Abstract

El objetivo del trabajo es comparar las estimaciones de un sistema de demanda de alimentos QUAIDS obtenidas empleando dos conjuntos de precios alternativos e información de corte transversal. Se estiman los valores unitarios o precios implícitos ajustados por calidad y los pseudo precios implícitos. La metodología para el cálculo de estos últimos emplea información de gastos de los hogares, sin datos de cantidades. Los resultados muestran diferencias en las magnitudes y signos de los parámetros estimados por el sistema bajo ambas propuestas. Las elasticidades precio, propias y cruzadas, obtenidas con los precios ajustados por calidad arrojan valores más parecidos a los esperables en el caso de alimentos. La diferencia en términos de elasticidades gasto es bastante menor.
