Abstract * Using panel co-integration techniques and a comprehensive dataset covering the period 1980-2013, this paper finds a positive and significant correlation between national saving and domestic investment rates in Latin America and the Caribbean (LAC). The estimated correlation is approximately 0.39; i.e., for every 1 percentage point of GDP increase in national saving, domestic investment increases by 0.39 percentage points on average. There are however, three nuances to the headline result: i) the estimated correlation has been declining over time; ii) the regional average hides a large degree of intra-regional heterogeneity; and iii) the estimated coefficient is largest amongst the biggest economies in the region. It is concluded that low national saving rates remain a binding constraint for capital accumulation in LAC. JEL classifications: C23, E2, F36
