Suppose a farmer is using two inputs, labour (L) and capital (K), to produce the same amount
of wheat (i.e. 100 tons of wheat). The production function is given by L0.5 + K0.33
a) Discuss any three (3) characteristics of the model described above.
b) Explain how it would be possible for a farmer to use L and K to produce the same
amount of wheat.
c) Derive MPP of L and MPP of K.
d) Determine the marginal rate of substitution of L and K.
Prove, algebraically, that the Marginal Rate of Substitution (MRS) between L and Kis
given by MRSLK = -MPPL/MPPK.
f) Explain why the total change in wheat output along the isoquant curve is equal to zero.

Expert Solution
Step 1

Given 

Production function:  Y=L0.5+K0.33     .... (1)

We have to show that the marginal rate of substitution MRSLK=-MPPLMPPK

The marginal rate of substitution if the slope of the isoquant curve.  

MRSLK=dKdL      ..... (2)
