Abstract: [ES] El objetivo es evaluar si los precios del frijol presentan volatilidad y si tiene implicaciones en la seguridad alimentaria de la población. Se aplicaron modelos simétricos y asimétricos de la familia ARCH a tres variedades de frijol en ocho mercados mexicanos. Los resultados mostraron una alta per-sistencia de volatilidad en frijol pinto y negro, la cual es mayor en los mercados locales que en los que tienen diferente punto de origen y destino. Por lo que dicha volatilidad impacta sobre las decisiones de consumo de la población más pobre. [EN] The objective is to evaluate whether bean prices present volatility clustering effects and whether these have implications for the food security of the population. Symmetric and asymmetric mod-els belonging to the ARCH family were used. They were applied to three bean varieties for eight Mexican markets. The results showed a high persistence of volatility in pinto and black beans, the persistence is bigger in local markets than in those with different point of origin and destination. The volatility of the three varieties impacts on the consumption decisions of the most disadvantaged population.
