The document discusses import substitution industrialization (ISI) policies adopted in Latin America between the 1940s-1960s as a strategy for economic growth and development. ISI aimed to promote domestic industries like textiles and appliances to replace imports by using protective trade policies. While ISI initially saw some success, Latin American countries became increasingly dependent on exports of primary commodities, which deteriorated their terms of trade over time. ISI eventually declined as countries struggled with inefficient industries and faced debt crises in the 1980s.
