The most common reason for scrapping a wind turbine in Denmark is to make room for a newer turbine. The decision to scrap a wind turbine is then highly dependent on an opportunity cost that comes from the interaction of scarce land resources, technological change and changes in subsidy policy....

We review the recent empirical research concerning market power on the Nordic wholesale market for electricity, Nord Pool. There is no evidence of blatant and systematic exploitation of system level market power on Nord Pool. However, generation companies seem from time to time able to take...

We analyse in a theoretical framework the link between real-time and day-ahead market performance in a hydro-based and imperfectly competitive wholesale electricity market. Theoretical predictions of the model are tested on data from the Nordic power exchange, Nord Pool Spot (NPS).We reject the...

The capacity of the transmission network determines the extent of integration of a multinational energy market. Cross-border externalities render coordination of network maintenance and investments across countries valuable. Is it then optimal to collect powers in the hands of a single...

An important challenge facing many deregulated electricity markets is dealing with the increasing penetration of intermittent generation. Simulation studies have pointed to the advantages of trading closer to real-time with large amounts of intermittent generation. Using Danish data, I show...

What factors determine national differences in the size and industry distribution of employment? This study stresses the role of business taxation, employment security laws, credit market policies, wage-setting institutions and the size of the public sector. We characterize these aspects of the...

Attention is called to a little explored scarce resource, termed 'economic competence', which combines features of human capital and bounded rationality, and causes a singularity in resource-allocation in society. The performance of each economy is shown to strongly depend on how this resource...

In this paper it is argued that the size distribution of firms may largely be determined by institutional factors. This hypothesis is tested in an exploratory fashion by studying the evolution of the size distribution of firms over time in Sweden for a period spanning from teh late 1960s to the...
