Superneutrality is demonstrated to no longer hold in the Sidrauski model as soon as agents are heterogenous with regard to their productivity. However, quantitative effects of inflation on the capital stock are found to be rather small.

Ýmrohoroðlu, Ýmrohoroðlu and Joines [1995, A life-cycle analysis of Social Security, Economic Theory, vol. 6, 83-114] show that the optimal replacement ratio of the payas-you-go public pension system in the US economy amounts to 30%. We extend their analysis to a model that 1) replicates the...

In most OECD countries, unemployment benefits are tied to individual previous labor earnings. We study the progressivity of this indexation with regard to its effects on employment, output, and welfare in a calibrated general equilibrium model with search unemployment. Employment varies...

Superneutrality is demonstrated to no longer hold in the Sidrauski model as soll as agents are heterogenous with regard to their productivity. However, quantitative effects of inflation on the capital stock are found to be rather small.

Recent work on money and endogenous growth finds modest welfare costs of inflation. Furthermore, high inflation reduces the growth rate. We present a monetary endogenous growth model with labor market frictions in the form of search unemployment which is calibrated for the US economy....

In many OECD countries, e.g. in Germany, France, or the UK, unemploy-ment compensation consists of unemployment insurance and unemployment assistance. Unemployment assistance is provided subsequent to the expiration of entitlement to unemployment insurance and is lower. The effects of this...

We introduce intergenerational transfers into a general equilihrium life-cycle model in order to explain observed levels of wealth heterogeneity. In our overlapping generations model, heterogenous agents face uncertain lifetime and leave both accidental and voluntary bequests to their cinldren....

We study the effect of a declining labor force on the incentives to engage in labor-saving technical change and ask how this effect is influenced by institutional characteristics of the pension scheme. When labor is scarcer it becomes more expensive and innovation investments that increase labor...

According to empirical studies, the life cycle of labor supply volatility exhibits a U-shaped pattern. This may lead to the conclusion that demographic change induces a drop in output volatility. We present an overlapping generations model that replicates the empirically observed pattern and...

Prettner (2019) studies the implications of automation for economic growth and the labor share in a variant of the Solow-Swan model. The aggregate production function allows for two types of capital, traditional and automation capital. Traditional capital and labor are imperfect substitutes...
