Match List I with List II List I (Type of the definitions of... | Agrigyan

Distinction between Microeconomics and Macroeconomics:

• Statement (I) is false: The study of a particular firm, household, individual prices, and wages defines Microeconomics (not macroeconomics).
• Statement (II) is false: The study of aggregates, overall economy, national income, general price levels, and aggregate output defines Macroeconomics (not microeconomics).
• The definitions provided in the statements are exactly reversed; hence both statements are false.

Sectoral macroeconomic equilibrium models:

• Two-sector economy: Includes Households and Business Firms $\implies Y = C + I$.
• Three-sector economy: Adds the Government sector $\implies Y = C + I + G$, where $C$ is consumption, $I$ is investment, and $G$ is government expenditure.
• Four-sector (open) economy: Adds the External/Foreign sector $\implies Y = C + I + G + (X - M)$.
• Thus, $Y = C + I + G$ defines the equilibrium of the three-sector closed economy.

Explicit costs vs Implicit costs in economic analysis:

• Statement (I) is true: Explicit (out-of-pocket or paid-out) costs are direct monetary cash payments made to external suppliers for factors of production not owned by the farmer/entrepreneur (such as hired labor, rented land).
• Statement (II) is true: Cash expenditure incurred on purchased variable farm inputs like certified seeds, chemical fertilizers, and herbicides from the market represents direct explicit costs.
• Both statements are true.
