The central question involves the trade-off between interaction quantity and content quality, and its impact on competition between an incumbent platform with a focal advantage and a high-quality new entrant seeking market entry. The study focuses on an agent’s utility function, examining the interplay between these factors and exploring strategies for platform decision-makers to maximize profits and benefits for their agents. The findings show that a high-quality non-focal platform has a strategic advantage in winning the market when agents prioritize content quality over the quantity of interactions. Policymakers should take into account the quality-driven impact on market efficiency and entry barriers.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"67 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140615700","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the absence of regulation, entry benefits both firms, but may harm downstream consumers because the upstream monopolist can set a high input price that would push downstream prices above the unregulated monopoly level. However, if a regulator caps the incumbent’s upstream and downstream prices, consumers and firms are better off after entry than under a price-cap monopoly. We extend our model to examine the concern that price caps may induce incumbents to forgo cost-reducing investments and dampen entrants’ incentives to self-provision the input.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"97 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139772517","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The paper demonstrates how to compute the equilibrium in each market structure. Assuming that firms cannot commit not to use all the pricing instruments at their disposal, mixed bundling by two-product firms emerges following each merger. While such behavior is a unilateral best response, the equilibrium consequences of these choices end up lowering total profits and welfare compared to the pre-merger markets suggesting that the opportunity to engage in mixed bundling cannot be the sole motivation for such mergers.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"83 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139772511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the model, we examine the seller’s decision about offering refunds for online reviews of his products, and each period consumer’s purchasing decision together with the first period consumer’s reviewing decision. Our main interest is whether a high-quality product seller offers a high amount or a low amount of cashback for an online review. We show that a lenient cashback policy for a review can be a signal of high quality of the product. Intuitively, a high-quality seller can offer a higher amount of cashback to a consumer who reviews, whether the review is positive or negative. This separation is possible mainly due to a difference in the second-period profits across types. We also briefly discuss the effect of the conditional review policy fostering fake reviews.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138682743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key objective of U.S. telecommunications policy is to promote policies that advance the availability of quality telecommunications services, with the goal of universal service. I develop a dynamic model of internet service providers’ entry, exit, and upgrade decisions. Estimating this model reveals the determinants of profits and variation in firms’ costs. I then use this information to simulate a variety of subsidy policies, and explore how the use of targeted subsidies can improve high-speed internet access.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"124 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138562718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To answer this question, I provide empirical evidence that connection speed greatly influences consumption of online video and that changes in speed therefore directly impact the entry of video content providers. I also present a framework to think about the incentives of broadband providers to offer a fast lane with access fees which has direct profits effects as well as indirect demand effects. Finally, by combining the empirical model with the theoretical framework in a counterfactual analysis, I show that a fast lane with access fees only increases entry for content providers with high fixed costs of content provision. Using a novel data set on household consumption of online content and broadband penetration in local markets to estimate a structural model of industry demand and supply, this paper is the first to provide empirical evidence on the industry-wide effects of breaking net neutrality.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"87 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We use five waves of panel data from the National Income Dynamic Survey (NIDS), which was conducted in South Africa between years 2008 and 2017. In the estimation we include a vector of observable individual and household characteristics and account for unobserved heterogeneity amongst individuals. The estimation results suggest that mobile phone ownership has a positive impact on the change in employment status from unemployed to employed. On the other hand, ownership of a computer by a household and computer literacy do not increase the likelihood of getting employed. The average probability of becoming employed increases from 54.2 % when no one among unemployed adults has a mobile phone to 57.4 % when all of them have a mobile phone, which is an increase of 5.9 %.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"8 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding the evolution and determinants of consumer demand in these situations can be quite important to economic policy formation, and especially so in network industries experiencing the entry of new services. In this study, we draw upon a database of over 180,000 individual household choices of fixed and/or mobile telephone subscriptions over 2003–2010 to improve insight into both the structure and evolution of consumer demand in such portfolio-choice settings. Congruent with our underlying consumer utility model, we find that cellphone service complements household member mobility: Households that are more often “on the go” favor mobile services. We also find the presence of network effects that impact the demand for mobile telephone services. Finally, we find that own- and cross-price elasticities of fixed and mobile telephony services demonstrate marked differences among demographic groups and across income levels.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"18 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138540347","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper considers the welfare effects of such exclusivity clauses for buyers, sellers and platforms in a platform duopoly with a seller membership fee. A setting with partially multihoming buyers and sellers is compared to one with partially multihoming buyers and singlehoming sellers. It is shown that exclusivity clauses predominately harm total welfare. Buyers suffer if sellers are exclusive on one platform, while platforms and sellers benefit from exclusivity clauses under certain conditions. In an environment with exclusivity clauses, when strong cross-group benefits and weak platform differentiation result in fierce price competition, exclusivity clauses can be welfare-enhancing.","PeriodicalId":45659,"journal":{"name":"Review of Network Economics","volume":"42 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2023-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82872870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
