This paper contributes to resolving the puzzle that in practice most countries use ad valorem (corporate income) taxation, while a large part of the tax competition literature views business taxes as unit (wealth) taxation. We point to the dual role that corporate taxation plays in attracting...

Petroleum administration can be regarded as a principal-agent problem. The government allocates exploration and production rights to petroleum companies on behalf of the population. The government is the principal and the companies are agents. With the aim of capturing revenue for the state, the...

Tax uncertainty often negatively affects investment. Advance tax rulings (ATRs) are commonly used as a measure to provide tax certainty. Rulings are currently controversially discussed in the context of tax planning activities of multinational firms (Luxembourg Leaks). We analyze ATRs as tax...

We study the economic effects of unilateral adoption of corporate tax policies that include destination-based taxes and/or cash ow taxes in a heterogeneous agent model in which multinational firms can endogenously shift income between countries using transfer prices. Standard pass through...

It is well-known that cash-flow business taxes with full loss-offset, and their present-value equivalents, are neutral with respect to firms' investment decisions when firms are riskneutral and there are no distortions. We study the effects of cash-flow business taxation when there is bankruptcy...

The digital economy is characterized by the use of intellectual property such as software, patents and trademarks. The pricing of such intangibles is widely used to shift profits to low-tax countries. We analyze the role of a source tax on royalty payments for abusive transfer pricing, and...

We investigate the neutrality features of an ACE tax reform proposal suggested for the company tax reform in Germany. As a pure ACE tax system is not directly feasible in practice, certain elements have been changed: the traditional income tax of non-corporations remains progressive; there is a...

The standard tax theory result that investment should not be distorted is based on the assumption that profits are locally bound. In this paper we analyze the optimal tax policy when firms are internationally mobile. We show that the optimal policy response to increasing firm mobility may be...

The purpose of this study is to analyze the rates of R&D investments and taxes levied on profits of firms that can optimize the labor productivity of nations. Statistical evidence, based on OECD data, reveals that high rates of R&D intensity and tax on corporate profits do not maximize the labor...

This paper explores the efficiency distortions under two types of destination-based corporate cash-flow taxes. Auerbach and Devereux (2015) have shown that a sales-apportioned cash-flow tax will distort consumer prices; this paper shows that those distortions are generally quite small, and are...
