我们考虑了美国办公用品超市的价格和市场结构之间的关系，这是联邦贸易委员会反对斯台普斯和Office Depot合并的核心。由于标准回归中的潜在偏差，我们采用了两阶段的方法，其中内生市场结构模型为第二阶段价格回归提供了校正项。使用一个横截面的数据，市场结构和斯台普斯的价格，我们发现，排除校正项大大扭曲了竞争对手的重要性，两阶段模型产生更强的价格和市场结构变量之间的负相关关系。
We consider the relationship between prices and market structure for office supply superstores in the U.S. which was central to the Federal Trade Commission's opposition to the merger of Staples and Office Depot. Due to potential biases in a standard regression, we employ a two-stage approach in which a model of endogenous market structure provides correction terms for a second stage price regression. Using a cross-section of data on market structures and Staples' prices, we find that excluding the correction term substantially distorts the importance of competitors as the two-stage model yields stronger negative relationships between prices and market structure variables.
