The Relationship between National Saving and Investment in Latin America and the Caribbean

Abstract

Using panel cointegration techniques and a comprehensive data set 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. The estimated correlation is approximately 0.39; that is, for every one 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 intraregional heterogeneity; and (iii) the estimated coefficient is largest among the biggest economies in the region. Low national saving rates remain a binding constraint for capital accumulation in Latin America and the Caribbean.
