This study investigates the effect of gold and oil prices, including their price shocks, on Bitcoin price during two specific conflicts: the Russia-Ukraine war and the Israel-Gaza conflict. To achieve this, we employed the Vector Auto-Regression (VAR) method and wavelet coherence analysis. The data used spans daily observations from January 2022 to April 2024.The findings indicate that gold prices have a positive impact on Bitcoin prices. Specifically, there is a predominantly short-term relationship between gold prices and Bitcoin prices throughout the entire period under review, with this influence gradually decreasing over the medium and long term. Conversely, the relationship between Brent oil prices and Bitcoin prices during the same period shows that crude oil prices generally have a negative and insignificant effect on Bitcoin prices in the short term.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"99 ","pages":"Article 105405"},"PeriodicalIF":10.2,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142658083","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}

In this paper, we argue that in a context where Eskom electricity provision is often exclusionary, residents deploy diverse strategies to challenge this form of infrastructure violence. Drawing on over twenty months of ethnographic work, complemented with participant observations and semi-structured interviews, we demonstrate how resident-made electricity connections prove a critical and implicit part of the electricity infrastructure system. Building from a sociotechnical approach to infrastructure, we use the notion of ‘precarious power’ to explore the mix of agency and precariousness that are entangled in the everyday practices of ordinary people making electricity connections. We highlight that in improvising electricity access, residents in Witsand exercised their agency to circumvent and appropriate Eskom electricity. This paper contributes to an understanding of urban residents' everyday infrastructural experiences through an analytical frame that is neither dismissive of their agency nor celebratory of their struggles.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"154 ","pages":"Article 103228"},"PeriodicalIF":6.5,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142651569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When developers monetize their apps by charging users (or through in-app advertising), they must pay commissions to the app platform (or ad platform). Both platform markets are interconnected, as developers choose which market to use for monetization (paid or ad-funded). The model shows that app and ad platforms are substitutes for app developers. Thus, an imbalance between app and ad commissions induces some developers to choose inefficient business models. For example, if the app commission is lower than the ad commission, some ad-friendly developers may choose the paid business model even though they could generate a greater surplus from advertising from a social welfare perspective. This finding highlights the benefits of distinct platforms setting similar commissions. The model is also used to evaluate the impact of a non-price strategy implemented by the app platform to limit the ability of app developers to monetize through advertising. The analysis shows that the app platform can use this non-price strategy to increase its demand at the expense of the ad platform.</div></div>","PeriodicalId":48127,"journal":{"name":"International Journal of Industrial Organization","volume":"97 ","pages":"Article 103117"},"PeriodicalIF":1.7,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661687","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Releasing Green Belt land has been cited as a solution. This paper analyses new build development in the London region from 2011 to 2022, and confirms that Green Belt policy needs reform – local authorities in the Green Belt have the lowest housing delivery in the region, and car dependent ‘leap-frog’ development is occurring beyond the Green Belt boundary. The relaxation of Green Belt restrictions could greatly boost development, but would also risk producing car dependent housing. This research produces a new Travel Sustainability Index using census travel behaviour data, and analyses the travel patterns of residents in new build housing over the last decade. The conclusions are that more sustainable Green Belt development can be achieved by prioritising development in Outer London and through extending existing towns and cities in the Greater South East. Achieving this outcome will require improved regional planning coordination and infrastructure investment.</div></div>","PeriodicalId":48405,"journal":{"name":"Cities","volume":"156 ","pages":"Article 105574"},"PeriodicalIF":6.0,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142657756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
