Germany is considered to be a pioneer of social security systems; nonetheless, globalization and demographic changes have put enormous pressure on them. A solution is not yet in sight as the debate on the future of the German social security systems still lacks consensus. We argue that ideas matter and that the debate can benefit from a deeper reflection on the concept of social security. This objective is pursued along two lines. First, we take a historical perspective and reconstruct the (...) development of Germany's social security systems. Second, we scrutinize from a theoretical perspective how social security is conceptualized in public and theoretical debates. Behind the various positions, we identify four basic ideal types. We then analyze how these ideal types account for the benefits of social security systems and what role they assign to corporations in providing social security. While two ultimately reinforce potential conflicts between different groups in society, the other two ideal types reveal possible benefits for all. The last ideal type actually conceptualizes social security systems as insurance that fosters risky but overall productive investments in human and other forms of capital. Therefore, it can be shown that social security systems are not necessarily threatened by globalization and that incentives exist for corporations to invest in the provision of social security.

Starting point is the thesis that economics - as well as other social sciences - is imperialistic with regard to the area of its subject, but not with regard to its approach. Underlying economics is the following schema: Try to explain under the presumption that actors maximize their expected utility under constraints. Conditions and possibilities of interdisciplinary research within all sciences being considered imperialistic are discussed according to this schema. Theoretical guide-lines are provided by the systematic connection of ‘problem’ and (...) ‘schema’, as well as the concept of ‘fruitfulness’ as primary criterion of judgement. (shrink)
