The economic effects of environmental taxes depend on the market structure. Under imperfect competition with free entry and exit, environmental taxes have an impact on economies of scale by changing the number and size of firms. Whether economies of scale rise or fall in a particular industry...

This paper discusses how ICT and emerging electronic commerce in consumer products influence the relative efficiency in production of households and firms, resulting in changes in the division of tasks between these two types of agents. Increased information and competence of households, in...

The paper analyzes the contemporary organizational restructuring of production and work within firms. We emphasize the shift from a "Tayloristic" organization of work (characterized by significant specialization by tasks) to a "holistic" organization (featuring job rotation, integration of tasks...

This paper studies energy bias in technical change. For this purpose, we develop a computable general equilibrium model that builds on endogenous growth models. The model explicitly captures links between energy, the rate and direction of technical change, and the economy. We derive the...

This paper studies implications of uncertainty about the arrival date of a competitive CO2 backstop technology for the design of cost-effective CO2 emission trading schemes. For this purpose, we develop a dynamic general equilibrium model that captures empirical links between CO2 emissions...

This paper studies energy bias in technical change. For this purpose, we develop a computable general equilibrium model that builds on endogenous growth models. The model explicitly captures links between energy, the rate and direction of technical change, and the economy. We derive the...

The paper examines of the division of labor within firms. It provides an explanation of the pervasive observed changes in work organisation away from the traditional functional departments and towards multi-tasking and job rotation. Whereas the exsisting literature on the division of labour...

Recent developments in society have generated misalignment between the welfare state and socio-economic conditions and preferences. This paper emphasis developments in the labor market and the structure, stability and preferences of the family, as well as macroeconomic changes. The latter...
