Influence of attitudes and perceptions on deprivation cost functions

Abstract

Appropriate objective function for post-disaster humanitarian logistics models must be a matter based on minimizing social costs. Such social costs require the estimation of proper Deprivation Cost Functions (DCFs). This paper estimates more explanatory DCFs by analyzing the role of psychosocial factors using hybrid Latent Variable – Discrete Choice Models with data from a stated choice survey applied in Colombia. The results demonstrate that risk perception, safety culture, and confidence in Emergency Response Systems play a major role in an individual’s disaster preparedness and in capturing individuals' heterogeneity for the estimation of DCFs.
