This paper analyzes the switch from Separate Accounting to Formula Apportionment in a dynamic framework. The model features both purely domestic corporations and a domestic multinational which invests at home and abroad as well as a purely foreign corporation and a foreign multinational which...

This paper analyzes tax competition when welfare maximizing jurisdictions levy source-based corporate taxes and multinational enterprises choose tax-efficient capital-to-debt ratios. Under separate accounting, multinationals shift debt from low-tax to high-tax countries. The Nash equilibrium of...

The EU Commission is advocating a common consolidated tax base for the corporate income tax, accompanied by a revenue sharing mechanism based on formula apportionment. We analyse tax competition in such a regime, focussing on the interaction between the definition of the tax base and the...

This paper investigates the choice of apportionment factors under a corporate tax system of Formula Apportionment. In contrast to perceived wisdom, we show that the apportionment formula contains both mobile (capital) and immobile (labor) factors if jurisdictions are granted full fiscal autonomy...

We study tax evasion and decentralized tax enforcement in a federal economy with mobile capital and the endogenous formation of multiregional companies. Regions use their enforcement policy as a strategic instrument to engage in fiscal competition. Within this framework, we analyze the...

Dramatic declines in capital tax rates among U.S. states and European countries have been linked by many commentators to tax competition and an inevitable race to the bottom. This paper provides an empirical analysis of the reaction of capital tax policy in a given U.S. state to changes in...

German Fiscal Federalism is characterized by a high degree of fiscal equalization which lowers the efficiency of local tax administration. Currently, a reform of the fiscal equalization scheme is on the political agenda. One option is to grant federal states the right to raise surtaxes on...

This paper challenges the view that tax base equalization by the so-called Representative Tax System (RTS) removes inefficient undertaxation in corporate tax competition. The innovation of the paper is that it focuses on a tax on corporate income, instead of the unit tax on capital considered in...

Sub-national governments often finance substantial parts of their budgets via taxes on capital or other mobile factors - despite having access to alternative, less distortionary, revenue sources. This paper develops three hypotheses to explain this pattern and tests them in a natural experiment...

This paper contributes to the discussion on Separate Accounting versus Formula Apportionment in the corporate income taxation of multinational enterprises (MNEs). The innovation of the analysis is that we consider a general equilibrium tax competition model with an endogenously determined world...
