Quyidagilar nimaga teng?

a) xususiy jamg’armalar;

b) davlat jamg’armalari;

v) tashqi dunyo jamg’armalari?

Yechish:

a) xususiy jamg’armalar quyidagi formula bo’yicha hisoblanadi:

S_p = (Y + TR+ N – T) – C

Y = C + I + G

Y = 1200 + 500 + 300 = 2000

S_p = (2000 + 200 + 100 – 400) – 1200 = 700

b) davlat jamg’armalari quyidagi formula bo’yicha hisoblanadi:

S_g = T – TR – N – G

S_g = 400 – 200 – 100 – 300 = – 300

v) tashqi dunyo jamg’armalari quyidagi formula bo’yicha hisoblanadi:

S_p = M – X, yoki S_r = –X_n

S_p = – X_n = (–100) = 100.

8-masala

Mamlakat iqtisodiyotidagi jamg’armalar (S) real foiz stavkasiga bog’liq (R):

S = 100 + 400R. Agar nominal foiz stavkasi 40% teng, narxlar oshishi sur’ati esa 30% ni tashkil etsa, u holda, jamg’armalar nimaga teng bo’ladi?

Yechish:

S = 100 + 400RÞS = 140Þ140 = 100 + 400R Þ 40 = 400RÞR = 40: 400 = 0,1Þ

S = 100 + 400RÞ100 + 400 x 0,1Þ S = 100 + 40 = 140.

Jamg’armalar 140 ga teng yoki nominal foiz stavkasi R_n =R_r – P, u holda real foiz stavkasi R_r = R_n – P Þ 40% – 30% = 10% Þ koef. 0,1 (10: 100) Þ

S = 100 + 400 x 0.1 = 100 + 40 = 140
