The financial motivation to earn advertising revenue by spreading misinformation has been widely conjectured to be among the main reasons misinformation continues to be prevalent online. Research aimed at reducing the spread of misinformation has so far focused on user-level interventions with...

This paper investigates how the destabilizing of a social network may increase the scope of network externalities, using data on sales of a video-calling system made by a business-to- usiness manufacturer to banking employees and subsequent usage by these customers. The terrorist attacks of 2001...

Patent assertion entities, sometimes known as 'patent trolls,' do not manufacture goods themselves but profit from licensing agreements that they often enforce via the threat of litigation. This paper explores empirically how litigation by one such patent troll affected the sales of medical...

This paper analyzes the role of individual heterogeneity in the diffusion of a network technology. Using a detailed data set on the adoption of a new videoconferencing technology within a firm, we estimate a structural model of technology adoption and use. We find that employees have significant...

We estimate the demand for a videocalling technology in the presence of both network effects and heterogeneity. Using a unique dataset from a large multinational firm, we pose and estimate a fully dynamic model of technology adoption. We propose a novel identification strategy based on...

This paper investigates how the destabilizing of a social network may increase the scope of network externalities, using data on sales of a video-calling system made to an investment bank's employees and subsequent usage by these customers. The terrorist attacks of 2001 led potential customers...

For many services, customers subscribe to long-term contracts. Standard economic theory suggests that customers evaluate a contract as the sum of benefits and payments. We suggest that rather than evaluating multi-period service contracts at the contract-level, customers use period level...

We develop an economic perspective on algorithmic fairness and the surrounding empirical, theoretical and policy issues. Our perspective draws from clear parallels between algorithms and issues in economics of discrimination, crime, personnel and technological innovation; as well as more subtle...
