This note generalizes the Solow-Stiglitz efficiency condition for natural resources to the problem of fossil fuel extraction with a greenhouse effect. The generalized optimality condition suggests that the greenhouse effect implies overextraction in the sense of leaving future generations a...

In order to quantify these effects, we develop a computational general equilibrium model. We feed this multi-country overlapping generations model with detailed long-term demographic projections for seven world regions. Our simulations indicate that capital flows from fast-aging regions to the...

The upcoming demographic crisis in Germany demands fundamental reforms of the pension system. In a democracy, reforms are, however, only feasible when they are supported by the majority of the electorate. To determine whether the majority is in favor of reforms of the pension system, we...
