Although demographic change leaves pay-as-you-go pension systems unsustainable, reforms, such as a higher pension age, are highly unpopular. This contribution looks into the role of intrinsic motivation as a driver for pension reform preferences. Theoretical reasoning suggests that this driver should be relevant as it decreases the subjective costs of a higher pension age. We test this key hypothesis on the basis of the German General Social Survey (ALLBUS). The results are unambiguous: in addition to factors such as age or education, the inclusion of intrinsic work motivation helps improving our prediction of an individual's reform orientation.
