This paper studies how population aging affects macroeconomic performance and the effectiveness of macroeconomic policies. By using a new Keynesian dynamic stochastic general equilibrium model with heterogeneous households, we find that the effectiveness of monetary policy diminishes as...

This paper studies how an aging population affects economic performance and the effectiveness of fiscal and monetary policies. We develop a New Keynesian dynamic stochastic general equilibrium model with heterogeneous households, workers, and retirees. We demonstrate that an increase in the...

This paper studies the impact of tax-financed universal health coverage schemes on macroeconomic aspects of labor supply, asset holding, inequality, and welfare, while taking into account features common to developing economies, such as informal employment and tax avoidance, by constructing a...

We present the estimated large-scale three-region DSGE model GEAR picturing Germany, the Euro Area and the Rest of the world. Compared to existing models of this type, GEAR incorporates a comprehensive fiscal block, involuntary unemployment and a complex international structure. We use the model...

In this paper,we assess the impact ofmajor German structural reforms from1999 to 2008 on key macroeconomic variables within a two-country monetary union DSGE model. Bymany, these reforms, especially the Hartz reforms on the labormarket, are considered to be the root of thereafter observed...

Since the mid-1970s, firm entry rates in the United States have declined significantly. This also holds for other OECD countries over the past years. At the same time, these economies experienced a gradual process of population aging. Applying a tractable life-cycle model with endogenous firm...

In this paper, we assess the impact of major German structural reforms from 1999 to 2008 on key macroeconomic variables. By many, these reforms, especially the Hartz reforms on the labor market, are considered to be the root of observed imbalances in the Euro Area. Our simulations within a...

In a New Keynesian DSGE model with labor market frictions and liquidityconstrained consumers aggregate unemployment is likely to increase due to a non-persistent government spending shock. Furthermore, the group of asset-holding households reacts very differently from the group of...

"Abenomics" refers to the economic policies advocated by Prime Minister Shinzo Abe who became prime minister of Japan for a second time when his party, the Liberal Democratic Party, won an overwhelming majority at the general election in December 2012. Abenomics has "three arrows": (i)...
