This note exhibits sufficient conditions concerning the skills of old workers ruling out overaccumulation stationnary equilibria in an OLG model with productive capital. Using a Cobb-Douglas economy, we show that such conditions seem to be largely fullfilled in the industrialized countries.

In this paper, we study a notion of sufficient input, i.e. input that allows to produce at least one unit of output when the other inputs are fixed at any positive level. We show that such an input allows to produce any positive amount of production. The main property of sufficient inputs is as...

This note presents a model in which pension funds, by holding a significant share of capital assets, can exert a non competitive behavior on labor market. This leads to lower wages and higher capital returns, and can reduce capital accumulation and long-run welfare.
