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...

This paper examines if international trade can reduce total welfare in an international oligopoly with differentiated goods. We show that welfare is a U-shaped function in the transport cost as long as trade occurs in equilibrium. With a Cournot duopoly trade can reduce welfare compared to...

Two-way trade in (almost) homogenous products has ambiguous welfare effects if entry is restricted. We examine Swedish imports of bottled water to investigate whether transport cost losses from trade outweigh the partial equilibrium gains from trade (stronger competition and more brands to...

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 report, commissioned by Sveriges Riksbank, examines the role of currency denomination in international trade transactions. It is divided in two parts. The first part consists of a survey of the price setting and payment practices of a large sample of Swedish exporting firms. The second part...

What is the impact of the increasing dominance of conventional firms in e-commerce? We use a simple model to show that retailers who only sell through Internet have lower on-line prices than retailers who also sell through conventional stores. This proposition is firmly supported by our...

Does the common currency promote goods market integration within the EMU? We argue that such an effect is likely, but that the mechanism typically proposed - lover costs of arbitrage because of increased price transparency - is likely to be of minor importance. Instead we sketch a duopoly model...

How does cost pass-through to prices depend on the set of products a multiproduct firm owns? Using a structural demand model for the Swedish beer market, we simulate equilibrium cost pass-through for varying counterfactual ownership patterns. We find that a firm with a larger number of products...

Average profits of a price taker are increasing in the variability of the output price (Oi, 1961). We show that, for the same reason, average profits of the price taker are increasing in the variability of the price of inputs. We proceed to establish that the same holds for a firm with a...

This paper examines the relation between prices in conventional stores and on the Internet. Main results from the theoretical analysis are i) we expect a discrete fall in prices in conventional stores as the share of the population with access to Internet reaches a critical level, ii) the...
