Alimentos diferenciados: principales métodos de captación, evaluación y valoración de sus atributos de calidad
Palabras clave:
alimentos, atributos, calidad, métodos de valoración, percepciones de los consumidoresResumen
Los mercados de alimentos diferenciados ofrecen productos obtenidos mediante el empleo de tecnologías e insumos, según normas y procesos autorizados y verificados, que garantizan su “calidad”. La creciente demanda de estos productos de alta calidad se debe a los atributos que los mismos poseen para satisfacer las percepciones de los consumidores sobre la salud, la seguridad y otras características relevantes en sus decisiones de compra.
A fin de cuantificar la disposición a pagar por dichos alimentos, el objetivo de este trabajo es analizar los principales métodos de captación, evaluación y valoración de los atributos de calidad percibidos por los consumidores.
Los métodos analizados son los de: Valuación Contingente, Subastas Experimentales, Análisis Conjunto y Precios Hedónicos. En cada uno de ellos, tanto la recolección de los datos así como también su precisión, constituyen elementos estratégicos.
