The relative constancy of nonfinancial corporate tax revenues as a share of U.S. GDP masks offsetting trends in the ratio of corporate profits to GDP (declining) and the average tax rate (increasing). The average tax rate rose steadily between 1996 and 2003, an increase largely attributable to...

In this paper we ask whether recent claims that the US government should switch from the tax credit system to the exemption system are justified. We study corporate taxation in a model where international capital flows are either greenfield investment projects or acquisitions of existing firms,...

This paper investigates the role of economic and political volatility in the process of corporate tax-rate determination. The article is based on a theoretical framework that allows for the ability of multinational firms to choose the optimal timing of foreign investment and to shift profits by...

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...

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 develops a model of a monopolistically competitive industry with extensive and intensive business investment and shows how these margins respond to changes in average and marginal corporate tax rates. Intensive investment refers to the size of a firm's capital stock. Extensive...

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 addresses outsourcing in the two-type optimal income tax model. If the government is able to control outsourcing via a direct tax instrument, outsourcing will not affect the marginal income tax structure. In the absence of a direct tax instrument, and under the plausible assumption...

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...

Thin capitalization rules have become an important element in the corporate tax systems of developed countries. This paper sets up a model where national and multinational firms choose tax-efficient financial structures and countries compete for multinational firms through statutory tax rates...
