This paper explores the nature, significance and policy implications of spillovers in international corporate taxation-the effects of one country's rules and practices on others. It complements current initiatives focused on tax avoidance by multinationals, notably the G20-OECD project on Base...

Under the assumption of no arbitrage exchange rate target zone credibility is tested by whether domestic interest rates fall within “rate-of-return bands” between the maximum and minimum home-currency rate of return on a foreign investment absent a devaluation. Under the assumption of...

This paper develops a political-economy model of the budget process focusing on the common pool problem of the public budget. We show that the externality arising from the fact that public spending tends to be targeted at individual groups in society while the tax burden is widely dispersed...

This paper examines the impact of trade costs on real exchange rate volatility. We incorporate a multi-country Ricardian model of trade, based on the work of Eaton and Kortum (2002), into a macroeconomic model to show how bilateral real exchange rate volatility depends on relative technological...
