Regulation of International Financial Markets and International Banking

This research group analyses causes and consequences of banks' international activities and the regulatory framework they operate in.

Internationally active banks can facilitate an efficient international allocation of capital and provide channels for international risk sharing. But they can also be a source of financial instabilities themselves, thus contributing to international contagion and risk-shifting. This is one reason for the current re-regulation of international banking.

The research group contributes to the literature in three ways. First, the group empirically analyses the channels through which shocks are transmitted by internationally active banks. Second, the group analyses the build-up of aggregate imbalances in integrated banking markets and resulting consequences for the real economy. Third, the group analyses the impact of changes in banking supervision and regulation on (inter)national activities of banks, with a special focus on the European integration process.

Delay Determinants of European Banking Union Implementation

Michael Koetter Thomas Krause Lena Tonzer

in: European Journal of Political Economy, 2019

Abstract

Most countries in the European Union (EU) delay the transposition of European Commission (EC) directives, which aim at reforming banking supervision, resolution, and deposit insurance. We compile a systematic overview of these delays to investigate if they result from strategic considerations of governments conditional on the state of their financial, regulatory, and political systems. Transposition delays pertaining to the three Banking Union directives differ considerably across the 28 EU members. Bivariate regression analyses suggest that existing national bank regulation and supervision drive delays the most. Political factors are less relevant. These results are qualitatively insensitive to alternative estimation methods and lag structures. Multivariate analyses highlight that well-stocked deposit insurance schemes speed-up the implementation of capital requirements, banking systems with many banks are slower in implementing new bank rescue and resolution rules, and countries with a more intensive sovereign-bank nexus delay the harmonization of EU deposit insurance more.

National Culture and Risk-taking: Evidence from the Insurance Industry

Chrysovalantis Gaganis Iftekhar Hasan Panagiota Papadimitri Menelaos Tasiou

in: Journal of Business Research, April 2019

Abstract

The gravity of insurance within the financial sector is constantly increasing. Reasonably, after the events of the recent financial turmoil, the domain of research that examines the factors driving the risk-taking of this industry has been signified. The purpose of the present study is to investigate the interplay between national culture and risk of insurance firms. We quantify the cultural overtones, measuring national culture considering the dimensions outlined by the Hofstede model and risk-taking using the ‘Z-score’. In a sample consisting of 801 life and non-life insurance firms operating across 42 countries over the period 2007–2016, we find a strong and significant relationship among insurance firms' risk-taking and cultural characteristics, such as individualism, uncertainty avoidance and power distance. Results remain robust to a variety of firm and country-specific controls, alternative measures of risk, sample specifications and tests designed to alleviate endogeneity.

Elevated Uncertainty during the Financial Crisis: Do Effects on Subjective Well-being Differ across European Countries?

Lena Tonzer

in: B.E. Journal of Economic Analysis and Policy, No. 2, 2019

Abstract

This paper focuses on the effect of uncertainty as reflected by financial market variables on subjective well-being. The analysis is based on Eurobarometer surveys, covering 18 countries over the period 2000–2013. Individuals report lower levels of life satisfaction in times of higher uncertainty approximated by stock market volatility. This effect is heterogeneous across respondents: the probability of being unsatisfied is higher for respondents who are older, unemployed, less educated, and live in one of the GIIPS countries of the Euro area. Furthermore, higher uncertainty in combination with a financial crisis increases the probability of reporting low values of life satisfaction.

Drivers of Systemic Risk: Do National and European Perspectives Differ?

Claudia M. Buch Thomas Krause Lena Tonzer

in: Journal of International Money and Finance, March 2019

Abstract

With the establishment of the Banking Union, the European Central Bank has been granted the power to impose stricter regulations than the national regulator if systemic risks are not adequately addressed at the national level. We ask whether there is a cross-border externality in the sense that a bank’s systemic risk differs when applying a national versus a European perspective. On average, banks’ contribution to systemic risk is similar at the two regional levels, and so is the ranking of banks. Generally, larger banks and banks with a lower share of loans are more systemically important. The effects of these variables are qualitatively but not quantitatively similar at the national versus the European level.

Political Influence and Financial Flexibility: Evidence from China

Xian Gu Iftekhar Hasan Yun Zhu

in: Journal of Banking and Finance, February 2019

Abstract

This paper investigates how political influence affects firms’ financial flexibility and speed of adjustment toward target leverage ratios. We find that at the macro level, firms in environments with high political advantages, proxied by provincial affiliations with heads of state as well as political status and party rank of provincial leaders, adjust faster. At the micro level, firms that are state-owned, have CPC members as executives, or bear low exposure to changes in political uncertainty adjust faster. When interacted, the micro-level political factors have more significant impact.

Explaining Regional Disparities in Housing Prices across German Districts

Lars Brausewetter Stephan L. Thomsen Johannes Trunzer

in: IZA Institute of Labor Economics, March 2022

Abstract

Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
