In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

To analyze the optimal social insurance package, we set up a two-period life-cycle model with risky human capital investment in which the government has access to labor taxation, education subsidies and capital taxation. Social insurance is provided by redistributive labor taxation. Moreover,...

There is a growing concern that governments lose substantial corporate tax revenue because of profit shifting through transfer-pricing and thin-capitalization strategies. Existing literature studies profit shifting and transfer pricing separately. In practice, the choice of debt-to-asset ratios...

We demonstrate that the choice of the transfer price and its effect on intra-firm trade and investment depends on the probability of detection and thus on the measure, on which tax authorities base their audit. A policy implication of the paper is that it should be preferable to condition audits...

This paper examines the flexibility of multinational firms to use income-shifting strategies within a tax year to react to operating losses. First, we develop an analytical model that considers how affiliate losses can be adjusted by using the transfer prices of tangible and intangible assets,...

This study develops theory and discusses implications of inflexibility in tax-motivated income shifting. We show that inflexibility to adjust income-shifting strategies within a tax year in response to losses implies that income-shifting incentives are based on the expected rather than the...
