Our study will be based on an online experimental survey with respondents randomly assigned to different conditions. Our sample will include 4,000 Americans and 4,000 Canadians and it will be representative of the respective populations in terms of gender, race and ethnicity, age, and educational attainment. We will rely on the survey company Respondy for the recruitment.
A QSF file of the survey, reporting all conditions, is attached (not public), including the US version of the survey. The Canadian version is identical with just a few exceptions, to adapt it to the different institutional and geographical context (the questions about residence list Canadian provinces instead of US states, the questions about voting behavior in the most recent election concern the parliamentary elections in 2019 instead of the 2020 US presidential elections, and so on).
In addition to an initial set of screening questions where we establish quotas to make the sample representative in terms of age, educational attainment, gender, and race/ethnicity, the survey has five parts.
Part 1 of the survey will include general information as well as walk informed consent text.
Part 2 will include socio-demographic questions.
Part 3 represents the main randomized intervention. In this part, each respondent will evaluate the morality of and express their policy preference between two scenarios, one where the price of a product is fully determined by a company (or "the market"), and one in which a public authority imposes a price cap.
In part 4, we will ask participants about their opinions on the role of the markets and the government in an economy, and the extent to which they think the government should intervene to guarantee access to certain products. There will also be a trolley problem- like dilemma in this part.
In part 5, participants will answer questions about their time preferences, general trust in others, and pro-social preferences. With a probability of 1/4, respondents will also have the opportunity to donate $1 to a foundation that promotes free, unfettered markets (the Future of Freedom Foundation). More specifically, participants will gain $1 if they allow the researchers to donate $1 to this organization.
Note: Funding for the donation module of this study was provided by a University of Toronto’ Sandra Rotman Centre for Health Sector Strategy grant. The donation module was included purely for research purposes and it does not represent an endorsement of the organization by Johns Hopkins University or the University of Toronto, or by the authors of the study.
