Loan Securitisation during the Transition to a Low-carbon Economy
Isabella Müller, Huyen Nguyen, Trang Nguyen
VoxEU CEPR,
May
2023
Abstract
Banks play a crucial role in the transition to a low-carbon economy, but they also expose themselves to climate transition risk. This column shows that banks use corporate loan securitisation to shift climate transition risk to less-regulated shadow banking entities. This behaviour affects carbon premia in loan contracts. When banks can use securitisation to manage transition risk, their climate policies that target only activities reflected in their books may not be as effective as bank regulators hope for.

Sources of Large Firms’ Market Power and Why It Matters
Filippo di Mauro, Matthias Mertens, Bernardo Mottironi
VOXEU COLUMN,
January
2023
Abstract
Excessive market power has detrimental effects on the functioning of the economy, raising consumer prices, distorting the allocation of resources, and creating welfare losses. The existing literature has largely focussed on competition in product markets. This column argues that it is important to differentiate between various sources of firm market power on output and input (most notably labour) markets. European firm-level data reveals that large firms charge lower markups in product markets but exert their market power significantly in labour markets. Competition authorities can and must distinguish between the sources of market power when attempting to regulate it.

Business Cycle Characteristics of Mediterranean Economies: a Secular Trend and Cycle Dynamics Perspective
Anna Solms, Bernd Süssmuth
International Economics and Economic Policy,
October
2022
Abstract
This study analyzes business cycle characteristics for all 20 major contemporaneous economies bordering the Mediterranean Sea based on annual real gross domestic product series for the period from 1960 to 2019. The region we investigate corresponds to the Mare Internum region of the Imperial Roman Empire during the Nerva-Antonine and early Severan dynasty, i.e., at the time of the maximum extent of the Roman Empire around 100 to 200 CE. The covered area encircles the Mediterranean, including economies now belonging to the European Union as well as acceding countries, Turkey, and the Middle East and North African economies. Using a components-deviation-cycle approach, we assess level trends and relative volatility of output. We also quantify the contribution of various factors to the business cycle variability within a region. We find cyclic commonalities and idiosyncrasies are related to ancient and colonial history and to contemporaneous trade relationships. Caliphate and Ottoman Empire membership as well as colonial rule in the twentieth century and contemporary Muslim share of population are the most promising predictors of business cycle commonalities in the region.

War drives up energy prices ‒ High inflation weighs on economy
While the lifting of nationwide coronavirus regulations boosts many service sectors such as the hospitality industry, supply bottlenecks are likely to weigh on the manufacturing sector throughout the summer and high inflation will dampen private consumption. Gross domestic product (GDP) in Germany is expected to decline slightly in the second quarter of 2022. The situation in the manufacturing sector is expected to ease towards the end of the year. The Halle Institute for Economic Research (IWH) forecasts that GDP will increase by 1.5% in 2022, following an increase by 2.9% in 2021. In East Germany, GDP will increase by 1%.

Capital Requirements, Market Structure, and Heterogeneous Banks
Carola Müller
IWH Discussion Papers,
No. 15,
2022
Abstract
Bank regulators interfere with the efficient allocation of resources for the sake of financial stability. Based on this trade-off, I compare how different capital requirements affect default probabilities and the allocation of market shares across heterogeneous banks. In the model, banks‘ productivity determines their optimal strategy in oligopolistic markets. Higher productivity gives banks higher profit margins that lower their default risk. Hence, capital requirements indirectly aiming at high-productivity banks are less effective. They also bear a distortionary cost: Because incumbents increase interest rates, new entrants with low productivity are attracted and thus average productivity in the banking market decreases.

Aspects of the Political Economy of the European Banking Union
Lena Tonzer
PolEconFin Initiative,
2021
Abstract
The regulatory architecture of the financial system has significantly changed after the global financial crisis of 2008/09. In Europe, the introduction of the Single Rulebook has been a major change and provides the legal foundation for the European Banking Union (EBU). The Single Rulebook consists of a regulation, the Capital Requirements Regulation (CRR), and three main directives targeting capital regulation and compensation of managers, harmonization of deposit insurance schemes, as well as resolution and restructuring rules (Capital Requirements Directive (CRD IV), Deposit Guarantee Schemes Directive (DGSD), Bank Recovery and Resolution Directive (BRRD)).
