Show moreThis thesis contains four empirical studies on the effects of social protection. In the first two studies, I use administrative microdata and employ quasi-experimental methods in which I compare a treatment group with a control group. Study 1 concludes that mandatory activation programs for young welfare recipients do not contribute to employment or to enrollment in education during an economic downturn, but are harmful to income protection. Study 2 concludes that the unemployment shock of a male partner has a large and persistent effect on household income and only 2-5% of this income loss is compensated by increases in female partner’s earnings from work. The last two studies use OECD panel data and employ international comparative research methods. Study 3 concludes that constitutional rights to social security have a positive effect on social expenditure, which is larger for expenditure targeted at the unemployed, a group that is perceived as less deserving by the public opinion compared to the elderly or disabled. Study 4 concludes that Social expenditure reduces poverty and inequality without being harmful for GDP growth. Targeted schemes are most effective in reducing poverty, while social expenditure types with a universal character are more effective in reducing inequality. Show less
