Question 2.
Prepare a seminar paper on “central problems of an economy.
Answer:
Respected teachers and dear friends,
The topic of my seminar paper is “central problems of an economy”. As we know the central problems arise due to the fact that the human wants are unlimited and the means to satisfy those wants are limited. In this seminar paper, I would like to present the central problems such as what to produce, how to produce and for whom to produce.

Introduction:
The resources available to the consumer are limited but their wants are unlimited. Due to scarcity of resources, the economy faces the problem of choice. It is this mismatch between unlimited wants and the limited resources that gives rise to three central problems faced by every economy.

Contents:
a. What to produce and in what quantities?
An economy faces the problems of what to produce because the resources available to an economy are scarce. As resoruces are scarce, an economy cannot produce all those goods and services the society needs. Therefore, society has to take the crucial decision of what goods and services to be produced in an economy.

For example, the resources of an economy can be used for the production of food, defense equipment or luxury goods. It can also be used for education, health or entertainment. A national society has to make a priority list of items to be produced and allocate the available resources accordingly.

Once the decision regarding what to produce is taken, the next problem is to decide in what quantities the goods and services are to be produced. It is important because the production of one good may lead to the withdrawal of the production of some other goods.

b. How to produce?
After taking the decision regarding the type and quantity of goods to be produced, the next question is ‘how to produce goods arid services’. This problem is related to the method or technology of production. Goods can be produced using different technologies.

There are mainly two technologies for producing goods, viz., labor-intensive technology and capital intensive technology. Labour intensive technology uses more labour compared to capital. On the other hand, capital intensive technology uses more caiptal compared to labour. The choice of technique depends upon various factors like the availability of labour force and capital resources and its prices.

c. For whom to produce?
The goods and services produced once should be distributed among the people of the economy. Whether it should be distributed equally among the people? Should the distribution of the goods be in such a way that at least minimum consumption level has to be attained by everyone in the economy? Should everyone get primary health and education?

Conclusion:
Thus it can be concluded that every economic system faces three basic problems. The solution to these economic problems depends upon the nature of the economic system.
