What are the macroeconomic effects of tax adjustments in response to large public debt shocks in highly integrated economies? The answer from standard closed-economy models is deceptive, because they underestimate the elasticity of capital tax revenues and ignore crosscountry spillovers of tax...

This survey summarizes the state and development of European tax policy, in particular discussing the harmonization progress in direct as well as indirect taxes. Based on an overview over the theoretical and empirical literature on tax competition, we further ask whether increased tax...

Europe's debt crisis casts doubt on the effectiveness of fiscal austerity in highly-integrated economies. Closed-economy models overestimate its effectiveness, because they underestimate tax-base elasticities and ignore cross-country tax externalities. In contrast, we study tax responses to debt...

This paper develops a model of tax competition with three countries, which initially form a union where countries refrain from using different tax rates in different sectors of the economy. We study the impact of one country leaving the union. We show that the introduction of discriminatory...

In the context of a stylised game theoretical framework of capital tax competition, we show that when repeated policy interactions are associated to a systematic punishment of the deviating policymaker, a co-ordinated outcome can be the solution to the non co-operative tax game. This result...
