摘要：
Billings and Jennings (2011) develop a new measure of stock price sensitivity to earnings called anticipated information content (AIC). The main difference between an AIC and an earnings response coefficient (ERC) is that AICs measure expected rather than actual sensitivity. I evaluate the AIC's potential usefulness in future research, and conclude that AICs have several disadvantages relative to ERCs but might be useful in rare circumstances. Estimates of AICs contain considerable measurement error and fail a primary test of construct validity when left uncorrected. I outline a method for correcting two of the three sources of measurement error, which can be used by researchers interested in pursuing work on AICs. The method may have uses beyond computing AICs because it yields a prediction of the unsigned change in stock price during a scheduled event window.
