Economic Uncertainty and Climate Change Exposure
(Academic Press Ltd- Elsevier Science Ltd, 2025) Öztürk Danışman, Gamze; Erdoğan, Seda; Demir, Ender; International Trade and Finance
This paper explores how economic uncertainty affects firms' climate change exposure. We use an extensive sample from 24 countries from 2002 to 2021. Employing a novel measure of firm-level climate change exposure developed by Sautner et al. (2023b), we empirically demonstrate that prior to the Paris Agreement in 2015, economic uncertainty leads to a decrease in climate change disclosures. However, after the Paris Agreement, our findings reveal a positive association between economic uncertainty and climate change exposure. The positive disclosure effect is primarily driven by higher climate-related opportunities and regulatory exposures. Our findings are robust when we employ alternative definitions for economic uncertainty, alternative samples, additional firm-level and country-level control variables, and alternative methodologies. We find that institutional and foreign ownership positively moderates the association between economic uncertainty and climate change exposure after the Paris Agreement. Further analysis investigates the moderating impact of country-level environmental performance indicators. We present novel empirical evidence suggesting that firms operating in countries with less climate vulnerability, higher readiness, more stringent environmental policies, superior climate protection performance, and higher environmental litigation risk tend to have higher climate change exposure in uncertain times.

The Impact of Economic Uncertainty and Geopolitical Risks on Bank Credit
(Elsevier Inc., 2021) Demir, Ender; Öztürk Danışman, Gamze; Danışman, Gamze Öztürk; International Trade and Finance
This paper compares the effects of economic uncertainty and geopolitical risks on bank credit growth. Using a sample of 2439 banks from 19 countries for the period of 2010–2019, our findings indicate that economic uncertainty causes a significant decrease in overall bank credit growth while no such significant overall effect of geopolitical risks is documented. Further analysis on loan types shows that the highest negative impact of economic uncertainty is observed on corporate loans. Geopolitical risk, however, dampens consumer and mortgage loans. Additional analyses on bank heterogeneity reveal that the credit behavior of foreign and publicly listed banks are more immune to such risks.

Banking Sector Reactions To Covid-19: the Role of Bank-Specific Factors and Government Policy Responses
(Elsevier, 2021) Demir, Ender; Öztürk Danışman, Gamze; Danisman, Gamze Ozturk; International Trade and Finance
This paper examines the impact of bank-specific factors and variations in the context of stringency of government policy responses on bank stock returns because of the COVID-19 pandemic. A sample of 1,927 publicly listed banks from 110 countries is used for the period of the first major wave of COVID-19, that is, January to May 2020. Our findings indicate that stock returns of banks with higher capitalization and deposits, more diversification, lower non-performing loans, and larger size are more resilient to the pandemic. While banks' environment and governance scores do not have a significant impact, higher social and corporate social responsibility strategy scores intensify the negative stock price reaction to COVID-19. We further observe that the pandemic induced reduction in bank stock prices is mitigated as the strictness of government policy responses increases, mainly through economic responses such as income support, debt and contract relief, and fiscal measures from governments.

How Organizational and Geographic Complexity Influence Performance: Evidence From European Banks
(Elsevier B.V., 2021) Nyola, Annick Pamen; Öztürk Danışman, Gamze; Sauvlat, Alain; Tarazi, Amine; Danışman, Gamze Öztürk; International Trade and Finance
We empirically investigate how bank internationalization, organizational complexity, and geographical complexity stemming from foreign-affiliate type and geographic dispersion affect parent bank stability and profitability. We base our analysis on unique, hand-collected data for the worldwide locations of subsidiaries and branches of EU banks. Our results show that internationalization benefits bank stability by reducing default risk, and it is significantly associated with lower earnings volatility but poorer profitability. With regard to foreign organizational complexity, banks with both foreign subsidiaries and foreign branches are more stable than banks with foreign branches exclusively, which are more stable than banks with only foreign subsidiaries. Nevertheless, higher geographic complexity is associated with lower default risk, higher volatility in earnings, and higher profitability. Further investigations on the sovereign debt crisis and bank size indicate that the sovereign debt crisis in 2011 amplified the relationship and our findings mainly hold for small banks.
Determinants of Bank Lending 'evidence From Brics Countries'
(Kadir Has Üniversitesi, 2023) Ahmed, Abdullai; Öztürk Danışman, Gamze; Öztürk Danışman, Gamze; International Trade and Finance
This thesis aims to investigate the determinants of bank lending for the countries forming BRICS, namely Brazil, Russia, India, China, and South Africa. The empirical analysis is performed using a sample of 130 listed commercial banks between 2000 and 2021. While bank-level data is obtained from Thomson Reuters Refinitiv Eikon, country-level data is extracted from the World Bank. The study uses panel data estimation techniques with fixed effects regression models. Study findings show that bank size, capital adequacy ratio, credit risk, the share of deposits and return on asset have a direct influence on bank lending in BRICS countries since all these variables are statistically significant. Larger banks are observed to lend more, and banks with higher shares of deposit, higher capital adequacy ratios, higher return on assets and higher credit risk are observed to lend more. Country-level variables such as gross domestic product per capita, real interest rate, deposit interest rate, and lending interest rate have no direct impact on bank lending. In contrast, banks in countries with higher inflation lend more. This study points out differences in the determinants of bank lending in the BRICS countries versus the rest of the world and offers important policy implications.

Bank Credit in Uncertain Times: Islamic Vs. Conventional Banks
(Elsevier Ltd, 2020) Bilgin, Mehmet Hüseyin; Öztürk Danışman, Gamze; Danışman, Gamze Öztürk; Demir, Ender; Tarazi, Amine; International Trade and Finance
This paper explores whether the impact of economic uncertainty on credit growth differs for Islamic vs. conventional banks. Using a sample of 416 banks (58 Islamic and 358 conventional) in 12 countries, the findings indicate that an increase in economic uncertainty significantly decreases the credit growth of conventional banks but does not have any significant impact on Islamic banks’ credit growth. Our results are robust to alternative specifications and addressing endogeneity concerns using GMM estimators. We further observe that our findings are stronger for the following countries: (1) countries with explicit deposit insurance protection system for Islamic banks, (2) lower foreign dominance, and (3) countries with a higher share of deposits and assets in Islamic banks.

Economic Uncertainty and Bank Stability: Conventional Vs. Islamic Banking
(Elsevier Science Inc, 2021) Bilgin, Mehmet Huseyin; Öztürk Danışman, Gamze; Danisman, Gamze Ozturk; Demir, Ender; Tarazi, Amine; International Trade and Finance
In this paper, we explore whether economic uncertainty differently affects the default risk of Islamic and conventional banks. Using a sample of 568 banks from 20 countries between 2009 and 2018, we use the World Uncertainty Index (WUI) by Ahir et al. (2018) to conduct a study based on a comparable measure across countries. Our findings indicate that economic uncertainty increases the default risk of conventional banks but does not affect Islamic banks' default risk. To understand why, we explore the influence of religiosity, institutional factors, and bank-level heterogeneity. We observe that Islamic banks' default risk is not significantly affected by uncertainty in all types of countries, but such a difference with conventional banks mainly holds for banks with higher income diversification, larger size, and that are publicly traded. Moreover, our findings show that conventional banks suffer more from uncertainty in terms of stability in countries with higher religiosity and with a higher share of profit-loss sharing (PLS) contracts. Our results are robust to alternative estimation techniques to deal with endogeneity and to alternative variable measurements.
Asimetrik Maliyet Davranışı ve Alıcıların Getirileri: A.b.d. Birleşmelerinden Bulgular
(2019) Ugurlu, Mine; Öztürk Danışman, Gamze; Danışman, Gamze Öztürk; Vural Yavaş, Çiğdem; Bılyay-erdogan, Seda; Vural-yavas, Cigdem; International Trade and Finance
Bu çalışma alıcıların satış, genel ve yönetim maliyetlerinin asimetrik davranışlarını incelemekle birlikte; “Birleşme ve Satın Alma” performanslarına olan etkisini 1 yıllık olay penceresinden analiz etmektedir. Çalışma A.B.D.’de 2003-2015 yılları arasında tamamlanan 6,888 birleşme ve satınalmaya dayanmakta ve panel veri regresyonları kullanmaktadır. Sonuçlar alıcıların 73%’ünün maliyetlerinin asimetrik davranış sergilediğini göstermektedir. Birleşme duyurusunun ardından maliyet yapışkanlığı ile alıcıların olağandışı getirileri arasında anlamlı ve negatif bir ilişki olduğu saptanmıştır. Piyasadaki rekabet alıcıların getirilerini olumlu etkiler, ancak yapışkan maliyetlerin alıcıların olağandışı getirileri üzerindeki olumsuz etkisini daha da artırır. Ayrıca alıcıların temerrüt riskinin olağandışı getiriler üzerinde anlamlı ve negatif yönde etkisi vardır. Bununla birlikte, temerrüt riskinin getiriler üzerindeki olumsuz etkisi yapışkan olmayan maliyet yapısı olan alıcılar için daha kuvvetlidir. Alıcıların riski rekabetin getiriler üzerindeki pozitif etkisini azaltmaktadır. Bir yıllık olay penceresinden incelendiğinde, yapışkan maliyet yapısına sahip alıcıların yapışkan olmayan maliyet yapısına sahip alıcılara göre daha az olağandışı getirilere sahip olduğu gözlemlenmiştir. Bu çalışma 2003-2015 yılları arasında gerçekleşen birleşmelerde rol alan alıcıların asimetrik maliyet davranışlarını ortaya çıkararak ve alıcı firmaların daha düşük olağandışı getiri elde etmelerine alternatif bir açıklama getirerek literatüre katkıda bulunmuştur.

The Effect of Pandemics on Domestic Credit: a Cross-Country Analysis
(Economics Bulletin, 2021) Danisman, Gamze Ozturk; Öztürk Danışman, Gamze; Demir, Ender; International Trade and Finance
Using a panel of 140 countries covering the period 1996-2018, this paper examines how previous pandemics (such as SARS, MERS, Ebola, Swine flu, etc.) have influenced the lending behavior of banks. We take advantage of a new index developed by Ahir et al. (2020) which measures discussions about pandemics at the country level. Our findings reveal that uncertainty related to pandemics significantly hamper domestic credit available to the private sector. The negative effect of pandemics on credit levels is more prevalent for the low-income & emerging economies and non-OECD countries.

Asymmetric Cost Behavior and Acquirer Returns: Evidence From U.s. Mergers
(Ege Univ, 2019) Uğurlu, Mine; Öztürk Danışman, Gamze; Öztürk Danışman, Gamze; Vural Yavaş, Çiğdem; Bilyay-Erdoğan, Seda; Vural-Yavaş, Çiğdem; International Trade and Finance
This paper investigates the asymmetric behavior of the selling, general and administrative (SG&A) costs of acquirers, and reveals its effects on mergers & acquisitions (M&A) performance in a one-year event window. It is based on a sample of 6888 M&As completed in the U.S. during the 2003-2015 period and employs panel data regressions. The results show that 73% of the acquirers display asymmetric cost behavior. A significant negative relation is found between cost stickiness and acquirers' abnormal returns following the merger announcement. Competition in the market for corporate control is positively related with acquirer returns but exacerbates the negative effects of cost-stickiness on abnormal returns of acquirers. The acquirers' risk of default is significantly negatively related to the abnormal returns they generate. This adverse effect of default risk on returns is stronger for acquirers with anti-sticky costs. Acquirer risk offsets the positive effects of competition on returns. Acquirers with sticky costs have lower abnormal returns than those with anti-sticky costs in a one-year window. The present study contributes to the literature by revealing the asymmetric cost behavior of acquirers involved in merger activity during the last decade, and provides evidence for an alternative explanation for the lower abnormal returns of the acquiring firms.
