production fune on för producing lentils: q = f(K, L) = A (aK/3 + BLV/3) where q is output per acre, K is capital, L is labour, and (A, a, B) are pa- rameters. Denote the wage rate by w, the price of capital by r, and the output price by p. a) Assume that the farmer is operating during a labour shortage, so that labour is fixed at L. Derive the short-run cost function.

Question
2. A farm has the following production function for producing lentils:
q = f(K, L) = A (ak/3 + BL'/3)
where q is output per acre, K is capital, L is labour, and (A, a, B) are pa-
rameters. Denote the wage rate by w, the price of capital by r, and the
output price by p.
a) Assume that the farmer is operating during a labour shortage, so that
labour is fixed at L. Derive the short-run cost function.
b) Describe the role of A in the production function. Calculate the ef-
fect of a marginal increase in A on the short-run cost function, and
explain how that result is related to the impact of A on production.
c) Using the short-run cost function derived in part a), setup the profit
maximization problem with output as the choice variable.
