Effects of corporate tax reform on optimum debt maturity

摘要

This study investigates effects of selecting maturity years on investment decisions. Ceteris paribus an optimum debt maturity (ODM) maximising net present value exists and its change correlates positively with corporate tax rates but negatively with real interest rates, while its relationship with inflation rate is conditional. Furthermore depreciation does not matter at all. A model simulation carried out for seven selected EU countries demonstrates the most significant role of real interest rate for determining ODM in the period of 1981-2004. Yet corporate tax rate will gain in importance since interest and inflation rates are more rapidly converging in the EMU.
