Esta investigación presenta un estudio comparativo de los rendimientos cambiarios latinoamericanos, en el que se usó la metodología de cointegración de Johansen y los modelos asimétricos TGARCH y EGARCH. Los resultados indican que las volatilidades de los rendimientos de Argentina, Brasil, Chile y Colombia no presentan efectos asimétricos. En México y Perú las malas noticias reducen la volatilidad de los rendimientos cambiarios; además, los resultados sugieren que los rendimientos de Argentina, Brasil, Chile y Perú se describen mediante el modelo AR(1)-TGARCH(1,1); mientras que los rendimientos de Colombia y México lo hacen a través del AR(1)-EGARCH(1,1). Finalmente, se usaron rendimientos diarios para el periodo comprendido entre el 2 de enero de 2002 y el 27 de septiembre de 2011.
