Book excerpt: Nearly half of trade agreements concluded in the past five years included either a labor chapter or labor provision that makes reference to international labor standards and ILO instruments. The evidence so far suggests that labor provisions have been an important tool for raising awareness and improving laws and legislations with respect to workers' rights, increasing stakeholder involvement in negotiation and implementation phases, and developing domestic institutions to better monitor and enforce labor standards. But challenges remain, particularly with respect to sustainability of impacts, coherence, and cooperative efforts. This new report, part of the Studies on Growth with Equity series, gives a full examination of the scope and effectiveness of these labor provisions.
