Measuring the satisfaction of comparison-shoppers

Recently, Foresee Results, a consulting company founded by Professor Claes Fornell from University of Michigan, was engaged into the measurement of the ACSI (American Customer Satisfaction Index) for Shopping.com and eBay.com users.According to ForeSee Results, customer satisfaction could be used to reflect changes in company revenue, stock price, etc. It seems some statistics method like SEC (Structural Equational Modeling) is used to establish the relationship among them.
