This paper develops a search and matching model with hierarchical firms, human capital accumulation, internal promotions and on-the-job search. At the time of their market entry firms maximize present value of profits with respect to their promotion rule. Workers who are eligible for promotion...

We study optimal promotion decisions of hierarchical firms, with one junior and one senior managerial position, which interact in a search and matching labour market. Workers acquire experience over time while being employed in a junior position and the firm has to determine the experience level...

In this paper I evaluate the effects of a regional experiment that reduced payroll-taxes by 3-6 percentage points of the firm's wage sum in Northern and Eastern Finland. I estimate the effect of the payroll-tax reduction on firms' employment, wage sum and profits, and on workers hourly pay and...

Using the introduction of fixed long-term unemployment benefits in Germany in 2005 as a unique experiment we find strong evidence that lower unemployment benefit has an adverse effect on wages. We use panel data to identify and estimate the effect of this structural break. In western Germany the...

A sizable literature documents that displaced workers suffer substantial negative consequences in the labor market and health. These effects may extend to the partner or spouse through household decision-making. Using administrative data of all workers and firms matched to mortality and patient...

The Austrian Beveridge curve shifted in 2014, leading to ongoing academic discussions about the reasons behind this shift. While some have argued that the shift was caused by a supply shock due to labour market liberalization, others have stated that matching efficiency decreased. Using a new...

Empirical studies show that women are under-represented in highly paid top management positions of firms (glass-ceiling effect) which could be a cause of the gender wage gap. In order to study women's career paths, we develop a search and matching model where job ladders consist of three...

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...

I investigate causal machine learning (CML) methods to estimate effect heterogeneity by means of conditional average treatment effects (CATEs). In particular, I study whether the estimated effect heterogeneity can provide evidence for the theoretical labour supply predictions of Connecticut's...
