How do social networks affect the diffusion of information? While previous research has mainly focused on the spread of specific messages, we study how the overall mix of information that diffuses through multiple intermediaries can become distorted or biased based on what categories of...

Using data from a novel laboratory experiment on complex problem solving in which we varied the network structure of 16-person organizations, we investigate how an organization’s network structure shapes performance in problem-solving tasks. Problem solving, we argue, involves both search for...

We introduce a new statistic, 'spectral goodness of fit' (SGOF) to measure how well a network model explains the structure of an observed network. SGOF provides an absolute measure of fit, analogous to the standard R-squared in linear regression. Additionally, as it takes advantage of the...

By lowering search costs, making more products available, and providing access to free content, information technology (IT) has changed patterns of market concentration in media industries such as recorded music. In this paper, I argue that to understand how IT has changed media markets we need...

In contrast to the logic that international trade leads to greater specialization and differentiation of products, cultural industries are often still protected from imports, in part, because of the worry that trade will lead instead to homogenization. Is this true for cultural goods and if so,...

Given that tastes differ in different markets, how do producers in one market begin to export to other markets? Is it better to be insulated from or influenced by products from outside? I seek an answer to this question by modeling international trade in music recordings as a macroscopic...

A key property of the World Wide Web is the possibility for firms toplace virtually costless links to third-party content as a substitute orcomplement to their own content. This ability to hyperlink has enablednew types of players, such as search engines and content aggregators, tosuccessfully...
