The energy transition requires substantial amounts of metals, including copper, nickel, cobalt, and lithium. Are these metals a bottleneck? We identify metal-specific demand shocks, estimate supply elasticities, and study the price impact of the transition in a structural scenario analysis. Prices of these four metals would reach previous historical peaks but for an unprecedented, sustained period ...
In this paper we analyse the association between maternal well-being and child development at different ages. We use data from the German Socio-Economic Panel (SOEP) which captures maternal life satisfaction and numerous cognitive and non-cognitive child development outcomes. We identify a strong positive association between mothers’ life satisfaction and their children’s development when these are ...
Job levels summarize the complexity, autonomy, and responsibility of task execution. Conceptually, job levels are related to the organization of production, are distinct from occupations, and can be constructed from data on task execution. We highlight their empirical role in matched employer-employee data for life-cycle wage dynamics, refine a task-based view of wage determination, and demonstrate ...

Our paper contributes to the discussion about Europe’s digital sovereignty. We analyze the relationship between firm performance and the diversification of sourcing countries for imported ICT goods. The analysis is based on administrative data for 3888 German manufacturing firms that imported ICT goods in the years 2010 and 2014. We find that firms that diversify the sourcing of ICT goods across multiple ...
Die globale Armut zu bekämpfen, verursache kaum zusätzliche Emissionen, zeigt eine Studie. Das größte Einsparpotenzial haben die reichsten Länder. Auf sie kommt es an. Ein häufiger Einwand gegen Klimaschutzmaßnahmen hierzulande ist, die Anstrengungen brächten nicht viel, wenn Menschen in anderen Ländern nicht auch ihre Emissionen reduzieren würden. Der neue Climate Inequality Report 2023 entkräftet ...
This paper deals with the data generation process implemented for an analysis of the impact of the 9-Euro ticket on mode choice. We discuss the assumptions made and procedures used to process a raw dataset that is based on GPS traces of individuals’ movements and on survey data into the choice-set for a discrete choice model. Several steps of cleaning and merging are described in order to a) obtain ...
