Several PhD fellowships in economics are offered by the European Doctorate in Economics Erasmus Mundus (EDEEM) Program.
EDEEM is a doctoral programme in economics that gathers 7 leading European institutions coordinated by University of Paris 1, France.
The EDEEM Program welcomes around 25 students each year. Admission is based on excellence in previous Master Degree studies or equivalent. This degree does not have to be in economics, although interest in economics is certainly desirable and a strong background in mathematics will be helpful together with fluent written and spoken English. The programme is organised in three years.
