Keseimbangan Pasar Ekonomi Materi

Keseimbangan Pasar ( ekuilibrium / E )
Rumus :
Qd = Qs atau Pd = Ps
Keterangan :
E = ekuilibrium
Qs = jumlah penawaran
Qd = jumlah permintaan
Pd = harga permintaan
Ps = harga penawaran
Contoh :
Fungsi permintaan Qd = 20 – P
Fungsi penawaran Qs = 5 +2P
Maka keseimbangan pasar yang baru adalah …..
Cara :
Qd = Qs
20 – P = 5 + 2P
15 = 3P
P = 15/3
P = 5
Q = 20-P
= 20-5
= 15
Jadi, keseimbangan pasar yang baru(Q,P) adalah 15,5
