If you completed 14.009x Good Economics for Hard Times before the launch of the Public Policy Track in fall 2023, you can apply the course to the International Development Track indefinitely. However, if you completed 14.009x before fall 2023 and wish to apply it to the Public Policy Track, it cannot be counted towards the International Development Track. In this case, you will need to complete two other International Development Track electives (excluding 14.009x) and the three core courses to earn the International Development credential. Starting from fall 2023, completing 14.009x will only be credited towards the Public Policy Track.
