    Economic policy uncertainty and green innovation: evidence from China
    (Elsevier, 2022-11-11) Cui, X.; Wang, C.; Şensoy, Ahmet; Liao, J.; Xie, X.
    Frequent economic policy adjustments lead to significant increases in economic policy uncertainty (EPU). Few studies have investigated whether EPU influences corporate green innovation. Using a sample of Chinese A-share listed firms from 2005 to 2019, we find strong evidence that EPU is significantly and negatively associated with corporate green innovation. Our moderating effect analysis shows that financial constraints exacerbate the negative impact of EPU on green innovation, while government environmental subsidies can significantly mitigate the negative EPU effect. Moreover, the negative relationship between EPU and green innovation is salient in privately owned enterprises, firms with less industry competition, and firms in regions with weak intellectual property protection. This study has important implications for policymakers regarding increasing government expenditure on environmental protection and strengthening intellectual property protection to promote corporate green innovation.

    (Elsevier, 2021-02-24) Rehman, M. U.; Şensoy, Ahmet; Eraslan, V.; Shahzad, S. J. H.; Vo, X. V.
    This paper examines the sensitivity of major US sectoral returns to economic policy uncertainty and investor sentiments. Our analysis is based on weekly frequency and ranges from January 1995 to December 2015 covering a span of 20 years. Considering existing, however limited evidence of non-linear structure exhibited by investor sentiments and economic policy uncertainty and on the basis of our non-linear diagnostics, we use novel technique of non-parametric causality in quantiles approach proposed by Balcilar, Gupta, and Pierdzioch (2016). Our results highlight that economic policy uncertainty and investor sentiments act as driving factors for US sectoral returns. The nature of relationship is reported as asymmetrical for stock returns and symmetrical for variance of returns with an exception of Healthcare sector for economic policy uncertainty and bullish market sentiments. Our study carries implications for portfolio diversification and policy makers for forecasting market efficiency and economic trends.
