We test for the existence of endogenous agglomeration forces, using structural econometric models. After showing generally how to establish the existence of agglomeration forces empirically, we undertake an industry study of the maritime industry in Norway. The results suggest that there are...

We study cartel contracts using data on 18 contract clauses of 109 legal Finnish manufacturing cartels. One third of the clauses relate to raising profits; the others deal with instability through incentive compatibility, cartel organization, or external threats. Cartels use three main...

The notion 'semicollusion' refers to situations where firms collude in one (or several) choice variable(s) and compete in others. For example, firms collude on prices and compete on advertising. Although the notion 'semicollusion' is not so often used explicitly, it turns out that the topic is...

The purpose of this paper is to test the nature of competition concerning price and capacity setting in the Norwegian airline industry after its deregulation in 1994. Did the two airlines, SAS and Braathens, compete on prices and capacities (competition), collude on prices and capacities...

This paper examines Norwegian gasoline pump prices using daily station-specific observations from March 2003 to March 2006. Whereas studies that have analysed similar price cyclees in other countriees find support for the Edgeworth cycle theory (Maskin and Tirole, 1988), we demonstrate that...

This paper examines Norwegian gasoline pump prices using daily station-specific observations from March 2003 to March 2006. Whereas studies that have analyzed similar price cycles in other countries find support for the Edgeworth cycle theory (Maskin and Tirole, 1988), we demonstrate that...

We test for internal and external economies of scale in European manufacturing, employing a more disaggregated data set than has been used in earlier analyses. We aim to separate externalities from common business cycle effects. Fifteen European manufacturing industries in Germany, France, the...

In this paper we apply the Bresnahan-Lau (1982) model to test for market power in the European distribution of salmon. In this particular setting, the model also incorporates a test of whether dumping takes place over time. Utilising data at the import level, derived demand equations are...
