This paper provides a systematic analysis of identification in linear social interactions models. This is both a theoretical and an econometric exercise as the analysis is linked to a rigorously delineated model of interdependent decisions. We develop an incomplete information game that...

The authors test opposing theories on how urban locations influenced the diffusion of Internet technology. They find evidence that, controlling for industry, participation in the Internet is more likely in rural areas than in urban areas. Nevertheless, talk of the dissolution of cities is...

Our study provides the first census of the dispersion of Internet technology to commercial establishments in the United States. We distinguish between participation, that is, use of the Internet because it is necessary for all business (e.g., email and browsing) and enhancement, that is,...

How much do internal firm resources contribute to technology adoption in major urban locations, where the advantages from agglomeration are greatest? The authors address this question in the context of a business's decision to adopt advanced Internet technology. Drawing on a rich data set of...

Perhaps the most striking feature of "crowdfunding" is the broad geographic dispersion of investors in small, early-stage projects. This contrasts with existing theories that predict entrepreneurs and investors will be co-located due to distance-sensitive costs. We examine a crowdfunding setting...

We report evidence indicating that Bitnet adoption facilitated increased research collaboration between US universities. However, not all institutions benefited equally. Using panel data from seven top engineering journals, Bitnet connection records, and a variety of institution ranking data, we...

How did the diffusion of the internet affect regional wage inequality? We examine the relationship between business use of advanced internet technology and local variation in US wage growth between 1995 and 2000. We find no evidence that the internet contributed to regional wage convergence....

We examine the relationship between the diffusion of advanced internet technology and the geographic concentration of invention, as measured by patents. First, we show that patenting became more concentrated from the early 1990s to the early 2000s and, similarly, that counties that were leaders...

The extant literature linking slack time to innovation focuses on how slack time facilitates creative activities such as ideation, experimentation, and prototype development. We turn attention to how slack time may enable activities that are less creative but still important for innovation,...
