"Against the background of increased globalization statutory corporate tax rates have shown a clear downward trend over the last two decades. The sharp decline in these rates was accompanied by substantial tax base broadening and a comparable reduction in personal income tax rates only until the early 1990s. This suggests that corporate tax competition is of increasing importance. So far corporate tax revenues remain fairly stable. But an analysis of corporate taxation in the context of the overall tax systems shows that a substantial shift towards value-added taxes has taken place. While the trends so far have been driven by smaller European countries, recent tax reforms indicate that increasing tax competition is inducing a shift towards consumption taxes even for larger economies."

"This paper explores the economic consequences of proposed EU reforms for a common consolidated corporate tax base. The reforms replace separate accounting with formula apportionment as a way to allocate corporate tax bases across countries. To assess the economic implications, we use a numerical computable general equilibrium (CGE) model for Europe. It encompasses several decision margins of firms such as marginal investment, FDI decisions, and multinational profit shifting. The simulations suggest that consolidation does not yield substantial welfare gains for Europe. The variation of effects across countries is large and depends on the choice of the apportionment formula. Consolidation with formula apportionment does not weaken incentives for tax competition. Tax competition instead offers a rationale for rate harmonization, in addition to base harmonization."
