Deregulation of Shopping Hours: The Impact on Independent Retailers and Chain Stores
研究了放松购物时间管制对零售连锁店和独立零售商的影响，发现效率差异决定谁受益：差异小时独立零售商受益，差异大时连锁店受益。
Abstract This paper studies shopping hour decisions by retail chains and independent competitors. We use a Salop‐type model in which retailers compete in prices and shopping hours. Our results depend significantly on efficiency differences between the retail chain and the independent retailer. If the efficiency difference is small, the independent retailer may choose longer shopping hours than the retail chain and may therefore gain from deregulation at the expense of the retail chain. The opposite result emerges when the efficiency difference is large. Then, the retail chain may benefit whereas the independent retailer loses from deregulation.
