A Factor Analytical Approach to Price Discovery
针对现有价格发现方法在市场数量多时失效、需识别约束且难以统计推断的问题，提出一种利用数据截面变异的因子分析方法，无需识别约束且便于推断。
Abstract Existing econometric approaches for studying price discovery presume that the number of markets are small, and their properties become suspect when this restriction is not met. They also require making identifying restrictions and are in many cases not suitable for statistical inference. The current paper takes these shortcomings as a starting point to develop a factor analytical approach that makes use of the cross‐sectional variation of the data, yet is very user‐friendly in that it does not involve any identifying restrictions or obstacles to inference.
