Description
I am a macroeconomist working at the intersection of three connected areas: macroeconomics and labour economics, empirical macroeconomics and business cycle analysis, and international economics with a focus on global value chains. Macroeconomics of labour markets I study how different forms of technical change affect the labour market through the task content of production, with implications for wages, employment, and income inequality. My theoretical framework was the first in the literature to combine the task approach, labour unions, and search frictions in the labour market. Building on this foundation, my current work extends in three directions: a theoretical analysis of monopolistic firm power and labour"capital task allocation under union bargaining; a study of how AI shocks affect workers of different skill levels under endogenous task allocation; and a project using robot data from the International Federation of Robotics, combined with administrative linked employer"employee data from the IAB, to analyse the role of automation threat in union wage-setting. A further project applies the task-based approach to the German Hartz IV reforms. Empirical macroeconomics: business cycle analysis, seasonal adjustment, structural breaks My published work proposes new methods for analysing the cyclical behaviour of real wages " a question central to monetary policy and to discriminating between competing macroeconomic theories " alongside methods for timely and precise business cycle forecasts of direct relevance to central banks, and methods that handle outliers, structural breaks, and seasonal patterns in macroeconomic time series. This strand continues in a current project decomposing aggregate unemployment into trend and cyclical components using disaggregated rates by gender and age " the first such analysis for Germany, using the SIAB administrative dataset " co-authored with Heiko Stüber and Tommaso Proietti. International economics and global value chains I examine how intersectoral and international linkages influence unit labour costs, the competitiveness of industries and countries, and labour-market outcomes when GVCs are accurately measured. The GVC perspective also provides a micro-foundation for the international transmission and synchronisation of business cycles. My most recent contribution in this strand, currently undergoing a major revision for Review of World Economics, examines international cost competitiveness at the sectoral level through the lens of GVCs.Recognition
