This review delves into the literature on deep decarbonisation strategies within the power sector, examining the economic costs and associated challenges. Methodologically, over 2000 studies were screened, with 30 systematically reviewed to extract insights into transitional strategies and cost implications. The literature underscores the pivotal role of power generation in reducing greenhouse gas emissions, emphasising the urgency of substantial emissions reductions by 2050. While faster transitions to low-carbon power may incur higher costs initially, delaying the transition could lead to significant economic and environmental consequences. Two primary strategies emerge, one centred on renewable energy sources and another incorporating diverse low-carbon technologies. However, hybrid approaches that combine various technologies are highlighted as optimal for minimising costs and enhancing flexibility. In conclusion, this study highlights the importance of identifying cost-effective pathways for power sector decarbonisation, with implications for future research and policymaking to address the challenges effectively.</div></div>","PeriodicalId":100776,"journal":{"name":"Journal of Economy and Technology","volume":"3 ","pages":"Pages 22-33"},"PeriodicalIF":0.0,"publicationDate":"2024-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140784595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study proposes a two-stage model for analyzing the elasticities of production and economies of scale that arise from estimating singular knowledge production functions within a regional trade system. This model is tested for the case of the trade agreement of the United States, Mexico, and Canada (USMCA). The main results express that R&amp;D expenditures embodied in KIBS spillovers have a significant effect on the generation of innovation outputs, in each of the USMCA countries and, reveal increasing returns to scale.

These challenges are particularly evident in regions with complex geographies, such as the Andean region, where elevation differences and irregular topography pose significant obstacles to the development of electricity infrastructure. This study addresses these challenges by applying non-conventional strategies for transmission grid expansion, with a particular emphasis on adapting to the unique geographic features of the Andean region. To illustrate this, a case study called EC-45 bus system is developed using Ecuador as a country representative of the geographic diversity of the Andean region. Furthermore, this work presents a Mixed Integer Linear Programming (MILP) model that prioritizes the repowering and reconfiguration of existing lines over the construction of new lines. The methodology employed evaluates the investment required for the construction of new lines, considering construction costs for three site types (&lt;1000 meters above sea level (m.a.s.l.), ≥1000 m.a.s.l., and combined). Quantitative results show that using non-conventional solution methods can generate savings of up to 30.60% in investment costs compared to the solution provided by the Linear Disjunctive model. This approach offers a way towards more efficient management of resources, especially in countries with complex geographies such as the Andean one.</p></div>","PeriodicalId":100776,"journal":{"name":"Journal of Economy and Technology","volume":"2 ","pages":"Pages 31-46"},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949948824000192/pdfft?md5=bb2be00d5a7eb073498a10cc9726fb9b&pid=1-s2.0-S2949948824000192-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140767408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study addresses the need for a comprehensive analysis of Generative Pre-Trained Transformers (GPT) in the context of open-source disaster intelligence, a topic where existing literature remains fragmented. Employing a systematic approach, a query scheme incorporating 11 at. keywords was devised, resulting in the acquisition of 53 relevant studies. These studies were meticulously reviewed and synthesized to propose six dimensions of GPT-based open-source disaster intelligence, yielding critical insights into disaster management strategies. Within these 6 dimensions, 24 studies were categorized under “Social Media Analytics for Disaster Response” dimension, 7 on “Disaster Prediction,” 11 on “Disaster Management,” 5 on “Disaster Support Via Technology”, 3 on “Climate Change and Disaster Communication,” and 5 studies were classified under the “General Disaster Analysis” dimension. Leveraging advanced methodologies and machine learning driven tools such as PRISMA, Litmaps, and VOSviewer, this research not only identifies key trends and collaborative efforts but also provides valuable bibliographical insights for researchers and practitioners in the field. For example, the co-citation analysis demonstrated a total of 3703 authors, among whom 51 authors garnered a minimum of 10 citations, leading to the identification of 3 distinct clusters.

China, as a prominent emerging nation, holds a significant position in the worldwide environment. However, it is imperative to acknowledge that China's ecological impact is substantial, as evidenced by its considerable contribution of almost one-third of the total global carbon emissions in the year 2021. The encouraging aspect lies in the emergence of China as a significant economic power, which may be attributed to the positive impact of technological advancements. The scientific literature suggests that the use of novel technologies has the potential to contribute significantly to mitigating environmental degradation. The objective of this study is to investigate the impact of China's economic growth and technological advancements on ecological footprint throughout the period spanning from 1985 to 2020. This study utilizes the ecological footprint concept as a means to assess environmental degradation in China. The ARDL cointegration methodology is utilized to estimate the long- and short-term impacts, and the outcomes are validated through the application of further cointegration regression techniques. Furthermore, the pairwise Granger causality analysis is employed to examine the causal links among the variables. The empirical evidence suggests that economic expansion exacerbates environmental degradation in China, whereas technological progress plays a mitigating role in addressing this issue. The results of the study also demonstrated a bidirectional causality between economic growth and technological innovation, suggesting that China's economic growth and technological progress mutually reinforce one another. The paper proposes green technical solutions that have the potential to mitigate environmental degradation while maintaining economic growth. Sustaining long-term economic prosperity necessitates the implementation of both carbon emission taxation and strategic investments in environmentally beneficial technologies.</p></div>","PeriodicalId":100776,"journal":{"name":"Journal of Economy and Technology","volume":"1 ","pages":"Pages 94-107"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949948823000069/pdfft?md5=cc5a83c6248e97867f8c3c2c74dfac1f&pid=1-s2.0-S2949948823000069-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"92045651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
