Energy burden measures the percentage of income spent by a household on energy for heating, lighting, air conditioning, cooking, etc. Households with greater energy burdens may have to make tradeoffs between paying utility bills and medical, housing, or other expenses. Some limited quantitative and case study research indicates that underprivileged groups suffer larger energy burdens, often attributed to lower income levels. Our study is the first to examine the phenomenon nationally as well as investigate the drivers of energy burden on households across the United States. Our examination of energy burden across all measurable census tracts in the United States (<em>n</em> = 64,835) finds that even when accounting for income, majority African American census tracts face significantly increased average energy burden with largely Latinx census tracts less challenged. To explore this social occurrence, we examine the intersectionality of race, income, and structural challenges in these neighborhoods. We find that average building age and homeownership rates impact energy burden and are two factors that overburden African American households. We discuss some historical and programmatic factors that our analysis points to as potential causal mechanisms for the higher energy burden in African American communities. The goal of a just energy transition to lower carbon emissions requires that policymakers understand that energy burden is not simply a matter of income, but a complex set of historical and structural causes that face households with multiple vulnerabilities.</div></div>","PeriodicalId":48384,"journal":{"name":"Energy Research & Social Science","volume":"127 ","pages":"Article 104207"},"PeriodicalIF":6.9,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588459","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}

IDV cultures are characterized by greater individual freedom (especially reproductive and religious), rule of law, and human rights than COLL ones. Despite a partial worldwide shift toward IDV, these country differences are relatively stable. Previous research explains them as a function of differences in wealth, climate, pathogen prevalence, Western Church policies, and more. We test a new theory: prevalent types of agriculture 100 years ago and earlier still explain IDV-COLL differences. We analyze two strongly correlated IDV-COLL versions, by Minkov-Kaasa and by Schwartz, as well as a new measure of objective COLL-IDV for 84 nations, consisting of household size, gender inequality, LGBT rights, and rule of law. We also use the Minkov-Kaasa IDV-COLL index for the 50 US states. For all national IDV-COLL/COLL-IDV measures, across the whole country sample, and across 35 culturally independent nations (thus avoiding autocorrelation), historically prevalent dairy farming is associated with IDV, whereas nomadic herding and shifting cultivation are associated with COLL. Across 48 US states, historically prevalent dairy farming predicts IDV, plantations predict COLL. Agriculture always produces the strongest direct effects. The effects of the other predictors are inconsistent, with the seeming exception of wealth. Yet, some environmental predictors have a distal effect on IDV-COLL, mostly through the mediation of agricultural types.</div></div>","PeriodicalId":48463,"journal":{"name":"World Development","volume":"195 ","pages":"Article 107117"},"PeriodicalIF":5.4,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144587725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the study examines the moderating effect of the rule of law on the impact of natural resource management on entrepreneurial activity and SME growth across the 11 selected ECOWAS nations. The study employs panel data ranging from 2006 to 2022 (i.e., 17 years), using two (2) advanced econometric techniques (Heteroskedasticity Panel Corrected Standard Errors (HPCSE) and Feasible Generalized Least Squares (FGLS). The findings indicate the presence of a resource curse in the ECOWAS region, wherein the abundance of natural resources exerts a negative effect on entrepreneurial activity and the growth of SMEs. Moreover, the rule of law proves to be ineffective in mitigating these negative outcomes and its interaction with natural resource rents reveals only a weak relationship, suggesting that legal frameworks within ECOWAS countries are insufficient to mitigate the adverse impacts of resource dependency. In contrast, population growth and government expenditure on education exhibit a positive influence on entrepreneurial activity and SME growth, underscoring their role in stimulating both demand and supply within the regional economy. Practical policy recommendations include prioritizing education spending and implement legal and institutional reforms as central policy measures to reduce overreliance on natural resources and drive sustainable business growth.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"108 ","pages":"Article 105674"},"PeriodicalIF":10.2,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596634","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}

From a methodological perspective, the analysis is conducted via a wavelet-based method. The dataset includes natural gas, copper, palladium, and cobalt futures prices, whose time series cover a fourteen-year time span (2010-2024), while geopolitical risk is measured through the well known text-based geopolitical risk (GPR) index by Caldara and Iacoviello. The study is supported by an in-depth geopolitical discussion, analyzing events and dynamics relevant to the current international context. Our investigation shows different degrees of correlation between geopolitical risk and the above-mentioned commodities. From an overall perspective, commodities with a long-standing history of application tend to exhibit a more straightforward connection with geopolitical dynamics. In contrast, those that have recently gained prominence in the energy transition — especially newer entrants — show weaker and less consistent signals. In this respect, despite its widespread use in the literature, we infer that the GPR index has certain limitations when used to explain dynamics affecting rare and critical elements — particularly those sourced from geographical areas that are not regularly covered by mainstream media. The issue of the GPR index’s adequacy in such contexts appears to be largely overlooked in current academic sources. Recognizing that the energy transition is driving a paradigm shift from a geostrategic standpoint requires a critical awareness when employing such indexes. At the same time, it calls for rethinking how risk indexes are designed, so that they better reflect geopolitical phenomena linked to the new centers of gravity emerging from the energy transition. The results are directed towards policymakers and regulators, who are called upon to govern the energy transition with a focus on the availability of critical materials in the coming decades.</div></div>","PeriodicalId":20970,"journal":{"name":"Resources Policy","volume":"108 ","pages":"Article 105666"},"PeriodicalIF":10.2,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144588309","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}

If farmers under-remember cattle health events, this will reduce their incentive to invest in preventive technologies. We implemented a field experiment in western Kenya to study if relieving memory constraints increases demand for a livestock disease prevention technology. We trained and incentivized study participants to keep simple written records of cattle disease events, health expenditures, and milk production outcomes for a period of three months. We then provided a paper template to help summarize the information in the record books. We find this intervention nearly doubled demand for the preventive technology, and evidence suggests that the record-keeping increased recall of disease events.

This study develops an announcement jump model to disentangle the option‐implied volatility specifically associated with monthly World Agricultural Supply and Demand Estimates (WASDE) report releases. Using data for corn, soybeans and wheat, we find evidence that these options are overpriced primarily with respect to the realised volatility observed on announcement days rather than on normal trading days, suggesting the existence of an announcement volatility risk premium. A long straddle position, formed by the simultaneous purchase of a call and a put option and providing protection against large price movements in either direction, generates a significant loss of 3%–7% only on report release days. Furthermore, we show that this negative return is unlikely driven by exposure to other risks and is more pronounced when the experts' forecast dispersion is high, indicating that market participants pay to hedge extreme volatility induced by announcements in agricultural markets.","PeriodicalId":14994,"journal":{"name":"Journal of Agricultural Economics","volume":"13 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2025-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144594001","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}
