Menghitung Fungsi Pendapatan, Tabungan, dan Konsumsi

Fungsi Pendapatan
Komponen pendukung :
Y -> pendapatan
C -> konsumsi
S -> tabungan
I -> investasi

1. Fungsi Pendapatan
Y = C + S

2. Jika tabungan (saving = S) digunakan seluruhnya untuk investasi, maka S=1, sehingga :
Y = C + 1

3. Fungsi konsumsi
C = a + bY
Biar mudah inget rumusnya, pake aja singkatan : C a b y

4. Fungsi tabungan
S = -a + (1-b)Y
Biar mudah inget rumusnya, pake aja singkatan : S a i b y
