We extend the Helpman, Melitz and Yeaple (2004) model to include the opportunity for firms to pay lower fixed export costs by exporting indirectly via well-established e-commerce platforms. SMEs self-select into the indirect exporting mode. In response to the development of the Internet, fixed costs of indirect exporting fall at a higher rate than fixed costs of direct exporting. Consequently, SMEs tend to account for a larger share in total exports as the Internet develops. Using two samples from the Exporter Dynamics Database, we find supporting evidence that the development of the Internet in the exporting country has a significant and negative effect on the share of exports by the top 5% or 25% of exporters, implying a larger share of SMEs. Moreover, we find that improved submarine cable infrastructure in the exporting country also leads to a lower share of exports by large exporters. These are in contrast to the estimated positive effect of telephone development in the exporting country, which may not disproportionately benefit indirect exporting via e-commerce platforms over direct exporting. Finally, we find an imperfect substitution relationship between e-commerce platforms and traditional intermediaries.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"57 ","pages":"Article 100940"},"PeriodicalIF":2.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.infoecopol.2021.100940","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42422293","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}

Using a dynamic panel model through system-GMM, the study finds that the demand price elasticity is higher for operators in developed countries. Controlling for cross-price elasticity with internet data prices reveals that voice communication is a substitute for internet data usage in developed countries. Another important finding is that, for operators in developing countries, the price elasticity decreases with market development level, whereas it increases for those in developed countries. Demand for mobile voice communication is thus more sensitive to price changes in the less penetrated markets in developing countries and the mature markets in developed countries. Furthermore, over time, price elasticity has decreased across operators in developing countries, highlighting the need for updating regulatory frameworks for the telecommunications sector to reflect the sector's various developments. In addition, when formulating regulatory and tax policies, some important economic factors, such as income level and domestic market characteristics, should be considered to avoid losses in consumer welfare. The high estimated price elasticities suggest that operators do not have an obvious interest in engaging in collusive behavior that would hinder competition. Moreover, since there is no differential effect due to operators’ positions or market shares, asymmetric regulation of the dominant operators should be avoided.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"57 ","pages":"Article 100939"},"PeriodicalIF":2.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.infoecopol.2021.100939","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48245298","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}

I conduct a survey of comic book readers to analyse the relationship between the pirate channels and the sales of comic books from the top American publishers. My data allows me to construct a time panel of comics readers and calculate the substitution rate between the paid and unpaid channels of comics acquisition. I find that piracy is negatively related to comics sales though mainly those of limited series. Moreover, for digital comics the relationship is observable only for a smaller group of readers with high valuations of digital formats. I also show that the digital comics – both paid and unpaid – are typically considered as inferior by the readers. With the price of digitally released new comics set at the same level as their print versions, this suggests that readers who do not want to pay the full price for print copies are more likely to use pirate sources than to switch to legal digital channels. Still, both paid and unpaid readership is associated with higher interest in other types of comics-based media such as movies or video games. This suggests that comics piracy might carry some indirect positive effects. As this aspect could improve the negotiating position of comic book authors it should be studied further.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"57 ","pages":"Article 100927"},"PeriodicalIF":2.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.infoecopol.2021.100927","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47842480","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}

However, the evidence on it is mixed and often misunderstood. Hence, this article carries out a systematic stocktaking of ICT tools’ impact on corruption, offering a nuanced and context-dependent assessment. The tools reviewed are digital public services, crowdsourcing platforms, whistleblowing tools, transparency portals, distributed ledger technology, and artificial intelligence. We scrutinise the evidence both on ICTs’ anticorruption effectiveness and misuse for corruption. Drawing on the commonalities across technologies, we find that ICT can support anti-corruption by impacting public scrutiny in numerous ways: enabling reporting on corruption, promoting transparency and accountability, facilitating citizen participation and government-citizen interactions. However, ICT can also provide new corruption opportunities through the dark web, cryptocurrencies, or the misuse of technologies such as centralised databases. The introduction of ICT tools does not automatically translate into anti-corruption outcomes; rather, impact hinges on the matching between ICT tools and the local context, including support for and skills in using technology.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"57 ","pages":"Article 100950"},"PeriodicalIF":2.8,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S016762452100038X/pdfft?md5=4e6723507cceccb492daf783d2f10171&pid=1-s2.0-S016762452100038X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46482646","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}
