1 Productivity and Growth Chapter 7

2 Growth is an increase in potential output Potential Output: the highest amount of output an economy can produce from the existing production function and the existing resources.

3 Real GDP per Person in Five Industrialized Countries,

4 The Remarkable Rise in Living Standards: The Record A Caveat Historical estimates are less precise Comparing economic output over a century cannot account for new goods and services

5 Queen Elizabeth owned silk stockings. The capitalist achievement does not typically consist in providing more silk stocking for queens but in bringing them within the reach of factory girls in return for steadily decreasing amounts of effort. --Joseph Schumpeter

6 Cost of Goods in Hours of Work Price in minutes of work Milk (½ gallon) Beef (1 pound) Eggs (1 dozen) Bread (1 pound) Chicken (3 lb. fryer) 1997 Beef (1 pound) Eggs (1 dozen) Bread (1 pound) Chicken (3 lb. fryer) Milk (½ gallon)

7 Today, the U.S. poverty level for a family of four is about $18,000. If we go back 100 years in U.S. history, and adjust for inflation, that $18,000 would put a family in the upper middle class.

8 Why “Small” Differences in Growth Rates Matter Compound Interest –Suppose: In 1800 $10 4% interest In 2000 the account is worth $25, $10 x (1.04) 200 = $25,507.50

9 Compounding Effect Rule of 72: the number of years it takes for a certain amount to double in value is equal to 72 divided by its annual rate of increase.

10 Why Nations Become Rich: The Crucial Role of Average Labor Productivity Real GDP Per Person

11 Real GDP per Person and Average Labor Productivity in the U.S.,

12 Share of the U.S. Population Employed,

13 Why Nations Become Rich: The Crucial Role of Average Labor Productivity Question –What determines a nation’s economic growth rate? In the long run, increases in output per person arise primarily from increases in average labor productivity.

14 The Determinants of Average Labor Productivity Human Capital –The talents, education, training, and skills of workers

15 The Determinants of Average Labor Productivity Diminishing Returns to Capital –If the amount of labor and other inputs employed is held constant, then the greater the amount of capital already in use, the less an additional unit of capital adds to production.

16 The Determinants of Average Labor Productivity Physical Capital –Public policy designed to stimulate growth should consider that: Increasing the amount of capital available to the workforce will tend to increase output and average labor productivity. The degree to which productivity can be increased by an expanding stock of capital is limited.

17 Average Labor Productivity and Capital per Worker in 15 Countries, 1990

18 The Determinants of Average Labor Productivity Land and Other Natural Resources –Generally, an abundance of natural resources increases the productivity of workers. –Resources can be obtained through international markets.

19 The Determinants of Average Labor Productivity Technology –New technologies are the single most important source of productivity improvement. –A new technology will expand the productivity in many sectors by stimulating greater specialization.

20 The Determinants of Average Labor Productivity Entrepreneurship and Management –Factors influencing entrepreneurship Taxation Regulation Social Customs

21 The Determinants of Average Labor Productivity Entrepreneurship and Management –Management: Influence productivity by implementing more efficient methods of production.

22 Sources of Growth 1.Capital accumulation. 2.Available resources. 3.Growth-compatible institutions. 4.Technological development. 5.Entrepreneurship.
