Marcos Vera-Hernández, a Professor of Economics in University College London, visited the NCID to give as seminar entitled "Cost-Sharing in Medical Care Can Increase Adult Mortality: Evidence from Colombia".

This paper reassesses the link between ambulatory cost-sharing and health by studying Colombia's entire formal sector labour force observed monthly between 2011 and 2018 with individual-level health care utilisation records linked to payroll data and vital statistics. 

This is the first study to show a relationship between cost-sharing and adult mortality risk in a low- or middle-income country, a relationship that is important to incorporate into social welfare analyses of cost-sharing policies.
