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)

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

Paradox Nilai

Mengapa air yang sangat penting bagi keidupan harganya lebih murah dari berlian?

Consumers’ Surplus

Indifference Curve = Kurva kepuasan sama

Indifference Curve

Indiffference Curve

Gambarlah tiga kurva indifference curve (IC I, IC II dan IC III).

Budget Line

Keseimbangan Konsumen

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.

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.
