Data ownership,data collection and personalized pricing
Data ownership can either be considered as an indivisible monistic right or sepa-rated into ownership and usufruct,but the economic significance of data ownership and usufruct separation remains controversial.Digital enterprises'data-based services incentivize users to provide data,but also result in loss of privacy for users through personalized pricing.This paper constructs a monopoly firm model to explore the impact of data collection behavior and welfare under the definition of lack of usufruct and possession of usufruct when there is personalized pricing and privacy loss.The study finds that without usufruct,data collection will not occur if the privacy cost is high,but excessive data collection will occur if the privacy cost is low.When the collector has the initial usufruct and the user has ownership of the data,efficient data collec-tion can be achieved,improving user surplus and social welfare.Data ownership only affects the distribution of social welfare between the collector and user.Therefore,we should consider the right definition framework of data ownership and usufruct separation and discuss the ownership of data usufruct in different scenarios.When the privacy cost is low,data collectors should be granted usufruct,and users should be allowed to exercise ownership through the"deletion right"and other ways to improve social welfare and user surplus.When the cost of privacy is high or users underestimate the cost of privacy,the method of prohibiting data collection should be adopted to protect sensitive data,rather than confirming rights.
