Abstract
Este trabajo identifica factores explicativos de la supervivencia de flujos de comercio argentinos utilizando como método de identificación la combinación del método de Análisis de Árbol de Clasificación y Regresión (CART, con sus siglas en inglés) y econometría de corte transversal. Mientras que el primero determina los mejores predictores, el segundo ofrece una función global que vincula a la variable dependiente con aquellos. La combinación de estos métodos permite reducir el número de variables potencialmente explicativas en problemas en los que no existe consenso teórico, o salvar situaciones en las que existen relaciones no lineales, datos faltantes u observaciones anómalas. La aplicación al caso de estudio permite observar que existe una diferencia significativa entre flujos de exportaciones preexistentes y nuevos flujos, a pesar de que las variables explicativas de su duración resulten ser las mismas. || This paper identifies factors that explain the survival of Argentine trade flows using the combination of the Classification And Regression Tree analysis (CART) method and cross-section econometrics as the identification method. While the first determines the best predictors, the second offers a global function that links the dependent variable with those. The combination of these methods allows to reduce the number of potentially explanatory variables in problems in which there is no theoretical consensus, or to resolve situations in which there are non-linear relationships, missing data or anomalous observations. The application to the case study allows us to observe that there is a significant difference between pre-existing export flows and new flows, even though the explanatory variables of their duration turn out to be the same.
