Optimal Monetary Policy in a Two-sector Environmental DSGE Model

No. 18,

Abstract
In this paper, we discuss how environmental damage and emission reduction policies affect the conduct of monetary policy in a two-sector (clean and dirty) dynamic stochastic general equilibrium model. In particular, we examine the optimal response of the interest rate to changes in sectoral inflation due to standard supply shocks, conditional on a given environmental policy. We then compare the performance of a nonstandard monetary rule with sectoral inflation targets to that of a standard Taylor rule. Our main results are as follows: first, the optimal monetary policy is affected by the existence of environmental policy (carbon taxation), as this introduces a distortion in the relative price level between the clean and dirty sectors. Second, compared with a standard Taylor rule targeting aggregate inflation, a monetary policy rule with asymmetric responses to sector-specific inflation allows for reduced volatility in the inflation gap, output gap, and emissions. Third, a nonstandard monetary policy rule allows for a higher level of welfare, so the two goals of welfare maximization and emission minimization can be aligned.

A Belowground Perspective on the Nexus between Biodiversity Change, Climate Change, and Human Well-being
Michael Koetter, et al.
Journal of Sustainable Agriculture and Environment,
No. 2,
2024
Abstract
Soil is central to the complex interplay among biodiversity, climate, and society. This paper examines the interconnectedness of soil biodiversity, climate change, and societal impacts, emphasizing the urgent need for integrated solutions. Human-induced biodiversity loss and climate change intensify environmental degradation, threatening human well-being. Soils, rich in biodiversity and vital for ecosystem function regulation, are highly vulnerable to these pressures, affecting nutrient cycling, soil fertility, and resilience. Soil also crucially regulates climate, influencing energy, water cycles, and carbon storage. Yet, climate change poses significant challenges to soil health and carbon dynamics, amplifying global warming. Integrated approaches are essential, including sustainable land management, policy interventions, technological innovations, and societal engagement. Practices like agroforestry and organic farming improve soil health and mitigate climate impacts. Effective policies and governance are crucial for promoting sustainable practices and soil conservation. Recent technologies aid in monitoring soil biodiversity and implementing sustainable land management. Societal engagement, through education and collective action, is vital for environmental stewardship. By prioritizing interdisciplinary research and addressing key frontiers, scientists can advance understanding of the soil biodiversity–climate change–society nexus, informing strategies for environmental sustainability and social equity.

Climate Change-Related Regulatory Risks and Bank Lending
Isabella Müller, Eleonora Sfrappini
ECB Working Paper,
No. 2670,
2022
Abstract
We identify the effect of climate change-related regulatory risks on credit real-location. Our evidence suggests that effects depend borrower's region. Following an increase in salience of regulatory risks, banks reallocate credit to US firms that could be negatively impacted by regulatory interventions. Conversely, in Europe, banks lend more to firms that could benefit from environmental regulation. The effect is moderated by banks' own loan portfolio composition. Banks with a portfolio tilted towards firms that could be negatively a affected by environmental policies increasingly support these firms. Overall, our results indicate that financial implications of regulation associated with climate change appear to be the main drivers of banks' behavior.

Green Technologies as Industrial Policy Concept? The South of Saxony-Anhalt as a Case Example
Jörg Döpke, Philip Maschke, C. Altmann, D. Bieräugel
List Forum für Wirtschafts- und Finanzpolitik,
No. 1,
2015
Abstract
Die bundespolitische Maßnahme der Energiewende und das Erneuerbare-Energien-Gesetz (EEG) als Teil davon haben in Sachsen-Anhalt Hoffnungen ausgelöst, die insbesondere mit der Förderung grüner Technologien in Verbindung standen. Das vorliegende Papier stellt eine Analyse der Wirkungen von Subventionen im Allgemeinen dar und widmet sich dem EEG und seiner Auswirkungen im Speziellen. Dazu werden auch Ergebnisse einer Befragung herangezogen, welche die Industrie- und Handelskammer (IHK) Halle-Dessau bei Unternehmen im südlichen Sachsen-Anhalt durchgeführt hat.
