Question

Identify the correct statements :
(A) Stocks are defined over a period of time.
(B) Flows are defined over a period of time.
(C) Flows are defined at a particular point of time.
(D) Stocks are defined at a particular point of time.
(E) GVA at factor costs + Indirect Taxes – Subsidies = GVA at market prices.
Choose the correct answer from the options given below :

• A. (A), (C) and (E) only
• B. (B), (C) and (D) only
• C. (B), (D) and (E) only
• D. (C), (D) and (E) only

Answer 1

The Correct Option is C

The given statements need to be identified as true or false based on concepts of economics concerning stocks and flows, and the calculation of GVA (Gross Value Added) at different cost structures. 

Explanation:

(A) Stocks are defined over a period of time. - False. Stocks are measurements of quantities at a specific point in time, not over a period.

(B) Flows are defined over a period of time. - True. Flows measure quantities over a specific period of time, indicating the rate of change.

(C) Flows are defined at a particular point of time. - False. As mentioned, flows are defined over a time span.

(D) Stocks are defined at a particular point of time. - True. Stocks are static figures at a specific point in time.

(E) GVA at factor costs + Indirect Taxes – Subsidies = GVA at market prices. - True. This is the correct formula for calculating GVA at market prices. Gross Value Added at market prices is calculated by adjusting the GVA at factor costs with indirect taxes and subsidies.

Conclusion: The correct statements are based on basic economic definitions:

• (B) Flows are defined over a period of time.
• (D) Stocks are defined at a particular point of time.
• (E) GVA at factor costs + Indirect Taxes – Subsidies = GVA at market prices.

Hence, the correct answer is: (B), (D), and (E) only.

Answer 2

Flows refer to economic variables that are measured over a period of time. For example, income or expenditure represents flows because they are measured over a specific time period, such as a month, quarter, or year. Flows capture the movement of resources or economic activities within a time frame.

In contrast, stocks are economic variables that are defined at a particular point in time. For instance, wealth, capital stock, and debt are all stock variables, as they represent quantities at a specific moment, without considering the time period over which they were accumulated.

Gross Value Added (GVA) at market prices represents the total value of goods and services produced in an economy, excluding the costs of intermediate goods. It is calculated by adding up the value added in each sector of the economy. Additionally, GVA at market prices includes indirect taxes (such as VAT or excise taxes) and subtracts subsidies provided by the government. The formula for GVA at market prices is:

GVA = GVA at factor cost + Indirect taxes - Subsidies
