Pada pasar persaingan sempurna fungsi permintaan dan penawaran adalah Qd = 250 - 3P dan Qs = - 150 + 2P Pertanyaan: a. Berapa harga dan kuantitas barang pada saat keseimbangan pasar b. Carilah harga dan kuantitas barang pada saat keseimbangan pasar yang baru ketika ada pajak Rp2/unit. c. Gambarkan kurva keseimbangan pasar tersebut. Jawab : Qd = 250 3P Qs = -150 + 2P a. P = ? Q = ? Qd = Qs Q = 250 3P 250 3P = -150 + 2P Q = 250 3(80) -3P 2P = -150 250 Q = 250 - 240 -5P = -400 Q = 10 P = -400 / -5 P = 80 b. P = ? Q = ? Jika ada pajak Rp. 2 / unit Qd = Qs Q = 250 3P 250 3P = -150 + 2(P - 2) Q = 250 3(80,8) 250 3P = -150 + 2P 4 Q = 250 242.4 -3P 2P = - 154 250 Q = 7.6 - 5P = -404 P = -404 / -5 P = 80,8
MATH6102 Business Mathematics-R3 c. Qd = 250 3P Qs = - 150 + 2P Mencari sumbu P dan Q pada fungsi permintaan (syarat P = 0) (syarat Q = 0) Q = 250 3P Q = 250 3P Q = 250 3(0) 0 = 250 3P Q = 250 (0 , 250) 3P = 250 P = 250/3 = 83.333 (83.333 , 0) Mencari sumbu P dan Q pada fungsi penawaran (syarat P = 0) (syarat Q = 0) Q = - 150 + 2P Q = -150 + 2P Q = -150 + 2(0) 0 = -150 + 2P Q = -150 (0 , -150) -2P = -150 P = -150/-2 = 75 (75 , 0)
MATH6102 Business Mathematics-R3 Setelah Pajak Rp. 2 Qs = - 150 + 2P Pajak : Rp. 2 Qs = -150 + 2(P 2) Qs = -150 + 2P 4 Qs = -150 4 + 2P Qs = -154 + 2P Mencari sumbu P dan Q pada fungsi penawaran ketika pajak Rp. 2 (syarat P = 0) (syarat Q = 0) Q = - 154 + 2P Q = -154 + 2P Q = -154 + 2(0) 0 = -154 + 2P Q = -154 (0 ,-154 ) -2P = -154 P = -154/-2 = (77 , 0)
