Utilizando la metodología de valoración contingente (VC), se estima la disposición a pagar (DAP) de la población de Santiago por un programa que reduzca 50% la contaminación atmosférica que la afecta. Las estimaciones realizadas permiten inferir que la DAP promedio individual es de entre 10 y 17 dólares por año. Con ello, los beneficios totales del programa fluctúan entre 280 y 470 millones de dólares. Conjuntamente, se determina la influencia que sobre la DAP tienen las características personales de los individuos (edad, sexo, educación), la percepción de los mismos sobre la gravedad de la contaminación (seriedad, prioridad), y su apreciación o posición respecto de otras variables de interés (efectividad del gobierno, interés en el medio ambiente, preocupación por las generaciones futuras, etc.). Se discuten los resultados a la luz de las particularidades metodológicas de la VC y de las características de la población analizada.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract This article estimates the benefits of an environmental improvement programme implemented in Santiago de Chile. Using the methodology of contingent value (CV), an estimation was made of the Santiago population's readiness to pay (RTP) for a programme that would reduce the local atmospheric pollution by 50 percent. The estimations made allowed the inference to be drawn that average individual RTP was between USD IO and 17 per year. This would mean that the total benefits of the programme would fluctuate between USD 280 million and 470 million. At the same time, a determination was made of the influence on an individual's RTP of personal characteristics (age, gender and education). Also determined was the individual's perception of the gravity of the pollution problem (seriousness, priority); and the individual's appreciation of, or position in regard to, other variables of interest (the government's effectiveness, interest in the environment, concern for future generations, etc.). The results are discussed in the light of methodological peculiarities in the cv, and of the characteristics of the population studied.]]></p></abstract>
