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,...

We develop a model of education where individuals face educational risk. Successfully entering the skilled labor sector depends on individual effort in education and public resources, but educational risk still causes (income) inequality. We show that an optimal public policy consists of...

This paper analyzes a model of corporate tax competition with repeated interaction and with strategic use of profit shifting within multinationals. We show that international tax coordination is more likely to prevail if the degree of asymmetry in terms of productivity differences between...

We analyze whether a redistributive government should provide ex ante insurance against unfortunate outcomes or whether it should instead rely on transfers for redistributing income ex post. To this end, we develop a model of education in which individuals face educational risk and wage...

Should a redistributive government optimally subsidize education to provoke a reduction in the skill premium through general equilibrium effects on wages? To answer this question, this paper studies optimal linear and non-linear redistributive income taxes and education subsidies in two-type...

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 reconsiders the welfare effects of "tariff jumping" direct investment if mobile capital is subjected to taxation. In contrast to the conventional wisdom, the receiving country may in this case gain from the incremental inflow of capital, as this diverts tax revenues from the rest of...

This paper studies optimal dynamic tax policy under the threat of political reform. A policy will be reformed ex post if a large enough political coalition supports reform; thus, sustainable policies are those that will continue to attract enough political support in the future. We find that...

Several frictions restrict the government’s ability to tax assets. First, it is very costly to monitor trades on international asset markets. Second, agents can resort to nonobservable low-return assets such as cash, gold or foreign currencies if taxes on observable assets become too high....
