- Abstract On 23 June 2016, a referendum was held in the United Kingdom (UK) to decide whether the country should leave or remain a member of the European Union (EU). The ‘Leave’ vote won by 52 per cent to 48 per cent of voters, leading to the EU–UK Withdrawal Agreement that came into force in 2020 and the Trade and Cooperation Agreement that came into force in 2021. Brexit is not exclusively a European matter; it affects third parties as well. In this article we examine the presence of Japanese affiliates in Europe during 2000–21 by analysing data obtained from the Toyo Keizai's Overseas Japanese Companies database. While the UK has been a major beneficiary of Japanese investments in Europe, its share of Japanese affiliates in Europe has decreased, especially during 2000–10. Brexit has had no negative impact on direct employment created by Japanese affiliates in the UK in the short term, but its impact in the long term could be exacerbated by any further policy divergence between the UK and the EU.Wiley, Oct. 2023, Economic Affairs, 43(3) (3), 314 - 339, English[Refereed]Scientific journal

- Research background: The contribution of banks? non-interest income to the total income becomes particularly important in the face of a severe financial crisis, usually accompanied by burdensome restrictions in economic activity, insolvencies of enterprises and households and low interest rates of central banks.Purpose of the article: This study investigates banks in 40 European countries to determine whether non-interest income had a significant impact on the bank?s profitability and whether the severity of the COVID-19 pandemic influences the form of this relationship.Methods: This study used a linear cross-section model using bank-level data. In the model, the bank?s profitability was regressed with the measure of income diversification, controlling for the pandemic?s intensity and the state of the country?s economy and bank characteristics. Banking data were obtained from the S&P Global MI. The Oxford COVID-19 Government Response Tracker (Hale et al., 2021, pp. 529?538) was the source of pandemic-related variables.Findings & value added: The obtained results indicate that the increases in non-interest income share in the bank?s total income have a statistically significant positive impact on profitability for the European banking sector. The dependence of profitability on diversification was stronger with the growing adverse effects of the pandemic. Our results are in line with those for the US banks (Li et al., 2021) and the European Central Bank Banking Supervision?s assessment that higher non-interest income has allowed banks? profitability in the euro area to be maintained at a pre-pandemic level (ECB, 2021). In addition, the study contributes to previous literature by testing the impact of the severity of the COVID-19 pandemic on the relationship between income diversification and bank profitability in 40 European countries.Instytut Badan Gospodarczych / Institute of Economic Research, Mar. 2022, Equilibrium, 17(1) (1), 11 - 29, English[Refereed]Scientific journal

- Abstract The importance of the question about the relationship between concentration and efficiency lies in the fact that banks’ efficiency affects ability to extend loans and ensure financial stability of the banking sector. The study examines this relationship on the example of 150 banks operating between 2005 and 2019 in 11 EU and 8 non-EU countries from the SECE region. The value of profit efficiency was assessed with the stochastic frontier approach, and next regressed with the banking market concentration and bank specific and macroeconomic explanatory variables. The results for the entire sample as well as for domestic and foreign-owned banks indicate that concentration positively and nonlinearly impacts bank efficiency, both in EU and non-EU countries. Moreover, the size of a bank and income diversification help to improve efficiency of banks in the SECE region. The study shows that banks in SECE countries seem to follow the efficient structure hypothesis.Walter de Gruyter GmbH, Jun. 2021, South East European Journal of Economics and Business, 16(1) (1), 38 - 52, English[Refereed]Scientific journal

- This article studies the determinants of size differentials between fiscal multipliers in countries around the world, both advanced and developing economies. We introduce variables not considered before for explaining multiplier size differentials, such as capital flows and the openness of capital markets, while controlling for domestic conditions and exchange rate regimes. We also disaggregate GDP into its main components in order to identify the channels through which external and internal factors can influence GDP after a change in fiscal policy. Our results point to the existence of a new channel through which fiscal policy effectiveness is affected. Capital flows, especially FDI flows, play an important role in determining the sizes of fiscal multipliers, and a country’s external conditions largely explain GDP changes after fiscal expenditure shocks. Our results also point towards a strong link between a country’s international position and its real economy.Routledge, Jul. 2018, Applied Economics, 50(32) (32), 3493 - 3514, English[Refereed]Scientific journal
