Pensionomics - On the Role of PAYGO in Pension Portfolios

Pensionomics puts forward a portfolio perspective on the combination of funded and unfunded pension arrangements. In a second-best type argument it is formally shown that a Pay-As-You-Go pension system can substitute the tradability of human capital. While this ideal form of diversification can not be implemented due to the imperfection of capital markets, one can design a typical Pay-As-You-Go system in such a way that it allows for the same intertemporal consumption allocations as the first-best solution.
