Answer to Problem 6NP

If there is a rise in the demand for a dashboard GPS which follows the prices of automobiles can result in complement decrease.

Explanation of Solution

  Y=A(5N0.0025N2)

  MPN=5A0.005AN

  Cd=300+0.8(YT)200rId=258.5250r

  A(f1N12f2N2)=A(5N0.0025N2)=A(5N 0.0025 0.5N2)=A(5N12×0.005N2)

  NS=n0+nw(1t)wn0+nw(1t)w=55+10(1t)w

  Cd=c0+cY(YT)Crrc0+cY(YT)crr=300+0.8(YT)200r

  T=t0+tY=20+0.25Y

  Id=i0irr=258.5250r

  MdP=l0+lyYlr(r+πe)l0+lyYlr(r+πe)=0.5Y250(r+πe)

After choosing the profit maximizing quantity, the firm will charge a price of The firm will receive $ in revenue at the profit-maximizing quantity. The total cost of production for this profit-maximizing quantity is S The maximum profit the firm can earn in this situation is $ per unit for this output. How will the situation change over time? Profits will attract rival firms into the market until the profit-maximizing price falls to the level of per-unit cost. ◇ Losses will induce firms to leave this market until the profit maximizing price falls to zero. The market will adjust until the price charged by this firm no longer exceeds marginal cost at the profit-maximizing quantity. This market is already in long-run equilibrium, and will not…
