1 Pasar Faktor Produksi

2 Pasar faktor produksi Faktor produksi adalah input yang digunakan dalam memproduksi barang dan jasa

3 Permintaan untuk faktor produksi adalah penurunan kurva permintaan.
Sebuah permintaan perusahaan untuk faktor produksi berasal dari keputusannya untuk memproduksi barang di pasar lain

4 Permintaan Tenaga Kerja
Pasar tenaga kerja, seperti pasar lain dalam perekonomian, yang diatur oleh kekuatan penawaran dan permintaan.

6 Kebanyakan jasa tenaga kerja, bukannya barang jadi siap untuk dinikmati oleh konsumen, adalah input ke dalam produksi barang-barang lainnya.

7 Fungsi Produksi dan Produk Marjinal Tenaga Kerja
Fungsi produksi menggambarkan hubungan antara kuantitas input yang digunakan dan kuantitas output yang diproduksi

10 Marginal Product Of Labor (MPL) adalah penambahan output yang dihasil dari penambahan satu unit tenaga kerja MPL = Q/L MPL = (Q2 – Q1)/(L2 – L1)

11 Diminishing Marginal Product of Labor
Ketika jumlah pekerja bertambah, produk marjinal tenaga kerja menurun. Jika pekerja semakin banyak, maka setiap pekerja memberikan tambahan kontribusi untuk produksi kurang dari yang sebelumnya. Fungsi produksi menjadi lebih datar karena jumlah pekerja meningkat. ini disebut produk marjinal menurun.

12 Penurunan marginal product mengacu kepada marginal input yang semakin menurun akibat penambahan tenaga kerja

14 The Value of the Marginal Product and the Demand for Labor
Nilai marginal produk adalah marginal produk input dikalikan dengan harga barang VMPL = MPL  P

15 The Value of the Marginal Product and the Demand for Labor
The value of the marginal product (also known as marginal revenue product) is measured in dollars. It diminishes as the number of workers rises because the market price of the good is constant.

16 The Value of the Marginal Product and the Demand for Labor
To maximize profit, the competitive, profit- maximizing firm hires workers up to the point where the value of the marginal product of labor equals the wage. VMPL = Wage

17 The Value of the Marginal Product and the Demand for Labor
The value-of-marginal-product curve is the labor demand curve for a competitive, profit- maximizing firm.

19 FYI—Input Demand and Output Supply
When a competitive firm hires labor up to the point at which the value of the marginal product equals the wage, it also produces up to the point at which the price equals the marginal cost.

20 What Causes the Labor Demand Curve to Shift?
Output Price Technological Change Supply of Other factors

21 THE SUPPLY OF LABOR The labor supply curve reflects how workers’ decisions about the labor-leisure tradeoff respond to changes in opportunity cost. An upward-sloping labor supply curve means that an increase in the wages induces workers to increase the quantity of labor they supply.

23 What Causes the Labor Supply Curve to Shift?
Changes in Tastes Changes in Alternative Opportunities Immigration

24 EQUILIBRIUM IN THE LABOR MARKET
The wage adjusts to balance the supply and demand for labor. The wage equals the value of the marginal product of labor.

26 EQUILIBRIUM IN THE LABOR MARKET
Labor supply and labor demand determine the equilibrium wage. Shifts in the supply or demand curve for labor cause the equilibrium wage to change.

28 An increase in the supply of labor :
Shifts in Labor Supply An increase in the supply of labor : Results in a surplus of labor. Puts downward pressure on wages. Makes it profitable for firms to hire more workers. Results in diminishing marginal product. Lowers the value of the marginal product. Gives a new equilibrium.

32 OTHER FACTORS OF PRODUCTION: LAND AND CAPITAL
Capital refers to the equipment and structures used to produce goods and services. The economy’s capital represents the accumulation of goods produced in the past that are being used in the present to produce new goods and services.

33 OTHER FACTORS OF PRODUCTION: LAND AND CAPITAL
Prices of Land and Capital The purchase price is what a person pays to own a factor of production indefinitely. The rental price is what a person pays to use a factor of production for a limited period of time.

34 Equilibrium in the Markets for Land and Capital
The rental price of land and the rental price of capital are determined by supply and demand. The firm increases the quantity hired until the value of the factor’s marginal product equals the factor’s price.

36 Equilibrium in the Markets for Land and Capital
Each factor’s rental price must equal the value of its marginal product. They each earn the value of their marginal contribution to the production process.

37 Linkages among the Factors of Production
Factors of production are used together. The marginal product of any one factor depends on the quantities of all factors that are available.

38 Linkages among the Factors of Production
A change in the supply of one factor alters the earnings of all the factors.

39 Linkages among the Factors of Production
A change in earnings of any factor can be found by analyzing the impact of the event on the value of the marginal product of that factor.
