摘要：We estimate the elasticity of corporate taxable income with respect to the
effective corporate tax rate on the basis of a pseudo-panel constructed from
corporate tax return micro data for the period 1998-2001, a period which saw the
introduction of a major corporate tax reform in Germany. Endogeneity of the
effective tax rate is controlled for by an instrumental variable approach. Our
instrument for the observed effective corporate tax rate is the counterfactual
effective tax rate a corporation would face in a particular period had there be
no endogenous change of corporate profits. This counterfactual is obtained from
a detailed microsimulation model of the corporate sector based on tax return
micro data. We find a statistically significant and relatively large point
estimate of the average tax base elasticity, which implies that a reduction of
the statutory corporate tax rate would reduce corporate tax receipts less than
proportionally due to income shifting activities. We also find some
statistically weak evidence for the hypothesis that the tax base elasticity is
higher for corporations that may benefit from various forms of tax shields.
