Q.Explain, with a suitable example, what is meant by the central problem of 'What to produce' in an economy.

'What to produce' is the decision about which goods (and how much of each) an economy should make with its limited resources, since producing more of one good means less of another.

For example, a country with limited arable land must decide how much of it to devote to food grains versus cash crops like cotton, since land used for one cannot simultaneously grow the other.

The central problem of 'What to produce' arises directly from scarcity: since an economy's resources — land, labour, capital and entrepreneurship — are limited, it is impossible to produce every good and service that people might want, in whatever quantity they might want it. The economy must therefore decide WHICH goods and services to produce, and in WHAT QUANTITIES, out of all the goods it is technically capable of producing.

This decision has two related dimensions: first, choosing the broad CATEGORY of goods — for instance, whether to devote more resources to consumer goods (like food and clothing) or capital goods (like machinery and factories) that will expand future production; and second, choosing the PROPORTION or quantity of each specific good within that category — for instance, how much arable land a country devotes to food grains versus cash crops such as cotton or sugarcane, given that land used to grow one crop cannot simultaneously be used to grow another. Whatever choice is made, the resources used to produce one good represent an opportunity cost — the alternative good that could have been produced instead but was not.

Students sometimes describe 'what to produce' only in terms of a single good (e.g. 'how much wheat to grow') without recognising it is fundamentally a CHOICE AMONG competing goods — the problem is comparative (this good versus that good), not about any one good in isolation.
