To do so, we develop a model that considers the taxes and fees imposed directly or indirectly along the telecommunications value chain. Overall, we find strong evidence of a negative impact on investment from an increase in regulatory fees, profit taxes, and excise taxes. In addition, telecommunication service prices are affected by the fiscal regime, both directly -through taxation over services- and indirectly, through obligations imposed on operators that can ultimately have an impact on service prices. We also find some evidence of the effect of custom duties for equipment and smartphones on the decrease of investment on broadband network deployment and service adoption, respectively. On this basis, we simulate a fiscal-reform scenario, consisting in removing sector-specific contributions to eliminate inter-sectoral asymmetries, with results suggesting significant gains in investment, coverage, and adoption. Considering these findings, and the potential socioeconomic gains from increasing broadband adoption, we believe that governments pursuing the development of digital agendas should consider potential fiscal reforms to accelerate the development of the digital economy. That being said, considering the potential loses in tax collection, a careful trade-off analysis should be performed before determining the nature and the scope of the fiscal reforms to be introduced.</p></div>","PeriodicalId":47029,"journal":{"name":"Information Economics and Policy","volume":"62 ","pages":"Article 101016"},"PeriodicalIF":2.8,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49767449","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 first show that under a linear delay cost, if the delay cost of contents from each CP increases with its own traffic amount, the opposite is true, that is, the ISP prefers to give priority to a strong CP, whereas it prefers to give priority to a weak CP if the delay cost of contents from an unprioritized CP decreases with its traffic amount.

This paper uses a sample of German newspapers to investigate the conjecture that these modifications raised the incentives to publish quality news stories on the platform, focusing on the number and diversity of news story posts about substantive political issues. Using the newspapers’ print editions as a counterfactual, our results indicate an increase in the amount of substantive political news on Facebook by approximately 30%. This expansion occurred in a politically balanced way, except that the outlets disproportionately increased their Facebook coverage of the formerly underrepresented Linke (Left Party).

We investigate how integration between the ISP and a CP affects the ISP’s zero-rating choice and social welfare. Our findings are the following. First, the vertically integrated ISP might zero-rate the unaffiliated CP exclusively when the CPs’ profitability is not so low.
