The impact of intermediary remuneration in differentiated insurance markets
Hofmann, Annette; Nell, Martin - 2008
This article deals with the impact of intermediaries on insurance market transparency and performance. In a market exhibiting product differentiation and coexistence of perfectly and imperfectly informed consumers, competition among insurers leads to non-existence of a pure-strategy market...

Intermediation by heterogeneous oligopolists
Morasch, Karl - Fakultät für Wirtschafts- und … - 2010
In his book on 'Market Microstructure' Spulber presented some strange results with respect to the impact of the substitutability parameter in an intermediation model with differentiated products and inputs. Intuitively, effects in the product and the input market should be similar: if firms...

Simulation and prosecution of a cartel with endogenous cartel formation
Paha, Johannes - 2010
In many cases, collusive agreements are formed by asymmetric firms and include only a subset of the firms active in the cartelized industry. This paper endogenizes the process of cartel formation in a numeric simulation model where firms differ in marginal costs and production technologies. The...

Bertrand and price-taking equilibria in markets with product differentiation
Coloma, Germán - 2008
In this paper we show that a homogeneous-product market with multiple Bertrand equilibria becomes a market with a single Bertrand equilibrium when we introduce a small degree of product differentiation. When differentiation tends to zero, that Bertrand equilibrium converges to the unique...

A Model of Vertical Oligopolistic Competition
Reisinger, Markus; Schnitzer, Monika - 2008
This paper develops a model of successive oligopolies with endogenous market entry, allowing for varying degrees of product differentiation and entry costs in both markets. Our analysis shows that the downstream conditions dominate the overall profitability of the two-tier structure while the...

Vertical differentiation and collusion : cannibalization or proliferation?
Gabszewicz, Jean Jaskold; Marini, Marco A.; Tarola, Ornella - 2016
In this paper, we tackle the dilemma of pruning versus proliferation in a vertically differentiated oligopoly under the assumption that some firms collude and control both the range of variants for sale and their corresponding prices, likewise a multiproduct firm. We analyse whether pruning...

Collusive agreements in vertically differentiated markets
Marini, Marco A. - 2017
This paper introduces a number of game-theoretic tools to model collusive agreements among firms in vertically differentiated markets. I firstly review some classical literature on collusion between two firms producing goods of exogenous different qualities. I then extend the analysis to a...
