本文的目的是研究大型超市进入某一特定地点对价格的影响。我们使用了智利15个城市1998：I-2004：IV期间的数据。我们修正了潜在的同时性问题，因为进入可能是对价格差异的反应。我们发现，一家大型超市进入一个给定的城市，会使当地市场的相对价格下降7-11%。最有趣的是，我们还发现，这种影响的一部分发生在超市真正开业的前一年。
The purpose of this paper is to investigate the effect on prices of the entry of a large supermarket into a given location. We use a panel with data from fifteen cities in Chile for the period 1998:I–2004:IV. We correct for the potential simultaneity problem derived from the fact that entry can be a response to price differentials. We find that the entry of a hypermarket to a given city reduces relative prices in that local market by 7–11%. Most interestingly, we also find that part of this effect takes place the year before the supermarket actually opens for business.
