Abstract
In this experiment, we develop a non-deceptive methodology to estimate the willingness-to-pay for products whose technology is already functional, but that are not on the market yet.
We apply this methodology for a specific category of cultured meat, i.e., foie gras.
We elicit French participants' willingness-to-pay for this new product and correlate it with standard demographic variables and attitudes towards meat.
We further elicit participants' beliefs about the probability that they actually receive the cultured-meat product. We derive the appropriate correction of beliefs when participants report their beliefs under uncertainty about the availability of the product.

Experimental Details
Interventions
Intervention(s)
Participants are first exposed to a pre-experimental questionnaire at least one week before the actual experiment. We elicit: their diet, their pro-meat justification, their concerns about dietary choices, neophobia.

Later, participants do the experiment. In the experiment, they are introduced with a cultured meat product (Foie Gras) developed by a French start-up. This product is not on the market yet, and cannot be delivered to participants.

Participants are told that it has been determined prior to the experiment whether they will actually receive the product depending on availability. Participants receive the money that they can use to buy the product (if available). We further elicit: their perception of the product, their perception of farmed foie gras, their pro-meat justification, their beliefs about the availability of the product (using quadratic scoring rule), their risk aversion, and some demographics (age, gender, countryside-raised, political self-placement).

Primary Outcomes
Primary Outcomes (end points)
Willingness-to-pay (WTP) for the cultured meat product.
The beliefs about the availability of the product.
Primary Outcomes (explanation)
The elicitation of the WTP is made using a Becker–DeGroot–Marschak method (BDM) with a list of prices from 0€ up to 8€ for 100g of cultured meat. The WTP is either equal zero if the respondent reports "I don't buy" for all prices. It lies in the interval between the two prices that define the switching point if there is one switching point. It is above 8€ if the respondent reports "I buy" for all list of prices.
We will keep only well-behaved answers (i.e., monotonic decrease in utility with the price).

The beliefs about the availability of the product will be incentivized with a quadratic scoring rule. We will primarily examine if the probability that the product is delivered is strictly greater than zero, and consider appropriate correction for stakes and risk aversion.
Secondary Outcomes
Secondary Outcomes (end points)
Pro-meat justifications (PMJ), Animal-based consumption (ABC), Neophobia, risk aversion.
Secondary Outcomes (explanation)
PMJ: sum of items.
ABC: Principal component analysis on red meat, white meat, fish, eggs, diary products.
Neophobia: score defined by Pliner 1992, Appetite.
Risk aversion: See Holt and Laury (AER, 2002).
Experimental Design
Experimental Design
Participants will fulfill the pre-experimental questionnaire (see materials) and then the experiment at least one week after (see materials).
