Firms in developed countries face increasing shortages of young workers. This paper studies the importance of young workers, particularly vocational trainees, for firm technology investments. Leveraging exogenous variation in trainee supply caused by an education reform in Germany in 2001, I...

This paper investigates a unique policy designed to maintain employment during the privatization of East German firms after the fall of the Iron Curtain. The policy required new owners of the firms to commit to employment targets, with penalties for non-compliance. Using a dynamic model, we...

Production functions provide a mapping from the firms' input quantity and productivity to output quantity. This mapping only generates unbiased estimates if input and output quality variation within and between observation units is accounted for. I review and classify state-of-the-art methods to...

This paper examines whether information technology (IT) and decentralized work organization are complementary only for large firms or also for smaller firms. Empirical evidence, which suggests complementarity between IT and decentralization, is mainly based on large firms. Using data from a...

Increasing energy efficiency is one of the main goals in current German energy and climate policies. We study the determinants of energy efficiency in the German manufacturing sector based on official firm-level production census data. By means of a stochastic frontier analysis, we estimate the...

Although information and communication technologies (ICT) consume energy themselves, they are considered to have the potential to reduce overall energy intensity within economic sectors. While previous empirical evidence is based on aggregated data, this is the first large-scale empirical study...

I study the causal effect of the European Union Emissions Trading System (EU ETS) on the productivity of German manufacturing firms. Using administrative firm-level data, I estimate robust production functions for narrowly defined industries. This approach allows for an endogenous dynamic...

This paper examines whether information technology (IT) and decentralized work organization are complementary only for large firms or also for smaller firms. Empirical evidence, which suggests complementarity between IT and decentralization, is mainly based on large firms. Using data from a...

Drawing on a longitudinal database of Belgian firms over the years 2014-2020, this study investigates the joint effect of R&D grants and R&D tax credits on R&D inputs and innovation outputs. We estimate Conditional Difference-in-Difference (CDiD) models and apply both treatment effects...

Governments can support the green transition through green public procurement. Despite its strategic importance, the impact of this policy on firms remains unclear. Using US data, this paper provides the first empirical analysis of the causal effects of green contracts on corporate environmental...
