To Pool or Not to Pool: Homogeneous Versus Heterogeneous Estimators Applied to Cigarette Demand
2000
Review of Economics and Statistics
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.
