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...

In this paper we use newly compiled top income share data to estimate common breaks and trends across countries over the twentieth century. By using the most re-cent structural breaks techniques, our approach both confirms previous notions and offers new insights. In particular, the division...

We identify pertinent institutions governing the structure of payoffs with regard to female career progression. Drawing on recent insights in behavioral economics, we hypothesize that interac-tions between psychological mechanisms and the institutional setup may be important determinants of...

The various form of pattern bargaining with manufacturing, as representative of the tradables sector, deciding the norm for wage increases in the Nordic countries are reviewed. This form of bargaining has been consistent with strong international competitiveness and has widespread support among...

Horizontal shifts in bid curves observed in wholesale electricity markets are consistent with Cournot competition. Quantity competition reduces the informational requirements associated with evaluating market performance because the markups of all producers then depend on the same inverse...

The world's first multinational electricity market was formed with the creation of the Nordic power exchange, Nord Pool. We analyze the incentives to undertake transmission network investment in the context of the liberalized Nordic electricity market. Welfare improving investment in a...

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....
