The European Green Deal, initiated by the EU Commission, is a package of measures aimed at decarbonization and sustainable economic development with the goal of making the European Union climate neutral by 2050. To achieve this goal, the emission reductions target must be increased from 40 percent to 65 percent compared to 1990 levels, as the model calculations in this Weekly Report show. Fossil and ...
Dieser Gastbeitrag von Dorothea Schäfer erschien am 5. Juli 2020 im Tagesspiegel. Mehr Sein als Schein ist in den letzten 30 Jahren aus der Mode gekommen, fatalerweise und trotz des Platzens der New-Economy-Blase um die Jahrtausendwende.

This paper provides the first comprehensive review of the empirical and theoretical literature on the determinants of the elasticity of substitution between capital and labor. Our focus is on the two-input constant elasticity of substitution (CES) production function. We start by presenting four concise observations that summarize the empirical literature on the estimation of σ. Motivated by these observations, ...
In recent years, the phenomenon of common ownership by institutional investors has sparked considerable debate among scholars about its impact on competition and companies’ corporate governance. This study analyses some specific features of common ownership by institutional investors in the European banking sector. It also examines closely the tension between competition policy and corporate governance ...
Combined heat and power (CHP) can achieve fuel efficiencies of up to 90% and is thus considered as economically advantageous and ecologically sound compared to uncoupled power and heat generation. This advantage is exploited only if CHP plants are operated as much as possible at their optimal operation point. Increasing penetration by variable renewable energy sources and more flexible technologies ...
Policymakers have implemented a wide range of non-pharmaceutical interventions to fight the spread of COVID-19. Variation in policies across jurisdictions and over time strongly suggests a difference-in-differences (DD) research design to estimate causal effects of counter-COVID measures. We discuss threats to the validity of these DD designs and make recommendations about how researchers can avoid ...
