Abstract

Highlights: Deprivation Cost Functions using Hybrid Latent Variable – Discrete Choice are estimated. Data comes from a stated choice survey applied in zones affected by disasters. Risk perception, safety culture, and confidence on Emergency Response Systems play a major role. Latent variables let us to capture people' heterogeneity for the estimation of DCFs. 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.
