I keep ascA_new and priceA=priceB=price. Could you please give me your opinion?

Dear Prof. Bliemer

For different survey, I would like to generate choice sets with different new product prices.
Could you please take a look at the following syntax.

Design
;alts = brandA_refurb, brandB_refurb, brandA_new, brandB_new
;rows = 20

Dear Prof. Bliemer

I do not understand the following part

U(brandA_new) = ascA_new
price*pricenew/

Should it be "ascA_new+price*pricenew/"?

So the parameters to be estimated are:
ascA_refurb
condition
discount_linearA
discount_quadraticA
discount_linearB
discount_quadraticB
ascA_new
Is ...

Dear Prof. Bliemer

Thank you so much for your willingness to help and let me learn from you. I am using model estimation
a*discount + b*discount^2
to estimate a quadratic relationship.
