The “What Works” Research Brief No. 2 discusses the most recent evidence on the effectiveness of active labour market measures in increasing employability and job quality of conditional cash transfers (CCT) beneficiaries. It draws from new knowledge on the effectiveness of these type of programmes summarized in the Synthesis Report “What works: Active Labour Market Policies in Latin America and the Caribbean” and the particular experience of a programme implemented in Argentina that provided skills upgrading and job placement support to eligible beneficiaries of the CCT programme Plan Jefes.
