The Supply and Demand for Data Privacy: Evidence from Mobile Apps

 


 

Date: 11 Jan 2023 (Wed)


Time: 10am – 11:10am (Hong Kong Time, UTC+8)


Abstract: This paper investigates how consumers and investors react to the standardized disclosure of data privacy practices. Since December 2020, Apple has required all apps to disclose their data collection practices by filling out privacy "nutrition" labels that are standardized and easy-to-read. The authors web-scrape these privacy labels and first document several stylized facts regarding the supply of privacy. Second, augmenting privacy labels with weekly app downloads and revenues, the authors examine how this disclosure affects consumer behavior. The authors exploit the staggered release of privacy labels and use the nonexposed Android version of each app to construct the counterfactual. After privacy label release, an average iOS app experiences a 14% (15%) drop in weekly downloads (revenues) when compared to its Android counterpart, with an even stronger effect for more privacy-invasive and substitutable apps. Consumers in the US, UK, and France respond more negatively, suggesting that they are most averse to data collection. Moreover, the authors observe adverse stock market reactions, especially among firms that harvest more data, corroborating the findings on product markets. Their findings highlight data as a key asset for firms in the digital era.

About the Webinar

Artificial Intelligence (AI), Big Data, multilevel neural nets, the Internet of Things (IoT) and other digital technologies are transforming the world. They are strengthening innovation and productivity and innovation by rendering the future more predictable and reshaping individual, business, social, and government behavior. Asia leads the world in some of these endeavors, e.g., digital platforms. The OECD lists 40% of big new digital technologies as Asian. Almost half of global digital platform business-to-consumer revenues are Asian, versus only 22% from the U.S. and 12% from the Eurozone. Profound new policy challenges arising, in consequence, include: shifting skills demanded in labor markets and “digital divide” inequality, (ii) AI expanding financial inclusion or encoding inequality, expanding or obscuring accountability, increasing transparency or obscuring amoral decision-making, and (iii) digital privacy, unsanctionable on-line libel, misinformation, manipulation, and propaganda. The ABFER, therefore, plans a monthly e-seminar series spotlighting important new research, particularly the Asia-pacific related, into these issues and providing “state-of-the-art” overviews by prominent scholars. We hope policy makers and practitioners will find the e-seminars helpful and will alert researchers to issues needing attention.
