Abstract: Deprivation Costs Functions (DCFs) are key to designing effective relief distribution operations after disasters. In this paper, data are collected in Colombia and Ecuador to estimate DCFs for water and food, considering the influence of individuals' attitudes on preparedness, risk perception, and trust in response agents. Hybrid Choice Models are used to analyze and compare the estimated DCFs. The analyses confirm that DCFs differ by commodity. Additionally, socioeconomic characteristics of individuals influence their willingness to pay for critical supplies to reduce their own suffering. Preparedness, risk perceptions and trust in response agents impact individuals' behavior in disaster situations. The results also show that community and religious groups are considered the most trusted response agents in both countries. As a result, their involvement in official relief efforts should be more articulated. Colombia and Ecuador show significant differences in their estimated DCFs, confirming that deprivation costs are context-specific by nature. As such, DCFs should not be directly transferred among disaster locations. The findings from this study will support decision-makers in designing effective preparedness and response plans that are based on trust relationships that serve as foundations for community resilience.
