Research Expertise
Description
I am a macroeconomist interested in research questions from different fields of macroeconomics. 1. Intersection of macroeconomics and labor economics: I am interested in different forms of technical change and their implications for the labor market. In the most recent paper, I examine in a theoretical framework how skill-biased technical change affects the task content of production and how this in turn impacts the wage-setting behavior of labor unions, and ultimately income inequality. The proposed framework combines for the first time in the literature the task approach, labor unions, and search frictions in the labor market. In a current project, I build upon the expertise of the previous work and analyze within an extended theoretical framework the impact of Hartz IV reforms on the German labor market using the task-based approach. In another recent project, I examine the role of automation threat in the unions' wage-setting behavior using robot data from the International Federation of Robotics and the rich administrative linked employer-employee dataset of the Institute for Employment Research in Germany. 2. Empirical macroeconomics, especially business cycle analysis, seasonal adjustment, and the detection of structural breaks: * In two contributions, I propose new methods for the analysis of the cyclical behavior of real wages. This research question is highly relevant from the economic policy perspective since empirical results provide valuable insights into the wage and price dynamics for monetary policy. Moreover, an empirical investigation is also important from the perspective of theoretical macroeconomics as different theories deliver different predictions on the procyclical or anticyclical pattern of real wages. * In two further articles, I develop innovative methods that deliver timely and precise business cycle forecasts that play a key role for policy makers, such as central banks. Other three publications related to business cycle analysis offer solutions when the underlying time series display outliers, structural breaks and seasonal patterns. This aspect is important inasmuch as macroeconomic series should be in the first step adjusted for irregular movements and seasonal fluctuations before the cyclical properties are examined. 3. International economics, especially global value chains (GVCs) The focus of this research is the question how intersectoral and international linkages influence unit labor costs and thereby the competitiveness of industries and countries, or affect labor market outcomes when GVCs are recorded correctly. Moreover, the analysis of GVCs offers potential for business cycle analysis in that it provides a micro foundation for the international transmission and synchronization of business cycles.Recognition
