We characterize the equilibrium behavior in a broad class of competition models in which the competing firms' market shares are given by an attraction model, and the aggregate sales in the industry depend on the aggregate attraction value according to a general function. Each firm's revenues and...

This paper develops a tractable model for the computational and empirical analysis of infinite-horizon oligopoly dynamics. It features aggregate demand uncertainty, sunk entry costs, stochastic idiosyncratic technological progress, and irreversible exit. We develop an algorithm for computing a...

Problem Definition: Thanks to the ubiquity of social media and the new business model of live-streaming e-commerce, online retailing has recently embraced increasing interactions among customers. Such interactions give rise to strong network effects, i.e., customers are attracted to purchase the...

Around the start of this new millennium, scholars in the operations management/operations research field started to make important contributions to the study of price competition models. In this tutorial, we review these contributions, and partition them into five broad areas. Most of the...

We analyze a general market for an industry of competing service facilities. Firms differentiate themselves by their price levels and the waiting time their customers' experience, as well as different attributes not determined directly through competition. Our model therefore assumes that the...
