This paper examines the impact of targeting technology on competition between local and general outlets. In the absence of targeting (say, of location), local outlets have an advantage in that there is a tighter match between readers and local consumers that advertisers wish to attract....

In a dynamic environment where underlying competition is “for the market,” this paper examines what happens when entrants and incumbents can instead negotiate for the market. For instance, this might arise when an entrant innovator can choose to license to or be acquired by an incumbent...

We examine competition amongst ridesharing platforms where firms compete by choosing both the price of rides and the extent of idleness. Idleness means drivers who are compensated without picking up passengers, instead acting to reduce passenger wait time. We show that when consumers are the...

We examine competition amongst ridesharing platforms, where firms compete on both price and the wait time induced with idled drivers. We show that when consumers are the only agents who multihome, idleness is lower in duopoly than when consumers face a monopoly ridesharing platform. When drivers...

This paper demonstrates that low (below marginal cost) interconnect or access charges can be used to sustain high subscription prices in an environment of network competition with two-part tariffs and price discrimination. This result stands in contrast to other results in the literature...

This paper examines the influence of mobile network competition on the prices of fixed-to-mobile calls. Because fixed line customers cannot, in general, distinguish the identity of a specific mobile network, these networks have market power when setting termination charges for calls from fixed...

Economists have often viewed the adoption of artificial intelligence (AI) as a standard process innovation where we expect that efficiency will drive adoption in competitive markets. This paper models AI based on recent advances in machine learning that allow firms to engage in better...
