Competitividad de la administración de las aduanas en el marco del comercio internacional

Customs clearance is a required act for international traders. However, customs clearance can be a daunting process to enter new markets. Therefore, it is of fundamental importance that customs administrations act as facilitators of commercial process and a security provider to ensure timely delivery and cost reduction of international trade, which leads to optimization of international logistics and competitive advantage of firms and nations in the global value chain (Shujie & Zhao, 2009). This study evaluates, through Principal Component Analysis, customs competitiveness at the international trade framework considering the most important variables that affect customs competitiveness and economic performance with respect to these variables. The objects of study are twenty-nine countries. The results shown in the customs competitiveness index point out that the most competitive countries in customs according to the variables assessed are -in a descending order- Panama, followed by China, India, Germany, Korea, Sweden, Singapore, Turkey, Thailand and Chile.

Relación de causalidad entre el índice de precios del productor y el índice de precios del consumidor incorporando cambios estructurales: El caso de México

En este articulo se analiza la relacion de causalidad entre losprecios del productor y del consumidor para el caso de Mexicodurante el periodo de enero de 1994 a febrero de 2012. Paraello, se utilizan las pruebas de raiz unitaria (Dickey-Fuller 1979y 1981; Phillips-Perron, 1988; Lee-Strazicich, 2003) y pruebasde causalidad (Granger,1969; Toda y Yamamoto,1995). Los resultadosindican que, tomando en cuenta cambios estructuralesy la tendencia deterministica, ambos indices de precios son estacionarios.La relacion de causalidad es unidireccional, de losprecios del consumidor a los precios del productor.
