This issue further complicates Europe's policy-making in its international relationships, especially with the greatest global economic powers like the United States (US) and China. To address the issues, this research aims to measure the spillovers of sustainable development between the EU, US, and China. To this end, it estimates their sustainability elasticities within 1973–2020, using the econometric technique of the SEY model, to examine the novel perspective of “Integrated Sustainability”. The results show that the sustainability elasticities are mainly positive, confirming the synergistic spillover effects of sustainability among the pillars of sustainable development. This finding adds the sustainability spillovers as the 4th pillar of sustainable development to the three traditional pillars including social status, environment development, and circular economy. In addition, the spillovers show a symmetric format among the sample countries, implying a balanced relationship with the other countries. According to this finding, policy-makers should strengthen international relationships with other countries and regions, including both Western and Eastern powers, by improving peaceful connections. In this policy-making, they should build a balanced regional and economic connection for an integrated world with a multilateral and flow-based governance system instead of unilateral and local-based governance.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"101 ","pages":"Article 102253"},"PeriodicalIF":6.2,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144242458","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}

This paper investigates the effect of gender differential in economic participation and foreign aid on productivity, specifically addressing three objectives: the efficacy of the medicine model of aid on productivity, the long-run effects, and the impact of aid shocks. Using panel Fully Modified Ordinary Least Squares (FMOLS), Dynamic Ordinary Least Squares (DOLS), and Augmented Mean Group (AMG) estimators, the study examines the long-run impact. The Panel Vector Error Correction Model (PVECM) is employed to analyse the effect of aid shocks. For robustness checks, employment indicators are substituted for economic participation metrics. Empirical findings from the baseline model affirm the medicine model's proposition regarding the implications of aid on the SADC but reveal that aid has a negative coefficient in its ordinary form. The extended model demonstrates a significant and long-run negative impact of foreign aid on productivity. However, when considering the interactive effects, aid combined with economic participation positively influences productivity. Notably, the interaction of foreign aid and female economic participation significantly enhances productivity more than aggregate or male economic participation alone. Additionally, aid shocks negatively affect male economic participation more than the aggregate, with female economic participation being the least impacted. The study underlines the importance of prioritising female economic participation in aid programs to promote broad-based growth in the SADC region. The study recommends that aid agencies focus resources on projects that enhance female economic participation and meticulously evaluate project outcomes upon completion.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"101 ","pages":"Article 102250"},"PeriodicalIF":6.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144196127","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}

This study investigates the complex interaction between socio-political factors and individual-level CE practices in Italy, addressing gaps in existing research that primarily focus on specific consumer behaviors or demographic characteristics. Particularly, utilizing probit and multivariate probit analyses on the 2021 AVQ “Aspects of Daily Life” dataset from ISTAT, the research examines how socio-political involvement, budget constraints, positive educational externalities, and demographic factors influence CE behaviors. The findings reveal that socio-political factors, particularly political trust in local governments, significantly influence circular practices, with higher trust associated with greater adoption of sustainable transportation and local products, while lower political engagement correlates with increased waste and reduced sustainability, highlighting the need for targeted educational initiatives and localized policies to promote a circular economy effectively.</div></div>","PeriodicalId":22033,"journal":{"name":"Socio-economic Planning Sciences","volume":"100 ","pages":"Article 102252"},"PeriodicalIF":6.2,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144169235","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}
