Key Economic Identities, Formulas & Business Principles

Price Elasticity of Demand & Supply

$$E_d = \left|\frac{\Delta Q}{\Delta P} \cdot \frac{P}{Q}\right| \quad ; \quad E_s = \frac{\Delta Q_s}{\Delta P} \cdot \frac{P}{Q_s}$$

Measures percentage responsiveness of quantity demanded/supplied to changes in market price.

Total, Average & Marginal Cost Relations

$$TC = TFC + TVC \quad ; \quad ATC = AFC + AVC \quad ; \quad MC = \frac{\Delta TC}{\Delta Q}$$

Short-run cost curves: MC cuts both ATC and AVC at their respective minimum points.

Consumer Equilibrium (Utility Theory)

$$\frac{MU_x}{P_x} = \frac{MU_y}{P_y} = MU_m \quad ; \quad MRS_{xy} = \frac{P_x}{P_y} \quad \text{(Indifference Curve)}$$

Equi-marginal utility condition equating price ratios to marginal rate of substitution.

Conceptual Solved Examples & Case Studies

Example 1

Problem 1: In an economy, the marginal propensity to consume (MPC) is 0.75. If autonomous investment increases by ₹500 crores, calculate: (i) Investment Multiplier ($k$), (ii) Total increase in National Income ($\Delta Y$), and (iii) Total increase in Consumption Expenditure ($\Delta C$).

Step-by-Step Solution:

Step-by-Step Solution:
1. Calculate Investment Multiplier ($k$):

$$k = \frac{1}{1 - MPC} = \frac{1}{1 - 0.75} = \frac{1}{0.25} = 4$$

2. Calculate Total Increase in National Income ($\Delta Y$):

$$\Delta Y = k \times \Delta I = 4 \times ₹500\,\text{crores} = ₹2,000\,\text{crores}$$

3. Calculate Total Increase in Consumption Expenditure ($\Delta C$):

$$\Delta C = MPC \times \Delta Y = 0.75 \times ₹2,000\,\text{crores} = ₹1,500\,\text{crores}$$

Check: $\Delta Y = \Delta C + \Delta I \implies 2,000 = 1,500 + 500$ (balances perfectly).

Example 2

Problem 2: When the price of a good is ₹10 per unit, its quantity demanded is 100 units. When price falls to ₹8 per unit, quantity demanded rises to 140 units. Calculate its price elasticity of demand ($E_d$).

Step-by-Step Solution:

Step-by-Step Solution:
1. Identify Changes:
Initial Price $P = 10$, New Price $P_1 = 8 \implies \Delta P = 8 - 10 = -2$.
Initial Quantity $Q = 100$, New Quantity $Q_1 = 140 \implies \Delta Q = 140 - 100 = +40$.
2. Formula Application:

$$E_d = -\left(\frac{\Delta Q}{\Delta P} \times \frac{P}{Q}\right) = -\left(\frac{40}{-2} \times \frac{10}{100}\right) = -(-20 \times 0.1) = 2.0$$

3. Interpretation: Since $E_d = 2.0 > 1$, the demand is highly price elastic (a 20% price drop induces a 40% expansion in quantity demanded).

Common Misconceptions & Examiner Traps

Common Misconception

Writing long, unstructured paragraphs without clear thematic headings or numbered points.

Scientific Reality & Correction

Structure answers with distinct headings, bullet points, and an opening definition followed by concrete examples.

Common Misconception

Confusing related conceptual terms due to superficial memorization rather than deep conceptual understanding.

Scientific Reality & Correction

Create comparative summary tables highlighting exact operational differences, legal scopes, or functional distinctions.
