Publication Preview Effects of Freemium Strategy in the Mobile App Market: An Empirical Study of Google Play Journal of Management Information Systems

Charles Zhechao Liu, Yoris A. Au, Hoon Seok Choi

2015

This paper examines the effect of the freemium strategy on Google Play, an online marketplace for Android mobile applications. By analyzing a large panel data set consisting of 711 ranked mobile apps, we found that the freemium strategy is positively associated with increased sales of the paid mobile apps. Positive trial experience as represented by high review rating of the free version of a mobile app leads to higher sales of its paid version, whereas high visibility of the free version of a mobile app as represented by its product rank does not have a significant impact on the sales of its paid version. This finding suggests that although offering a free trial version is a viable way to improve the visibility of a mobile app, offering a quality free app is more important in boosting sales of the paid app. Moreover, we found that the impact of review rating is reduced when the free version is offered, or when the mobile app is a hedonic app, because consumers have the ability to experience the app themselves before purchase. These findings extend understanding of the freemium business model to include a market characterized by simultaneous intramarket competition for both the freemium and paid products and demonstrate how such dynamics may influence sales of the paid products.

An empirical study of the freemium strategy for mobile apps: Evidence from the google play market An empirical study of the freemium strategy for mobile apps: Evidence from the google play market

Thirty Third International Conference on Information Systems

2012

This paper examines the effect of the freemium strategy on Google Play, an online marketplace for Android mobile apps. By analyzing a large panel dataset consisting of 1,597 ranked mobile apps, we found that the freemium strategy is positively associated with increased sales volume and revenue of the paid apps. Higher sales rank and review rating of the free version of a mobile app both lead to higher sales rank of its paid version. However, only higher review rating of the free app contributes to higher revenue from the paid version, suggesting that although offering a free version is a viable way to improve the visibility of a mobile app, revenue is largely determined by product quality, not product visibility. Moreover, we found that the impact of review rating is not significant when the free version is offered, or when the mobile app is a hedonic app.

Assessing Researcher Publication Productivity in the Leading Information Systems Journals: A 2005-2009 Update. Communications of the Association for Information Systems

Jan Guynes Clark, Yoris A Au, Diane B Walz, John Warren

2011

This study is an update of a previous scientometric study that examined the leading Information Systems (IS)
researchers, their university affiliations, and the universities that supply them. We provide geographical comparisons of researcher affiliations for the AIS regions and for North American versus global institutions, along with a comparison of prior and current results. Our analysis shows that coauthorship is increasing in the top three IS journals and that most of the leading researchers continue to affiliate with institutions in North America. However, the proportion of publications from North American researchers in the top three journals has decreased slightly over time This research contributes to the scientometric literature by identifying a more broad and inclusive set of leading IS publications and by providing benchmarks for the productivity of IS scholars. These results can be valuable for deans and department chairs making tenure and promotion decisions. Prospective students and faculty can use these results to identify universities which match their personal research goals. This study also helps to define and expand the boundaries of the IS discipline due to its use of a broader set of leading journals.

The economics of mobile payments: Understanding stakeholder issues for an emerging financial technology application Electronic Commerce Research and Applications

Yoris A Au, Robert J Kauffman

2008

Economic theory provides a unique vantage point from which to examine issues with respect to emerging technologies, where standards and adoption, business process changes and implementation outcomes, information security, investments and business value, and industry impact require care and consideration on the part of senior management strategists and financial services leaders. In this article, we examine a new technology application which is coming into its own around the world, in association with the revolution in wireless connectivity: mobile payments. Although there are likely to be nuances and surprises with this technology application, we caution the reader to recognize that many of the same economic forces will be at work as were with other financial services and related technology applications in the past. We apply a robust evaluative framework that permits identification of the relevant stakeholders and applicable theory in the analysis of consumer, firm, business process, market, industrial and social issues. Our findings are intended to guide senior managers in dealing with the economic aspects of mobile payments, and to help identify some important directions for the research.
