Over the last 20 years Cambodia has cut poverty rates by a third on the back of rapid economic development; yet most of its people are still vulnerable to malnutrition, natural disasters and precarious employment. So in 2011 the Cambodian Government launched a ‘National Social Protection Strategy for the Poor and Vulnerable’ (NSPS). Our study feeds into this by probing rates of return to investments in social protection, as part of a novel approach based on a dynamic microsimulation. In partnership with UNICEF, we call for a range of instruments including cash transfers for children, social pensions, and public works programmes. Today we're joined by the co-author of the report, Dr. Franziska Gassmann.
