Investment Rating - The report does not explicitly provide an investment rating for the industry Core Insights - The value of a statistical life (VSL) is crucial for cost-benefit analysis (CBA) in road safety and socio-economic cost calculations of road crashes, particularly in low- and middle-income countries (LMIC) where specific VSL estimates are often lacking [2][9] - A new value transfer approach is proposed to estimate VSL in countries without specific data, utilizing income elasticities to adapt VSL estimates from other countries [5][12] - The study emphasizes the need for more VSL research in LMICs, highlighting the limited number of existing studies [5][31] Summary by Sections Methodology - A unit value transfer approach is utilized, determining a base VSL from 32 countries to estimate VSL in other nations based on income per capita [3][4] - The resulting VSL transfer functions are defined for LMIC and high-income countries (HIC), with specific equations relating VSL to Gross National Income (GNI) per capita [4][31] Results - The VSL for LMIC ranges from approximately 22,000 USD to 1.1 million USD, while for HIC it ranges from 1.2 million USD to 4.8 million USD [4][25] - The mean VSL is reported as 2.6 million USD, with significant variation observed between LMIC and HIC [23][28] Recommendations - The report recommends applying the new VSL transfer approach for CBA in countries lacking appropriate country-specific VSL, and suggests developing transfer functions for non-fatal injuries [5][33] - Future research should focus on increasing the number of VSL studies in LMIC, particularly in low-income countries [31][35]
