This paper analyses whether the severe demographic change in Germany causes its high current account surpluses. An ageing population both increases the supply and lowers demand of capital in an economy. Due to a longer life span individuals save more. Fewer workers reduce the optimal capital...

Ageing of most societies is driven by two factors: (1) birth rates are declining and (2) people are living longer. These developments have substantial effects on economies and, in particular, on the funding of our living standards in retirement. We develop an overlapping generation model in...

This paper presents an overlapping generations model where agents face labor-income and health risks in order to quantify the macroeconomic and welfare consequences of reform options for the German health insurance system. In addition to labor supply, consumption and savings, households also...
