We provide a model that explains the following empirical observations: i) private ownership is more efficient than public ownership, ii) privatizations are associated with increases in efficiency and iii) the increase in efficiency predates the privatization. The two key mechanisms explaining...

We propose a model of investments prior to corporate ownership changes. We derive conditions under which the selling of a firm triggers overinvestment by both the seller and the buyer prior to the asset transfer. In a setting with Cournot competition, we show that these incentives can drive the...

This paper investigates price patterns of off-patent pharmaceuticals in Sweden. I show that price dynamics are dependent on the number of competitors in the market. The price patterns follow predictions from a model of dynamic price competition in which the demand for pharmaceuticals...

Intellectual property rights and competition policy are intimately related. In this paper I survey the economic literature analyzing the interaction between intellectual property law and competition law and how the boundary between these two policies is drawn in practice. Recognizing that...

We develop a model of vertical pricing in which an original manufacturer sets wholesale prices in two markets integrated at the distributor level by parallel imports (PI). In this context we show that if competition policy requires uniform wholesale prices across locations it would push retail...

The supply function equilibrium provides a game-theoretic model of strategic bidding in oligopolistic wholesale electricity auctions. This paper presents an intuitive account of current understanding and shows how welfare losses depend on the number of firms in the market and their asymmetry....

This paper presents an empirical test of the anticompetitive effects of joint ownership, by examining the operation of three nuclear plants in Sweden. Since maintenance is the main conduit explaining the variation in output, I formulate a model of intertemporal choice in which firms choose how...

A government wanting to promote an efficient allocation of resources as measured by the total surplus, should strategically delegate to its competition authority a welfare standard with a bias in favour of consumers. A consumer bias means that some welfare increasing mergers will be blocked....
