In this paper we study the relevance and mechanics of consumption network effects. We use long panel data on the entire Danish population to construct a measure of consumption based on administrative tax records, and define the peer groups in terms of workplace, occupation, education, and age....

Peer influence through word-of-mouth (WOM) plays an important role in many information systems but identification of causal effects is challenging. We identify causal WOM effects in the empirical setting of game adoption in a social network for gamers by exploiting differences in individuals’...

We introduce a price oligopoly model with informed and uninformed consumers, thus creating a new channel of influence for collaborative R&D. Firms can establish pair-wise collaborative research links with other firms to lower production costs. Informed consumers buy from the lowest cost firms...

This paper examines the informativeness of consumer information networks and their effect on price competition between firms. Under the proposed information mechanism, consumers share their initial information with the members of their network and as such become better informed. The main result...

We study the problem of optimal dynamic pricing for a monopolist selling a product to consumers in a social network. In the proposed model, the only means of spread of information about the product is via Word of Mouth communication; consumers' knowledge of the product is only through friends...

Understanding the process of software adoption is of paramount importance to software start-ups. We study a monopolistic seller's optimal consumer network structure formation (seeding, segmentation, sequencing, and pricing strategies) under network effects. We demonstrate the importance of...

The discrete choice literature has evolved from the analysis of a choice of a single item from a fixed choice set to the incorporation of a vast array of more complex representations of preferences and choice set formation processes into choice models. Modern discrete choice models include rich...

We introduce a price oligopoly model with informed and uninformed consumers, thus creating a new channel of influence for collaborative R&D. Firms can establish pair-wise collaborative research links with other firms to lower production costs. Informed consumers buy from the lowest cost firms...

In markets with search frictions, consumers can acquire information about goods either through costly search or from friends via word-of-mouth (WOM) communication. How do sellers’ market power react to a very large increase in the number of consumers’ friends with whom they engage in WOM?...
