Using a three-period overlapping generations economy framework, we characterize an intergenerational welfare state with endogenous education and pension under voting. We show that although politically establishing Pay-As-You-Go (PAYG) social security in isolation in a dynamically efficient economy will always reduce the capital investment and therefore the social welfare as expected, in contrast politically implementing education-pension policy package instead can improve both human and physical capital accumulation and social welfare over laissez faire.
