3. Consumer Behavior: Utility & Indifference Curve
Consumer Behavior Theory
1. Cardinal Utility
Manfaat atau kenikmatan yang diperoleh konsumen dapat
dinyatakan secara kuantitatif
2. Ordinal Utility
Manfaat atau kenikmatan yang diperoleh konsumen tidak dapat
dikuantitatifkan

Pemaksimuman Utility (nilai guna)
Px = $2, Py = $1, M = $12.
Berapa kombinasi barang X dan Y yang memberikan kepuasan maksimum?
Berapa jumlah util secara keseluruhan?
Jawab:
Kombinasi: 3X & 6Y. Jumlah util = 16+14+12 + 11+10+9+8+7+6 = 93
Indifference Curve
1. Jika harga ice cream sandwiches $3, berapapendapatan Jason?
2. Berapa harga ice cream cones?3. Pada titik mana tercapai utilitas yang paling
tinggi?4. Berapa slope budget line (kemiringan garis
anggaran)?
Slope = ∆Y/ ∆X = -Qy0/Qx0 = -Px/Py
Penurunan Kurva Permintaan
GF’: M = $$6, Py = $1, Px = $2GF : M = $$6, Py = $1, Px = $1GF : M = $$6, Py = $1, Px = $0,6667
Price-Consumption Curve
An individual sets aside a certain amount of his income per month to spend on his two hobbies,
collecting T-shirt and collecting books. Given the information below, illustrate both the price-
consumption curve associated with changes in the price of T-shirt and the demand curve for books.
Kurva Engel
Dari gambar yang Sdr. buat berdasarkan Tabel 2, kemudian bila diketahui Py = Px = 1. Buatlah
budget line jika pendapatan konsumen: M1 = $$6, M2 = $10, dan M3 = $14.
Income-Consumption Curve
An individual consumes two goods, clothing and food. Given the information below,
illustrate both the income-consumption curve and the Engel curve for clothing and food.
