URPE sponsors our own conferences as well as sessions at annual meetings of economics associations, including the Allied Social Science Associations and the Eastern Economics Association. The next ASSA conference will be in Philadelphia January 3-5, 2014; see our ASSA section for more information. The next EEA conference will be in Boston, March 6-9, 2014; see our EEA section.
Additionally, URPE members organize both annual and occasional conferences, and participate in conferences with an activist, multi-discipline orientation, such as the Left Forum in NYC. A date and place for the next LF conference has not yet been announced; it will probably be in the late spring. Keep checking our site.
One way to find out about other economics and activist conferences is to join the URPE Listserv, or view its archives. We also refer you to other email lists that frequently mention conferences. One excellent source of information on both mainstream and heterodox economics conferences is the Heterodox Economics Newsletter.
