Der vorliegende Beitrag wendet die dynamische Wettbewerbstheorie von Wolfgang Kerber und anderen auf aktuelle Fragen der Wettbewerbspolitik an. Damit zeigt der Beitrag, dass dynamische Wettbewerbstheorien sehr wohl zu konkreten wettbewerbspolitischen Empfehlungen führen und einen wichtigen...

The article is a contribution to the evolving field of competition research. More precisely our paper provides a comprehensive typology of the different ways competitization is and has been studied across different disciplines and research programs. The article goes beyond a classical literature...

In November 2021, the IEA was pleased to hold, in partnership with the Information Technology and Innovation Foundation, a conference on the Meaning of Competition featuring leading commentators and academics in the field.The objective was to reflect, in the 75th anniversary year of Hayek’s...

This study explores the effects of competition on fair trade operations. Specifically, as a benchmark, we first explore a model with one fair trade organization (FTO), i.e., the monopoly FTO. We then consider two competing FTOs, i.e., the duopoly FTOs. These two competing FTOs have the same goal...

In dieser Festschrift für Wolfgang Kerber würdigen Kolleginnen und Kollegen, Wegbegleiter und ehemalige Schüler sein wissenschaftliches Werk und Wirken in den Bereichen Wettbewerbspolitik, Rechtsökonomik sowie weiteren Teilbereichen der Wirtschaftspolitik. Zeitgemäß bilden Beiträge zu...

The paper uses CPS data from 1964 to 1985 to test for the existence of rent-sharing in US tabor markets, Using an unbalanced panel from the manufacturing sector, and random-effects and fixed-effects specifications, the paper finds that changes in wages are explained by movements in lagged levels...

We propose an approximation method for analyzing Ericson and Pakes (1995)-style dynamic models of imperfect competition. We develop a simple algorithm for computing an ``oblivious equilibrium,'' in which each firm is assumed to make decisions based only on its own state and knowledge of the long...

Supporting ecological innovations and economic activities which lead to environmental protection is one of the important challenges to decision-makers. The above is related to the problem of specification of mechanisms resulting in introducing ecological innovations to the economy. The original...

We develop a model of political competition with endogenous turnout and endogenous platforms. Parties trade off incentivizing their supporters to vote and discouraging the supporters of the competing party from voting. We show that the latter objective is particularly pronounced for a party with...

Models of firm conduct are the cornerstone of both theoretical and empirical work in industrial organization. A recent contribution (Berry and Haile, 2014) has suggested the use of exclusion restrictions to test alternative conduct models. We propose a pairwise testing procedure based on this...

Competition authorities and regulatory agencies sometimes impose pricing restrictions on firms with substantial market power - the dominant firms. We analyze the welfare effects of a ban on behaviour-based price discrimination in a two-period setting where the market displays a competitive and a...

We characterize the unique Markov perfect equilibrium of a tug-of-war without exogenous noise, in which players have the opportunity to engage in a sequence of battles in an attempt to win the war. Each battle is an all-pay auction in which the player expending the greater resources wins. In...

In this paper we analyze the structure of contest equilibria with a variable number of individuals. First we analyze a situation where the total prize depends on the number of agents and where every single agent faces opportunity costs of investing in the contest. Second we analyze a situation...

In an environment in which both buyers and sellers can undertake match specific investments, the presence of market competition for matches may solve hold-up and coordination problems generated by the absence of complete contingent contracts. In particular, this paper shows that when matching is...

This article provides an overview of the competitive issues surrounding online platforms. The general theme is that while much has been made of the structural features of online platforms there is little hard evidence that these are durable monopolies. Nonetheless, there are concerns about the...

Friedrich A. von Hayek’s (1899-1992) view of competition as a discovery process is well known but little used. His central thesis is that a competitive pricing system is the most effective way to coordinate economic activity and economise on the information held by market participants in a...

The concept of two-sided markets tries to describe certain characteristics of today's big platforms. Despite attracting a great deal of academic interest, closer inspection shows that the theory suffers from a great deal of ambiguity. This paper attempts to highlight these fundamental...

While in Europe the influence of the »More Economic Approach« has been extensively debated over the last twenty years, a fresh concept called behavioral antitrust was emerging in US competition law. This new approach assumes market actors who are not always rational, have limited will-power,...

The ordoliberal school of competition thought is a distinct linguistic community whose conceptual and semantic influence extended far beyond Germany and eventually shaped the European legal order. Linguistic misunderstandings still impacted the negotiations of the founding European Treaties, but...

The book is intended to be a reference book of Competition Economics for economists, consultants and/or practitioners. It is a review of demand and supply estimation, market structure, merger analysis, damage estimation, welfare loss, abuse of dominance, network effects, and a math and...

Im Sanierungsrecht werden Unternehmen zahlreiche Instrumente zur Verfügung gestellt, die wirtschaftlich zu einer Bevorzugung gegenüber Wettbewerbern führen: Insolvenzgeld, Sonderkündigungsrechte, Vollstreckungsmoratorium, Finanzierungseffekte - Scheitern wird im Wirtschaftsrecht belohnt. Was...

The Resource-Advantage Theory of Competition states that a comparative advantage in resources leads to a competitive advantage in the marketplace. This research aims to expand this theory by including the role of innovation, particularly environmental innovation, as a moderating variable in the...

A model is provided whereby a monopolist firm chooses to price its product at zero. This outcome is shown to be driven by the assumption of `free disposal' alongside selection markets (where prices impact on a firm's costs). Free disposal creates a mass point of consumers whose utility from the...

This article examines the meaning and scope of the notion of anticompetitive effects in EU competition law. It does so by bringing together several strands of the case law (and this across all provisions, namely Articles 101 and 102 TFEU and merger control). The analysis is structured around a...

Competition is at the core of economics, being both a central concept of economic reasoning and a main prerequisite for economic action. Yet, the attempt of a clear definition of competition is challenging as the concept of competition has been used in different historical and disciplinary...

This paper lays down the rudiments of a descriptive theory of competition among the digital tech platforms known as “FANGs” (Facebook, Amazon, Netflix and Google), amidst rising academic and policy polarization over the answer to what seems to be – at least at the formulation level – a...

We consider platform competition in a two-sided market, where the two sides (buyers and sellers) have ex-ante uncertainty and ex- post asymmetric information concerning the value of a new tech- nology. We find that platform competition may lead to a market failure: competition may result in a...

We consider platform competition in a two-sided market, where the two sides (buyers and sellers) have ex-ante uncertainty and ex-post asymmetric information concerning the value of a new technology. We find that platform competition may lead to a market failure: competition may result in a lower...

We examine whether agency contracts, more than traditional wholesale contracts, facilitate collusion among upstream manufacturers. We develop an infinitely repeated game with a monopoly platform and multiple manufacturers, and show that the agency contract does not facilitate upstream collusion....

In price-based (exclusionary) abuse of dominance cases, price-cost tests tend to be the main, if not only, piece of evidence relied upon to conclude whether or not an infringement has taken place. While we consider that this assigns too much weight and relevance to this element of the analysis,...
