本文考虑了与差异化产品的寡头市场横截面上“供需”分析的问题。主要方法是假设需求可以通过离散选择模型来描述，并且价格是由价格设定的公司内源决定的。与以前的一些经验工作相反，这些技术明确允许价格与市场横截面中未观察到的需求因素相关。本文提出了通过“倒转”的市场共享方程来估算，以找到每个商品的隐含平均效用水平。这种方法允许通过传统的仪器变量技术进行估计。
This article considers the problem of ''supply-and-demand'' analysis on a cross section of oligopoly markets with differentiated products. The primary methodology is to assume that demand can be described by a discrete-choice model and that prices are endogenously determined by price-setting firms. In contrast to some previous empirical work, the techniques explicitly allow for the possibility that prices are correlated with unobserved demand factors in the cross section of markets. The article proposes estimation by ''inverting'' the market-share equation to find the implied mean levels of utility for each good. This method allows for estimation by traditional instrumental variables techniques.
