This paper investigates the effect of economic integration on the ability of firms to maintain a collusive understanding about staying out of each other's markets. The paper distinguishes among different types of trade costs: ad valorem, unit, fixed. It is shown that for a sufficient reduction of ad valorem trade costs, a cartel supported by collusion on either quantities or prices will be weakened, ...
This paper compares the outcomes of corporate self-regulation and traditional ex-ante regulation of network access to monopolistic bottlenecks. In the model of self-regulation, the domestic gas supplier and network owner and the monopsonistic gas customer fix quantities and the network access price, whereas the competitive fringe of foreign gas producers (third party) and the household customers are ...
Environmental taxation very often comprises special provisions for parts of the business sector in order to attenuate effects on competitiveness of emissionintensive activities. This paper discusses motives, alternative designs and criteria for the evaluation of such safeguards and analyzes if such provisions can reconcile environmental and economicobjectives. It looks at theoretical aspects as well ...
Environmental policies frequently target the ratio of dirty to green output within the same industry. To achieve such targets the green sector may be subsidised or the dirty sector be taxed. This paper shows that in a monopolistic competition setting the two policy instruments have different welfare effects. For a strong green policy (a severe reduction of the dirty sector) a tax is the dominant instrument. ...
We examine the degree of natural gas market integration in Europe, North America and Japan, between the mid 1990's and 2002. The relationship between the international gas marker prices, and their relation to the oil price, are investigated through principal component analysis and Johansen likelihood-based procedures. Both of them show a high level of integration within the European/Japanese and North ...
Innovation is increasingly seen as a collective action which involves many different actors operating in a cluster context. These clusters are usually conceived as local agglomerations. In this paper it will be argued that they are an important tool to study innovation, but the globalisation of companies and markets and the specific requirements of innovation processes require the expansion of cluster ...
Recently the software industry has experienced fundamental changes in market structure through the entry of open source competitors, e.g. Linux's entry into the operating systems market. In a simple model we examine the effects of such a change in market structure from monopoly to duopoly under the assumption that software producers compete in technology rather than price or quantities. The model includes ...
