Caribbean demand of U. S. and rest-of-the-World-Starchy Food : a restricted source differentiated almost ideal demand system

Las elasticidades de demanda por importaciones per cápita de féculas desde Estados Unidos y el resto del mundo hacia los países del Caribe son estimadas mediante el modelo de demanda casi ideal con restricción y diferenciación por orígenes (RSDAIDS). Para el trigo y el arroz las elasticidades-precio propias son negativas y también las elasticidades-precio cruzadas. Esto sugiere que una reducción en el precio de las exportaciones del trigo y el arroz por parte de los países oferentes puede tener un efecto positivo sobre la seguridad alimentaria de los países del Caribe. Además, parece existir una separación de los mercados de trigo y arroz en los países del Caribe dependiendo del origen de los productos (Estados Unidos o el resto del mundo). De esta manera se protege a los oferentes de estos productos de la competencia.
