Company-taxation policies in the Central and East European New Member States (CEE-NMS) have been frequently characterised as tax-cutting strategies in order to attract Foreign Direct Investment (FDI). On the basis of a survey of six empirical studies a median value of the tax-rate elasticities of FDI of -0.22 in CEE-NMS and mediterranean periphery countries is derived. Yet, these tax-rate elasticities probably suffer from a sort of measurement error bias since these studies entirely rely on the host country Statutory tax rate as measure of tax burden. Building on a thorough criticism of FDI as a measure reflecting multinational activity and the Statutory tax rate as a reliable measure of the effective tax burden, 315 effective average bilateral tax rates (BEATR) are calculated for seven home countries and five CEE-NMS for the period 1996-2004, following the approach of Devereux and Griffith (1998). Since our empirical results show substantial differences in the variability of the host country Statutory tax rates and the BEATRs, it is contended that the latter should be used as explanatory variables in empirical studies. / Series: Discussion Papers SFB International Tax Coordination
