The IMF Internship Programme provides an opportunity for highly promising graduate students pursing an advanced degree/PhD. in macroeconomics or a related field to gain a better understanding of the IMF's work and contribute to the institution's mission. Internships are offered to about 50 graduate students each year. Thirty-five (35) to 40 internships are undertaken during the summer between May and September, and another 10 to 15 are done during the winter from November to March. During the 10 to 13 week period, interns work under the supervision of an experienced economist to carry out a research project and prepare a paper. Their paper may be presented to staff in the department at the end of their assignment, and papers of high standard may be published internally. Projects assigned to interns differ from year-to-year depending on the department's work programme.
