摘要:In this paper, we consider optimal tax enforcement policy in the presence of pro.t
shifting towards tax havens. We show that, under separate accounting, tax enforce-
ment levels may be too high due to negative .scal externalities. In contrast, under
formula apportionment, tax enforcement is likely to be too low due to positive ex-
ternalities of tax enforcement. Our results challenge recent contributions arguing
that, under formula apportionment, there is a tendency towards ine¢ ciently high
levels of (e¤ective) tax rates.
