Preliminary version

Electricity markets are moving through integration around the world. However, our understanding of those markets is still limited. I characterize the Bertrand equilibrium in a discriminatory-price electricity auction when suppliers submit a single offer price for their entire production capacity and they face transmission constraints and linear tariffs for the injection of electricity into the grid. With point of connection tariffs, which are used in the majority of the European countries, suppliers pay a tariff for the total electricity injected into the grid. In contrast, with transmission tariffs, suppliers only pay a tariff for the electricity sold in the other market. Transmission tariffs outperform point of connection tariffs by maximizing consumers' welfare and transmission efficiency. The consequences of an increase in transmission capacity differ considerably depending on the tariff. If the transmission tariffs are zero, an increase in transmission capacity is pro-competitive. In contrast, if the transmission tariffs are positive, an increase in transmission capacity is pro-competitive only when the transmission capacity is low.

Integrating Immigrants into the Nordic Labour Markets

An Overall Perspective


Denmark, Finland, Norway and Sweden face similar problems of integrating large groups of immigrants, especially low-educated ones from outside the EU, into their labour markets. In this volume, edited by Lars Calmfors, IFN, and Nora Sánchez Gassen in cooperation with researchers from across the Nordic Region analyse how labour market integration of immigrants can be promoted.
