Social Policies for a Recovery

The fallout from the global economic downturn of 2008-09 is a continuing source of stress on families and a constraint on government policies. How can social policies contribute to a quick and equitable recovery from the crisis and how can they best respond to the difficulties that households continue to face? What role can and should social policy budgets play in improving the budget outlook of countries facing unsustainable government debt? And how should governments prioritise different areas of social spending when faced with heightened demand for support but, often, much reduced fiscal space? This paper addresses these questions in light of countries' experiences during the most recent and earlier economic downturns.economic crisis, social policy, redistribution, unemployment, government spending

The Navier-Stokes equations coupled with the energy conservation equation are solved by means of a finite-volume/level-set method. Some numerical examples including thermocapillary motion of single and multiple fluid particles are computed by means of the present method. The results are compared with analytical solutions and numerical results from the literature as validations of the proposed model.Peer ReviewedPostprint (published version
