Q1: Discuss the central problems of an economy.
Ans: Every economy faces the problem of scarcity of resources in relation to unlimited wants. Because of this, every society has to make choices regarding the use of its limited resources. These are known as the central problems of an economy:
1. What is produced and in what quantities?
Every society must decide which goods and services to produce and in what quantities. For example, it has to choose between producing more consumer goods or capital goods, or between agricultural and industrial goods.
2. How are these goods produced?
This problem refers to the choice of technique of production. A society has to decide whether to use labour-intensive methods or capital-intensive methods, depending on the availability of resources and cost considerations.
3. For whom are these goods produced?
This problem relates to the distribution of goods and services among individuals in the economy. It involves deciding who will get how much of the total output, i.e., how income and output are shared among people.
Thus, the central problems of an economy arise due to scarcity of resources and involve the allocation and distribution of resources efficiently.

Q2: What do you mean by the production possibilities of an economy?
Ans: The production possibilities of an economy are the different combinations of goods and services that can be produced with the available resources and technology when resources are used efficiently. These combinations show the trade-offs a society faces: producing more of one good requires producing less of another. The concept also helps to illustrate opportunity cost - the value of the next best alternative foregone when a choice is made.
Q3: What is a production possibility frontier?
Ans: The production possibility frontier (PPF), or production possibility curve (PPC), is a curve that shows various efficient combinations of two goods that an economy can produce with a given set of resources and technology.
Points on the curve (for example, points on curve AE in the figure) represent full and efficient use of resources. Points inside the curve (like F) indicate inefficiency or under-utilisation of resources. Points outside the curve (like Z) are unattainable with current resources and technology.
The PPF is typically downward sloping because increasing production of one good requires sacrificing some production of the other. The PPF is concave from the origin because opportunity cost keeps increasing as resources are shifted between the two goods. This happens since resources are not equally efficient in producing both goods.

Q4: Discuss the subject matter of economics.
Ans: The subject matter of economics is usually divided into two main branches: microeconomics and macroeconomics. These branches were named by Ragnar Frisch after 1930.
(i) Microeconomics
(ii) Macroeconomics
Q5: Distinguish between a centrally planned economy and a market economy.
Ans:

Q6: What do you understand by positive economic analysis?
Ans:

Q7: What do you understand by normative economic analysis?
Ans: Normative economic analysis deals with value judgments about what ought to be. It expresses opinions on desirable policies and goals, and it cannot be tested or proven true or false purely by facts.
