This paper explores the question of why some digital products are not in the subscription service of the sales platform. To address this problem, we develop an analytical model to examine two strategies of the firm. One is that the firm does not add the new product into the subscription service, the other is that the firm adds the new product into the subscription service. By comparing the profits under two sets, we find the condition under which the firm should add the new digital product into the subscription service. The results show that if the percentage of existing subscribers is below a certain threshold, and the subscription price is over a certain threshold, it is better for the firm to add the new product into the subscription service. We also analyze how the main variables affect the firm\u2019s profit and the piracy rate. Our research provides useful insights for firms in choosing pricing schemes for the newly released product and offers advice for policymakers on controlling the piracy rate of digital products industry.<\/jats:p>","DOI":"10.3390\/jtaer19020048","type":"journal-article","created":{"date-parts":[[2024,4,22]],"date-time":"2024-04-22T12:38:41Z","timestamp":1713789521000},"page":"921-941","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Whether to Add a Digital Product into Subscription Service?"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2900-0904","authenticated-orcid":false,"given":"Linlan","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Business, Hubei University, 368 Youyi Road, Wuhan 430062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yu","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Business, Hubei University, 368 Youyi Road, Wuhan 430062, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"119","DOI":"10.1287\/mksc.21.2.119.147","article-title":"Optimal Pricing of New Subscription Services: Analysis of a Market Experiment","volume":"21","author":"Danaher","year":"2002","journal-title":"Mark.
