We use a dynamic oligopoly model of entry and exit to evaluate how entry regulations affect profitability and market structure in retail. The model incorporates demand and store-level heterogeneity. Based on unique data for all retail food stores in Sweden, we find that the average entry costs...

The basic principle governing the development of the accounting framework is the choice of appropriate comparators. Firstly, when measuring contributions to job creation, we should focus on just job creating firms, otherwise we are summing over contributions from firms with positive, zero, and...

In this paper, we argue that fundamental reforms of the Swedish business sector can explain the remarkable productivity and employment growth that followed the deep economic crisis in Sweden in the early 1990s. In the 1970s and 1980s, Sweden had one of the most regulated business sectors in the...

We use a dynamic oligopoly model of entry and exit with store-type differentiation to evaluate how entry regulations affect profitability, market structure and welfare. Based on unique data for all retail food stores in Sweden, we estimate demand, recover variable profits, and estimate entry...

In this paper, we study a new channel to explain firms' price setting behavior. We propose that uncertainty about factor prices has a positive effect on markups. We show theoretically that firms with higher shares of inputs with volatile prices set higher markups. We use the Bartik shift-share...

This paper estimates a dynamic model of store adjustments in product variety that considers multiproduct service technology to evaluate the impact of entry regulations on variety and long-run profits in Swedish retail. Using rich data on stores and product categories, we find that more liberal...

It is frequently argued that policymakers should target high-tech firms, i.e., firms with high R&D intensity, because such firms are considered more innovative and therefore potential fast-growers. This argument relies on the assumption that the association among high-tech status, innovativeness...

The policy debate in recent years has increasingly focused on issues concerning size distribution of firms and employment. It is often claimed that we are approaching a new economic era where large enterprises have lost their importance in developed economies. This raises the question of what we...

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....
