Q1: Since there are costs to the manufacturers to test and determine the star rating of each food product, would you be willing to pay more for having a health star rating at the front of the food package? Suppose the price of the box of cookies without the health star rating is $3, would you be willing to pay an additional 5% (or 15c) for the same product with the health star rating? | |||
Yes | No | ||
Q2: Given that you would pay an additional 5% (or 15c) for the same product with the health star rating, would you be willing to pay a little bit more, say 6% (or 18c)? | Q2: Given that you would not pay an additional 5% (or 15c) for the same product with the health star rating, would you be willing to pay a little bit less, say 4% (or 12c)? | ||
Yes | No | Yes | No |
Q3: How much would you be willing to pay for the additional health star rating? 7% (or 21c) 8% (or 24c) 9% (or 27c) Not willing to pay more | Q3: How much extra would you be willing to pay? 3% (or 9c) 2% (or 6c) 1% (or 3c) Not willing to pay more |
