The Latin American Economic Outlook (LEO) analyses critical aspects related to sustainable and inclusive development in Latin America and the Caribbean (LAC). Since the first LEO launch in November 2007, the annual report has compared LAC’s performance with that of other regions, analysed main development challenges and put forward policy recommendations, experiences and good practices. The LEO benefits from the expertise and inputs of co‑authors. Since 2011, the LEO has been published in partnership with the United Nations Economic Commission for Latin America and the Caribbean. In 2013, the Development Bank of Latin America and the Caribbean joined the team of authors and in 2018, the European Commission joined as a main partner of the LEO. This 16th LEO, Investing in Sustainable Development, underscores the urgent need for more and better investment strategies to promote a more sustainable and inclusive future in the region. The report provides policy recommendations to mobilise and attract investments that help advance a better production model, create quality jobs and improve citizens’ well‑being. LEO 2023 analyses investment and socioeconomic trends, presents concrete innovative financing mechanisms and highlights the key role of governance and institutions in promoting further investment while responding to Latin Americans’ demands. Finally, the report underscores the necessity for strengthened international partnerships to propel better investment and enhance regional integration.
