We study communication in a static Cournot duopoly model under the assumption that the firms have unverifiable private information about their costs. We show that cheap talk between the firms cannot transmit any information. However, if the firms can communicate through a third party,...

We study a strategic model of dynamic trading where agents are asymmetrically informed over common value sources of uncertainty. There is a continuum of buyers and a finite number n of sellers. All buyers are uninformed, while at least one seller is privately informed about the true state of the...

In a two-stage R&D game of process innovation, we investigate the effect of exogenously changing R&D spillovers and market concentration on the equilibrium level of effective cost reduction, total output, profits and social welfare. Interpreting spillover as a measure of patent protection, we...

We show that if limit orders are required to vary smoothly, then strategic (Nash) equilibria of the double auction mechanism yield competitive (Walras) allocations. It is not necessary to have competitors on any side of any market: smooth trading is a substitute for price wars. In particular,...

We study intra-individual behavioral heterogeneity in an experimental Cournot oligopoly. Previous empirical results in this setting have demonstrated convergence to competitive outcomes, in agreement with theoretical predictions assuming that players imitate successful opponents. We postulate...

We show that economic decisions in strategic settings are co-determined by multiple behavioral rules. A simple model of intra-individual behavioral heterogeneity predicts testable differences depending on whether rules share a common prescription (alignment) or not (conflict), a classification...

In this paper, we study, how social relations among the firm owners, employees influence their decision to form R&D collaborations with each other. We consider an oligopoly market set-up with n homogeneous firms. Each firm has a representative individual (owner/manager). We examine, how...

Consider an oligopolistic industry composed of two groups (or populations) of firms, the low cost firms and the high cost firms. The firms produce a homogeneous good. I study the finite population evolutionarily stable strategy defined by Schaffer (1988), and the long run equilibrium in the...

A standard Ak-model of endogenous growth has been extended to allow for an intertemporal conflict between capitalists and workers. For the dynamic game thus obtained, an equilibrium solution in feedback Nash (Markovian) strategies have been computed. However, many equilibria in trigger...
