There is still hardly any empirical evidence on how divergent broadband technologies, and, by extension, bandwidth levels, influence GDP growth, or on the extent of spatial externalities at a regional level. Our study aims to assess the economic benefits of high-speed broadband networks within...

In the context of EMU fiscal equalization schemes have been proposed as a means to stabilize regions against asymmetric shocks. A theoretical analysis shows that besides reducing the cross-sectional income variance the redistributive element of fiscal equalization causes incentive effects for...

We analyze the effect of the Öresund Bridge, a combined railway and motorway bridge between Swedish Malmö and the Danish capital Copenhagen, on inventive activity in the region of Malmö. Applying difference-in-difference estimation on individual-level data, our findings suggest that the...

The empirical and theoretical literature on long-term relationships in public finance is dominated by two approaches: Fiscal sustainability and Wagner’s law of an increasing state activity. In this paper, we argue that these two relationships should be analyzed simultaneously and not...

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 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 this article, we present a model that can account for the changes in the German current account balance since the 2000s. Our results suggest that an array of structural tax and labor market reforms (Agenda 2010), population aging and pension reforms led to an increase in the household savings...

We simulate the fiscal stimulus packages set up by the German government to allevi-ate the costs of the COVID-19 pandemic in a dynamic New Keynesian multi-sectorgeneral equilibrium model. We find that, cumulated over 2020-2022, output lossesrelative to steady state can be reduced by more than 4...

This paper shows that demographic change plays an important role in the formation of a country's net foreign asset position. An ageing population both lowers the demand and increases the supply of capital in an economy. Fewer workers reduce the required capital stock. As a longer life span leads...
