摘要:A double-log model was estimated on demand for cheese and fluid milk and for the aggregation of imported cheese, fluid milk, and powdered milk in Costa Rica, El Salvador, Guatemala, Honduras, and Nicaragua using time series data 1994-2012. Cheese and fluid milk were price and income inelastic in all countries, except for income in El Salvador. On the other hand, import prices for cheese and fluid milk were often found elastic, but that of powdered milk was inelastic. An increase in incomes augmented imports of fluid milk and cheese, compared to powdered milk. Overall, the substitution effect suggested that increment in imports prices of cheese and fluid milk increased the purchase of powdered milk.
