The fifteenth CEPR European Summer Symposium in International Macroeconomics (ESSIM) will take place on 14-19 May 2007. The meeting will be hosted by the Central Bank of the Republic of Turkey, in Izmir. ESSIM is an annual meeting that brings together about 60 economists from across Europe and key researchers from outside the region. It provides a unique opportunity for macroeconomists from different universities and countries to discuss research in a relaxed atmosphere and to develop long-term collaborative relationships. Another important aim of ESSIM is to provide young researchers with the opportunity to meet and discuss their work with senior economists.
