The purpose of this paper is to investigate whether trade policy always switches from export subsidy to export tax if firms engage in Bertrand competition instead of Cournot competitition with trade between two countries.

The purpose of this paper is to analyze the role of anenergy tax on technical improvements and on prices ofconsumer durables induced by strategic competition inenergy efficiency. If the gasoline tax is raised thisdoes in principle not affect the producers of carsbecause the motorist pays for it...

Germany has committed itself to reducing its carbon emissions by 25 percent in 2005 as compared to 1990 emission levels. To achieve this goal, the government has recently launched an environmental tax reform which entails a continuous increase in energy taxes in conjunction with a...

Division of labor, outsourcing in manufacturing and just-in-time production require the provision of a good and sufficient road infrastructure system. The society is used to mobility, preference for it even increases, and the full benefit of competition can only be realized if special distances...

In Europe traffic congestions make it impossible to estimate travel time. The increasing number of cars calls for a transportation policy towards an improved efficiency of the transportation system. However, extending road infrastructure to reduce the congestion externality implies another type...

This paper presents an empirical study of productivity comparison between Japan and Germany with focus on the R&D and infrastructure. By using time-series datasets from auto vehicle industry and electronic engineering industry, the study shows the reversal of productivity advantage from Germany...

The purpose of this paper is to introduce a modification of a standard four input production process where energy is used in an inefficient way due to partly unnecessary waste of energy. In this production process, R&D investment is an additional input in order to improve energy efficiency. It...

The objective of our approach is to develop a model which captures horizontal product differentiation under environmental awareness, product innovation under network effects, and price competition whereby environmentally friendly products are costlier to produce. As an example, we refer to...

The paper addresses the problem of entry barriers for a new technology – hydrogen powered cars or cars with fuel cell engines – if the network of its filling stations is missing or thin. We use Hotelling's model of product differentiation to characterize a situation where an incumbent firm...
