Q2. What does the problem of "for whom to produce" refer to? 

Ans. The problem of "for whom to produce" refers to deciding who will ultimately consume the goods produced. Since resources are limited in every economy, no society can satisfy all its citizens' desires. This economic problem essentially focuses on the distribution mix of the final goods and services produced.

As a result, this choice involves determining how the final goods and services are distributed, which is similar to how national income (or national product) is distributed among various production factors such as land, labor, capital, and entrepreneurship.

The issue can be divided into two categories:

1. Personal Distribution:

   • This refers to how an economy's national income is distributed among different groups of people.

2. Functional Distribution:

   • This involves determining the proportion of various production factors in the country's total national product.
