• Estimating Market Power in the Swiss Petrol Retailing Industry - a New Empirical Industrial Organisation Approach

Several competition authorities have accused petrol retailers of engaging in collusive conduct, which results in alleged "excessive" prices as well as simultaneous price setting across filling stations. However, petrol retailers must exert a substantial amount of market power if they are to dampen competition. Therefore, we propose a method within the spirit of the New-Empirical-Industrial-Organisation, which allows estimating market power held by petrol retailers in terms of a conduct parameter. Based on data for Switzerland, our empirical results suggest a low level of market power held by Swiss petrol retailers.

• The Labour Market Effects of Outsourcing Parts and Components: A Simple Model with Cournot Competition

This paper analyses a partial equilibrium outsourcing model with Cournot competition in intermediate good production. Final production is located in Western Europe, whereas the intermediate good can be manufactured by a Western (outsourcing) or Eastern European supplier (offshore outsourcing). The paper asks the question how changes in production costs, in particular wages, affect labor input in the two regions in the presence of Cournot competition. The main results are: higher production costs in one region reduce intermediate good production in both regions leading to a substitution effect between high- and low-skilled labor intensive inputs rather than between Eastern and Western low-skilled labor intensive inputs. The sensitivity of outsourcing activities to production cost changes...
