Which of the following statements regarding the learning curve and economies of scale is accurate? answers: just as diseconomies of scale are presumed to exist if a firm gets too large, there is a corresponding increase in costs in the learning-curve model as the cumulative volume of production grows. where diseconomies of scale are presumed to exist if a firm gets too large, there is no corresponding increase in costs in the learning-curve model as the cumulative volume of production grows. where diseconomies of scale are presumed to exist if a firm gets too small, there is no corresponding increase in costs in the learning-curve model as the cumulative volume of production grows. just as diseconomies of scale are presumed to exist if a firm gets too small, there is a corresponding increase in costs in the learning-curve model as the cumulative volume of production grows.

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?
