A firm has the following production function
Q = 2(XY) 0.5
Where, X is maize and Y is rice. The
cost of maize is K10 and the cost of rice Is K40. The firm has a
budget of K80 to spend on the two goods.
Formulate the firms’ optimization
problem.

1) Which of the following production functions exhibits constant
returns to scale?
A) q = KL
B) q = KL0.5
C) q = K + L
D) q = log(KL)
2) Why do firms tend to experience decreasing returns to scale at
high levels of output?
A) Firms face more problems with coordinating tasks and
communications among managers and workers at very high levels of
output.
B) Government tax policy tends to discourage large-scale production
operations.
C) Firms face fewer...
