We build a model of competition between strategic data intermediaries collecting consumer information that they sell to firms competing in a product market. Each intermediary has access to exclusive information on a group of consumers and competes with other intermediaries on a common group of...

We investigate the strategies of a data intermediary selling consumer information to firms for price discrimination purpose. We analyze how the mechanism through which the data intermediary sells information influences how much consumer information she will collect and sell to firms, and how...

A monopolist data intermediary collects consumer information that it strategically sells to competing firms in a product market for price discrimination purposes. The intermediary charges a price of information and chooses the optimal partition that maximizes the willingness to pay of firms for...

This paper investigates the strategies of a data broker in selling information to one or to two competing firms that can price-discriminate consumers. The data broker can strategically choose any segment of the consumer demand (information structure) to sell to firms that implement third-degree...

Large, generalist, technology firms-so-called "big-tech" firms-powerful in their primary market, routinely enter secondary markets consisting of specialist firms. Naturally, one might expect a specialist firm to be fiercely protective of its data as a way to maintain its market position in the...

Using micro-level data coming from household surveys over 5 years, from 2013 to 2017, we analyse what are the determinants of mobile broadband adoption in developing economies. We provide empirical evidence on the presence of a learning effect stemming from mobile money use, which by providing a...

Broadband is seen as a vector of economic growth and social development. In the developing world, mobile technologies are widely adopted and mobile broadband is progressively rolled-out with high expectations on its impact on the countries' development. We highlight what the determinants of...
