Abstract

Resumen: Este trabajo presenta los resultados más importantes de un modelo de demanda de importaciones de productos maderables y sus implicaciónes para Colombia considerando el período 1980 1999. El modelo teórico usado es el desarrollado por Deaton y Muellbauer en 1980, denominado An Almost Ideal Demand System (AIDS). Este modelo permite estimar funciones de demanda de importaciones y, al mismo tiempo, permite el cálculo de las elasticidades precio e ingreso de los diferentes tipos de producto que participan en un determinado mercado. La metodología de estimación está definida por el modelo denominado Seemingly Unrelated Regresión (SUR). El estudio muestra, de un lado, que Colombia, a pesar de tener un potencial forestal muy considerable aún está lejos de aparecer en las estadísticas internacionales como país exportador de maderas. De otro lado, si Colombia decidiera desarrollar el sector forestal, se enfrentaría a una competencia muy fuerte representada fundamentalmente por Canadá, y algunos países asiáticos. Las elasticidades muestran cómo, en el caso de la madera en tronco, la mayoría de los productos (madera en tronco por países) se comportan como bienes complementarios. Los signos de las elasticidades son los esperados, lo que permite concluir que el modelo se ajusta bastante bien a los datos. / Abstract: This paper presents the main results of a model of import demand of wood products in the U.S. and its implications for Colombia. The time length considered here was 1980-1999. The theoretical model used was developed by Deaton and Muellbauer in 1980 and it is called: An Almost Ideal Demand System. This model allows the estimation of price and income elasticities for different types of wood products. The methodology used consists of the Seemingly Unrelated Regression model (SUR), popular in the econometrics literature. This paper shows, on one hand, that despite of the tremendous forest potential that Colombia has, its participation in international markets is negligible. On the other hand, if Colombia decided to develop the forest sector, it would have to face some strong competitors such as Canada and some Asian countries. The cross-price elasticities show that in the case of round wood the majority of countries behaves like complementary goods. The sign of the elasticities are the expected which allows to conclude that the model well fits the data.
