Abstract: Introducción:Esta investigación estimó la elasticidad de la demanda intramolecular, marca y genérico, para tres patologías trazadoras, Hipertensión Esencial, Diabetes e Hiperlipidemia, en el mercado ético y privado colombiano, a partir de una especificación dinámica del modelo AIDS basado en técnicas de cointegración. La estimación de la elasticidad de la demanda intramolecular permite concluir que tanto medicamentos de marca como genéricos son inelásticos ante cambios en su precio, son bienes de lujo según elasticidad gasto y parece existir sustitución intramolecular por el signo obtenido de la elasticidad de sustitución.Abstract:This investigation estimated the elasticity of the intramolecular demand between generics and brand name in pharmaceutical private market in Colombia for three pathologies: Essential Hypertension, Diabetes and hyperlipidemia, from dynamic specification of the AIDS model based on cointegration techniques. The intramolecular price elasticity estimated shows that both generic and brand name drug are inelastic and does not respond to price changes, they are luxury goods from expenditure elasticity results and seems to exist intramolecular substitutability because of the coefficient sign in cross-price elasticity.
