This report studies the importance of efficiency gains from horizontal mergers. A general theme throughout this report is that efficiency gains, and their pass-on to consumers, may vary substantially from merger to merger. For this reason it seems appropriate to reconsider current practice in...

Quantifying possible inefficiencies stemming from regulation is important to both policymakers and researchers. We use a dynamic structural model to evaluate the role of local market entry regulations in the productivity of retail trade. Our model is flexible with respect to how local market...

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...

This paper explores the role of retailers as an urban amenity. Using data for Swedish rural and city municipalities for 2002–2008, ‘accessibility to shops’ measures are constructed for the shops in the municipalities and in the hosting regions separately to examine the relationship between...

Entry of large ("big-box") stores along with a drastic fall in the number of stores are striking trends in retail. We use a dynamic model to measure the impact of large entrants on productivity, allowing for a controlled productivity process and accounting for prices, local markets, and the...

This paper investigates the determinants of the productivity of independent retail stores in Sweden by focusing on the impact of market size and regional hierarchy while controlling for several store and employee characteristics over time. The analysis utilizes Swedish store-level data for the...
