This study uses Fehr, Jokisch, and Kotlikoffs̕ (2004a) dynamic general equilibrium model to analyze the effects of changes in fertility and mortality on the developed worlds̕ demographic transition. The model features three regions the U.S., Japan, and the EU-15 and incorporates age- and...

We provide evidence that lower fertility can simultaneously increase income per capita and lower carbon emissions, eliminating a trade-off central to most policies aimed at slowing global climate change. We estimate the effect of lower fertility on carbon emissions accounting for the fact that...

We model the optimal reaction of a public PAYG pension system to demographic shocks. We compare the ex-ante first best and second best solution of a Ramsey planner with full commitment to the outcome under simple third best rules that mimic the pension systems observed in the real world. The...
