Answer to Problem 8.9P

After necessary observations, it can be proved that the short run total costs are equated to the given function;

  STC=1000+0.05q2

Explanation of Solution

As given, the production function is;

  q=K.L ,

In the short run, the K is fixed at 100, and this implies,

  q=10L

Based on the given values, the capital rents are $10 and wages are $5;

  STC=vK+wL=10×100+5L=1000+5L

On the other hand, the short run production function will be;

  q=10LSquaring on both the sides of the equation;q2=100LL=q2100Thus,STC=1000+5×q2100=1000+q220Thus, it can be derived as,STC=1000+0.05q2

Answer to Problem 8.9P

The quantity that could be produced is 200, and the number of labor hours required is 400.

Explanation of Solution

The function for the short run marginal cost is given as;

  SMC=0.1q

The price per unit is given as $20;

Now, since,

  P=MC20=0.1qq=200Thus, the quantity that could be produced is 200 units.Now, for labor hours, sinceL=q2100L= 2002100L=40000100L=400

Thus, the labor hours required is 400.

Answer to Problem 8.9P

After necessary calculations, it can be noticed that the quantity produced is 150 units and the labor hours required for this produce is 225.

Explanation of Solution

It is given that the price per unit during the recession is reduced to $15,

Now, using the relationship,

  P=MCImplies,15=0.1qq=150Thus, the quantity produced can be 150.Now, the relation becomes;L=q2100L= (150)2100L=22500100L=225

Answer to Problem 8.9P

After necessary calculations and observations, it can be concluded that the current proposition is better than the previous proposition in part C.

Explanation of Solution

It is given that during the 1 week of recession, the firm incurs a loss of $1 for every reduction in the workforce.

This implies when L reduced from 400 to 225, the cost the firm incur will be 175.

This means, when q=150, the profit making will be:

  π=TRTC=150×15(1000+1125)=22502125=125

Now, if there is a cost of 175, there will be a loss 50.

In the case of 400 labors, there will be no cost and the profit will be:

  π=TRTC=15×200(1000+2000)=30003000=0

Thus, it can be concluded that the current proposed case is better than the previous case proposed in part C.
