Financial Incentives in Surveys of Healthcare Providers: Lotteries versus Guaranteed Payments

Principal Investigators: Halpern / Volpp 

Co-investigator:  Asch

This study will evaluate the relative efficacy of guaranteed payments (either up-front or conditional on response) vs. lotteries (in which respondents are entered into a random drawing for a larger reward) in increasing healthcare provider response to surveys. This study comprises 3 independent randomized trials of actuarially equivalent payments and lotteries.
