Acknowledgement We take this opportunity to express our deep sense of gratitude to our economics teacher Mr.Tote for spending his time and giving us his valuable guidance and for the interest he took in our project. At this point we would also like to place on our record our sincere effort of total commitment, dedication and hard work put by our each and every friends for their kind support and encouragement we got for this project. Last but not least we would like to thanks one and whole.

Definition of Economics

The study of how society chooses to allocate its scarce resources to the production of goods and services in order to satisfy unlimited wants

4

Microeconomics vs. Macroeconomics

• Macroeconomics

The branch of economics that studies decision-making for the economy as a whole

• MicroeconomicsThe branch of

economics that studies decision-making by a single individual, household, firm, industry, or level of government

5

What isCeteris Paribus? A Latin phrase that

means that while certain variables can

change, “all other things remain unchanged”

6

BASIC CONCEPTS:• Scarcity - the fundamental economic problem that human wants exceed the availability of time, goods, and resources. • Choice – Because individuals and society can never have everything they desire, they therefore are forced to make choices • Opportunity cost – the second best

alternative foregone for a chosen option.

7

1. Land Resource - any natural resource provided by nature

2. Labour - The mental and physical capacity of workers to produce goods and services

3. Capital - The physical plants, machinery, and equipment used to produce other goods(Financial capital - The money used to purchase capital)

4. Entrepreneurs - The creative ability of individuals to seek profits by combining resources to produce innovative products

Graphs provide a means to clearly show economic relationships in two-dimensional space. Economic analysis is often concerned with two variables confined to the upper right-hand (northeast) quadrant of the coordinate number system.

Graph

10

A shift in a curve occurs only when the ceteris paribus assumption is relaxed and a third variable not on either axis of the graph is allowed to change

11

Marginal Analysis- An examination of the effects of additions to or subtractions from a current situation

12

Production Possibilities Curve:

- A curve that shows the maximum combinations of two outputs that an economy can produce, given its available resources and technology

13

Technology:The body of knowledge and skills applied to how goods are produced

• A production possibilities curve illustrates an economy’s capacity to produce goods, subject to the constraint of scarcity. • The production possibilities curve is a graph of the maximum possible combinations of two outputs that can be produced in a given period of time, subject to three conditions:

Production Possibilities Curve

16

(1) All resources are fully employed

(2) The resource base is not allowed to vary during the time period.

(3) Technology, which is the body of knowledge applied to the production of goods, remains constant.

17

• Inefficient production occurs at any point inside the production possibilities curve. • All points along the curve are efficient points because each point represents a maximum output possibility. • All points outside the curve are unattainable due to scarcity of resources.

Points “inside”, “along” and “outside” the PPC

18

• PPC is usually concave to the origin because of the law of increasing opportunity costs that states that the opportunity cost increases as the production of an output expands. •The explanation for the law of increasing opportunity costs is that the suitability of resources declines sharply as greater amounts are transferred from producing one output to producing another output.

The shape of PPC

19

Economic Growth• The ability of an economy to

produce greater levels of output, represented by an outward shift of its production possibilities curve as a result of an increase in resources or an advance in technology

- The fundamental economic questions facing any economy are What, How, and For Whom to produce goods. - The WHAT question asks exactly which goods are to be produced and in what quantities. - The HOW question requires society to decide the resource mix used to produce goods. -The FOR WHOM problem concerns the division of output among society’s citizens.
