In this study, we investigate the complex dynamics between clean energy stock markets and five key US risk factors: climate policy uncertainty, economic policy uncertainty, financial stress, geopolitical risk, and oil price volatility. Our analysis uses the novel quantile-on-quantile connectedness approach, which enables a deeper exploration of the interdependencies between variables not only within the same quantiles but also across various quantiles of their respective distributions. We find substantial inverse connectedness, particularly under extreme market circumstances, underscoring the vulnerability of clean energy stocks to changes in policy uncertainty, financial stress, and oil prices. Geopolitical risk, meanwhile, exhibits a strong direct relationship with clean energy markets, especially in times of heightened geopolitical tension. Additionally, the pairwise connectedness structure tends to intensify throughout paramount political, economic, and climate events or crises. Our findings have practical implications for both investors and policymakers.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"105 ","pages":"Article 105595"},"PeriodicalIF":10.2,"publicationDate":"2025-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877511","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}

The research aims to identify optimal management policies for shared resources by modeling the strategic interactions between these countries. The analysis incorporates key factors such as recovery rates, and information asymmetry, providing a realistic framework for decision-making. The study reveals that full cooperation between Iran and Qatar yields the highest long-term payoffs, emphasizing the benefits of strategic alignment. However, the game-theoretic model also indicates an equilibrium where Iran cooperates, and Qatar does not, resulting in higher payoffs for Qatar. This highlights the challenges in achieving mutual cooperation and underscores the need for robust legal frameworks and negotiation strategies. Using real data from the North Pars field, the mathematical model optimizes extraction values and payoffs, demonstrating the potential of technological advancements and strategic planning. The optimized extraction rates are 147,865 barrels per day for Iran and 265,748 barrels per day for Qatar. The study shows that increasing a country's potential payoff accelerates the convergence towards a stable, cooperative strategy.

Australia is well positioned to support the global energy transition, given its mature mining sector and rich and diverse mineral resources.

A step towards improved ESG credentials across the Australian mining sector is for mine developers, regulators, communities, investors and other industry stakeholders to be capable of integrating diverse types of ESG data into decision-making processes. This paper establishes the foundations for applying ESG mapping, a research technique that mobilises spatial data to analyse and compare extractive locations in terms of factors relevant to mining and exploration, at the scale of Australia. To do so, the paper first critically reviews 33 spatial ESG datasets available at national scale across six main themes: people, land uses, water resources, extreme events, nature conservation, and governance. The paper then provides two proof-of-concept applications of ESG mapping to the Australian mining context and draws on these preliminary applications to propose a program of research aiming to fully utilise this technique to inform decision makers.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"105 ","pages":"Article 105592"},"PeriodicalIF":10.2,"publicationDate":"2025-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143877510","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}

The results show that the abundance of natural resources has a positive effect on entrepreneurship for both men and women, although this effect is more pronounced for women. However, when natural resource is disaggregated into different type of resources, the impact become greater on male entrepreneurship than on female entrepreneurship. Furthermore, the results indicate an inverted U-shaped relationship between the abundance of natural resources and entrepreneurship. The study also highlights the crucial role of institutions in modulating the effect of natural resources on entrepreneurship and gender dynamic. Countries with better quality institutions, particularly those that fight corruption and ensure political stability; who put in place targeted policies to reduce inequalities in access to natural resources; who put in place programs to encourage female entrepreneurship in the natural resources sector; are better able to take advantage of natural resources to stimulate entrepreneurship.

In this respect, the shares of different environmental costs paid by mining enterprises in mine operating costs are of interest. In Turkey, mining administrations collect environmental costs such as forestry costs and environmental compliance fees from mining enterprises using different calculation methods. Mining waste management costs and rehabilitation costs, on the other hand, are the costs that mining enterprises spend independently from mining administrations during the mining operating period to ensure compliance with the legislation. Among these, rehabilitation activities, which are considered at the center of the study, are evidence that mining enterprises are mining in harmony with the environment in a sustainable framework with their specific activity stages. Rehabilitation costs spent for rehabilitation activities are costs made at different stages of mining operations. In Turkey, rehabilitation costs are spent by mining enterprises on their initiative, but ignored by the administrations and the public. Because these costs are not paid to the administrations, the public can't have information about how much money is spent. The calculation of the ratio of this cost to the operating cost by considering the duration of mining operations may help the administrations to determine the optimum calculation methods of environmental costs in the presence of other environmental costs and to consider these costs in total. In this study, it is aimed to see environmental costs as a whole by emphasizing the rehabilitation costs of mining enterprises. It is also aimed to contribute to the post-mining sustainable land use process and forestland use. Accordingly, the ratio of rehabilitation costs contributing to used and returned forest areas to operating costs was considered and compared to each other in order for the Ministry of Agriculture and Forestry to reconsider the calculation methods of different types of forest costs charged from mining enterprises. In this way, this study also aims to raise awareness about the costs charged by the administrations from the enterprises and how much these costs constitute a total cost in the eyes of different ministries &amp; administrations in terms of the annual costs of the enterprises. To this end, rehabilitation costs, waste management costs, environmental compliance fees, and forestry fees were compared together with their ratios to operating costs, and their changes according to mineral groups were analyzed. This study provides recommendations to policymakers on the nature and management of different environmental costs of mining enterprises that spend on environmentally compatible mining. This study also calculates rehabilitation costs per 1 ha of mining permit area and ton of mineral production.

Data from the Angoran lead-zinc mine are used to validate the model. The results indicate that increasing penalties and incentives within the range of 3 %–12 % of total investment accelerates contractors’ transition toward cooperation, leading to a stable equilibrium with the strategy of “government negotiation and contractor cooperation.' Furthermore, strengthening supervision and cooperation incentives by 5–15 % accelerates the stabilization of equilibrium, and cooperation is in an optimal state at 10 %, where the interests of both parties are effectively aligned.
