To reach the climate targets, the course towards a climate-neutral society must be set now. However, the current monitoring instruments in the Climate Change Act do not provide sufficient information to policymakers and society on the effectiveness of policy instruments and programs, as they focus exclusively on greenhouse gas reduction targets, which are subject to uncertainty. Moreover, they only ...
Der Beschluss des Bundesverfassungsgerichts zum Klimaschutzgesetz sowie die Verpflichtung zum Erreichen von Klimaneutralität stellen neue Anforderungen an die Politik. Die Weichen für eine klimaneutrale Gesellschaft müssen jetzt gestellt werden. Die derzeit im Klimaschutzgesetz vorgesehenen Monitoringinstrumente sind jedoch nicht ausreichend, um zu erkennen, ob die Politikinstrumente und Programme ...
We consider a Green Public Procurement setting where the procurer provides a bid discount to environment-friendly technologies to foster their use. We assume that, before the auction, firms may switch to green technology via a publicly observable costly investment. We show that investment acts as a signaling device. This mitigates the effect of incomplete information on firms’ costs, thereby triggering ...
We examine the impact of a disclosure mandate for greenhouse gas emissions on firms’ subsequent emission levels and financial operating performance. For UK-incorporated listed firms a carbon disclosure mandate was adopted in 2013. Our difference-in-differences design shows that firms affected by the mandate reduced their emissions by about 8% relative to a control group of European firms. At the same ...
Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices - unit prices on household unsorted waste disposal - on waste demands and social welfare. First, using a unique panel of Italian municipalities with large variation in prices and observables, I show that waste demands are nonlinear. - find evidence of constant elasticities at ...
As COP26 drew to a close earlier this month, almost 200 nations agreed to “phase down” coal power in the coming years. How this is done, for coal and other fossil fuels, will have implications for individuals and communities that depend on these resources for their livelihoods. The case study conducted by DIW Berlin focuses on Germany and the efforts it has undertaken to support ...
Bei der COP26, die Anfang des Monats zu Ende ging, einigten sich fast 200 Staaten darauf, die Kohlekraft in den kommenden Jahren auslaufen zu lassen. Die Art und Weise, wie dies für Kohle und andere fossile Brennstoffe geschieht, wird Auswirkungen auf Einzelpersonen und Gemeinschaften haben, die für ihren Lebensunterhalt auf diese Ressourcen angewiesen sind. Die vom DIW Berlin durchgeführte ...
Air pollution’s influence on cognitive productivity is a highly relevant and not fully understood economic issue. This study provides evidence of an adverse effect of exposure on the productivity of Mexican judicial workers. The empirical strategy approximates productivity with the length of the hearing and infers causality through instrumental variable panel models. Results show that nitrogen dioxides ...
