We model price framing by assuming that firms’ frame choices affect the comparability of their price offers: consumers may fail to...
