The theme of the 2015 congress is Taxation in a Global Economy. Increased international mobility of economic activity via FDI, trade, and migration has resulted in a tax environment that requires decision makers to consider their choices in a global context. In particular, the mobility of tax bases poses serious questions for the implementation of tax policy and the sustainability of public goods. These issues and more, including tax competition between governments, tax planning by firms, and potential cooperative solutions will be topics of discussion.Keynote speeches will be given by:Rosanne Altshuler (Professor of Economics; Rutgers University), Ruud de Mooij (Deputy Division Chief in the Tax Policy Division of IMF’s Fiscal Affairs Department), Mihir Desai (Mizuho Financial Group Professor of Finance, Harvard Business School) and Michael Devereux (Director of the Oxford University Centre for Business Taxation, Professor of Business Taxation). Furthermore, the congress features policy panels on the challenges facing open economies, including high-ranking policy makers and academics. While the theme of the Congress is Taxation in a Global Economy, contributed papers on any topic within the field of public economics will be considered, as is traditional at IIPF congresses.The papers to be presented will be selected by the Scientific Committee.
