We use a laboratory experiment to investigate the behavioral effects of obligations that are not backed by binding deterrent incentives. To implement such 'expressive law' we introduce different levels of very weakly incentivized, symmetric and asymmetric minimum contribution levels (obligations) in a repeated public goods experiment. The results provide evidence for a weak expressive function of law: while the initial impact of high obligations on behavior is strong, it decreases over time. Asymmetric obligations are as effective as symmetric ones. Our results are compatible with the argument that expressive law affects behavior by attaching an emotional cost of disobeying the own obligation.

AbstractThis paper provides a brief review of the academic literature that assesses the quantitative importance of tax avoidance behaviour of multinational entities (MNEs) by means of income shifting from high-tax to low-tax affiliates. Existing studies unanimously report evidence in line with tax-motivated profit shifting (despite using different data sources and estimation strategies). In terms of shifting channels, there is evidence consistent with strategic mispricing of intra-firm trade, the location of valuable intellectual property at low-tax affiliates and debt-shifting activities. The quantitative estimates vary across approaches and studies though. The paper moreover stresses that some care should be warranted when interpreting profit shifting estimates as they often rely on non-trivial assumptions.

AbstractTheory suggests that large firms are more likely to engage in lobbying behaviour and are geographically more mobile compared with smaller entities. Conditional on jurisdiction size, policy choices are thus predicted to depend on the shape of a jurisdiction's firm size distribution, with more business‐oriented policies being enacted if jurisdictions host large firms. The paper empirically tests this prediction using local business taxation in Germany as a testing ground. Exploiting rich and exogenous variation in municipalities' firm size structures, we find evidence for an inverse relationship between the size of hosted entities and municipalities' local business tax choices. The effect is statistically significant and quantitatively relevant, suggesting that the rising importance of large businesses may trigger shifts towards a more business‐friendly design of (tax) policies.

The purpose of this paper is to assess whether the timing of elections affects tax policy choices. To do so, we exploit information on the German local business tax which is set autonomously by German municipalities. As the dates for local council elections vary across German states, the data allows us to disentangle effects related to the timing of elections from common trends. The findings support the notion of a political cycle in tax setting as the growth in local business tax rates is significantly reduced in the election year and the year prior to the election, while it significantly increases in the year after the election. This pattern turns out to be robust against a number of sensitivity checks.

In recent years several countries have augmented their national tax laws by transfer pricing legislations which intend to limit the leeway of multinational firms to exploit international corporate tax rate differences and relocate profit to low-tax affiliates by distorting intra-firm transfer prices. The aim of this paper is to empirically investigate whether these laws are instrumental in restricting shifting behaviour. To do so, we exploit unique information on the scope and evolution of national transfer pricing laws and link it with panel data on European multinationals. In line with previous studies, we find evidence for tax-motivated profit shifting. The analysis further suggests that transfer pricing rules significantly reduce shifting activities. The effect is economically relevant, suggesting that the legislations may be socially desirable despite the high administrative burden they impose on firms and tax authorities.

The purpose of this paper is to assess whether politicians manipulate the timing of tax rate changes in a strategic way to maximize reelection prospects. To do so, we exploit the German local business tax as a testing ground which is set autonomously by German municipalities. As election dates vary across local councils, the data allows us to disentangle effects related to the timing of elections from common trends. Using a rich panel data-set for German municipalities, we assess the impact of elections on local business tax choices. The findings support the notion of a political cycle in tax setting behavior as the growth rate of the local business tax is significantly reduced in the election year and the year prior to the election, while it jumps up in the year after the election. This pattern turns out to be robust against a number of sensitivity checks.

Over the past decade, several countries augmented their national tax law by transfer pricing legislations in order to limit opportunities for tax-motivated transfer price distortions and the associated relocation of multnational income from their borders. The aim of this paper is to empirically investigate the impact of transfer pricing laws on multinational profit shifting behaviour. To do so, we collect unique data on the evolution of national transfer price requirements in Europe over the past decade. This data is linked to accounting information on multinational firms in the EU and to corporate tax rate data. In line with previous studies, we find that multinational firms engage in significant tax-motivated profit shifting behaviour. The analysis furthermore suggests that transfer price documentation rules are instrumental in restricting income shifting activities. The effect is statistically significant and economically relevant. Our analysis thus underpins the benefits of implementing transfer price documentation requirements and suggests that they may be socially desirable despite the high administrative burden they impose on firms and tax authorities.
