Through a three-stage research framework combining higher-order moment (third- and fourth-order moments), time-frequency spillover model, and the random forest technique, we identify the influence of global energy countries' geopolitical risks on China's energy futures spillovers under different time horizons. Our third-order moment (skewness) spillover results indicate that crude oil and fuel oil futures primarily play the role of net transmitters in the short-term time scale, while coking coal and bitumen futures are mainly net recipients. In the medium- and long- term time scales, however, thermal coal and fuel oil are stable net recipients. For the fourth-order moment (kurtosis) spillovers, the crude oil consistently acts as the transmitters across all time horizons, with a relatively significant net spillover value. Moreover, Russia's geopolitical risk has the most prominent impact on spillovers in China's energy futures market, followed by Saudi Arabia. Additionally, Russia and Saudi Arabia are more likely to impact upside and downside market spillovers, respectively. These results provide some implications for different types of investors and policy makers.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"140 ","pages":"Article 107981"},"PeriodicalIF":13.6,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142573145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do that, we propose a decision model that co-optimizes the risk-adjusted strategy of a hybrid power plant owner comprising (i) the forward-market involvement, (ii) the contracted amount of network access, and (iii) the share of renewable sources composing the hybrid power plant. We also propose adjusting the current regulatory framework to consider a unified calculation for the Firm Energy Certificates of non-controllable renewable power plants, including hybrid units. Based on that, we ensure a non-discriminatory regulatory framework for renewables acknowledging the diversity of generation profiles that hybrid units may have due to their optimal hybridization shares and network-access contracting strategies.

First, AI has had a significant positive impact on facilitating the ET. This conclusion still holds after a series of robustness tests. Second, AI positively affects ET by promoting renewable energy technology innovation and upgrading the electricity structure, resulting in both technological and structural effects. Third, the impact of AI on ET is non-linear. Threshold effect models show that AI impacts ET differently at various levels of regulation quality (RQ), exhibiting a double threshold effect. AI hinders ET when RQ is lower than the first threshold value. When RQ is in the second range, AI significantly facilitates ET. However, when RQ exceeds the second threshold value, AI hinders ET again. These findings provide insights into the mechanisms of AI's impact on ET and emphasize that an appropriate level of regulation is crucial for AI to facilitate ET.

The findings indicate an inverted U-shaped effect of informality on gasoline efficiency and a level-negative effect of regulation on informality. These results suggest a differential strategy for enhancing gasoline efficiency. Government regulation is more effective in economies at the pre-saturation stage (characterized by normal growth levels of informality) but proves ineffective in economies at the post-saturation stage (characterized by abnormal growth levels of informality), where energy-saving behaviors may be self-motivated. This is corroborated by the inefficiency equation, where indicators of good governance, such as the rule of law, control of corruption, and regulatory quality, are statistically significant in advancing energy efficiency goals. Gasoline efficiency performance varies across countries, with the higher performers also being the continent's most economically advanced.

The empirical investigation is based on a structural vector autoregression model covering the monthly sample period between 1996 m1-2022m10, where global real economic activity is controlled for. The results show that a unit shock to global geopolitical risk (normalized to one standard deviation) results in about 1.13 units of an increase in global energy uncertainty (normalized to one standard deviation) in the long run (after two years), whereas the corresponding effects on global energy prices are statistically insignificant. In contrast, a unit shock to global energy uncertainty results in about 52 % (57 %) of a reduction in global energy prices (global economic activity), acting like negative global demand shocks. When statistically significant country-specific results are considered in the long run, a positive shock to the global geopolitical risk affects domestic energy prices positively (negatively) in 10 % (10 %) of oil producing countries, 32.1 % (19.7 %) of non-oil producing countries, 47.2 % (0 %) of advanced economies, 55 % (0 %) of euro area countries, 25 % (22.4 %) of emerging markets, and 22.2 % (26.7 %) of developing countries.

Further dynamic analyses indicate that higher-order moment connectedness is also time varying and appears to be stronger during uncertain market conditions. In addition, we identify day-of-the-week patterns of higher-order moment connectedness during high uncertainty periods, but these patterns appear to be reversed during low uncertainty periods. The employment of Markov switching regression models further corroborates the market uncertainties as the determinants of higher-order moment connectedness. As an important extension, we provide empirical evidence that including clean energy stocks in the investment portfolio can effectively hedge oil price risks and considering higher-order moments in constructing investment strategies adds extra value to investors. Our utility-based hedging strategy and minimum connectedness portfolio can offer higher utility gains and better risk-return trade-offs to those investors who are not infinitely risk-averse.</div></div>","PeriodicalId":11665,"journal":{"name":"Energy Economics","volume":"140 ","pages":"Article 107987"},"PeriodicalIF":13.6,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142552630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
