However, social media are only a part of the daily media diet of an average consumer (<span>Allcott and Gentzkow, 2017</span>; <span>Allen et al., 2020</span>). The aim of this paper is therefore to examine partisan news exposure with respect to the entire media diet. We develop a partisan selective exposure index that indicates the over-representation of partisan political opinions in individual daily news consumption. Our analysis of data from a survey of 4,000 people in France shows that on average, partisan exposure is low when social media are excluded. Our estimations also indicate that social media consumption increases selective exposure to partisan content. While the youngest and the less educated appear to be less exposed to partisan content in the absence of social media, our results suggest that this is no longer the case when social media are included in the news diet. Finally, we show that the more people declare extreme (right- or left-wing) political views, the more they are over-exposed to like-minded content.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"60 ","pages":"Article 100992"},"PeriodicalIF":2.8,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48185812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We analyze 32,367 venture capital deals between 2010 and 2020, and 392 tech start-up acquisitions by Google, Facebook, Amazon, Apple, and Microsoft. Results obtained with fixed effects panel and differences-in-differences estimators reveal a positive, statistically significant, average effect of Big Tech start-up acquisitions on worldwide, venture capital activity. Positive effects were also found for the United States and Europe. However, the findings suggest that the effects are transient and fade away after several quarters. Because venture capitalists fund start-ups to enable entrepreneurial innovation, this approach also informs our understanding of the repercussions of these acquisitions on the start-up innovation ecosystem. The large number of observations over an extended period unlocks insights into historical patterns that are relevant for the design of digital platform policies.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"59 ","pages":"Article 100973"},"PeriodicalIF":2.8,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0167624522000129/pdfft?md5=42abac0dcec90ccfe5f23815e87bfa90&pid=1-s2.0-S0167624522000129-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41880008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rapid strides in information and communication technology (ICT) through cost-effective and reliable telecommunications have facilitated multinational firms to outsource complex production activities across borders over the years. While the rise of GVCs to prominence has coincided with the ICT revolution, there is very little systematic empirical evidence at the firm-level documenting the nexus between digitalization of firms and their participation in GVCs. By using rich firm-level data for a sample of 24,839 firms across 52 countries spanning the period 2006–2018, we empirically test the importance of digitalization in deepening GVC participation. After correcting for potential biases arising from self-selection and reverse causality, our empirical analysis shows that digitalization by firms positively influences GVC deepening. Our results are quite robust to various measures of GVCs and digitalization. Further, we also document how digitalization boosts GVC integration of firms that are financially constrained.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"59 ","pages":"Article 100972"},"PeriodicalIF":2.8,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0167624522000117/pdfft?md5=0f9b5d29032cbd6aeacb8d167227db91&pid=1-s2.0-S0167624522000117-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43918240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This revived a much needed debate over the privacy issues associated with online proctoring of exams, while the validity and fairness of unproctored exams were increasingly questioned. With a randomized control trial, we estimate the effectiveness of prior warnings as a means of discouraging academic dishonesty in exams. We use original, non-intrusive technologies to surreptitiously identify cheating in a series of unproctored assignments and send a targeted warning to half of the students who were identified as cheaters. We then compare their cheating behavior on the final exam with the behavior of the group of unwarned cheaters. The warning proves effective but does not completely eliminate cheating, as some students’ cheating strategies become more sophisticated following issuance of the warnings. We conclude that switching traditional exams to online mode should be accompanied by proctoring. When proctoring is not possible, credible and effective anti-cheating technologies should be deployed together with adequate warnings.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"58 ","pages":"Article 100959"},"PeriodicalIF":2.8,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0167624521000470/pdfft?md5=6259ddc091de0e9d3ae59b7b329ac645&pid=1-s2.0-S0167624521000470-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48019931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present paper advances the theoretical analysis of the interaction between economic espionage and counter-espionage, and presents a first approximation to an inquiry into the rationale for the influence of market competition in its dynamics. The proposed model assumes a country with a one-market economy open to international trade whose product is supplied by domestic firms. Moreover, successful economic espionage implying market entry of foreign firms would harm domestic welfare. Considering counter-espionage policy as entry barrier and sufficient efficiency in espionage and counter-espionage efforts, the analysis of the benchmark case characterized by no foreign consumer and one foreign firm suggests that demand characteristics play an important role in the complex influence of competition in espionage. Irrespective of this, optimal counter-espionage effort is always positive although negatively affected by competition.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"58 ","pages":"Article 100964"},"PeriodicalIF":2.8,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46361413","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
