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...

Applied econometrics has recently emphasized the identification of causal parameters for policy analysis. This revolution has yet to fully propagate to the field of regional science. We examine the scope for application of the matching approach – part of the modern applied econometrics toolkit...

This paper investigates the effects of public investment in infrastructure on private output for Germany. Using a multivariate framework we explore the impact of a diverging selection of variables on the ensuing estimates and document confidence intervals computed following the bootstrap...

Drawing on panel data from Germany, this paper estimates the relationship between charging infrastructure and the uptake of electric vehicles (EVs). We specify models with fixed effects and instrumental variables to gauge the robustness of our findings in the face of alternative channels through...

Emission-free hydrogen (H2) is crucial to decarbonize energy supply and to tackle the climate crisis. To unlock the potential of H2, pipelines infrastructures and related investments are required to enable trade. However, it is uncertain what future H2 infrastructure will be needed. The paper...

For spatial data with a sufficiently long time dimension, the concept of global cointegration has been recently included in the econometrics research agenda. Global cointegration arises when non-stationary time series are cointegrated both within and between spatial units. In this paper, we...

The literature on growth theory is rich with models attempting to explain growth differences among countries. Several variables have been proposed many of which were found to be positively related to growth. However, a major problem with these models is that the factors explaining growth are...

I use German administrative data for 2001-2010 to analyse the impact of urbanization and firm characteristics on wage growth of workers. I find a statistically highly significant higher within-job wage growth rate for workers in counties with a higher population density. This provides evidence...

In many European countries the number of employees hired via temporary work agencies has increased considerably over the past two decades, up to around 2% of the total workforce in the European Union today. Different studies have found the demand for agency employment to precede GDP growth. This...
