Under de senaste åren har ett stort antal svenska företag övergått i utländsk ägo eller fusionerats med utländska företag. Samtidigt har den utländska ägarandelen på börsen ökat snabbt. Är detta endast en naturlig del av den pågående internationaliseringen eller förstärks...

The Pareto dominance relation is shown to be the unique nontrivial partial order on the set of finite-dimensional real vectors satisfying a number of intuitive properties.

This paper investigates the relationship between happiness (utility) and a host of socio-economic variables. The data set consists of a random sample of over 5,000 individuals from the Swedish adult population. Happiness is measured by a three-point categorical measure of overall happiness (not...

It has been argued that having a contract market before the spot market enhances competition (Allaz and Vila, 1993). Taking into account the repeated nature of electricity markets, we check the robustness of the argument that the access to contract markets reduces the market power of generators....

Two firms produce different qualities at possibly different, constant marginal costs. They compete in quantities on a market where buyers only observe the average quality supplied. The model is a generalization of the standard Cournot duopoly, which corresponds to the special case where the two...

We study an asymmetric information model in which two firms are active on a market where buyers only observe the average quality supplied. Quantities and cost structures are exogenously given and firms compete in quality. Before choosing their qualities, they bargain over a perfectly enforcable...

The literature on deregulated electricity markets generally assumes available capacities to be given. In contrast, this paper studies a model where firms precommit to capacity levels before competing in a uniform price auction. The analysis sheds light on recent empirical findings that firms use...

In the original model of pure price competition, due to Joseph Bertrand (1883), firms have linear cost functions. For any number of identical such price-setting firms, this results in the perfectly competitive outcome; the equilibrium price equal the firms' (constant) marginal cost. This paper...
