1 STRUKTUR PASAR Market Structure: Perfect Competition, Monopoly and Monopolistic Competition

2 Market Structure Struktur Pasar (Market Structure) adalah lingkungan yang menggmbarkan tingkat persaingan pembeli danpenjual dari suatu produk. Struktur Pasar dikelompokkan menjadi empat kelompok utama, yaitu : Persaingan Sempurna (Perfect Competition). Monopoli. Persaingan Monopolistik (Monopolistic Competition). Oligopoli Imperfect Competition Pengelompokan pasar ini didasarkan pada karakteristik demand yang dihadapi seorang produsen, kekuatan produsen serta jumlah prodsen.

3 Market Structure Perfect Competition Monopolistic Competition Oligopoly Monopoly More Competitive Less Competitive

4 Beberapa Hal yang Harus Diketahui oleh Manajer Bisnis 1.Bentuk struktur perusahaan 2.Pola permintaan produk yang dijual 3.Pola biaya produksi 4.Strategi pengendalian input (penggunaan input) dan pengendalian output (keputusan jumlah output yang harus diproduksi) 5.Strategi penetapan harga produk untuk mencapai tujuan peruasahaan (memperluas pasar atau memaksimumkan keuntungan)

5 Perfect Competition Many buyers and sellers Buyers and sellers are price takers Product is homogeneous Perfect mobility of resources Economic agents have perfect knowledge Example: Stock Market

6 Monopolistic Competition Many sellers and buyers Differentiated product Perfect mobility of resources Example: Fast-food outlets

7 Oligopoly Few sellers and many buyers Product may be homogeneous or differentiated Barriers to resource mobility Example: Automobile manufacturers

8 Monopoly Single seller and many buyers No close substitutes for product Significant barriers to resource mobility –Control of an essential input –Patents or copyrights –Economies of scale: Natural monopoly –Government franchise: Post office

9 Perfect Competition: Price Determination

10

11 Perfect Competition: Short-Run Equilibrium Firm’s Demand Curve = Market Price = Marginal Revenue Firm’s Supply Curve = Marginal Cost where Marginal Cost > Average Variable Cost

12 Firm equilbrium tercapai ketika perusahaan mencapai tingkat output yang paling menguntungkan, yaitu ketika MR=MC Perfect Competition: Short-Run Equilibrium

13

14

15 Perfect Competition: Long-Run Equilibrium Price = Marginal Cost = Average Total Cost Quantity is set by the firm so that short-run: At the same quantity, long-run: Price = Marginal Cost = Average Cost Economic Profit = 0

16 Perfect Competition: Long-Run Equilibrium

17 Strategi Pengendalian Output Dalam Pasar Persaingan Sempurna untuk Memaksimumkan Keuntungan Informasi Harga Produk (P) Informasi AVC dan MC Apakah P>AVCmin Tidak Keputusan Manajer TIDAK BERPRODUKSI Ya Keputusan Manajer Berproduksi pada MR=MC Keuntungan π = TR – TC.

18 Competition in the Global Economy Domestic Supply Domestic Demand World Supply

19 Competition in the Global Economy Foreign Exchange Rate –Price of a foreign currency in terms of the domestic currency Depreciation of the Domestic Currency –Increase in the price of a foreign currency relative to the domestic currency Appreciation of the Domestic Currency –Decrease in the price of a foreign currency relative to the domestic currency

20 Competition in the Global Economy Demand for Euros Supply of Euros R = Exchange Rate = Dollar Price of Euros /€ € € €

21 Ciri-ciri Pasar Monopoli: Pasar monopoli adalah industri/pasar satu perusahaan (Single seller and many buyers). Tidak mempunyai barang pengganti yang mirip (No close substitutes for product). Perusahaan lain tidak terdapat kemungkinan untuk masuk ke dalam industri (Significant barriers to resource mobility). Dapat menguasai penentuan harga (price setter) Promosi iklan kurang diperlukan Monopoly

22 Single seller that produces a product with no close substitutes Sources of Monopoly –Control of an essential input to a product De Beers Company (Perusahaan Permata di Afrika Selatan) Standar Oil Company (Perusahaan Minyak di Amerika Serikat) Aluminium Company of America-Alcoa –Patents or copyrights Xerox (mesin foto copy) Polaroid (instant camera) –Economies of scale: Natural monopoly –Government franchise: Post office

23 Monopoly Short-Run Equilibrium Demand curve for the firm is the market demand curve Price setter Market power Firm produces a quantity (Q*) where marginal revenue (MR) is equal to marginal cost (MC) Exception: Q* = 0 if average variable cost (AVC) is above the demand curve at all levels of output

24 Monopoly Short-Run Equilibrium Q* = 500 P* = $11

25 Monopoly Short-Run Equilibrium

28 Monopoly Long-Run Equilibrium Q* = 700 P* = $9

29 Monopolistic Competition Many sellers of differentiated (similar but not identical) products Limited monopoly power Downward-sloping demand curve Increase in market share by competitors causes decrease in demand for the firm’s product

30 Monopolistic Competition Short-Run Equilibrium

31 Monopolistic Competition Long-Run Equilibrium Profit = 0

32 Monopolistic Competition Long-Run Equilibrium Cost without selling expenses Cost with selling expenses
