Evolutionary Stability in Asymmetric Oligopoly. A Non-Walrasian Result

Leininger, Wolfgang; Moghadam, Hamed - Rheinisch-Westfälisches Institut für … - 2014

It is a very well-known result that in terms of evolutionary stability the long-run outcome of a Cournot oligopoly …. Contrary to Tanaka (1999) we show that the evolutionarily stable price in an asymmetric Cournot oligopoly needs not equal the … order to transform the game with asymmetric firms into a symmetric oligopoly game and then extend Schaffer’s definition …

Altruism Heterogeneity and Quality Competition Among Healthcare Providers

Kairies-Schwarz, Nadja - Rheinisch-Westfälisches Institut für … - 2014

New empirical evidence shows substantial heterogeneity in the altruism of healthcare providers. Spurred by this evidence, we build a spatial quality competition model with altruism heterogeneity. We find that more altruistic healthcare providers supply relatively higher quality levels and...

The Inefficiency of Market Transparency – A Model with Endogenous Entry

Gu, Yiquan; Hehenkamp, Burkhard - Rheinisch-Westfälisches Institut für … - 2010

Including the entry decision in a Bertrand model with imperfectly informed consumers, we introduce a trade-off at the level of social welfare. On the one hand, market transparency is beneficial when the number of firms is exogenously given. On the other, a higher degree of market transparency...

Knowledge Transfer in Buyer-Supplier Relationships – When It (Not) Occurs

Bönte, Werner; Wiethaus, Lars - Rheinisch-Westfälisches Institut für … - 2005

Abuyer’s technical knowledge may increase the efficiency of its supplier.Suppliers, however, frequently maintain relationships with additional buyers. Knowledge disclosure then bears the risk of benefiting one’s own competitor due to opportunistic knowledge transmission through the common...

A Note on the Excess Entry Theorem in Spatial Models with Elastic Demand

Gu, Yiquan; Wenzel, Tobias - Rheinisch-Westfälisches Institut für … - 2007

This paper revisits the excess entry theorem in spatial models à la Vickrey (1964) and Salop (1979) while relaxing the assumption of inelastic demand. Using a demand function with a constant demand elasticity, we show that the number of firms that enter a market decreases with the degree of...

Product Variety, Price Elasticity of Demand and Fixed Cost in Spatial Models

Gu, Yiquan; Wenzel, Tobias - Rheinisch-Westfälisches Institut für … - 2009

This paper explores the implications of price-dependent demand in spatial models of product differentiation.We introduce consumers with a quasi-linear utility function in the framework of the Salop (1979) model.We show that the so-called excess entry theorem relies critically on the assumption...

Liberalization of Opening Hours with Free Entry

Wenzel, Tobias - Rheinisch-Westfälisches Institut für … - 2007

This paper studies competition in prices and opening hours in a model with free entry. It is shown that under free competition a market failure arises: Entry is excessive and opening hours are under-provided. Restrictions on opening hours aggravate this failure. I analyze the impact of a...

The Recommendation Effect in the Hotelling Game - A New Result for an Old Model

Conze, Maximilian; Kramm, Michael - Rheinisch-Westfälisches Institut für … - 2013

Hotelling’s famous "Principle of Minimum Differentiation" suggests that two firms engaging in spatial competition will decide to locate at the same place. Interpreting spatial competition as modeling product differentiation, firms will thus offer products that are not differentiated and...
