Measuring Arbitrage Opportunities
提出最小绩效无效率估计方法，用于衡量套利机会，相比数据包络分析等方法有优势，并用出版业数据验证。
Entrepreneurs respond to opportunities that come in two basic forms: innovation and arbitrage. This article presents a technique called the minimum performance inefficiency (MPI) estimation method that could be used to estimate arbitrage opportunities. The technique has several advantages over the conceptually similar data envelopment analysis (DEA) and other techniques. The authors validate the technique with a well-known data set and illustrate its use based on secondary data from the publishing industry.
