In a multi-country general equilibrium economy with mobile capital and rigid-wage unemployment, countries may differ in capital endowments, production technologies and rigid wages. Governments tax capital at the source to maximize national welfare. They account for tax base responses to their...

This paper analyzes optimal linear taxes on labor income and savings in a standard two-period life-cycle model with endogenous leisure demands in both periods and non-insurable income risks. Households are subject to skill shocks in both periods of the life-cycle. We allow for completely general...

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...

By introducing controlled-foreign-company (CFC) rules, the parent country of a multinational firm reserves the right to tax the income of the firm's foreign affiliates if the tax rate in the affiliate's host country is below a specified threshold. We identify the conditions under which binding...

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...

Many countries have introduced patent box regimes in recent years, offering a reduced tax rate to businesses for their IP-related income. Patent boxes are supposed to increase innovative activity, but they are also suspected to aim at attracting inward profit shifting from multinational...

Oates and Schwab (1988) consider an economy with mobil capital and jurisdictions that suffer from local pollution. They show that welfare-maximizing jurisdictions implement the first-best, if they take prices as given and have at their disposal a capital tax and an environmental standard....

The increasing use of intellectual property as a means to shift profits to low-tax jurisdictions or jurisdictions with so-called "patent boxes" is a major challenge for the corporate tax base of medium- and high-tax countries. Extending a standard tax competition model for capital-enhancing...
