Dear Prof. Bliemer

Design
;alts = brandA_refurb, brandB_refurb, brandA_new, brandB_new
;rows = 20
;block = 2
;eff = (mnl,d)
;con
;model:
U(brandA_refurb) = ascA_refurb
+ condition*condition[0,1]
+ discount_linearA*discountreb[0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,0.95]*pricenewA[600]
+ discount_quadraticA*discountreb*discountreb*pricenewA /
U(brandB_refurb) = condition*condition
+ discount_linearB*discountreb*pricenewB[480]
+ discount_quadraticB*discountreb*discountreb*pricenewB /
U(brandA_new) = ascA_new
+ price*pricenewA/
U(brandB_new) = price*pricenewB

Thank you so much.
