The seminar will be devoted to the consequences for social security of the financial and economic crisis in a changing world and will address the following questions: How has the social security sector responded? To what extent the crisis is placing an additional burden on systems’ finances? Have social security systems succeeded in dealing effectively with the negative impacts of the crisis? Have the reforms of the past few years, including activation measures and changes to pensions and healthcare systems, proven effective? What lessons can be learnt for the future? The crisis has also made it apparent that today’s societies will need to realign policies relatively quickly in order to protect the (global) environment and safeguard social cohesion, and to be able to cope adequately with growing migration flows. The seminar will focus on the role that social security might play in this respect, including addressing what kind of reforms are required and whether it is possible to identify best practices. The results of ISSA research on the impact of the crisis will be among the topics on the agenda.
