    The impact of climate policy on U.S. environmentally friendly firms: A firm-level examination of stock return, volatility, volume, and connectedness
    (Elsevier B V, 2023-03) Pham L; Hao W; Truong H; Trinh HH
    This paper investigates the green stock market reaction to climate policy events associated with the Paris Agreement and the U.S. presidential elections. We document abnormal returns, volatility and volume reactions to climate policy events among green stocks. However, the magnitude of the reactions varies between the tightening and loosening of climate policy and across subgroups of the green stock markets. Our connectedness analysis further investigates the spillover patterns among individual green stocks and confirms their heterogeneous natures when responding to the occurrence of these climate policy events. By constructing a minimum connectedness portfolio based on the estimated connectedness among these green stocks, we find that investors can substantially reduce their risks. Our findings have strong implications for policy makers in designing policies to effectively promote green investments and mitigate climate change.

    Dynamic connectedness between crude oil and equity markets: What about the effects of firm's solvency and profitability positions?
    (Elsevier B V, 2023-09) Balli F; O Balli H; Nguyen TTH
    The paper aims to explore the presence of connectedness between oil price changes and stock returns of oil & gas sector. The analysis, adopting the connectedness approach developed by and the frequency connectedness developed by demonstrates a high level of connectedness, especially during the extreme economic meltdown. The short-term (1–5 days) level of total connectedness is substantially higher than the medium-term (5–30 days) and long-term levels (30–262 days). In addition, when examining the impact of the sectors' financial characteristics on the extent of the connectedness, we found that sectors with greater solvency position (lower debt to asset ratio and higher interest coverage) are less connected with the oil price changes. The impact of sector's solvency position on connectedness (between stock return and oil prices) is even more obvious for financially more open markets. Also, change in oil prices have a less impact on the returns of sectors with higher profitability ratios. The paper, therefore, brings several implications to both policy makers and investors.

    Interconnectivity and investment strategies among commodity prices, cryptocurrencies, and G-20 capital markets: A comparative analysis during COVID-19 and Russian-Ukraine war
    (Elsevier Inc, 2023-11) Kumar S; Jain R; Narain; Balli F; Billah M
    Economic and political disorders have multidimensional impacts on all economies around the world. The global world has faced out COVID-19 pandemic in 2020, and now the Russian-Ukraine geopolitical crisis. This study investigates the nexus among commodities, crypto, and G20 capital markets along with risk and returns implications. To examine the impact, we applied the TVP-VAR technique suggested by Koop and Korobilis (2014), and Antonakakis, Chatziantoniou, and Gabauer (2020) by adjusting the framework of Diebold and Yilmaz (2012). The research findings reveal that a high level of connectedness was observed during Covid-19, which was persistent for a long period and has multidimensional impacts. More particularly, EU, Canada, France Germany, and the UK were the principal supplier of spillovers to other commodities, Bitcoin, and the remaining markets. During Geopolitical Crisis (here after GPC), conclusively it is observed that of USA, Brazil, Saudi Arabia, Canada, Mexico, China, Indonesia, and Japan are the net receivers of the volatility spillovers and Russia, Germany, France, European Union, Italy, UK, Argentina, India, Australia, Turkey, Korea, and South Africa are the net transmitters of volatility spillovers. Interestingly, among net transmitters Argentina, South Africa and Turkey are suffered from high inflation and substantial budget deficits, considered as weak economies of G20. Portfolio weights has been increased dramatically during COVID-19 and Russian-Ukraine war. This research could be utilized to take investment, hedging, and diversification decisions about commodities, cryptocurrencies, and stocks, particularly in such turmoil situations with the help of connectedness and various hedging techniques.

    Building connections in health and wellbeing education: Qualitative findings of a study with New Zealand agricultural students
    (SAGE Publications, 2024-01-19) Hay A; Stanley-Clarke N; Maris R; Winder L; Knook J
    Background: As the burden of mental health challenges increases globally, delivering mental health education programmes to at-risk groups is critical. Important factors governing the success of health and wellbeing education include the relationships and connections formed between students and those delivering the education. This article reports on the qualitative findings from a mixed-methods study evaluating a mental health wellbeing programme delivered to first-year agricultural students across two universities in New Zealand. Design: The qualitative data that formed the basis of this article involved an exploratory approach utilising semi-structured interviews with participants who had attended a mental health wellbeing programme. Findings: The study found that feelings of connectedness in relation to the programme and the educators, as well as the material provided, improved engagement. In particular, connection was improved through the use of peer educators from within the target community, alongside considerations of timing, promotion and incentives in the delivery of programmes. Conclusions: Relationships and building connections are crucial when delivering health and wellbeing education. These findings have implications for those developing and delivering educational mental health interventions at tertiary institutions in terms of the mechanisms used to support engagement, learning and integration of knowledge.
