Factors of Production

•Any resource used in a production process.

Factors of ProductionFactors of Production

These resources include:

• labor• land• capital• entrepreneurship

6

Factors of ProductionFactors of Production

Labor

•Labor is the physical and intellectual effort of people engaged in producing goods and services.

7

Factors of ProductionFactors of Production

Land

•Land is a natural-state resource such as real estate, grasses and forests, and metals and minerals.

8

Capital

•Capital includes the manufactured goods used to make and market other goods and services.

9

Human capital

•Human capital is the knowledge and skills acquired by labor, principally through education and training.

10

Entrepreneurship

•Enrepreneurship describes the people who alone assume the risks and uncertainties of a business.

11

Production Production PossibilitiesPossibilities

Production Possibilities

•The various combinations of goods that can be produced in an economy when it uses its available resources and technology efficiently.

12

EXHIBIT 1 PRODUCTION POSSIBILITIES FRONTIER

13

Exhibit 1: Production Exhibit 1: Production Possibilities FrontierPossibilities Frontier

1. What do points A, B, C, and D represent in Exhibit 1?

• They represent four consumption and capital goods possibilities when resources are used efficiently.

14

Exhibit 1: Production Exhibit 1: Production Possibilities FrontierPossibilities Frontier

2. What does the curve that passes through points A, B, C, and D represent?

• The curve represents all of the possible combinations of consumption goods and capital goods.

15

Exhibit 1: Production Exhibit 1: Production Possibilities FrontierPossibilities Frontier

3. Why does the curve have a balloon-like shape?

• The law of increasing costs accounts for the balloon-like shape of the production possibilities curve.

16

Exhibit 1: Production Exhibit 1: Production Possibilities FrontierPossibilities Frontier

4. If a production possibilities frontier was a downward-sloping straight line, would the law of increasing costs still hold?

• No.

17

Exhibit 1: Production Exhibit 1: Production Possibilities FrontierPossibilities Frontier

5. What would cause a production possibilities frontier to be a downward-sloping straight line?

• Resources are not specialized.

18

Production PossibilitiesProduction Possibilities

1. Is an economy operating on its production possibilities frontier if there is a high rate of unemployment?

• No. In this case the economy is operating inside its production possibilities frontier.

19

Production PossibilitiesProduction Possibilities

2. How can an economy produce a combination of goods outside its production possibilities frontier?

• If more resources become available, or if existing resources become more productive.

20

Evaluating Evaluating Production Production PossibilitiesPossibilities

1. Two things to keep in mind when evaluating production possibilities:

• Opportunity cost

• The law of increasing costs

21

Evaluating Evaluating Production Production PossibilitiesPossibilities

Opportunity Cost

•The quantity of other goods that must be given up to obtain a good.

22

Evaluating Evaluating Production Production PossibilitiesPossibilities

• Opportunity cost is typically subjective. One must rely on calculating expected gains and expected opportunity costs of choices made.

23

Evaluating Evaluating Production Production PossibilitiesPossibilities

Law of Increasing Costs

•The opportunity cost of producing a good increases as more of the good is produced.

24

Evaluating Evaluating Production Production PossibilitiesPossibilities

The law of increasing costs is based on two facts:

• Not all resources are suited to the production of all goods.

• The order of use of a resource in producing a good goes from the most productive resource unit to the least.

25

Evaluating Evaluating Production Production PossibilitiesPossibilitiesRelationship between opportunity

cost and law of increasing costs:

A) The opportunity cost of producing a good increases as more of a good is produced.

B) The negative slope of the production possibilities curve illustrates the fact that any increase in capital goods production must come at the cost of consumption goods production.

26

EXHIBIT 2 SHIFTS IN THE PRODUCTION POSSIBILITIES FRONTIER

27

Exhibit 2: Shifts in the Exhibit 2: Shifts in the Production Possibilities Production Possibilities

FrontierFrontier1. What will cause the production possibilities frontier to shift to the right?

• Investing in capital today expands the resource base of later periods, therefore allowing more capital and consumption goods in the future.

28

EXHIBIT 3 COMPARATIVE ECONOMIC GROWTH

29

Exhibit 3: Comparative Exhibit 3: Comparative Economic GrowthEconomic Growth

1. If an economy chooses to produce at point C, why does the production possibilities curve shift to the right?

A) The economy produced a mixture of consumption and capital goods.

30

Exhibit 3: Comparative Exhibit 3: Comparative Economic GrowthEconomic Growth

1. If an economy chooses to produce at point C, why does the production possibilities curve shift to the right?

B) Therefore, capital goods have been added to the resource base for future production.

31

Exhibit 3: Comparative Exhibit 3: Comparative Economic GrowthEconomic Growth

2. If an economy chooses to produce at point A on the Production Possibilities Curve, how will its economy compare to the first economy?

• Over time, the production gap between the two economies will widen.

32

Innovation

•Innovation is an idea that eventually takes the form of new, applied technology.

EXHIBIT 4 PRODUCTION POSSIBILITIES GENERATED BY SPEAR AND NET TECHNOLOGIES

34

Exhibit 4: Production Exhibit 4: Production Possibilities Generated by Possibilities Generated by

Spear and Net Spear and Net TechnologiesTechnologies

1. In Exhibit 4, why does the net technology yield greater production possibilities than the spear technology?

A) The “new” technology of the fishing net uses a different combination of land and labor.

35

Exhibit 4: Production Exhibit 4: Production Possibilities Generated by Possibilities Generated by

Spear and Net Spear and Net TechnologiesTechnologies

1. In Exhibit 4, why does the net technology yield greater production possibilities than the spear technology?B) The new combination makes it easier to move down along the production possibilities curve--producing even more capital goods--and shifting the curve further to the right.

36

Possibilities CurvePossibilities Curve

1. What could cause the production possibilities curve to shift inward in Exhibit 5?

• The destruction of capital goods and the disruption of people’s lives can cause the production possibilities curve to shift inward.

2. After shifting inward, what can explain the curve’s shift back to its original position and beyond?

• While capital goods can be destroyed, ideas are far more durable.

2. After shifting inward, what can explain the curve’s shift back to its original position and beyond?

What point reflects a currently unattainable production possibility?• Point E and all other points located outside of the production possibilities curve represent impossible production combinations. These points are unattainable with the resources and technology currently available.

47

Production Possibilities Production Possibilities and Economic and Economic StabilizationStabilization

Labor Specialization

• The division of labor into specialized activities that allow individuals to be more productive.

48

Production Possibilities Production Possibilities and Economic and Economic StabilizationStabilization

Benefits of Specialization:

A) Allows every entity--from individuals to nations--to do what they do best

B) Leads to greater productivity

49

Production Possibilities Production Possibilities and Economic and Economic StabilizationStabilization

Requirements of Specialization:

A) It requires an exchange system that allows each entity to exchange the goods it produces under specialization

50

Production Possibilities Production Possibilities and Economic and Economic StabilizationStabilization

Specialization is attractive because:

A) Those who specialize in what they do best will achieve greater material prosperity.

B) Everyone participating in the system produces more, exchanges more, and consumes more.

51

Specialization Specialization DecisionsDecisions

Two types of production advantages:

A) Absolute Advantage

B) Comparative Advantage

52

Absolute AdvantageAbsolute Advantage

Absolute Advantage

• A country’s ability to produce a good using fewer resources than the country with which it trades.
