We study whether the corporate tax system provides incentives for risky firm investment. We first model the effects of corporate tax rates and tax loss offset rules on firm risk-taking. Testing the theoretical predictions, we find that firm risk-taking is positively related to the length of tax loss periods. This result occurs because the loss rules shift a portion of investment risk to the government, inducing firms to increase their overall level of risk-taking. Moreover, the corporate tax rate has a positive effect on risk-taking for firms that can expect to use their tax losses, and a negative effect for those that cannot. Thus, the effect of taxes on risky investment decisions varies among firms, and its sign hinges on firm-specific expectations of future tax loss recovery.

This article analyzes profit taxation according to the arm's length principle in a new model where heterogeneous firms sort into foreign outsourcing. We show that multinational firms are able to shift profits abroad even if they fully comply with the tax code. This is because, in equilibrium, intra-firm transactions occur in firms that are better than the market at input production. Transfer prices set at market values following the arm's length principle thus systematically exceed multinationals' marginal costs. This allows for a reduction of tax payments with each unit sold. The optimal organization of firms hence provides a new rationale for the empirically observed lower tax burden of multinational corporations.

Little is known about how banks shift profits to low-tax countries. Because of their specific business model, banks use profit shifting channels different from those of other firms. We propose a novel and bank-specific method of profit shifting: the strategic relocation of proprietary trading to low-tax jurisdictions. Using regulatory data from the German central bank, we show that a one percentage point lower corporate tax rate increases banks' fixedincome trading assets by 4.0% and trading derivatives by 9.0%. This increase does not arise from a relocation of real activities (i.e. traders); instead, it stems from the relocation of book profits. Terms of use: Documents inJEL-Codes: H250, G210, F210.

Heterogeneous firm productivity seems to provide an argument for governments to pursue 'pick-the-winner' strategies by subsidizing highly productive firms more, or taxing them less, than their less productive counterparts. We appraise this argument by studying the optimal choice of effective tax rates in an oligopolistic industry with heterogeneous firms. We show that the optimal structure of tax differentiation depends critically on the feasible level of corporate profit taxes, which in turn depends on the degree of international tax competition. When tax competition is moderate and profit taxes are high, favoring high-productivity firms is indeed the optimal policy. When tax competition is aggressive and profit taxes are low, however, the optimal tax policy is reversed and low-productivity firms are tax-favored.

In 2009, the United Kingdom abolished the taxation of profits earned abroad and introduced a territorial tax system. Under the territorial system, firms have strong incentives to shift profits abroad. Using a difference-in-differences research design, we show that profits of UK subsidiaries in low-tax countries increased after the reform compared to subsidiaries of non-UK multinationals in the same countries, by an average of 2.1 percentage points. The increase in profit shifting also leads to increases in measured productivity of the foreign affiliates of UK multinationals of between 5 and 9 percent.

This paper investigates how multinational banks use internal debt to shift profits to low-taxed affiliates. Using regulatory data on multinational banks headquartered in Germany, we show that banks use this tax avoidance channel more aggressively than non-financial multinationals do. We find that a ten percentage points higher corporate tax rate increases the internal net debt ratio by 5.7 percentage points, corresponding to a 20% increase at the mean. Our study also takes into account the existence of conduit entities, which simply pass through financial flows. If conduit entities are systematically located in low-tax countries, previous studies may have underestimated the extent of debt shifting .
