As a form of fraud, scrounging can substantially affect platform efficiency and has emerged as a critical issue in the contemporary digital economy and Web 3.0 sector. This underscores the necessity to model scrounging behavior and implement strategies to mitigate it. In this study, we develop a model that characterizes scrounging behavior in digital platform promotions and provides a theoretical explanation. We also introduce Palm as Decentralized Identifiers (DIDs), offering Proof-of-Human (PoH) to reduce fake identity prevalence. Unlike traditional blockchain technology, Palm as Decentralized Identifiers (DIDs) utilizes the Human Chain approach, ensuring equitable treatment of all users within the system. We demonstrate the effectiveness of our system in mitigating scrounging and explore its prospective applications in tackling real-world challenges in the digital and Web 3.0 economies.","PeriodicalId":29662,"journal":{"name":"International Studies of Economics","volume":"19 4","pages":"508-531"},"PeriodicalIF":0.5,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ise3.85","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143187284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, factor market distortion impedes China's green development through factor mobility and resource allocation. Under such circumstances, we detect whether and how factor market distortion affects green innovation from various perspectives in the case study of China's Sustainable Development Demonstration Belt. The findings demonstrate that the distortion has a pronounced inhibiting effect on the green innovation growth in the study area. For the eastern and more-developed cities, factor market distortion considerably inhibits green innovation improvement, while the impact is less pronounced in the western (or central) and less developed cities. Furthermore, the factor market distortion negatively affects green innovation through some effective paths, like energy efficiency and environmental regulation. From a spatial perspective, the green innovation's spillover effect could be reduced by both the distortions of the labor market and capital market. Thus, this study would provide strong theoretical support for enhancing the factor market system and improving the multiregional green innovation power in China, as well as scientific suggestions on transitioning to China's sustainable development.","PeriodicalId":29662,"journal":{"name":"International Studies of Economics","volume":"19 3","pages":"353-373"},"PeriodicalIF":0.5,"publicationDate":"2024-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ise3.89","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142137862","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An event-study difference-in-differences approach is employed to facilitate identification, which compares changes in the stock market participation behaviors of households that experience children's marriage with households that experience it later as well as households that never experience it. Exploiting household-wide variations in exposure to children's marriage using the China Family Panel Studies data over the 2010–2020 period, this paper finds that 2 years after children's marriage, households significantly enhance their likelihood of participating in the stock market. Households' willingness to participate increases by 1.1 to 1.6 percentage points depending on specifications. This paper's finding supports time-varying risk aversion at the household level. Mechanism analysis indicates that children's marriage raises household risk preferences because it mitigates parental old-age support concerns and alleviates households' consumption commitment to housing and children.","PeriodicalId":29662,"journal":{"name":"International Studies of Economics","volume":"19 3","pages":"448-468"},"PeriodicalIF":0.5,"publicationDate":"2024-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ise3.84","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141270903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using the difference-in-difference model, we find that command-control environmental regulation can significantly improve the environmental performance of heavily polluting firms. This result still holds after a sequence of robustness tests. The analysis of the economic mechanism indicates that the new environmental protection law mainly contributes positively to the environmental performance of high-polluting firms by improving the quality of their environmental investments and pollution treatment disclosures, and by reducing the government subsidies they receive to improve the environmental performance of high-polluting firms. Meanwhile, the new environmental protection law has a more pronounced impact on heavily polluting enterprises in the eastern region, with imperfect internal control, stronger environmental regulations, more distant political connections, greater pressure on regional GDP growth and weaker industry competition. This paper confirms the effectiveness of the new environmental law in improving environmental performance of heavily polluting enterprises in pursuit of carbon peaking and carbon neutrality goals, and provides new evidence to test the weak Porter hypothesis in the context of transition economies.","PeriodicalId":29662,"journal":{"name":"International Studies of Economics","volume":"19 3","pages":"406-430"},"PeriodicalIF":0.5,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ise3.77","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140998576","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
