Sponge City (SC) concept has been promoted currently, as part of the wider scope of Nature-based Solutions (NBS) as sustainable measure that can be adopted to build resilient cities. However, Pakistan is still far behind in adapting such new practices. Its major cities like Karachi suffer from urban flooding and poor landscape management producing unhealthy urban environments. This study examines the familiarity and willingness of the experts related to architecture, urban planning and environmental development in adapting the concept of SC and the existing practical limitation perceived by these experts in Karachi for SC implementation. It employed a structured questionnaire survey administered to stakeholder groups to ascertain the status of knowledge amongst them related to NBS and SC. The research findings revealed that more than 50 % of experts are familiar with the concept of NBS and are willing to take part in implementing the SC initiatives in Karachi. At the same time, a significant majority of experts (74 %) are of the view that the absence of open and green spaces has a negative impact on quality of life in Karachi. However, most experts (72 %) consider the lack of government support as one of the major hinderances, while others consider high maintenance costs, shortage of skilled individuals and technology as barriers in adapting and implementing the SC concept in Karachi. This research subsequently identifies what could persuade experts to innovate SC concept within their practices. It emphasizes the urgent need for stakeholders and experts to collaborate with policy makers, advocating for a shift in mindset among both educated professionals to uninformed residents to drive meaningful change in the society.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"165 ","pages":"Article 103564"},"PeriodicalIF":7.0,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144892918","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}

The posted prize, entry fees, and productive resources promised to potential entrants jointly determine firms’ decisions to enter the competition and their effort supply. We characterize the respective optimal contests for two objectives: (i) maximizing total effort in the contest and (ii) maximizing the expected quality of the winning product. We show that the optimal contest induces the entry of only the two most efficient firms when the sponsor can jointly set entry fees and allocate productive resources. The resource allocation plan in the optimum may favor the initially more competent firm and thus promote a “national champion” instead of leveling the playing field, and the optimum depends on the nature of the R&D task and effort cost profiles of the firms. Our analysis sheds light on the roles played by these instruments in shaping optimal research contests.</div></div>","PeriodicalId":48409,"journal":{"name":"Journal of Economic Behavior & Organization","volume":"238 ","pages":"Article 107168"},"PeriodicalIF":2.3,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893206","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}

It is found that (1) Fintech positively impacts the reduction of CAI in both the short and long term; (2) Renewable energy consumption initially increases CAI in the short term, but contributes to decreased CAI in the long term; (3) The climate policy uncertainty similarly exhibits an asymmetric effect on CAI, exacerbating it in the short term and showing uncertainty in the long run. These results highlight the importance of designing stable and predictable climate policies to shape market expectations and encourage low-carbon investments.

Building a choice model is a complex, semi-structured process that involves a combination of prior assumptions, behavioural theories, and statistical methods. This complex set of decisions, coupled with diverse workflows, can lead to substantial variability in model outcomes. To investigate these modelling processes, we introduce the Discrete Choice Modelling Serious Game (DCM-SG), a novel tool that mimics the workflow of choice modellers and tracks the modelling decisions participants make. In our application, participants developed models to estimate willingness-to-pay values for reducing noise pollution. Their actions were tracked, enabling analysis of workflow patterns and modelling strategies. Forty participants, most with over five years of experience, completed the game. Our contributions are twofold. Methodologically, the DCM-SG captures sequential data on modellers’ workflows, which we analyse using telemetry and sequential pattern mining techniques to uncover dynamic patterns of in-game tool usage, phase transitions, and model specification approaches. Substantively, there was a strong preference for data visualisation and frequent specification of simpler models (Multinomial Logit), alongside attempts to specify more complex models. These findings suggest that in time-constrained or resource-limited settings, modellers may underexplore important factors such as covariates, non-linearities, and complex specifications. Moreover, participants who engaged more thoroughly in data exploration and iterative model comparison consistently achieved superior model fit and parsimony. These results demonstrate how sequential data from the DCM-SG can uncover variations in modelling practices and provide a foundation for understanding the art of choice modelling.</div></div>","PeriodicalId":46863,"journal":{"name":"Journal of Choice Modelling","volume":"56 ","pages":"Article 100562"},"PeriodicalIF":2.4,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144893393","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}
