In a twosector economy model, the economy is simplified to two main sectors: households and firms. 1. Households:
Households own the factors of production, such as land, labor, capital, and entrepreneurship. They provide these factors to firms in exchange for income, which includes wages, rents, interests, and profits. 2. Firms:
Firms are the producers of goods and services. They use the factors of production from households to produce goods and services, which are sold to households. In return, firms pay income to households for their factors of production. Flow of Income and Expenditure:
Households spend their income on the goods and services produced by firms (Consumption Expenditure).
Firms, in turn, provide goods and services to households in exchange for payment, which is their revenue. Circular Flow:
The flow of goods and services from firms to households and the flow of income from households to firms forms a continuous cycle, known as the circular flow of income. Equilibrium in the Circular Flow:
The economy reaches equilibrium when total income generated in the economy (from the sale of goods and services) is equal to the total expenditure (households' consumption expenditure).
Conclusion: In a twosector model, the economy functions as a closed loop where households provide factors of production to firms, and firms return income to households in exchange for goods and services.
Read the following statements carefully:
Statement 1: Expost savings and Expost investments are equal at all levels of income.
Statement 2: Under the effective demand principle, the equilibrium output is equal to exante Aggregate Demand (AD). In the light of the given statements, choose the correct alternative from the following:
The level of income where Average Propensity to Save (APS) becomes zero is at Income = Rs. 100 crore, since savings (\( S = Y - C \)) equals zero at this point.
Identify, what does the shaded area (change in EFG), in the given figure indicate?

I. Consumption > Income
II. Saving = Zero (0)
III. Consumption < Income
IV. Saving < Zero (0)
