This paper reexamines the benefits of pooling and, in addition, contrasts the performance of
newly proposed heterogeneous estimators. The analysis utilizes a panel data set from 46
American states over the period 1963 to 1992 and a dynamic demand specification for
cigarettes. Also, the forecast performance of the various estimators is compared.
