Kann die Bankenaufsicht den Übergang zu einer kohlenstoffneutralen Wirtschaft unterstützen, indem sie die Kreditvergabe der Banken an Unternehmen beeinflusst? Dieser Beitrag untersucht die Kreditvergabe der Banken vor und nach dem weltweit ersten Klimastresstest in Frankreich und die Reaktion der kreditnehmenden Unternehmen. Die dem Stresstest unterworfenen Banken geben kohlenstoffintensiven Unternehmen mehr Kredite. Zugleich verlangen sie ihnen aber höhere Zinssätze ab. Die kohlenstoffintensiven Kreditnehmer, deren Banken sich dem Klimastresstest unterzogen haben, verpflichten sich eher zu ehrgeizigen Emissionszielen und integrieren eher Umweltaspekte in die Bewertung von Investitionsprojekten. Jedoch reduzieren sie weder direkt ihre Kohlenstoffemissionen noch beenden sie Beziehungen zu klimaschädlichen Lieferanten. Die Studie belegt somit einen kausalen Zusammenhang zwischen Klimastresstests der Banken und der Verringerung des Transitionsrisikos der Kreditnehmer.

We investigate whether a firm’s exposure to climate change, as proxied by disclosures during quarterly earnings conference calls, provides forward-looking information to investors regarding the long-term association of stock prices with current earnings and the book values of equity. Following a key regulatory mandate around the formation of the cap-and-trade program to reduce emissions related to climate change, firms’ climate change exposure decreases the association between current earnings and stock prices while increasing the relevance of book values of equity (i.e., historical earnings). However, these relationships flip when the sentiment around climate change exposure is negative, suggesting that the risks related to climate change exposure provide forward-looking information to investors when they evaluate the ability of current earnings to predict firm values. Such a relationship is stronger for new economy firms and is sensitive to conservative accounting. We also observe that the inclusion of climate change disclosure to our models improves the joint ability of earnings and book values to predict stock prices.

Climate change and inequality are critical and interrelated defining issues for this century. Despite growing empirical evidence on the economic incidence of climate policies and impacts, mainstream model-based assessments are often silent on the interplay between climate change and economic inequality. For example, all the major model comparisons reviewed in IPCC neglect within-country inequalities. Here we fill this gap by presenting a model ensemble of eight large-scale Integrated Assessment Models belonging to different model paradigms and featuring economic heterogeneity. We study the distributional implications of Paris-aligned climate target of 1.5 degree and include different carbon revenue redistribution schemes. Moreover, we account for the economic inequalities resulting from residual and avoided climate impacts. We find that price-based climate policies without compensatory measures increase economic inequality in most countries and across models. However, revenue redistribution through equal per-capita transfers can offset this effect, leading to on average decrease in the Gini index by almost two points. When climate benefits are included, inequality is further reduced, but only in the long term. Around mid-century, the combination of dried-up carbon revenues and yet limited climate benefits leads to higher inequality under the Paris target than in the Reference scenario, indicating the need for further policy measures in the medium term.

Die EU hat mit dem „Fit for 55“-Paket zwei große klimapolitische Ziele festgelegt: die Senkung der Treibhausgasemissionen um 55% bis zum Jahr 2030 und Treibhausgasneutralität ab dem Jahr 2050. Im Rahmen des EU-Horizon-2020-Projekts ENTRANCES werden die gesellschaftlichen Effekte der Dekarbonisierung und besonders des Kohleausstiegs in verschiedenen europäischen Regionen interdisziplinär analysiert und darauf basierend Handlungsempfehlungen für die Politik abgeleitet. Der vorliegende Beitrag stellt erste analytische Ergebnisse vor.

We examine a corporate governance role of local culture via its impact on consumer behavior following corporate scandals. Our proxy for culture is the presence of local Protestantism. Exploiting the unexpected nature of the Volkswagen (VW) diesel scandal in September 2015, we show that new registrations of VW cars decline significantly in German counties with a Protestant majority following the VW scandal. Further survey evidence shows that, compared to Catholics, Protestants respond significantly more negatively to fraud but not to environmental issues. Our findings suggest that the enforcement culture in Protestantism facilitates penalizing corporate fraud.

In recent years, the impacts of climate change become increasingly evident, both in magnitude and frequency. The design and implementation of adequate climate adaptation policies play an important role in the macroeconomic policy discourse to assess the impact of climate change on regional and sectoral economic growth. We propose different modelling approaches to quantify the socio-economic impacts of climate change and design specific adaptations in three emerging market economies (Kazakhstan, Georgia and Vietnam) which belong to the areas that are heavily exposed to climate change. A Dynamic General Equilibrium (DGE) model has been used for Vietnam and economy-energy-emission (E3) models for the other two countries. Our modelling results show how different climate hazards impact the economy up to the year 2050. Adaptation measures in particular in the agricultural sector have positive implications for the gross domestic product (GDP). However, some adaptation measures can even increase greenhouse gas emissions. In addition, the focus on GDP as the main indicator to evaluate policy measures can produce welfare-reducing policy decisions.
