Do competition and market structure affect sensitivity of bank profitability to the business cycle?

Published in Pacific-Basin Finance Journal, 2023

This study aims to determine whether competition and market structure explain heterogeneity in the cyclicality of bank profitability. To answer this question, we consider a large panel of individual bank-level data covering over 8000 banks in more than 100 countries.

Does bank competition matter for the effects of macroprudential policy on the procyclicality of lending?

Published in Journal of International Financial Markets, Institutions and Money, 2022

Despite the extensive debate on the impact of bank competition on risk-taking and procyclicality, there is no evidence of its role in the effects of macroprudential policy on loan growth and on the sensitivity of lending to the business cycle. Using over 80,000 bank-level observations in 95 countries from 2004 to 2015, we find that increased competition strengthens the countercyclical effects of macroprudential policy instruments (MPIs) in terms of reduced loan growth.

Bank-type specific determinants of sensitivity of loan-loss provisions to business cycle

Published in The European Journal of Finance, 2018

In this paper, we explore several new factors which may affect the procyclicality of loan-loss provisions in all commercial and cooperative banks operating in Poland between 2000 and 2012. More specifically, we test whether there are visible differences between commercial and cooperative banks in the sensitivity of those provisions to the business cycle. Our results show that whereas loan-loss provisions are procyclical in both cases, the procyclicality is particularly prominent and stronger in the case of commercial banks, than of the cooperative banks.

What Drives Heterogeneity of Cyclicality of Loan-Loss Provisions in the EU?

Published in Journal of Financial Services Research, 2017

As banks differ in their risk-management approaches, their sensitivity to the business cycle is far from uniform. This paper aims to identify the sources of such diverse relationships between loan-loss provisions (LLP) and the business cycle.
