Empirically, the income share is procyclical for the low-income groups and acyclical for the top 5%. We find that business cycle models should consider overlapping generations and elastic labor supply in order to replicate this finding

The effect of a permanent change of inflation on the distribution of wealth is analyzed in a general equilibrium OLG model that is calibrated with regard to the characteristics of the US economy. Poor agents accumulate savings predominantly in the form of money, while rich agents participate in...

We study the incentives that governments have to protect intellectual property in a trading world economy. We consider a world economy with ongoing innovation in two countries that differ in market size and in their capacities for innovation. We associate the strength of IPR protection with the...

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.

The conditional equity premium in the model with production is often approximated by assuming a jointly log-normal distribution of the marginal rate of substitution in consumption and the marginal productivity of capital. We show that, for standard parameterization, this premium is about one...

The paper analyzes the dynamic effects of a total factor productivity shock and an interest rate risk premium shock in a highly indebted open economy. In contrast to the standard open economy framework, search unemployment and wage bargaining are introduced. We find that a negative total factor...

De Paoli, Scott, and Weeken (2010, Asset pricing implications of a New Keynesian model. Journal of Economic Dynamics and Control 34, 2056-73) study equity and bonds prices in a New Keynesian model with sticky nominal prices. This note argues that their model generates a behavior of the labor...

“Race-to-the-bottom” deregulation is to be expected when markets operate across the borders of countries that independently choose and enforce labor policies. Less obviously, in pre-crisis EMU reforms of labor market policies were uneven and related to international imbalances. That pattern...

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...

We consider optimal monetary policy in a model that integrates credit frictions in the standard New Keynesian model with sticky prices and wages as well as adjustment costs of capital. Different from traditional models with credit frictions such as Carlstrom and Fuerst (1998), the model is able...
