Research on the effects of informal child fostering arrangements on the welfare of the children involved highlights cross-country disparities. Why may there be differences across countries with regard to the effects of informal child fostering arrangements? If in all countries reporting a high...

We assess whether global social welfare has improved in the last decades despite (or because of) the substantial increase in global population. We use for this purpose a relatively unknown but simple and attractive social evaluation approach called critical-level generalized utilitarianism...

Much current debate focuses on the role of growth in alleviating poverty. However, the majority of computable general equilibrium (CGE) models used in poverty and inequality analysis are static in nature. The inability of this kind of model to account for growth (accumulation) effects makes them...
