    Economic policy uncertainty and bank stability: Size, capital, and liquidity matter
    (Elsevier Science Inc, 2024) Danisman, Gamze Ozturk; Tarazi, Amine
    We examine the impact of economic policy uncertainty on bank stability post-2007-2008 global financial crisis and how bank size, capital, and liquidity mitigate this relationship. We use 176,477 quarterly observations for US commercial banks over the period from 2011Q1 to 2020Q3 and find consistent and robust evidence that bank stability decreases as the level of economic policy uncertainty increases. We show that bank size, capital, and liquidity matter, i.e., the negative impact of policy uncertainty on bank stability is stronger for larger banks and weaker for highly capitalized banks as well as for more liquid banks. Our channel analysis shows that the increase in the level and volatility of lending and deposit rates, and the decrease in risk-adjusted capitalization and risk-adjusted profitability might to some extent explain the decrease in bank stability in times of higher economic policy uncertainty. Additional analysis reveals that higher market power mitigates the negative impact of EPU on bank stability. Our findings support the Basel II and III regulatory reforms aimed at tightening the capital levels with stricter rules for the larger banks and the implementation of the newly introduced liquidity rules.

    ESG performance and dividend payout: A channel analysis
    (Academic Press Inc Elsevier Science, 2023) Bilyay-Erdogan, Seda; Danisman, Gamze Ozturk; Demir, Ender
    This paper investigates the impact of environmental, social, and governance (ESG) performance on corporate dividend policy. We employ a panel data set comprised of 1094 non-financial listed firms in 21 European countries from 2002 to 2019. We show that companies with higher ESG performance are likely to pay higher dividends. Our results are robust to alternative variable definitions and specifications and address endogeneity concerns. We next investigate the possible transmission channels through which corporate ESG performance enhances dividend payouts. We present novel evidence that earnings and risk are the two possible channels through which ESG performance augments corporate dividends.

    ESG performance and investment efficiency: The impact of information asymmetry
    (Elsevier, 2024) Bilyay-Erdogan, Seda; Danisman, Gamze Ozturk; Demir, Ender
    This paper investigates the relationship between firms' engagement in environmental, social, and governance (ESG) activities and corporate investment efficiency, using 1,094 firms from 21 countries in Europe, covering the years 2002-2019. We conduct our estimations using fixed effects panel data techniques and address potential endogeneity with instrumental variables (IV) estimations. We provide evidence that overall ESG engagement is positively and significantly associated with investment efficiency. Analyzing overinvestment and underinvestment scenarios shows that ESG engagement decreases only overinvestment problems. Within the underinvestment scenario, we observe that ESG engagement is beneficial only for firms with higher information asymmetries. Thus, information asymmetry matters in the underinvestment case. We next show that four firm-level channels-information asymmetry, financial constraints, cash flows, and risk-link ESG performance to investment inefficiency. Additional analysis shows that firms with extreme ESG scores (i.e., very low and very high) do not experience significant reductions in investment inefficiency. Altogether, our findings draw attention to the critical role of ESG performance and information asymmetry in determining corporate investment efficiency.
