We nd that, on average, households substitute health and food expenditure in response to adverse health shocks. Our estimates unveil substantial heterogeneity in this trade-o mediated by access to social protection, job contract type, and urban or rural location. Households from rural areas -where household heads are more likely to hold informal jobs and lack access to safety nets- engage in more substitution of food expenditure for health expenditure than others. Our ndings suggest that access to formal employment and a higher quality of local institutions can help mitigate the negative consequences of health shocks for households.54 páginasPDFengOpen AccessWorking paperD12 - Consumer Economics: Empirical AnalysisI15 - Health and Economic DevelopmentJ46 - Informal Labor Marketshealth shockshousehold expenditureinformal laborurban-ruralAcceso abiertoAtribucion-NoComercial-CompartirIgual CC BY-NC-SA 4.0Informalidad
