Consider a firm that produces output using a Cobb–Douglas combination of capital and labor: Y = KαL1−α, 0 < α="">< 1.="" suppose="" that="" the="" firm’s="" price="" is="" fixed="" in="" the="" short="" run;="" thus="" it="" takes="" both="" the="" price="" of="" its="" product,="" p,="" and="" the="" quantity,="" y,="" as="" given.="" input="" markets="" are="" competitive;="" thus="" the="" firm="" takes="" the="" wage,="" w,="" and="" the="" rental="" price="" of="" capital,="">K, as given.
(a) What is the firm’s choice of L given P, Y, W, and K?
(b) Given this choice of L, what are profits as a function of P, Y, W, and K?
(c) Find the first-order condition for the profit-maximizing choice of K. Is the second-order condition satisfied?
(d) Solve the first-order condition in part (c) for K as a function of P, Y, W, and rK. How, if at all, do changes in each of these variables affect K?
