Abstract

In “An Investigation of the Extrapolative Determinants of Short-Run Earnings Expectations,” Professor McEnally has presented a wide spectrum of research results dedicated to the following questions: Are short-run earnings estimates extrapolative and to what extent can these earnings estimates be approximated by familiar extrapolation techniques? His thesis is that expected future earnings are in part a function of prior earnings and that there is much to be learned by fitting a series of regressions or other forecasting models to historical data.
