Measuring Willingness-to-Pay in Discrete Choice Models with Semi-Parametric Techniques
Abstract
Es usual estimar la disposición a pagar por mejoras en modelos de elección discreta a través de modelos logit -o extensiones del mismo. Sin embargo, este tipo de modelos posee supuestos distribucionales muy restrictivos. El presente trabajo explora este tipo de problemas y propone una estimación alternativa utilizando técnicas no paramétricas (mediante Simple Index Models). Adicionalmente, se realiza una aplicación empírica a la disposición a pagar por mejoras en los tiempos de viaje en subterráneo en la ciudad de Buenos Aires.
It is usual to estimate willingness-to-pay in discrete choice models through Logit models -or their expanded versions. Nevertheless, these models have very restrictive distributional assumptions. This paper is intended to examine the above-mentioned issue and to propose an alternative estimation using non-parametric techniques (through Simple Index Models). Furthermore, this paper introduces an empirical application of willingness-to-pay for improved subway travel times in the City of Buenos Aires.
