Evaluaciones de bienestar ante cambios en la estructura del mercado de papas prefritas congeladas: un análisis con coeficientes aleatorios

  • González, Julia
  • Lacaze, María Victoria

La industria argentina de papas prefritas congeladas (PPC) es altamente diferenciada y concentrada, siendo escasos los estudios que analizan el mercado. El trabajo evalúa el efecto provocado por cambios hipotéticos en la estructura del mercado marplatense de PPC sobre los precios, las ventas y el excedente de los consumidores. Para ello, se estima la demanda directa de los hogares a través de un modelo de elección discreta con coeficientes aleatorios. Se emplea un panel de volúmenes y montos de ventas mensuales, entre 2005 y 2009, provistos por una cadena local de supermercados. Asimismo se utilizan datos de la EPH (INDEC). La fusión Alimentos Modernos-Granja del Sol perjudicaría a los consumidores, evidenciándose una reducción de $13.277 mensuales en su excedente. Si el mercado funcionara bajo una estructura de firmas monoproducto, se observaría un incremento de $67.558 mensuales en el excedente de los consumidores.
