THE EFFECT OF RETAIL FIRM OWNERSHIP ON PRICE EQUILIBRIUM*
用一个简单的线性城市模型，研究了零售企业所有权差异如何导致价格分化，因为不同所有权的零售企业内部化购物外部性的方式不同。
ABSTRACT. This paper examines the effect of retail firm ownership on price equilibrium using a simple linear‐city model. It is shown that price divergence emerges due to the differences in retail firm ownership, because retail firms under different ownership internalize shopping externalities differently. It is also shown that if a commercial center has two specialized retail firms, these stores charge the same markup for different goods at the equilibrium.
