It is an open question in antitrust economics whether allowing dominant firms to acquire smaller rivals is ultimately helpful or harmful to the long run rate of innovation and therefore long-term consumer welfare. I develop a framework to study this question in a dynamic oligopoly model where firms endogenously engage in investment, entry, exit and mergers. Firms produce vertically differentiated goods, compete by innovating on product quality, and can acquire rival firms to gain market power… Expand
Big Tech mergers: Innovation, competition for the market, and the acquisition of emerging competitors
Abstract There is broad concern that merger policy toward Big Tech has been too lenient. Big Tech typically operates in markets characterized by innovation-driven “competition for the market.” I showExpand
How Do Start-up Acquisitions Affect the Direction of Innovation?
A start-up engages in an investment portfolio problem by choosing how much to invest in a ''rival'' project, which threatens the position of an existing incumbent, and a "non-rival'' project.Expand

Abstract Resource constraints have a vertical influence on a firm's competition and it is important to address the issue of horizontal mergers with scarce resources. This article highlights theExpand
Optimal Exit Policy with Uncertain Demand
Entrants often need to make considerable sunk investments with highly uncertain returns. The option to exit if returns are low reduces investment risks and stimulates innovation. We examine theExpand

Competition and product innovation in dynamic oligopoly
We investigate the relationship between competition and innovation using a dynamic oligopoly model that endogenizes both the long-run innovation rate and market structure. We use the model to examineExpand
Horizontal mergers and product innovation
We set up a stylized oligopoly model of uncertain product innovation to analyze the effects of a merger on innovation incentives and on consumer surplus. The model incorporates two competitiveExpand
Market structure, innovation and vertical product differentiation
Abstract We reassess Arrow's (1962) [Economic Welfare and the Allocation of Resources for Invention, in NBER, The Rate and Direction of Innovative Activity (Princeton University Press, Princeton NJ)]Expand
Innovation by Entrants and Incumbents
TLDR
The model is extended by allowing incumbents to undertake innovations to improve their products, while entrants engage in more "radical" innovations to replace incumbents, and generates a non-degenerate equilibrium firm size distribution. Expand
Mergers and Innovation
Merger review is the most active area of U.S. antitrust policy. It is now widely believed that merger policy must move beyond its traditional focus on short-run, price and output effects to accountExpand

The effect of competition on innovation incentives has been a controversial subject in economics since Joseph Schumpeter advanced the theory that competitive markets are not necessarily the mostExpand
Internal versus External Growth in Industries with Scale Economies: A Computational Model of Optimal Merger Policy
We study merger policy in a dynamic computational model in which firms can reduce costs through investment or through mergers. Firms invest or propose mergers according to the profitability of theseExpand
A dynamic analysis of consolidation in the broadcast television industry
This paper estimates a dynamic oligopoly model in order to separately identify the demand-side and cost-side advantages of consolidation in the broadcast television industry. I exploit an exogenousExpand
Mergers, Innovation, and Entry-Exit Dynamics: Consolidation of the Hard Disk Drive Industry, 1996-2016
How far should an industry be allowed to consolidate when competition and innovation are endogenous? We extend Rust's (1987) framework to incorporate a stochastically alternating-move game of dynamicExpand
A Dynamic Model of Endogenous Horizonal Mergers
I develop a dynamic model of mergers, where mergers, investment, entry, and exit are endogenous variables rationally chosen by firms to maximize expected future profits. This model differs fromExpand
