Formed in 1992, the International Association for Feminist Economics (IAFFE), is independent of the American Economic Association (AEA) and seeks to challenge the masculine biases in neoclassical economics.[90] While the majority of members are economists, it is open "not only to female and male economists but to academics from other fields, as well as activists who are not academics" and currently has over 600 members in 64 countries.[91] Although its founding members were mostly based in the US, a majority of IAFFE's current members are based outside of the US.
