The Effects of Entry Regulation on Oligopolistic Interaction: The Uruguayan Banking Sector
提出一种检验寡头垄断模型的方法，并分析准入限制对市场行为的影响。以乌拉圭银行业为例，发现放松法律准入壁垒降低了领先企业间的寡头竞争程度。
This article develops a methodology to test alternative oligopoly models and to analyze the effects of entry restrictions on conduct. This methodology is applied to the Uruguayan banking sector, whose legal entry barriers were significantly relaxed during the late 1970s. The results are consistent with a von Stackelberg type of industry where the degree of oligopolistic interaction among the leading firms is reduced as a consequence of the relaxation of the legal entry barriers.
