MODELO DE DEMANDA PARA BOVINOS CARNE EN EL CENTRO OCCIDENTE DE MEXICO 1996-2017 Sandra Figueroa-Reyes Samuel Rebollar-Rebollar Eulogio Rebollar-Rebollar Alfredo Rebollar-Rebollar Juvencio Hernández-Martínez Estudios Agrarios Demanda Occidente carne bovina elasticidades región Centro El objetivo fue evaluar el impacto de los factores que determinan la demanda de carne bovina en canal en la región Centro-Occidente de México durante 1996-2017, con elasticidades. Se utilizó un modelo de regresión múltiple exponencial doble logaritmo. La variable dependiente fue la demanda de carne de bovino y las regresoras el precio real al consumidor de carne bovina, precio real al consumidor de carne de cerdo e ingreso real per cápita. En la región Centro-Occidente de México, la demanda respondió inversa e inelásticamente al precio del producto (-0.37), directa e inelástica al precio de la carne de cerdo (0.16), directa e inelástica al ingreso (0.39). Se concluye que el ingreso del consumidor y el precio de la carne bovina generaron mayor respuesta en el comportamiento regional de la demanda de esa carne. 2019 artículo científico 1405-9282 https://www.redalyc.org/articulo.oa?id=14161295002 https://www.redalyc.org/journal/141/14161295002/ https://www.redalyc.org/journal/141/14161295002/html/ https://www.redalyc.org/journal/141/14161295002/14161295002.epub https://www.redalyc.org/journal/141/14161295002/movil es http://www.redalyc.org/revista.oa?id=141 Revista Mexicana de Agronegocios application/pdf Sociedad Mexicana de Administración Agropecuaria A.C.
