This increase in comovement is mainly associated with cash flow news and firm-specific information. We find that the idiosyncratic shocks to customers diffuse through the customer-supplier network and aggregate into a systematic risk, which affects suppliers' expected returns. Using a long-short portfolio based on exposure to aggregated customer risk, we realize annual excess returns of 3.1% (value-weighted) and 6.11% (equal-weighted), respectively. The customer risk factor cannot be explained by market, size, book-to-market, or momentum factor. Consistently, we also find a positive relationship between exposure to the customer risk factor and cost of equity capital.","PeriodicalId":319022,"journal":{"name":"Economics of Networks eJournal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117075697","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 theoretical model illustrates how an influencer strategically reacts to various platform policies. Using unique data from the largest Chinese Question-and-Answer platform, we analyze the content provisions of all the influencers with more than 10,000 followers on the platform over two years. Using an instrumental variable approach, we find that a simple OLS method is likely to under-estimate the incentive of peer recognition for content provision because the reputational and privacy concerns make the badge policies counterproductive. Our findings suggest that while badges in the Q&A platform make it easier for users to identify the quality of an influencer, those badges that include a strong connotation may also limit the content contribution since influencers have concerns about their reputation management and privacy. The paper indicates from an empirical perspective that platforms’ attitudes towards real-name policies may depend on the trade-off between incentives for content creation and content regulation. Policies based on reputation and privacy may have a backlash against policies that encourage traffic.","PeriodicalId":319022,"journal":{"name":"Economics of Networks eJournal","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116413728","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 find that FoFs exhibit PB bias, a disproportionate preference for hedge funds serviced by their connected PBs. This PB bias is stronger when the cost of hedge fund due diligence is higher relative to capital and when the FoF’s management firm generates higher prime brokerage fees. PB bias also predicts FoF performance: the highest PB-bias quartile outperforms the rest by 2.08%–2.45% per annum after adjusting for differences in their risks.

Fourth, we compare the policy outcomes in the first and the third cases above and show that if one city switches to a Rawlsian or more egalitarian objective when the other city remains utilitarian, the aggregate economy becomes less egalitarian.

It involves the main findings of this research wave and explores the development of internet penetration among the Greek population by providing comparative data on several aspects of the respondents’ internet-related behavior between all three WIP waves (2015, 2017, 2019). These aspects pertain to digital use, access and divides, online activities and social capital, internet reliability and fake news, online victimization and privacy, political efficacy and freedom of expression. Data were collected by 1,208 interviews over the phone on a structured questionnaire (based on WIP guidelines and included some additional national questions of theoretical interest) and manually transferred to an online platform using RM+ software and then to statistical analysis software. The dataset was weighted according to the 2011 Population Census and the Labor Force Survey.

Strategic pricing, technology-based platform protection, and deterrent enforcement such as legal and moral measures are viewed as antidotes to piracy. We examine the effects of deterrent enforcement on platform protection and price choices. We develop an analytical model in which the content provider determines the price of content and the platform determines the platform protection. We find that platform protection and deterrent enforcement establish different relationships, depending on the context—complementation in the piracy region, substitution in the threat region with positive platform protection, and independence with zero platform protection in the remaining regions. Surprisingly, when the deterrent enforcement is moderately high, if platform protection is adopted, the optimal price is larger than the monopoly price in the no-piracy region without threat. More surprisingly, in the same deterrent enforcement region, if the platform executes the platform protection, the users, content provider, and platform all will fall into a middle-protection trap. In other words, a “win-win-win” result would arise if the platform gives up its protection.","PeriodicalId":319022,"journal":{"name":"Economics of Networks eJournal","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132023262","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}

With a growing global data sphere, differences across platforms with exclusive access to big data intensify.

They focus on the nonrivalry of data to show that the same dataset should be available across firms to spur innovation. Yet, this contrasts with the desire for privacy by individuals and the fear of creative destruction by firms. We provide a systematic literature review to inform IS research on options to solve the problem of big data misallocation. Specifically, we synthesize academic progress for improving data-sharing approaches. We show that technological options will be available soon that will let individuals decide to whom they grant access to their data.
