Job Market Candidates
Marius Fourné
Marius Fourné is a PhD candidate in Economics at the Halle Institute for Economic Research (IWH) and Martin Luther University of Halle-Wittenberg, where he has been part of the Department of Macroeconomics since 2021.
His job market paper “Cross-Border Transmission of Climate Policies through Global Production Networks”demonstrates that climate policies enacted in one country transmit across borders through supply chains, affecting industries abroad and underscoring the international reach of environmental regulation. These spillovers operate largely through green innovation and the adoption of cleaner inputs, showing how foreign regulation can catalyse technological upgrading and sustained productivity gains beyond national borders. Beyond this work, his dissertation explores how climate policy shapes cross-border capital flows and how globalisation influences productivity growth and labour compensation.
International experience includes a visiting PhD stay at the Paris School of Economics and an internship at the World Trade Organisation in Geneva. His research has been presented at major conferences such as the Central Bank Research Association (CEBRA) Annual Meeting, the International Association for Applied Econometrics (IAAE) Annual Conference, and the European Trade Study Group (ETSG) Conference.
The dissertation is supervised by Professor Oliver Holtemöller and Professor Xiang Li.
Patrick Nüß
Patrick Nüß joined in 2024 the Department of Structural Change and Productivity at the Halle Institute for Economic Research (IWH) as a Postdoctoral Researcher after completing his PhD in Quantitative Economics at Kiel University (summa cum laude). His research covers labour and public economics, combining field and survey experiments with quasi-experimental methods to study how labour-market institutions, management behaviour, and workers’ perceptions shape employment relations.
In his job market paper “Management Opposition, Strikes, and Union Threat”, he presents the first large-scale correspondence experiment measuring employer discrimination against union supporters in Germany, based on 13,000 fictitious job applications. His results indicate that discrimination arises primarily from union threat effects, as employers seek to avoid potential wage increases. His ongoing projects examine workers’ willingness to unionize, the valuation of non-wage amenities, perceptions of inequality in life expectancy, and the cognitive consequences of war.
Patrick has completed research stays at Princeton University, MIT Sloan School of Management, and the UCL Social Research Institute. His dissertation received multiple awards, including the SHUG Doctoral Prize and the GSÖBW Elinor Ostrom Prize, and earned an Honorable Mention at the LERA Dissertation Award.
Alessandro Sardone
Alessandro Sardone is a PhD candidate in Economics at the Halle Institute for Economic Research (IWH) and Martin Luther University of Halle-Wittenberg, where he has been part of the Department of Macroeconomics since 2020.
His job market paper “Road to Net Zero: Carbon Policy and Redistributional Dynamics in the Green Transition” studies how the European Union’s transition to net zero emissions affects output, inflation, and inequality. Using an Environmental DSGE model with heterogeneous households, he shows that carbon taxation depresses output and consumption and raises energy prices, with outcomes depending on how tax revenues are recycled. Progressive transfers reduce inequality but entail higher macroeconomic costs, while subsidies and tax cuts stabilize activity but amplify disparities.
Beyond this work, his dissertation examines how environmental fiscal measures interact with monetary policy and how heterogeneity and uncertainty shape macroeconomic transmission. Other projects analyze the design of monetary policy in economies with green and polluting sectors and contribute to the growing literature linking climate policy to business cycles and inequality.
He was a visiting researcher at Georgia State University in 2024 and contributes to the IWH’s quarterly forecasts on macroeconomic conditions and greenhouse gas emissions. His research has been presented at major international conferences such as AERE, EAERE, and EEA.
His dissertation is supervised by Professor Oliver Holtemöller and Professor Roland Winkler.
