This paper presents an efficient solution method for solving stochastic overlapping generations (S-OLG) models. We use the Chebyshev parameterized expectation algorithm (C-PEA) developed by Christiano and Fisher (2000) to solve the life cycle block of S-OLGs. The method is well suited for this...

We compare the macroeconomic effects of a fully funded individual defined contribution (IDC) pension scheme, an unfunded pay-as-you-go (PAYG) system, and a collective defined contribution (CDC) regime. Under the latter, contributions of workers from a given cohort are invested in capital markets...

The paper gives conditions for effi ciency and ineffi ciency of equilibrium allocations in an overlapping-generations model with a constant rate of population growth and with multiple assets, but without labour. Optimal portfolio choice implies that, for any period and history up to that period,...

This expository note uses Hilbert's "infinite hotel", a hotel where one can always find place for another guest even if the hotel is already full, to illustrate the failure of the First Welfare Theorem in "large-square" economies that have infinitely many participants as well as infinitely many...
