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}

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}
