Daily and Intraday Herding within Different Types of Investors in Borsa Istanbul
(Routledge Journals, Taylor & Francis Ltd, 2019) Ersan, Oğuz; Ekinci, Cumhur; Ersan, Oğuz
This paper aims to explore the daily and intraday herd behavior of various investor groups trading in an emerging equity market, Borsa Istanbul (BIST). We analyze a one-year tick-by-tick order and trade data of BIST 100 Index stocks and document differences in herding behavior of investor groups considering market capitalization, market conditions, and announcements as well as daily and intraday periodicities. We find that nonprofessional investors (brokerage houses and domestic funds) tend to herd on large (small) stocks; their herding behavior mostly exhibits a U shape (an inverse U shape) during the day. All types of investors tend to herd in down markets on a daily basis while this behavior disappears, even inverts intraday.

Economic Policy Uncertainty And Bank Credit Growth: Evidence From European Banks
(Elsevier B.V., 2020) Ersan, Oğuz; Ersan, Oğuz; Demir, Ender
Using a sample of 2977 private and listed banks in the EU-5 countries (the United Kingdom, Germany, Spain, Italy, France) for the years 2009–2018, this paper explores the impact of Economic Policy Uncertainty (EPU) on credit growth. Using panel data fixed effects methodology and controlling for endogeneity using two-step difference GMM estimators, our findings indicate that uncertainty in economic policies hampers the credit growth of European banks. Our bank type-based analyses indicate that the effect is mainly valid for cooperative banks. Additional analyses imply that the negative impact of EPU on credit growth is more pronounced in civil law countries, increases with debt maturity, and weakens for banks with a larger number of employees and branches. Furthermore, the unfavorable effects are stronger in well-capitalized banks, banks with foreign subsidiaries, and banks with a higher share of wholesale funding. We also provide several policy implications for different economic actors.

The effect of European and global uncertainty on stock returns of travel and leisure companies
(Sage Publications Ltd, 2019) Ersan, Oğuz; Akron, Sagi; Demir, Ender
This article aims to evaluate the impact of economic policy uncertainty (EPU) on the STOXX Europe 600 Travel & Leisure Price Index by utilizing a monthly data set for 20 years through 1997-2016. It is found that both the European and the global EPU have significant negative effects on the stock returns of travel and leisure companies. We demonstrate the significantly superior forecasting power of EPU measures on tourism and leisure stock returns relative to a rather weak forecasting power of various macroeconomic variables.

Financial inclusion and bank stability: evidence from Europe
(Routledge Journals, 2020) Danışman, Gamze Öztürk; Tarazi, Amine
The Great Recession of 2007-2009 piqued the interest of policymakers worldwide, prompting various initiatives to stabilize the financial system and advance financial inclusion. However, few studies have considered their interconnectedness or whether any synergies or trade-offs exist between them. This paper investigates how financial inclusion affects the stability of the European banking system. The findings indicate that advancements in financial inclusion through more account ownership and digital payments have a stabilizing effect on the banking industry. A deeper investigation shows that such a stabilizing impact is mainly driven by the targeting of disadvantaged adults who are young, undereducated, unemployed, and who live in rural areas. Hence, along with its known benefits to society as a whole, financial inclusion has the additional benefit of improving the stability of the financial system. Such findings call for policy configurations that are specifically designed to achieve financial inclusion for disadvantaged individuals.

The impact of short selling on intraday volatility: evidence from the Istanbul stock exchange
(IEEE, 2012) Çankaya, Serkan; Eken, Mehmet Hasan; Ulusoy, Veysel
This paper examines the interrelation between short selling and volatility as differing from previous research in that it focuses on intraday activities rather than the daily price movements. We demonstrate that the effects of short selling activity changes during the two sessions of the day and rest of trading hours. The study also presents evidence that there is a considerable amount of short selling activity in the Istanbul Stock Exchange (ISE) particularly at the beginning of opening sessions which significantly impacts the volatility of the market for the rest of the trading day. © EuroJournals Publishing Inc. 2012.

Loan loss provisioning of US banks: Economic policy uncertainty and discretionary behavior
(Elsevier Inc, 2021) Öztürk Danışman, Gamze; Demir, Ender; Ozili, Peterson K.
This paper examines the effect of economic policy uncertainty (EPU) on loan loss provisions (LLP). Using a sample of 6384 US banks and yearly data from 2009 to 2019 and addressing endogeneity (GMM and IV estimations), the findings reveal that in times of higher economic policy uncertainty, banks tend to increase their loan loss provisioning. Considering the four components of EPU, the findings document that the majority of the explanatory power on loan loss provisions originates from news-based and tax expiration indices. Moreover, US banks discretionally use loan loss provisions in normal times, especially for capital management and income smoothing. In uncertain times, they use provisions for income smoothing rather than capital management and after controlling for the discretionary behavior, the positive relationship of EPU and LLPs continue to hold. Additional analysis indicates that private banks conduct more income smoothing through provisions in uncertain times as compared to listed banks. The findings of the study highlight EPU as an additional procyclical factor to influence bank provisioning behavior and offer some relevant policy implications.
