This article explores the possibility of associating firm size vis-à-vis industry size with firm-level R&D led-innovation and the resultant impact(s) on industry level output and price. We consider an oligopolistic industry having one dominant firm and some fringes. Innovation by the dominant...

Artificial intelligence algorithms are increasingly used by firms to set prices. Previous research on pricing algorithms shows that they can exhibit collusive behavior, but it has so far remained an open question whether they can do so in a reasonably short time. I develop a deep reinforcement...

In this paper we consider how the degree of risk aversion, and demand/cost uncertainty, influence competition on oligopolistic markets. Under demand uncertainty, the best response strategies (both quantities and prices) are decreasing in risk aversion, but for cost uncertainty, quantities are...

We develop a model of Cournot competition between capacity-constrained firms that sell a single good to multiple regions. We provide a novel characterization for the unique equilibrium allocation of the good across regions and design an algorithm to compute it. We show that a reduction in...

In a Stackelberg oligopoly with cost asymmetry and possibility of entry, the Stackelberg leader faces a kinked demand curve. For a robust interval of cost of the leader, the equilibrium price is rigid with respect to small changes in demand and costs of active firms

This paper analyzes competition in a two-period differentiated-products duopoly in the presence of both switching costs and network effects. We show that they have opposite implications on the demand side, specially in the first period. While the former reduces demand elasticities, the latter...

Vega-Redondo (1997) showed that imitation leads to the Walrasian outcome in Cournot Oligopoly. We generalize his result to aggregative quasi-submodular games. Examples are the Cournot Oligopoly, Bertrand games with differentiated complementary products, Common-Pool Resource games, Rent-Seeking...

We present a formal model of symmetric n-firm Cournot oligopoly with a heterogeneous population of optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a la Vega-Redondo (1997). Optimizers play a myopic best response to the opponents'...

Two related models of oligopolistic price competition with homogeneous products are presented. These models are based on weaker assumptions about consumer behavior compared to a classical Bertrand model. In both models firms do not necessarily face a discontinuous demand at an equilibrium price...
