This paper evaluates the fiscal sustainability hypothesis for eight Latin American countries, Argentina, Chile, Colombia, Ecuador, Panama, Peru, Paraguay and Uruguay, during the period 1960 - 2009. Using second generation cointegration panel data models, we test whether Government revenues and primary expenditures are sustainable in the long-run. This methodology allows for cross-sectional dependence among countries and is also appropriated under the existence of potential structural breaks. We found empirical evidence of sustainability of the primary deficit for these Latin American countries but only in a weak sense.
