The COVID-19 pandemic has led to an increase in public debt in most countries. This will increase fiscal pressure in the future. We study how the shape of the optimal nonlinear income tax schedule is affected by this increase. We calibrate the workhorse optimal income tax model to five European...

This paper points to the important role which the elasticity of aggregate capital supply with respect to the net rate of return to capital plays for the efficiency of policymaking in a decentralized economy with mobile capital and spillovers among jurisdictions. In accordance with previous...

We develop a two-region model where the decentralized provision of spillover goods can be financed by means of taxes or user fees. In order to enforce the fees regions have to invest in exclusion. We show that a decentralized solution tends to be inefficient. There will be over-investment in...

We analyse the economic impact of using carbon pricing revenue to fund the EU budget. Such a reform would redistribute from countries with above average carbon intensive production to less carbon intensive countries. Once the reform is implemented, the low carbon countries will prefer a lower...

The loss of international competitiveness of domestic industries remains a key obstacle to the implementation of effective carbon prices in a world without harmonized climate policies. We analyze countries' non-cooperative choices of emissions taxes under imperfect competition and mobile...

This paper contributes to resolving the puzzle that in practice most countries use ad valorem (corporate income) taxation, while a large part of the tax competition literature views business taxes as unit (wealth) taxation. We point to the dual role corporate taxation plays in attracting mobile...

This paper considers the implications of asymmetric information in capital markets for entrepreneurial entry and tax policy. In many countries, governments subsidize the creation of new firms. One possible justification for these subsidies is that capital markets for the financing of new firms...

This paper surveys the literature on the implications of international capital mobility for national tax policies. Our main issue for consideration in this survey is whether taxation of income, specifically capital income will survive, how border crossing investment is taxed relative to domestic...

This paper shows that if an individual's health costs are U-shaped in weight with a minimum at some healthy weight level and if the individual has both self control problems and rational motives for over- or underweight, the optimal paternalistic tax on unhealthy food mitigates the individual's...

This paper develops a theoretical explanation why it may be optimal for higher-level governments to pay categorical block grants or closed-ended matching grants to local governments. We consider a federation with two types of local governments which differ in the cost of providing public goods....
