Research at Erasmus School of Economics covers topics in economics and business. The school is organised into four departments: Applied Economics, Business Economics, Econometrics and Economics. Their research is organised into five programmes, headed by research programme leaders. The scope of the research programmes is strongly aligned with the focus of the departments. In fact, the scope of three research programmes - Applied Economics, Econometrics and Economics – is identical to the one of their corresponding department. Only Business Economics, the largest department, has two research programmes: Marketing and Finance & Accounting.
