Abstract:
Resumen:El presente trabajo utiliza una Aproximación Lineal del Modelo Casi Ideal de Demanda (Linear Approximation/Almost Ideal Demand System) para examinar los gastos de los colombianos en la canasta básica, y estimar sus respectivas elasticidades precio y gasto, a partir de datos de series de tiempo para Colombia en el período de 1968-2007. Las elasticidades gasto y precio, compensadas y no compensadas, presentan los signos esperados, siendo en su mayoría menores en valor absoluto a uno y estadísticamente significativas.Abstract:This work uses a Linear Approximation of the Almost Ideal Demand System (LA/AIDS) to examine Colombian's expenditure in daily needs and to estimate the respective expenditure and price elasticities using Colombian time series from 1968 to 2007. The results show that the expenditure and price elasticities (compensated and not compensated) have the expected signs, most of them being less than one in absolute value and statistically significant.
