    Spillover Effects of Sanctions on Airlines
    Corbet, Shaen; Nicolau, Juan Luis; Oxley, Les (Sage, 2023-11-29)
    To counter the escalating threat of direct conflict with rogue nations, the use of sanctions packages has become a preferred tactical response. However, although targeted, there are significantly elevated spillover effects that can generate sectoral damage. While the literature on sanctions has focused on analyzing the effectiveness and the impact on the sanctioned and sanctioning country, spillover effects have not been addressed in the tourism and travel industry. Based on behavioral decision theory and modern portfolio theory, this study states hypotheses and confronts two potential results derived from each theory regarding the way negative consequences of sanctions spill over into airlines. Using the aviation sanctions packages derived from the Russia-Ukraine war in 2022 in different regions worldwide, the results indicate greater spillovers flow into airlines than other aviation-related corporations, into big firms than small firms, and with significant differential effects on each analyzed region.

    Understanding reputational disaster during economic crises: Evaluating aviation sector response differentials
    Akyildirim, Erdinc; Corbet, Shaen; Nicolau, Juan Luis; Oxley, Les (Elsevier, 2025-02-01)
    This research investigates the impact of reputational events on the financial performance of airlines, with a particular focus on differential behaviour regarding the types of events—environmental, social, and governance (ESG), and the economic cycle, whether recessionary or expansionary. Based on a sample of 6288 events, our findings reveal a distinct pattern of depressed returns and increased variance in the aftermath of high severity and novel reputational events—more pronounced during periods of domestic economic crisis. Interestingly, our results show that reputational damage tied to environmental issues does not carry the same weight as those in social and governance categories. Further, contagion effects are identified within the industry, with significant spillovers observed during periods of stability and crisis. This research holds important implications for corporate reputation management, ESG investing, and regulatory policy, underlining the need for transparent communication and stringent oversight across the aviation industry.
