Chapter 25: Production and Growth

Incomes and Growth Around the World

Poor countries are not poor forever

poor can faster-growing than rich countries

Productivity is important for a country's living

measured by output / labor unit (Y/L).

Y = real GDP = quantity of output produced

L = quantity of labor

↑ machines and equipment per worker (K/L) => ↑ productivity (Y/L).

↑ education and skills per worker (H/L) => ↑ productivity (Y/L).

↑ natural resources per worker (N/L) => ↑ productivity (Y/L)

but countries can be rich without many natural resources.

Technological knowledge improves productivity by finding better ways to produce goods and services.

  • Technological knowledge is society's understanding of production
  • human capital is individuals' learned skills
  • both ↑ productivity.

The Production Function

Y = A*F(L, K, H, N)

2Y = A*F(2L, 2K, 2H, 2N)

F gồm L K H N, cả LKHN tăng 2 thì Y tăng 2
A giữ nguyên

A: the level of technology,
hằng số ko đổi

F: input

Y: output

public policy can affect growth in productivity and living standards ?

Saving and Investment

increasing K, which requires investment.

growth in productivity and living standards

The Production Function
(biểu đồ hàm sản xuất)

Ox: K/L (Capital per worker)
Oy: Y/L (output / labor)

càng lên cao càng giảm dần

The catch-up effect

poor countries tend to grow more rapidly than rich ones

requires both countries to have the same technology
