Recent advances in testing for the validity of Purchasing Power Parity (PPP) focus on the time series properties of real exchange rates in panel frameworks. One weakness of such tests, however, is that they fail to inform the researcher as to which cross-section units are stationary. As a...

The empirical literature that tests for purchasing power parity (PPP) by focusing on the stationarity of real exchange rates has so far provided, at best, mixed results. The yen real exchange rate behavior, as compared to other major currencies, has most stubornly challenged the PPP hypothesis...

Using a new methodology that allows for nonlinearities, we find frequent support for sustainability in the debt of a set of Latin American countries. Our findings overturn results obtained with traditional unit-root tests and provide a more realistic alternative to evaluate the external solvency...

The debt crisis in Latin America is associated with the large fiscal imbalances of the 1980s; therefore public finance sustainability occupies the center of stabilization efforts in these economies. The literature examining this question in emerging economies is surprisingly scant and this paper...

Using a new methodology that allows nonlinearities, we find frequent support for external debt sustainability in a number of Latin American countries. Our findings reverse the results for several countries, obtained with traditional unit-root tests and present a richer framework for evaluating...
