We investigate the decision of entry timing and product positions under market size uncertainty with Brownian motion for continuous-time spatial duopoly competition. We show the following results. First, the leader is more likely to increase the degree of product differentiation as volatility...

We study the entry timing and location decisions of two exclusive buyer-supplier relationships in a continuous-time spatial competition model. In each relationship, the firms determine their entry timing and location, and negotiate a wholesale price through Nash bargaining. Then, the downstream...

We investigate the entry timing and location decisions under market-size uncertainty with Brownian motions in a continuous-time spatial competition duopoly model a la d'Aspremont et al. (1979). Under a sequential equilibrium, the threshold of the follower non-monotonically increases in...

We investigate private and social incentives for standardization to ensure market-wide system compatibility in a two-dimensional spatial competition model. We develop a new methodology to analyze competition on a torus and show that there is a fundamental conflict of interest between consumers...

Motivated by the slow diffusion of generic drugs and the increase in prices of brand-name drugs after generic entry, I incorporate consumer learning and consumer heterogeneity into an empirical dynamic oligopoly model. In the model, firms choose prices to maximize their expected total discounted...

This study investigates the impact of the timing of manufacturers' market entry to an online market on the performances of all the firms in a supply chain. It considers a multi-echelon supply chain which consists of two manufacturers, who sell differentiated products and compete with each other,...

This paper develops an econometric model of firm entry, competition, and exit in oligopolistic markets. The model has an essentially unique symmetric Markov-perfect equilibrium, which can be computed very quickly. We show that its primitives are identified from market-level data on the number of...

This paper develops a simple model of firm entry, competition, and exit in oligopolistic markets. It features toughness of competition, sunk entry costs, and market-level demand and cost shocks, but assumes that firms' expected payoffs are identical when entry and survival decisions are made. We...

This paper develops an econometric model of oligopoly dynamics that can be estimated very quickly from market-level observations of demand shifters and the number of producers. We show that the model has an essentially unique symmetric Markov-perfect equilibrium and provide an algorithm that...

This paper examines a dynamic incumbent-entrant framework with stochastic evolution of the (inverse) demand, in which both the optimal timing of the investments and the capacity choices are explicitly considered. We find that the incumbent invests earlier than the entrant and that entry...
