The study approaches child protection involvement from an economic perspective, and is thus a niche study in the Hungarian literature. It seeks to quantify the social benefits to society of mitigating the negative impact of involvement in the provision of child protection, and the maximum return on investment in the child protection system for a given payback period and discount rate. As in international research, the evaluation of the project is based on a cost-benefit analysis of the increase in educational attainment. The social benefit is estimated by determining the number of people affected and the social benefit per person affected, and the social discount rate is determined using two types of elasticity estimates. The results suggest that a greater allocation of public resources to child protection provision not only benefits the individuals concerned, but can also result in a positive net present value investment for society as a whole.
