Previous research on high-frequency preference variation has been limited partly due to a lack of appropriate data sources. In this study, we propose to address this limitation by conducting a survey that elicits individual preferences over risk and time repeated over the course of several weeks.","","","",2019-06-06,2020-09-06,"",Refer to pre-analysis plan,"","","",Refer to pre-analysis plan,"",Randomization was done in MS Excel.,individual,252,252,"63 @ 8am, 63 @ noon, 63 @ 4pm, 63 @ 8pm","","Name: USC University Park Institutional Review Board Approval_number: UP-19-00325 Approval_date: 2019-05-29 ",Private,,,,"",,"","",,"",,"","",""
