Working time account is an organization tool that allows firms to smooth their demand for hours employed. Descriptive literature suggests that working time accounts are likely to reduce layoffs and inhibit increases in unemployment during recessions. In a model of optimal labour demand I show...

We evaluate the impact of a major European state aid programme for broadband deployment applied to rural areas in the German state of Bavaria in the years 2010 and 2011. Using matched difference-in-differences estimation strategies, we find that aided municipalities have – depending on...

Are entrepreneurs liquidity constraint? Using quasi-random housing wealth variation resulting from communist era decisions, we argue yes, as we find that wealthier East Germans are more likely to become self-employed after reunification. In the literature, no such strong relationship was found...

This paper analyses how demographic changes of the labour force affect labour demand. Do firms adjust their hiring behaviour to an ageing society? Combining data at the firm level and the administrative district level, we analyse the hiring behaviour of firms. Our findings suggest that firms...

The highly dynamic nature of the COVID-19 crisis poses an unprecedented challenge to policy makers around the world to take appropriate income-stabilizing countermeasures. To properly design such policy measures, it is important to quantify their effects in real-time. However, data on the...

This paper estimates the effect of innovation on employment at the firm level. Our uniquely long innovation panel data set of German manufacturing firms covers more than 20 years and allows us to use various innovation measures. We can distinguish between product and process innovations as well...

For a long time globalization could be seen everywhere but in gravity estimates. We offer evidence how globalization affects manufacturing trade over the period 1986-2006 and show that, on average, the effect of distance has fallen whereas the effects of proximity and regional trade agreements...

We capitalize on the latest developments in the empirical structural gravity literature to revisit the question of whether and how much does GATT/WTO membership affect international trade. We are the first to capture the non-discriminatory nature of GATT/WTO commitments by measuring the effects...

Using a new, global data base covering the years 1950 to 2015, we study the impact of sanctions on international trade and welfare. We make use of the rich dimensionality of our data and of the latest developments in the structural gravity literature. Starting with a broad evaluation by sanction...

Geography, economic size, or common history, help predicting signed regional trade agreements (RTAs). However, not all signed RTAs are “natural” according to economic determinants. En-dogeneity and general equilibrium effects of RTAS are the two mechanisms addressed in this paper. We...
