Economic Moats & Macro

Question 1 (10 marks)

(a) Mechanisms (1 mark each):

• Network effect: each new user increases value to all existing users, so competitors face a value gap they cannot match at low scale.
• Cost advantage: producer can undercut on price and still profit, so rivals bleed if they match.
• Brand/intangible: pricing power + consumer trust/patents raise willingness to pay and legally block imitation.
• Switching cost: cost/effort/risk of changing suppliers locks customers in, reducing churn.

(b) Durability threats (1 mark each):

• Network → technological disruption / multi-homing (users on several platforms).
• Cost → new low-cost technology or cheaper geography erasing the edge.
• Brand → shifting consumer preference, scandal, or commoditisation.
• Switching → open standards / interoperability regulation lowering switch cost.

(c) (2 marks): Network effect — value grows with users, creating a positive feedback loop (winner-take-most) that self-reinforces as it scales. (1 mark answer, 1 mark justification)

Question 2 (12 marks)

(a) Five Forces (1 each):

1. Threat of new entrants
2. Bargaining power of suppliers
3. Bargaining power of buyers
4. Threat of substitutes
5. Competitive rivalry among existing firms

(b) Cement producer (1 each, reason required):

• New entrants — LOW (huge capex, limestone reserves, licences).
• Supplier power — MEDIUM (energy/coal costs volatile but multiple sources).
• Buyer power — MEDIUM (fragmented retail buyers, but bulk infra buyers negotiate).
• Substitutes — LOW (few alternatives to cement in construction).
• Rivalry — HIGH (commodity product, price competition, regional overcapacity).

(c) (2 marks): A cost-advantage moat lowers rivalry threat (firm survives price wars competitors can't) and lowers threat of new entrants (entrants can't match unit economics). (1 mark per correctly-mapped force with logic)

Question 3 (10 marks)

(a) Real GDP growth (4 marks): Nominal growth = $224/200 - 1 = 12\%$. (1) Relationship: $(1+g_{nom}) = (1+g_{real})(1+\text{deflator})$. (1) $1+g_{real} = \frac{1.12}{1.05} = 1.06667$ (1) $g_{real} \approx 6.67\%$ (1) (Approximation 12% − 5% = 7% acceptable for partial credit but exact is 6.67%.)

(b) CPI inflation (3 marks): $\text{Inflation} = \frac{162-150}{150} = \frac{12}{150} = 8\%$ (3)

(c) (3 marks): WPI tracks wholesale/producer goods (no services, weighted to manufacturing/fuel) while CPI includes retail services and food; different baskets → divergence, especially when food or fuel spikes. (2) The RBI targets CPI (flexible inflation targeting, 4% ±2%). (1)

Question 4 (12 marks)

(a) Bond price (5 marks): Cashflows: ₹6, ₹6, ₹106 discounted at 8%. (1 for setup) $P = \frac{6}{1.08} + \frac{6}{1.08^2} + \frac{106}{1.08^3}$ (1) $= 5.5556 + 5.1440 + 84.1520$ (2 for correct discounting) $P \approx ₹94.85$ (1) (Below par because coupon 6% < yield 8%.)

(b) Transmission chain (5 marks, 1 each):

1. Repo ↑ → borrowing cost for banks from RBI rises.
2. Banks raise lending/deposit (MCLR/EBLR) rates → credit costlier, demand slows.
3. Higher prevailing yields → existing bond prices fall (inverse relationship).
4. Discount rate for equity cash flows rises → present value of future earnings falls → equity valuations (P/E) compress.
5. Rate-sensitive sectors (autos, real estate, NBFCs) hit hardest; growth/long-duration equities de-rate more.

(c) (2 marks): Bond price ↓ when yields rise. (1) Long-duration bonds have cash flows further out, so a higher discount rate compounds over more periods → greater price sensitivity (higher duration). (1)

Question 5 (10 marks)

(a) Four phases (4 marks, 1 each, order matters): Expansion → Peak → Contraction (recession) → Trough (recovery), then repeats.

(b) Sector rotation (4 marks):

• Early recovery: Financials / cyclicals (autos, industrials) — rate-sensitive demand rebounds, credit growth picks up. (2)
• Late-cycle/peak: Energy / materials / commodities — inflation and capacity utilisation peak, pricing power high. (2)

(c) (2 marks): Phase = stagflation-tilted contraction / late-cycle slowdown. (1) Tilt defensive: FMCG / pharma / utilities (inelastic demand). (1)

Question 6 (6 marks)

(a) (4 marks):

• Bond yields: larger deficit → govt borrows more → increased bond supply pushes prices down / yields up (crowding out). (2)
• Currency: higher deficit raises inflation/import-financing needs and can dent foreign investor confidence → capital outflows / weaker currency. (2)

(b) (2 marks): Helps: exporters/IT earn more in rupee terms (competitiveness). (1) Hurts: importers and firms with dollar debt face higher costs, imported inflation. (1)
