We study the impact of agglomeration effects on firms’ total factor productivity (TFP) for industry groups defined by technology intensity. This allows for non-uniform effects on firms depending on their technological level. We find that urban economies have the largest impact on firm productivity in high-technology industries, while they have no effectin low-technology industries. For firms in the ...
This paper re-evaluates the US external deficit which has considerably widened over the 1990s. US safe asset provision to the rest of the world is the dominant explanation for the persistent nature of the US external deficit. We suggest that apart from the safe asset hypothesis, there is an important role for technology shocks originating in US multinational companies that have a strong foreign direct ...
This paper investigates the elusive role of productivity heterogeneity in new trade models in the trade and environment nexus. We contrast the Eaton-Kortum and the Melitz models with firm heterogeneity to the Armington and Krugman models without heterogeneity. We show that if firms have a constant emission share in terms of sales — as they do in a wide range of trade and environment models — the three ...
Der Beitrag untersucht die Rolle der Sozialpartnerschaft zur Reduzierung von Treibhausgasemissionen in Mitgliedsstaaten der Europäischen Union. Einerseits können die Sozialpartner dazu beitragen den Übergang zu niedrigeren Emissionen zu erleichtern, indem sie mit den betroffenen Arbeitnehmern über die Kosten und den Nutzen von Maßnahmen zur Verringerung des Klimawandels verhandeln. Andererseits ist ...
We contribute to the research on gender representation in economics by documenting the share of women among economists in a variety of leadership positions in the academic, but also in the private and public sectors, both globally and by region. For the years 2019 to 2023, we find women economists’ representation overall to be low in all sectors and no clear-cut trends over time. In academia, we find ...
Large parts of the existing natural gas distribution networks must be decommissioned due to the decarbonization of the heat supply. However, there are neither regulatory nor economic incentives for the gas network operators to do so and delaying the decommissioning could be expensive for the remaining customers. This Weekly Report analyzes to what extent municipalities can partially decommission the ...
