We carefully review the recent Italian reform of business taxation, compare
it with other international experiences and theoretical proposals, and cal
culate its effects on the cost of capital and on the effective average corp
orate tax rate. We argue that the Italian reform is an original attempt to
find a compromise between two conflicting aims, both of which are unavoidab
le in an open economy: the first is to reduce the average rate of taxation
on profits, and the second is to reduce the financial and real distortions
produced by corporate taxation. In assessing the initial evidence in the It
alian case, we argue that too much weight has been given to the latter obje
ctive, and that further reductions in average taxation on profits may be ne
eded.
