This paper establishes the existence and uniqueness of an intuitively-refined Markov-Perfect Equilibrium in a richly-specified dynamic duopoly model of entry and exit. We develop an algorithm that computes it very quickly, which makes the model useful for experiments that use many parameter...

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

I develop a dynamic oligopoly model to study the evolution of retail grocery: Grocery chains expand at the expense of independent local stores. Model estimation only requires panel data on store counts and market demand, yet it quantifies the determinants of chain stores' entry and the...

We consider a periodic review joint pricing and inventory control model in which a firm faces both stochastic demand and fluctuating procurement costs. To address procurement cost fluctuation, the firm adopts a dual-sourcing strategy, under which it procures from a spot market with immediate...

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...

While practitioners call for long-term managerial compensation to promote firms’ commitment in environmental, social and governance (ESG) issues, little direct evidence exists on the role managerial incentive horizon plays in firms’ ESG performance. Exploiting two alternative identification...

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...

This paper develops an econometric model of industry dynamics for concentrated markets that can be estimated very quickly from market-level data on demand shifters and the number of producers. We show that the model has an essentially unique symmetric Markov-perfect equilibrium that can be...

Mobility-as-a-Service (MaaS) is based on the notion that consumers and transport providers access a centralized platform for the planning, payment, and management of trips, and combines multiple modes of transportation designed to increase the efficiency of the system. MaaS offers substantial...
