We use variation in wind speeds at surfing locations in Switzerland as exogenous shifters of users' propensity to post content about their surfing activity onto an online social network. We exploit this variation to test whether users' social ties on the network have a causal effect on their...

This paper proposes methods for identifying indirect network effects with dynamically optimizing consumers purchasing a durable hardware good and associated software. We apply this model to data drawn from the DVD player and titles markets. We observe model-level prices, sales and...

Conventional hedonic analysis measures willingness to pay for attributes on the basis of marginal fixed costs. We argue that in many cases variable costs are also affected by these attributes and that this should be taken into account. We develop a simple model to show that the marginal...

This paper examines the importance of indirect network effects in the U.S. video game market between 1994 and 2002. The diffusion of game systems is analyzed by the interaction between console adoption decisions and software supply decisions. Estimation results suggest that introductory pricing...

Conventional hedonic analysis measures willingness to pay for attributes on the basis of marginal fixed costs. We argue that in many cases variable costs are also affected by these attributes and that this should be taken into account. We develop a simple model to show that the marginal...

This paper studies how morale in teams can break down. It interprets high morale as team members working together productively, either because of a sense of fairness or because of implicit incentives from repeated interactions. Team members learn that lay-offs will occur at a fixed future date,...

This paper explores differences in consumers' grocery shopping behavior when they shop online and in a brick-and-mortar store. To do so, I assemble a new scanner dataset that tracks customers' grocery purchases in-store and on the Internet. This allows comparison in behavior of the same...

This paper studies the role of firm heterogeneity and information spillovers in the sourcing decision to provide web services. To this end, we develop a theoretical model that relates these factors to firms' decisions to outsource or use in-house resources (insource). Based on this theoretical...

This paper investigates the price war in the UK quality newspaper industry in the 1990s. We build a model of the newspaper market which encompasses demand for differentiated products on both, the readers and advertisers side of the market, and profit maximization by four competing oligopolistic...

In this paper we want to analyze the internal divisional structure within an organi-
