While existing literature primarily focuses on the relationship between development aid and migration in origin–destination dyads, this study addresses the neglected role of transit countries. Using 2019 survey data on migrants in Libya and employing matching methods to mitigate selection bias, we find that humanitarian assistance does not significantly influence migrants’ intentions to migrate onward to Europe. However, the analysis reveals a significant reduction in return intentions to countries of origin, with an estimated effect indicating a relative decrease of up to 59% among aid recipients compared to non-recipients. This study complements existing literature by providing micro-level evidence that underscores the importance of transit countries in the aid-migration relationship. The findings suggest that humanitarian aid provides critical relief, deterring return migration without encouraging onward migration by loosening financial constraints. Policymakers should design aid strategies that reflect the unique dynamics of transit countries, prioritizing humanitarian assistance for its intended purpose of relief rather than as a tool for managing migration flows, where its effectiveness may be limited.</div></div>","PeriodicalId":48463,"journal":{"name":"World Development","volume":"191 ","pages":"Article 106980"},"PeriodicalIF":5.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738504","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 natural water flows are restored the inundated areas most often may be many times larger than the hitherto existing ones. This requires rethinking of existing land use in artificially-drained mining areas by using tailor-made spatial planning policy to address future changes in water conditions. The main goal of this paper is to show that in such areas the current prevalent practice of classical hydrological modeling using only the base flood translates into inadequacies in spatial planning policies. To accurately model the hydrological hazard in such areas, water equal to or greater than the 500-year flood as well as other flood-related geohazards and risks must be taken into consideration. The current practice and omissions can now be precisely updated and satisfied by the author's site-specific decision support tools, namely (1) hydrological hazard frameworks based on (2) relative elevation models. This article is the first in a series describing the use of the author's tools in spatial planning policy. Regardless of the restoration of natural water flows, these tools conceptualize, simplify and optimize spatial planning and environmental policies for mitigation of flood-related geohazards and risks in artificially-drained mine subsidence areas and constitute the key research finding of this paper. Due to the massive extent of mining and post-mining areas around the world, these decision support tools for spatial planning policy are applicable globally and can bring tangible and far-reaching benefits to regional economies and local communities.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"103 ","pages":"Article 105572"},"PeriodicalIF":10.2,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143748527","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}

One critical element of energy infrastructure at this project planning stage is construction cost overruns and time delays. Using an original dataset 50 % larger than those in the previous literature, this study examines the cost overrun risks facing 662 energy infrastructure projects across 83 countries built between 1936 and 2024, covering $1.358 trillion in investment and a total capacity of >400 Gigawatts. We find that more than three-fifths of the projects experienced cost overruns, with these overruns being particularly prominent in projects exceeding 1561 MW in capacity. Positively, the escalation rate in cost overruns has been declining since 1976. However, the patterns of cost overruns varied by fuel source. For instance, nuclear and fossil thermal projects exhibited higher cost escalation rates over time, whereas solar power projects showed a decline. Critically, both hydrogen and carbon capture and storage (CCS) projects exhibited significant time and cost overruns, casting doubt on their ability to rapidly be scaled up to address climate change or meet energy and climate policy priorities. We draw from these insights to chart future research gaps as well as salient policy recommendations.</div></div>","PeriodicalId":48384,"journal":{"name":"Energy Research & Social Science","volume":"123 ","pages":"Article 104057"},"PeriodicalIF":6.9,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746545","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}

I use a Tullock (1980) style contest to analyze how the free-rider problem, the extent of the deadweight loss and bias in the policy process interact in determining the social loss resulting from lobbying activity. For plausible parameter values, an increase in the ability of the group potentially subject to the transfer to overcome the free-rider problem worsens social welfare by increasing expenditure in the transfer-seeking game even as it makes the distortion inducing transfer less likely. There are also plausible parameter values under which an increase in the bias of the policy process towards the group seeking the transfer raises social welfare by reducing expenditures in the transfer seeking game even as it makes the distortion inducing transfer more likely.</div></div>","PeriodicalId":51439,"journal":{"name":"European Journal of Political Economy","volume":"87 ","pages":"Article 102673"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
