Because the banana trade is a large world-wide business, a number of studies have been carried out on various aspects of the fair trade banana market, including
political ecology, tariffs and quotas, price competition, organic growing, and retail price wars. Fair trade certification programs have been criticized on several grounds. Griffiths has challenged the ethics of fair trade labels in the
fair trade debate, and, in the
Journal of Business Ethics, has pointed out instances in which negative research is not published and academics choose only successful coops or fair trade organizations for study. In the Dominican Republic, Shreck found minimum pricing, and exclusivity of certification worsened socioeconomic disparity within farming communities, and limited access for non-certified farmers to the market. Furthermore, Shrek found that the standards of certification programs prioritized market interests over farmer rights and well-being. Frank has argued that fair trade initiatives do not generally foster an empowering partnership between consumers and farmers. ==Foncho campaign==
