The importance of the Logistics Performance Index in international trade
Logistics and transport increasingly play a pivotal role in international trade relations. The Logistics Performance Index (LPI) analyses differences between countries in terms of customs procedures, logistics costs and the quality of the infrastructure for overland and maritime transport. The aim of this article is to analyse the impact that each of these components has on trade in emerging economies using a gravity model. Furthermore, the study also attempts to detect possible advances in logistics in developing countries, which are grouped into five regions (Africa, South America, Far East, Middle East and Eastern Europe) by comparing the first LPI data published in 2007 with the most re…
Industrial productivity and convergence in Chinese regions: The effects of entering the world trade organisation
Abstract Chinese economic growth is tremendously important, both due to how fast it is occurring and also its effect on the world economy as a whole. The size of the economy and the rate at which it is growing has opened up significant internal regional differences that are visible in the trends displayed by industry as the main exponent of this growth. This article analyses regional differences in industrial productivity using a dynamic approach (Malmquist index), that is, by determining regional productivity growth as well as the change in value added inequality from one region to another (sigma and beta convergence). Both approaches distinguish between the periods dating from 1995 to 200…
An Application of Hybrid Models in Credit Scoring
The predictive capability of parametric and non-parametric models in solving problems related to financial classification has been widely proved in empirical research carried out in the financial field, particulary in problems like bond rating, bankruptcy prediction and credit scoring. However, recently, it has been shown that a combination of different models generally reduces the prediction error, so that the best alternative to consider may not be a specific model but a combination of them. In this paper, we study hybrid systems based on the aggregation of individual (parametric and nonparametric) models. Our hybrids are built by using both parametric and non parametric models as the sys…
Modelos Paramétricos y no Paramétricos en Problemas deCredit Scoring
RESUMENDada la importancia creciente que esta cobrandose la actividad crediticia en la gestion diaria de los bancos, comienza a ser imprescindible la utilizacion de modelos de clasificacion automaticos que faciliten la concesion o no del credito solicitado con alto grado de exactitud, de manera que permita reducir la morosidad.En el trabajo que presentamos se realiza un exhaustivo estudio de la capacidad predictiva de dos modelos parametricos (Analisis Discriminante y Logit) y cinco no parametricos (Arboles de regresion, Redes Neuronales Artificiales, Algoritmo C4.5, Splines de Regresion Adaptativa Multivariante y Regresion Localmente Ponderada) en un problema de concesion de tarjetas de cr…
Relevance of trade facilitation in emerging countries exports
The objective of this article is to analyse trade flows in emerging nations with a maritime boundary, where trade facilitation plays a decisive role in their international development. In order to detect possible patterns in performance, we apply the economic approach of gravity models using the World Bank Logistic Performance Index (LPI) as a good proxy of trade facilitation. The results of the estimation lead to the conclusion that the more complex the transportation of goods is, the more influential the logistics indicator, trade facilitation being most prominent in Middle East exporters.
