Inflation Concerns and Green Product Consumption: Evidence from a Nationwide Survey and a Framed Field Experiment
Sabrina Jeworrek, Lena Tonzer
IWH Discussion Papers,
No. 10,
2024
Abstract
Promoting green product consumption is one important element in building a sustainable society. Yet green products are usually more costly. In times of high inflation, not only budget constraints but also the fear that prices will continue to rise might dampen green product consumption and, hence, limit the effectiveness of exerted efforts to promote sustainable behaviors. To test this suggestion, we conducted a Germany-wide survey with almost 1,200 respondents, followed by a framed field experiment (N=500) to confirm causality. In the survey, respondents’ stated “green” purchasing behavior is, as to be expected, positively correlated with concerns about climate change. It is also negatively correlated with concerns about future inflation and energy costs, but after controlling for observable characteristics such as income and educational level only the correlation with concerns about future prices remains significant. This result is driven by individuals with below-median environmental attitude. In the framed field experiment, we use the priming method to manipulate the saliency of inflation concerns. Whereas sizably relaxing the budget constraint (i.e., by 50 percent) has no impact on the share of organic products in participants’ baskets, the priming significantly decreases the share of organic products for individuals with below-median environmental attitude, similar to the survey data.

Climate Stress Tests, Bank Lending, and the Transition to the Carbon-neutral Economy
Larissa Fuchs, Huyen Nguyen, Trang Nguyen, Klaus Schaeck
IWH Discussion Papers,
No. 9,
2024
Abstract
We ask if bank supervisors’ efforts to combat climate change affect banks’ lending and their borrowers’ transition to the carbon-neutral economy. Combining information from the French supervisory agency’s climate pilot exercise with borrowers’ emission data, we first show that banks that participate in the exercise increase lending to high-carbon emitters but simultaneously charge higher interest rates. Second, participating banks collect new information about climate risks, and boost lending for green purposes. Third, receiving credit from a participating bank facilitates borrowers’ efforts to improve environmental performance. Our findings establish a hitherto undocumented link between banking supervision and the transition to net-zero.

Klimastresstests, Kreditvergabeverhalten der Banken und der Übergang zur klimaneutralen Wirtschaft
Larissa Fuchs, Huyen Nguyen, Trang Nguyen, Klaus Schaeck
Wirtschaft im Wandel,
No. 1,
2024
Abstract
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.

Climate Change Exposure and the Value Relevance of Earnings and Book Values of Equity
Iftekhar Hasan, Joseph A. Micale, Donna Rapaccioli
Journal of Sustainable Finance and Accounting,
March
2024
Abstract
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.
