Using the German IAB Job Vacancy Survey, we look into the black box of recruiting intensity and hiring practices from the employers' perspective. Our paper evaluates three important channels for hiring -namely vacancy posting, the selectivity of hiring (labor selection), and the number of search...

While there is a wealth of literature dealing with the spatial nature of knowledge and its transferral, I argue that the underlying mechanisms have not been sufficiently understood. Existing research relating the geography of inflows to firm productivity does not adequately address firm and...

In Germany, there is no trade union membership wage premium, while the membership fee amounts to 1% of the gross wage. Therefore, prima facie, there are strong incentives to free-ride on the benefits of trade unionism. We establish empirical evidence for a private gain from trade union...

Agricultural production is an important source of income and employment for developing countries, yet it is the cause of serious environmental problems. Though ECO-labels appear as a promising alternative to control the negative effects of agriculture on the environment and to increase the...

Universities are increasingly seen as engines for regional innovation and economic growth. Some famous high-tech regions have developed on the basis of universities, for example Silicon Valley in California, Greater Boston in Massachusetts, or the Research Triangle in North Carolina. In these...

It is difficult to estimate the impact of geographic clustering on productivity because of endogeneity issues. I use birthplace-cluster distance as an instrumental variable for the incidence of clustering of prominent classical composers born between 1750 and 1899. I find that geographic...

The aim of this paper is to develop a spatial model that explicitly incorporates the different types of knowledge spillovers taking place in cities and to show how they affect the migration decision of individuals and the size of cities. We use a static general equilibrium framework with two...

This paper revisits a classical inquiry by addressing the question of localization and urbanization economies. We propose that specialization and diversity may offer externalities operating at different spatial scales. Using high-resolution geo-coded plant-level panel data for Swedish cities...

This paper applies functional regression to precise geo-coded register data to measure productivity spillovers from high-skilled workers. We use a smoothing splines estimator to model the spatial distribution of high-skilled workers as continuous curves. Our rich panel data allows us to address...

The economic impact of Artificial Intelligence (AI) is studied using a (semi) endogenous growth model with two novel features. First, the task approach from labor economics is reformulated and integrated into a growth model. Second, the standard represen- tative household assumption is rejected,...
