Fiscal sustainability remains a paramount challenge for small economies with high debt and greater vulnerability to climate change. This paper applies the model-based sustainability test for fiscal policy in a panel of 16 Caribbean countries during the period 1980-2018. The results indicate that the coefficient on lagged government debt is positive and statistically significant, implying that fiscal policy in the Caribbean takes corrective actions to counteract an increase in the debt-to-GDP ratio. Nonlinear estimations, however, show that the quadratic debt parameter is negative, which indicates that fiscal policy response is not adequate to ensure sustainability at higher levels of debt. We also find that the fiscal stance tends to be countercyclical on average during the sample period. These empirical results confirm that maintaining prudent fiscal policies and implementing growth-enhancing structural reforms are necessary to build fiscal buffers and ensure debt sustainability with high probability even when negative shocks occur over the long term.

In the last few decades there has been little convergence of income levels in Latin America with those in the United States, in sharp contrast with both emerging Asia and emerging Europe. This paper argues that lack of convergence was not the result of low investment. Latin America is poorer because of lower human capital levels and lower TFP—not because of a lower capital-output ratio. Cross-country differences of TFP in turn are associated with differences in human capital, governance and business climate indicators. We demonstrate that once levels of human capital and governance are taken into account, there is strong conditional cross-country convergence. Poor countries with high levels of human capital, governance or business climate indicators converge rapidly. Poor countries without those attributes do not. We show that low investment is the result of low TFP and thus GDP growth—not the cause.
