  • Behavioural finance and cryptocurrencies

    Ballis, Antonis; Verousis, Thanos (Review of Behavioral Finance, 2022)
    The present study sets out to examine the empirical literature on the behavioural aspects of cryptocurrencies, showing the findings of related studies and discussing the various results. A systematic literature review of cryptocurrencies in behavioural finance seems to be timely and particularly important in terms of providing a guide for future research. Key topics include an extent review on the issue of herding behaviour amongst cryptocurrencies, momentum effects and overreaction, contagion effect, sentiment and uncertainty, along with studies related to investment decision-making, optimism bias, disposition, lottery and size effects.
  • Information and the arrival rate of option trading volume

    Zhang, Mengyu; Verousis, Thanos; Kalaitzoglou, Iordanis (The Journal of Futures Markets, 2022)
    In this paper we investigate the interaction between liquidity and information in the options market and its impact on the pricing of the underlying asset. We model option trade duration and volume jointly, for the first time, as a natural measure of options' trading intensity and we associate it with differential degrees of information present in option trades. We report a highly significant association between option trading intensity with contemporaneous and future underlying volatility and returns, which is robust to the presence of other information measures, market factors, and structural forms.
  • LGBTQ and finance

    Brahma, Sanjukta; Gavriilidis, Konstantinos; Kallinterakis, Vasileios; Verousis, Thanos (International Review of Financial Analysis, 2023)
    Recent changes in workplace and corporate board diversity policies and a series of court rulings have signalled a fundamental change in the treatment of lesbian, gay, bisexual, transgender and queer (henceforth LGBTQ) people in the corporate world. In this paper, we survey the burgeoning literature on the role of sexual orientation in finance. Studies show that there is a positive relationship between the adoption of LGBTQ-friendly policies and firm performance. We identify the factors that influence a firm's decision to adopt LGBTQ-friendly policies. We also provide evidence that sexual preferences play an important role in leadership styles in the household. Overall, our review suggests that LGBTQ research allows novel insights regarding how LGBTQ policies create value for the firm, insights that help us identify several directions for future research.
  • Financial stress and commodity price volatility

    Chen, Louisa; Verousis, Thanos; Wang, Kai; Zhou, Zhiping (Energy Economics, 2023)
    We use a Markov-switching vector autoregressive model to examine the impact of financial stress on the volatility of commodity prices, including energy volatility. An increase in financial stress leads to a persistent increase in the volatility of the commodity index and of individual commodity prices. We confirm the existence of three volatility regimes, with the volatility of the commodity index and of individual commodity prices in the high volatility regime being more than 25 times larger than that in other regimes. A financial stress shock that arrives during a highly volatile period has more destabilizing and persistent effects than when the shock arrives during a low volatility period. The impact on energy volatility in the high volatility regime is over 60% larger than that on the volatility of the commodity index. The high volatility regime is short-lived and reflects major economic events as well as the outbreak of the COVID-19 pandemic.
  • Vice-chancellor narcissism and university performance

    Khoo, Shee-Yee; Perotti, Pietro; Verousis, Thanos; Watermeyer, Richard (Research Policy, 2024)
    Universities hold a prominent role in knowledge creation through research and education. In this study, we examine the effects of VC narcissism on university performance. We measure VC narcissism based on the size of the signature, in line with a methodological approach which has been widely used in the recent literature and repeatedly validated in laboratory experiments. We exploit a quasi-natural experiment of VC changes and employ a Difference-in-Difference research design, which alleviates concerns related to endogeneity and identification bias. We show that the appointment of a highly narcissistic VC leads to an overall deterioration in research and teaching performance and concomitantly league table performance. We further identify excessive financial risk taking and empire-building as possible mechanisms explaining the main results and provide evidence on the moderating role of university governance. Our findings are consistent with the view that narcissism is one of the most prominent traits of destructive leadership; they also have practical implications for leadership recruitment and the monitoring of leadership practices in the higher education sector. The results of this study extend prior research in several ways. Extant literature on executive leadership and narcissism yields inconclusive findings; this literature has mainly focused on for-profit organisations and has not considered universities. In addition, prior research in higher education on the determinants of university performance has not yet examined the role of leadership personality traits.
