This paper utilizes a Salop circular city model featuring a single digital platform, two sellers, and a continuum of consumers to investigate the impact of probabilistic selling on the profits of the digital platform and sellers. We demonstrate that when the consumption utility is relatively low and product differentiation is at a moderate level, the market is in partial coverage. Offering appropriate probabilistic selling products in such cases expands the market, benefiting the digital platform, sellers and consumers simultaneously.

Customer lifetime value (CLV) is the total monetary value of transactions or purchases made by a customer with the business over an intended period of time and is used as a means to estimate future customer interactions. CLV finds application in a number of distinct business domains, such as banking, insurance, online entertainment, gaming, and e-commerce. The existing distribution-based and basic (recency, frequency, and monetary)-based models face limitations in terms of handling a wide variety of input features. Moreover, the more advanced deep learning approaches could be superfluous and add an undesirable element of complexity in certain application areas. We, therefore, propose a system that is able to qualify as both effective and comprehensive, yet simple and interpretable. With that in mind, we develop a meta-learning-based stacked regression model that combines the predictions from bagging and boosting models that are found to perform well individually. Empirical tests have been carried out on an openly available online retail dataset to evaluate various models and show the efficacy of the proposed approach.</p></div>","PeriodicalId":100776,"journal":{"name":"Journal of Economy and Technology","volume":"1 ","pages":"Pages 197-207"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949948823000045/pdfft?md5=3838da8083f490080bc4493a6efe14df&pid=1-s2.0-S2949948823000045-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135429349","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}

Unlike existing primal-dual decomposition or consensus methods, this paper proposes a cutting-plane-based distributed algorithm considering a peer-to-peer (P2P) communication network, which enables asynchronous coordination among PEVs. First, an equivalent surrogate model is established by exploiting the duality of the original optimization problem, which masks the private information of individual users by equivalent transformation. Then, a cutting-plane based algorithm is derived to solve the surrogate problem in a distributed manner with intrinsic superiority to cope with various asynchrony. Critical implementation issues, including distributed initialization, distributed cutting-plane generation, and localized stopping criteria, are discussed in detail. Numerical tests on IEEE 37- and 123-node feeders with actual data illustrate that the proposed method is resilient to several asynchronies and admits the plug-and-play operation mode. The proposed methodology is expected to provide an alternative path toward the robust protocol for PEV charging.</p></div>","PeriodicalId":100776,"journal":{"name":"Journal of Economy and Technology","volume":"1 ","pages":"Pages 29-47"},"PeriodicalIF":0.0,"publicationDate":"2023-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50189037","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim is to provide policy recommendations based on the simulation results of the model, which reproduces five representative scenarios of distributed energy systems. We also compare our simulation results with those obtained from a set of agent-based models. Our analysis shows that the most effective way to achieve a low-carbon transition is by combining two approaches: limiting the use of high-carbon energy sources through certain market rules and reducing energy consumption. We further obtain different paths of low-carbon transition based on phase diagrams that do not harm the economy. For developed countries, the most feasible approach is to directly increase the market regulation ratio. For countries or regions with middle-level technical and energy conditions and relatively high energy consumption, such as some Eastern European countries, reducing energy consumption and then implementing low-carbon energy incentives policy is the best strategy. Finally, for countries or regions with lower technical and energy conditions, such as African countries, the main task is to improve energy capacity to increase the possibility of a low-carbon transition.</p></div>","PeriodicalId":100776,"journal":{"name":"Journal of Economy and Technology","volume":"1 ","pages":"Pages 1-15"},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50189039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
