Correct Option
The correct option is 1 and 3 only.
Explanation
In a mixed economy, economic activities are divided between the public sector (government-owned) and the private sector (privately owned). The fundamental distinction lies in their objectives: the public sector focuses on social welfare and the provision of public goods, while the private sector is primarily driven by profit maximization.
Statement-wise Analysis:
- Statement 1 is Correct: The primary objective of the public sector is to ensure social welfare and equitable distribution of resources. Unlike private enterprises that operate for profit, public sector entities often undertake projects that benefit society as a whole, even if they are not immediately profitable.
- Statement 2 is Incorrect: Governments do not rely solely on donations. The primary sources of government revenue are taxes (direct and indirect), non-tax revenues (fees, fines, dividends from PSUs), and borrowings. While governments may accept donations (e.g., relief funds), they constitute a negligible portion of the total budget.
- Statement 3 is Correct: There are certain essential services and goods (often termed public goods or merit goods), such as sanitation, roads, bridges, and railways, which require massive capital investment and have long gestation periods. The private sector may not provide these goods at a reasonable cost due to the lack of immediate profit or the inability to charge users effectively (non-excludability). Therefore, government intervention is necessary to ensure their availability to all citizens.
Key Takeaway:
The public sector exists to provide public goods and ensure social welfare, filling the gaps left by the profit-motivated private sector. Government expenditure is funded primarily through taxation and borrowing, not donations.
