Abstract
Specifies a general functional form suggested by Zarembka (1974) for the study of interstate migration in USA and uses the maximum likelihood method suggested by Box and Cox (1964) to estimate the parameters in the general form. The empirical results obtained from alternative functional forms are presented and compared. The validity of linear and log-linear specifications are examined along with other functional forms commonly used in econometric studies. A general functional form and the estimation procedures are introduced. -Authors
