  2. Predstavme si, že v monopolisticky konkurenčnom trhu s TV sú 2 krajiny. Ročný predaj TV domácej krajiny je 750 000 jednotiek a zahraničnej krajiny 4 320 000 jednotiek. Obe krajiny majú rovnaké náklady produkcie. Hodnota fixných nákladov je 600 000 000 a hraničných nákladov na výrobu extra jednotky je 3 000. Za predpokladu, že krajiny medzi sebou neobchodujú, zistite počet firiem na trhu, output každej firmy, priemerné náklady a cenu 1 jednotky TV pre domácu aj zahraničnú krajinu. Aké zmeny môžeme pozorovať na trhu, kde by dané krajiny medzi sebou začali obchodovať? Znázornite graficky.

  3. F = 600 000 000 c = 3000 Sh=750 000 Sf= 4 320 000 b = 1/20 000 n = ? Q = ? P = ? AC = ? Q = S x [1/n – b x (P –P)] P = c + Q (S x b) = c + 1/(b x n) AC = F/Q + c = n x F/S + c

  4. Predpokladáme, že..... P = P Q = S/n AC = P

  5. Home Market before Trade AC = P F/Q + c = c + 1/(b x n) 600 000 000 / Q = 1 / (n/ 20 000) 600 000 000 / Q = 20 000 / n 600 000 000 x n / 20 000 = Q Q = 30 000 x n Q = S/n 30 000 x n =750 000 / n n2 = 750 000 / 30 000 n2 = 25 n = 5 Q = S/n Q= 750 000 / 5 Q = 150 000

  6. Výpočet AC a P AC = F/Q + c AC = 600 000 000 / 150 000 + 3000 AC = 4 000 + 3 000 AC = 7 000 P = c + 1/ (b x n) P = 3 000 + 1 / (1/20 000 x 5) P = 3 000 + 4 0000 P = 7 000 AC = P

  7. Foreign Market befire Trade AC = P F/Q + c = c + 1/(b x n) 600 000 000 / Q = 1 / (n/ 20 000) 600 000 000 / Q = 20 000 / n 600 000 000 x n / 20 000 = Q Q = 30 000 x n Q = S/n 30 000 x n =4 320 000 / n n2 = 4 320 000 / 30 000 n2 = 144 n = 12 Q = S/n Q= 4 320 000 / 12 Q = 360 000

  8. Výpočet AC a P AC = F/Q + c AC = 600 000 000 / 360 000+ 3000 AC = 1 666,7 + 3 000 AC = 4 666,7 P = c + 1/ (b x n) P = 3 000 + 1 / (1/20 000 x 12) P = 3 000 + 1 666,7 P = 4 666,7 AC = P

  9. Integrated Market after Trade AC = P F/Q + c = c + 1/(b x n) 600 000 000 / Q = 1 / (n/ 20 000) 600 000 000 / Q = 20 000 / n 600 000 000 x n / 20 000 = Q Q = 30 000 x n Q = S/n 30 000 x n = 5 070 000 / n n2 = 5 070 000 / 30 000 n2 = 169 n = 13 Q = S/n Q= 5 070 000 / 13 Q =390 000

  10. Výpočet AC a P AC = F/Q + c AC = 600 000 000 / 390 000+ 3000 AC = 1 538,46 + 3 000 AC=4 538,46 P = c + 1/ (b x n) P = 3 000 + 1 / (1/20 000 x 12) P = 3 000 + 1 538, 46 P = 4 538,46 AC = P
