Abstract
With the penetration of technology into new markets, there are a number of questions around data privacy that have been insufficiently studied. Moreover, many of the core issues in data privacy are behavioral in nature, such as the intention-action gap and hyperbolic discounting manifested by consumers. We will study two key aspects of data privacy behaviors: 1) How to make consumers more privacy-conscious through different dissemination techniques of privacy policy agreements and streamlining the consent process to make it more effective and 2) Privacy as a business advantage for industry through exploration of privacy disclosure, control over data, and ways of sharing data. This study incorporates an experimental approach. We test people’s revealed preferences for sharing data through lab games programmed on computers and understand their stated preferences through vignettes and survey questions. Our results will be used to demonstrate methods that make users engage more with consent and privacy policies and allow businesses to benefit from more aware consumers and improved data sharing practices.

Experimental Details
Interventions
Intervention(s)
The interventions of this study consisted of visual cues or primes, which accompanied a standard privacy policy. These primes varied in the number of units and amount of visual and written content they contained. All the interventions appeared at the same point during the experiment for all respondents. The interventions can be grouped into five main categories: star ratings, usage case, costly signalling, summary infographic, and cool-down period.

Primary Outcomes
Primary Outcomes (end points)
Willingness to part with sensitive information, Willingness to share information for personalisation
Primary Outcomes (explanation)
Willingness to part with sensitive information: This is constructed from 30 yes-or-no questions that vary in sensitivity. The number of "Yes" responses will be added to create a count ranging from 0 to 30, which will be used as a proxy for willingness to part with sensitive information.
Willingness to share information for personalisation: This outcome will consist of a count from 0 to 10. Respondents will be asked if they are willing to answer a certain question and then will be asked the question. The number of questions they say they will answer will be calibrated into the count and used as a proxy for willingness to share information for personalisation.

Manipulation checks: These consist of a set of questions about the privacy policy and check whether respondents remember and have understood the privacy policy. We will be adding these up to create a variable that captures the number of correct responses.

Experimental Design
Experimental Design
This study will be conducted as an experimental randomised control trial with an online sample. Respondents will be randomly allocated to one of twelve treatment groups. They will be presented with the same privacy policy, which is followed by an intervention. The intervention will be based on the group they are assigned. They will then play some lab games and answer a series of questions. After this, they will complete the manipulation checks and finish with the experiment.
