Do you believe that consumers consider a brand's supply chain ethics when they purchase apparel? do consumers bear any responsibility for the ways in which laborers in the apparel industry are treated? would you be willing to pay a premium for a brand that was transparent about their efforts to ensure that laborers are paid a fair wage and treated decently?

Four key marketing decision variables are price (p), advertising (a), transportation (t), and product quality (q). consumer demand (d) is influenced by these variables. the simplest model for describing demand in terms of these variables is: d = k – pp + aa + tt + qq where k, p, a, t, and q are constants. discuss the assumptions of this model. specifically, how does each variable affect demand? how do the variables influence each other? what limitations might this model have? how can it be improved?
