We analyze the formation of bilateral R&D collaborations in an oligopoly when each firm benefits from the research done by other firms it is connected to. In contrast to myopic stability, farsighted stability leads to R&D networks consisting of two minimally connected components, with the...

Consider the Hotelling linear spatial duopoly with firm uncertainty over the consumer mean. As uncertainty about the mean grows relative to the dispersion of consumers, competitive locations become socially optimal. A limit result for discontinuous, log-concave densities is also established.

Fershtman and Judd (1987) and Sklivas (1987) have shown that strategic delegation under price competition makes firm owners choose incentive contracts that induce managers to be soft in order to reduce competitive intensity. We show in a worked-out example that under sufficiently strong network...

Presenting a novel model of local shopping, the benefit of monopoly provision due to market size effects is explored. Prices are lower, variety and aggregate consumer surplus higher, than local shopping but many shoppers’ utility falls. Policymakers should take care.

We derive conditions under which structural econometric models that rely on numerical computation of equilibria produce consistent and asymptotically normal parameter estimates. The conditions are weaker than those required for the application of the implicit function theory.

Costs necessary to conform with rules and regulations governing market access (i.e. compliance costs) are uncertain prior to export or collection of information which is not cost free for an individual firm. In this paper, we extend the heterogeneous firm model of Melitz to analyze how an...

This paper proposes a homotopy method for implementing counterfactual experiments in empirical models with multiple equilibria. A key assumption is that the equilibrium selection function does not jump discontinuously between equilibria as we continuously change the structural parameters.

This note combines a dynamic industrial organization model, in which an industry is subject to exogenous processes of market-size and collusion structure, with a consumption-based asset pricing model for the shares in the industry’s firms. Three main findings emerge for our model under the...

It is shown in this paper that there exist cost innovations for which a monopolist has a higher incentive to invest than a social planner. This unveils the limits of the claim, based on Arrow (1959), that a monopoly always has a lower incentive to innovate than a social planner and therefore...

Bundled discounts by pairs of otherwise independent firms play an increasingly important role as a strategic tool in several industries. Given that prices of firms competing for the same consumers are strategic complements, one would expect their discounts levels also to be strategic...
