We analyse the effects of network externalities in strategic R&D competition. We present a model of two firms competing with R&D investments and prices in a differentiated consumer market. Buyers form firm-specific networks which can be compatible. A high degree of compatibility and large...

Platform interoperability is considered a powerful tool to promote competition in digital markets when network effects are at play. We study the effect of interoperability on competition between two ad-financed platforms, allowing for endogenous multi-homing of consumers. When the platforms are...

We examine a Bertrand competition game between two intermediaries offering matching services between two sides of a market. Indirect network externalities arise as the probability of finding one's match with a given intermediary increase with the number of agents of the other side who use the...

We study the dynamics of an oligopoly market with network externalities. In contrast to earlier work, we consider a model where products are vertically differentiated and the number of firms is arbitrary. We show that the degree of network externalities has a one-to-one relationship with the...

As the network externality in an industrial organization has been widely discussed in recent years, many researchers in the field have noted a particular type of market, the so-called two-sided market. In a two-sided market, two or more groups of agents such as buyers and sellers interact while...

This Paper examines competition between a dominant network and a challenging network with third-degree or perfect price-discrimination, allowing for arbitrary configurations of network externalities, as well as horizontal and vertical product differentiation. Domination in the coordination game...

Compatibility of network products is an important issue in markets for communication technology as well as hard- and software products. Empirical findings suggest that firms competing in these markets typically choose intermediate degrees of product compatibility. We present a strategic...

This paper reviews the empirical evidence on commercial media bias (i.e., advertisers influence over media accuracy) and then introduces a simple model to summarize the main elements of the theoretical literature. The analysis provides three main policy insights for media regulators: i) Media...

In this paper we investigate whether markets with heterogeneous network externalities can belocked-in by old technologies even if superior technologies are available. Heterogeneous networkexternalities are present when some consumers care more about the size of the market share of agood than...

We examine tippy network markets that accommodate price discrimination. The analysis shows that when a mild equilibrium refinement, the monotonicity criterion, is adopted, network competition may have a unique subgame-perfect equilibrium regarding the winner's identity; the prevailing brand may...
