Asymmetric Vertical Integration (2005)
Buehler, Stefan, Schmutzler, Armin
We examine vertical backward integration in a reduced-form model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain...

This paper examines the consequences of introducing mobile number portability (MNP). We show that if the sole effect of introducing MNP is the abolishment of switching costs, MNP unambiguously...
A Further Look at Two-way Network Competition in Telecommunications
This paper develops a simple reduced form model of two-way network competition with linear retail pricing. Using the techniques of supermodular games, it is demonstrated that the most important...
Merge or Fail? The Determinants of Mergers and Bankruptcies in Switzerland, 1995-2000
Stefan Buehler, Christian Kaiser, Franz Jaeger
This paper examines the determinants of mergers and bankruptcies, using firm level data from the Swiss Business Census and the Dun & Bradstreet exit database for Switzerland (1995-2000). Employing...
On The Role of Access Charges Under Network Competition
Stefan Buehler, Armin Schmutzler
We aim to clarify the role of access charges under two-way network competition, employing a reduced-form approach. Retaining the key features of specific network competition models but imposing less...
Stefan Buehler, Armin Schmutzler
We examine the interplay of endogenous vertical integration and costreducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general...
Mergers under Asymmetric Information – Is there a Lemons Problem?
Thomas Borek, Stefan Buehler, Armin Schmutzler
We analyze a Bayesian merger game under two-sided asymmetric information about firm types. We show that the standard prediction of the lemons market model–if any, only low-type firms are...
Competition Policy and Exit Rates: Evidence from Switzerland
Stefan Buehler, Christian Kaiser, Franz Jaeger
This paper provides evidence on the relation between the intensity of product market competition and the probability of exit. We adopt a natural experiment approach towards analyzing the impact of a...
Deregulating Network Industries: Dealing with Price-Quality Tradeoffs
Stefan Buehler, Dennis Gaertner, Daniel Halbheer
This paper examines the e®ects of introducing competition into monopolized network industries on prices and infrastructure quality. Analyzing a model with reduced-form demand, we ¯rst show that...
Downstream Investment in Oligopoly
Stefan Buehler, Armin Schmutzler
We examine cost-reducing investment in vertically-related oligopolies, where firms may be vertically integrated or separated. Analyzing a standard linear Cournot model, we show that: (i) Integrated...
Asymmetric Vertical Integration
Stefan Buehler, Armin Schmutzler
We examine vertical backward integration in a reducedform model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain...
Strategic Outsourcing Revisited
This paper analyzes a sequential game where firms decide about outsourcing the production of a non-specific input good to an imperfectly competitive input market. We apply the taxonomy of business...
This paper examines the consequences of introducing mobile number portability (MNP). As MNP allows consumers to keep their telephone number when switching providers, it reduces consumers’ switching...
Weddings with Uncertain Prospects – Mergers under Asymmetric Information
Thomas Borek, Stefan Buehler, Armin Schmutzler
We provide a framework for analyzing bilateral mergers when there is two-sided asymmetric information about firms’ types. We show that there is always a "no-merger" equilibrium where firms do not...
Estimating Vertical Foreclosure in U.S. Gasoline Supply
We examine the competitive effects of the vertical integration of gasoline refineries and retailers in the U.S. Adapting the first-order condition approach of static oligopoly games to the analysis...
Infrastructure Quality in Deregulated Industries: Is there an Underinvestment Problem?
Stefan Buehler, Armin Schmutzler, Men-Andri Benz
We investigate how various institutional settings affect a network provider’s incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out...
How to Regulate Vertical Market Structure in Network Industries
This paper analyzes the equilibrium outcomes in a network industry under different vertical market structures. In this industry, an upstream monopolist operates a network used as an input to produce...
Quality Provision in Deregulated Industries: The Railtrack Problem
Men-Andri Benz, Stefan Buehler, Armin Schmutzler
This paper studies a network provider's incentives to invest in infrastructure quality. In a simple but general framework, we investigate how various institutional settings affect investment...
Is Swiss Telecommunications a Natural Monopoly? An Evaluation of Empirical Evidence
Based upon time series data published by PTT prior to regulatory reform, this paper investigates whether Swiss telecommunications qualify as a natural monopoly. Employing the subadditivity concept...

On the Geographic and Cultural Determinants of Bankruptcy
Stefan Buehler, Christian Kaiser, Franz Jaeger
This paper examines the role of geography and culture in explaining bankruptcy. We adopt survival analyses to model the bankruptcy risk of a firm, allowing for time-varying covariates. Based on a...
We examine the effects of restructuring electricity markets on capacity investments, retail prices and welfare when demand is uncertain. We study the following market configurations: (i) integrated...
