This paper studies competition in small, concentrated and inter- related markets. Our data set consists of price information fron 543 driving schools in 250 local markets in sweden, which gives a large sample to test hypotheses on how market structure influences competition. The results show...

This paper analyzes a finite horizon, sequential move pricing duopoly, restricting attention to Markov-strategies. The solution yields stationary patterns, independent of initial conditions, where the reaction-functions follow cycles of three periods. The market price never settles down, and is...

We study the choice of drug for the treatment of high blood pressure (hypertension) in Sweden between 1988-1994. During this time period calcium antagonists and ACE-inhibitors increased their market shares at the expense of the older drugs diuretics and beta-blockers. We use a prescription micro...

The central prediction of the Aghion et al. (2005) model is an inverted U-shaped relation between innovation and competition. The model is built on the assumption of a product market and has not yet been empirically tested on service-sector firms. Using detailed firm-level data, we find the...

The pattern of trade between nations is well understood, but much less is known about firm level determinants to export: why do some firms start to export while others continue to produce for the domestic market? One reason for different firm strategies could be that the fixed costs for export...

There has been a revival of interest in small scale industries and their linkages with a nation's institutional arrangements, among both academicians and policy makers. Extending the definition of institutions to include formal and informal rules, this paper attempts to identify these lingages...

While many studies have documented deviations from the Law of One Price in international settings, evidence is scarce on the extent to which consumers take advantage of price differentials and engage in cross border shopping. We use data from 287 Swedish municipalities to estimate how responsive...
