2 Copyright © 2004 South-Western/Thomson Learning Keyword Elastisitas Bagaimanakah dampak perubahan harga pada permintaan dan penawaran? Berapa besar dampak yang ditimbulkan?

3 Copyright © 2004 South-Western/Thomson Learning Anda seorang konsumen Buatlah list mengenai barang-barang apa yang tetap akan Anda beli meskipun harga barang tersebut naik 100% (Asumsi: pendapatan dari orang tua hanya 1.5 juta/bulan) Buatlah pula list barang-barang yang tidak akan Anda beli meskipun harga naik 100%.

5 Copyright © 2004 South-Western/Thomson Learning Faktor – Faktor yang Menentukan Elastisitas Permintaan Ketersediaan barang substitusi Kebutuhan vs Kemewahan Pengertian pasar Jangka waktu

6 Copyright © 2004 South-Western/Thomson Learning Menghitung Elastisitas Permintaan Penghitungan titik tengah

7 Copyright © 2004 South-Western/Thomson Learning Macam-Macam Elastisitas Permintaan Inelastis Kurang dari 1. Elastis Lebih dari satu. Elastisitas Unit Sama dengan 1
