Economics (MA)

Joint degree in International and Development Economics with the Yale Graduate School of Arts and Sciences

On This Page

    Program Overview

    In 1984, the faculties of the Economics Department and of the School of the Environment recognized the value of integrating instruction in economic development and in natural resources and formalized a degree program that, in two and one-half years, leads to both the Master of Arts degree in Economics and one of four degrees from the School of the Environment. The program is designed for individuals who envision careers whose central missions relate natural resource or environmental issues to economic development or trade.


    Students in the 2.5-year joint program earn a Master of Arts degree (MA) in International and Development Economics (IDE) from Yale’s Graduate School of Arts and Sciences (GSAS) and one of four degrees from the School of the Environment (YSE), Master of Environmental Management (MEM), Master of Environmental Science (MESc), Master of Forest Science (MFS), or Master of Forestry (MF).
    Pursuing a joint program reduces the total time of study by one year.

    Course of Study

    Each environment degree program requires a completion of 36 credits as well as a summer internship and a thesis or a capstone project. In addition, all joint-degree students are required to attend two weeks of technical skills training (“MODs”) before beginning their studies at YSE. These are hands-on workshops, offered every August, that teach plant identification, ecosystems management, land measurement, and urban ecosystem analysis. Please see Degree Programs at YSE for more information.
    For the Master of Arts degree, the IDE program of study revolves around a core curriculum of six required courses, and at least two elective courses of each student’s choosing. The core courses are designed to provide students with rigorous academic training, as well as with tools that can be used in policy analysis. These semester-long courses are required of all students. See IDE Core Curriculum for more information.

    Students may begin their studies at the School of the Environment (YSE) or at the Graduate School of Arts and Sciences (GSAS).
