Estimación de la tasa social de descuento a largo plazo en el marco de los sistemas nacionales de inversión. Aplicación al caso chileno

Abstract: Este artículo analiza las distintas metodologías usadas en algunos países para estimar la tasa de descuento a largo plazo utilizada en proyectos públicos. Adicionalmente, estima, para Chile, la tasa de descuento, con base en dos metodologías: la primera es una variación del método de descuento gamma, propuesto por Weitzman (2001); la segunda usa la fórmula de Ramsey que se deriva de un modelo de crecimiento para estimar la tasa social de preferencia por el tiempo

“…Therefore, the total return obtained from the presence of direct economic activities linked to the lake was US$ 28,935.62 per year. The environmental rate or social discount rate (equal to 6%) estimated for Chile by the Ministry of Social Development was used to calculate the current value of economic rent (Edwards, 2016). Likewise, a growth rate "g" of future flows of 2% was assessed, taking as a reference an average growth of the national product (GDP) of the last years, obtaining perpetuity with the increase.…”

“…For this type of methodology, a social discount rate generated by the country must be always considered (Edwards, 2016), which have an impact in the final result. A high social discount rate means that society finds it more important to favor the value of use in the present, than to prioritize the use value of our resources in the future.…”

“…This study conducts a review of SDR estimation by distinguishing four evaluation periods, from the short to the long term: the immediate future (1-5 years), the medium future (6-20 years), the distant future (21-50 years) and the far distant future (51-100 years). Our estimates for a developing country, Ecuador, employ the gamma discounting mechanism, proposed by Weitzman (2001), to integrate the views of a diverse group of decision-makers, adapting a questionnaire so that it can be used to adjust the interval estimation and so refine the results (Edwards, 2016). Additionally, we present an adjustment in which we consider the present value bias generated by time preferences in a short-term context.…”

“…Los proyectos de inversión son evaluados a raíz de la proyección de flujo de fondos y su tasa de descuento, es importante destacar que las ventas y gastos definen la ecuación financiera de las empresas (Dapena & Alonso, 2015). Uno de los parámetros de mayor importancia en la evaluación de proyectos es, la tasa de descuento, ya que a través del tiempo compara los flujos de beneficios (Edwards, 2016). Esta tasa de descuento permite traer a valor presente los flujo futuros sean positivos o negativos, que se han obtenido a través de la estructuración del presupuesto de capital.…”
