ANALYSIS OF THE INTERDEPENDENCE OF POLITICAL-ECONOMIC UNCERTAINTY BETWEEN LATIN AMERICAN COUNTRIES USING FRACTIONALLY COINTEGRATED MODELS
In this work, the dynamic relationship between the uncertainty series of Brazil, Chile, Colombia and Mexico was analyzed through the econometric framework of integration and fractional cointegration in order to verify the degree of spillover and interdependence of political-economic uncertainty between the countries. In 83% of the estimations of fractional cointegration orders indicated stationarity and long memory in the series and 17% showed non-stationarity and mean reversibility. The results of the fractional cointegration models suggest that there is no spillover of uncertainty between the observed countries. Systemically, there is no transmission and joint interdependence for the four countries analyzed.
