Bringing scholars and policymakers to the frontiers of research and addressing the critical issues of the day, the book presents original important new theoretical and empirical results. The distinguished contributors include: P. Agrel, K. Alexander, J. Crémer, X. Dassiou, G. Deltas, F. Etro,...

In this paper, we explore the hypothesis that an important force behind the collapse in advertising revenue experienced by newspapers over the past decade is the greater consumer switching facilitated by online consumption of news. We introduce a model of the market for advertising on news media...

This paper develops a fairly general model of platform competition in media markets allowing viewers to use multiple platforms. This leads to a new form of competition between platforms, in which they do not steal viewers from each other, but affect the viewer composition and thereby the...

We provide a model of online advertising display markets where consumer attention may be divided among multiple publishers and, consequently, their advertising attention may be allocated to different platforms. We demonstrate that this gives rise to a mixture of single- and multi-homing...

In media markets, consumers spread their attention to several outlets, increasingly so as consumption migrates online. The traditional framework for studying competition among media outlets rules out this behavior by assumption. We propose a new model that allows consumers to choose multiple...

Payment card networks, such as Visa, require merchants' banks to pay substantial "interchange" fees to cardholders' banks, on a per transaction basis. This paper shows that a network's profit-maximizing fee induces an inefficient price structure, over-subsidizing card usage and over-taxing...

Payment card networks, such as Visa, require merchants' banks to pay substantial quot;interchangequot; fees to cardholders' banks, on a per transaction basis. This paper shows that a network's profit-maximizing fee induces an inefficient price structure, over-subsidizing card usage and...

We develop and estimate a model of dynamic interactions where commitment is limited and contracts are incomplete to explain the patterns of income and consumption growth in village economies of less developed countries. Households can insure through both formal contracts and informal agreements,...

This paper analyzes how learning behaviors can substantially modify the outcome of competition in an oligopolistic industry facing demand uncertainty. We consider the case of a symmetric duopoly game where firms have imperfect information about market demand and learn through observing the...
