We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic severallayer model of European gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall supply situation ...
In this paper, we discuss the relationship between infrastructure regulation and investment in light of the emerging "security of supply" debate. We approach the subjectby surveying the literature of the past two decades, especially examining the interactions among restructuring, regulation, and investment. The empirical section of this paper relies on case studies of the relationship between the regulatory ...
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, ...
Environmental policies frequently target the ratio of dirty to green output within the same industry. To achieve such targets, the green sector may be subsidized or the dirty sector be taxed. We show that in a monopolistic competition setting, the two policy approaches have different welfare effects, depending on the design of the instrument (ad valorem versus unit instrument) and the initial situation ...
In recent years, CO2 emissions have become the leading basis of assessment for car taxes in most European countries. In July 2009, with a view to pursuing climate policy goals, also Germany began using this factor to assess taxation on cars. The DIW Berlin has carried out a systematic and quantitative comparison of car taxation in Europe.1 The results reveal high tax rates in over ten countries that ...
