Abstract
In this article I argue that contractarian theory is a fruitful approach for dealing with questions of legitimacy in light of globalisation. I try to point out that impaired conditions for providing collective goods in nation-states do not call the legitimacy of globalisation into question, even if the provision of such goods meets with consent amongst the citizens of the nation-state. The need to raise taxes as a consequence of the transfer of mobile resources to other countries can indicate the existence of state activities which lack legitimacy from the contractarian perspective. However, the impossibility of applying the exclusion principle in providing collective goods indeed entails legitimatory problems of globalisation. In this respect, a need for international agreements exists. Nevertheless, unilateral attempts by nation-states to withraw the domestic economy from global influences can interfere with the welfare of other collectives and they therefore lack legitimacy, a moral consequence which is in danger of being neglected even from a contractarian approach.
