{"title":"Platform Dynamics and Economic Development","authors":"Danxia Xie, Buyuan Yang","doi":"10.2139/ssrn.3748484","DOIUrl":"https://doi.org/10.2139/ssrn.3748484","url":null,"abstract":"We build a novel dynamic model of two-sided markets which can be used to explore both intertemporal and cross-side pricing strategies of platform enterprise. This two-period model goes beyond the traditional two-sided market framework to examine the new intertemporal tradeoffs that a platform enterprise faces when formulating differentiating prices over time for different sides. With this dynamic framework, we analyze a new phenomenon of economic development, emerging \"Digital Villages\" in China, which obtain initial subsidies from e-commerce platform enterprises like Alibaba for their low-income dwellers as sellers. After these low-income sellers become more capable of running the online business through learning-by-doing, the e-commerce platform will charge them a higher fee. Recently, the economic growth of these \"Digital Villages\" has been phenomenal. Theoretical results based on our dynamic model indicate, if third-degree price discrimination between new and old online sellers in period 2 is allowed, the platform will charge sellers a lower fee in period 1 compared with the later period. Furthermore, when the cross-side network externality of each online seller is stronger than that of each online buyer or the learning-by-doing benefit each online seller obtains is high enough, the platform will provide subsidies for sellers in the first period. Moreover, some dynamic pricing strategies will change if this price discrimination on sellers is prohibited. Finally, we examine the effects of the price regulation on the member fees to heterogeneous groups as well as social welfare regarding the two-sided markets behind the \"Digital Villages\" within this new theoretical framework.","PeriodicalId":107258,"journal":{"name":"ERN: Networks (Topic)","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129680002","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}

The remote work, however, raised a number of concerns since the developer in Athens didn’t plan to relocate to Silicon Valley for the project. The solution they arrived at allowed the developer to remain in Athens and work remotely using an online platform called oDesk, which was aimed at addressing concerns of remote work, such as visibility, efficiency, and trust. Since the platform proved successful, they thought that the digital tool could benefit other firms and individuals looking for greater flexibility and innovative ways of working. Five years earlier - in 1998 - another company called Elance was founded by an MIT graduate and a veteran of Wall Street. They created a marketplace for small businesses, and in 2013 Elance and oDesk were merged. Two years later the combined firm was rebranded to Upwork, which is now the world’s largest freelancing website. The platform aims at “creating economic and social value on a global scale by providing a trusted online workplace to connect, collaborate, and succeed” (Upwork.com, 2018, in: Clausen – Khashabi – Kretschner – Seifried, 2018:5). The structure of this case study is a follow: i) we present the general features of the Upwork platform, ii) outline the key characteristics of the globalized service model, iii) review the views of Upworkers by the key dimensions of platform work (i.e., motivation, work content and skills, working conditions and formation of voices, and iv) focus on the issues raised during the interviews with platform workers. The final section summarizes the key lessons learned from the case study.","PeriodicalId":107258,"journal":{"name":"ERN: Networks (Topic)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132055136","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}

We examine how online sellers’ use of live chat influences their online traffic conversion into sales. Like brick-and-mortar stores, a fundamental task for online stores is to convert traffic into purchases, an important problem in retail service operations management. We argue that live chat can increase online sales conversion by performing the functions of informing and persuading. We explore how the two roles of live chat interact with existing information regarding sellers and their products, such as product descriptions, ratings, price, and reviews, as these types of information also influence consumers’ perceived product quality and help mitigate uncertainties in product fit to their needs. We apply a random-coefficient model in a Bayesian hierarchical framework and test the model using a panel dataset from Taobao, the leading C2C platform in China. Our results suggest that live chat has a positive impact on conversion and that the strength of this positive effect depends on seller and product characteristics. The positive effect is stronger when product information on web pages is less comprehensive (where live chat manifests an informative role), and when the perceived value of the product is higher (where live chat manifests a persuasive role) with either a higher product rating or a lower product price. Our results provide relevant and useful implications for online merchants and platform owners.","PeriodicalId":107258,"journal":{"name":"ERN: Networks (Topic)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123383489","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}

Firms set their prices and compete to capture market share. We compare cases where the firms can invest either independently (competition) or jointly (co-opetition) in congestion-reduction (CR) activities. Using a stylized analytical model, we find that when the market is covered (that is when everyone buys a product), the firm with a lower marginal CR cost earns more profit under competition than under co-opetition. When the market is uncovered, co-opetition is more profitable if the joint marginal CR cost is less than a threshold. We find that when the market is covered, neither firm makes any CR investment but when the market is uncovered, there will be a CR investment provided the marginal CR cost is lower than a threshold. Our analysis shows that when prices are regulated, firms under competition make CR investments but firms under co-opetition do not. The impact of proximity on each firm’s choice of location under competition and co-opetition are different. We find that if the marginal CR cost under joint investment is larger than a cutoff, then social welfare is also higher under competition than under co-opetition.","PeriodicalId":107258,"journal":{"name":"ERN: Networks (Topic)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129651369","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}

Home cooked food sharing platforms, as a quintessential illustration of the sharing economy, aim at improving public health by providing healthy food to those who do not have time to cook from home. Although the economic benefits derived from sharing economy are widely researched and acknowledged in theory and practice, however, the understanding about how sharing economy affects non-economic welfare (e.g., consumer health) is lacking. In a context of a home cooked food sharing platform, we conduct an empirical study to examine the question of whether sharing economy helps consumers to improve their dietary quality and develop healthy eating habits. We collected data from a popular Chinese mobile kitchen sharing platform and used manual coding and machine learning methods to measure food healthiness of over 180,000 unique dishes. We studied both food provision and consumption on the platform, and found that sellers receiving more orders and earning more revenue tend to reduce the provision of healthy food over time, while consumers who prefer healthy food are more likely to leave the platform. Our unfortunate findings indicate that without interventions, sharing economy may lead to negative and even harmful consequences because of the misaligned interests of home cooks and consumers.","PeriodicalId":107258,"journal":{"name":"ERN: Networks (Topic)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115389135","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}
