Franchise Contract Regulations and Local Market Structure
研究美国各州限制特许人终止合同的特许经营法规对市场结构的影响，发现法规实施导致快餐业平均县区门店数量减少4-5%，并增加市场集中度。
Many US states have regulations that restrict the ability of franchisors to terminate franchise contracts. We estimate the economic effects of these regulations with a focus on how they impact market structure. Using data from the quick-service restaurant industry, we find that implementing franchise regulations results in 4–5 percent fewer establishments in the average county. Our results imply that franchise regulation leads to increased concentration in a large number of markets, as the number of counties in the bottom quartile of concentration would increase by between 12 percent and 15 percent with regulation.
