Question

(a) Describe the mechanism of credit creation by commercial banks and its implications on multiplier effect. Analyse some of the limitations that can jeopardise the implications on multiplier effect. (10+10=20 marks)

(b) Distinguish between public goods and private goods. Explain how market failure occurs in the case of public goods. (7+8=15 marks)

(c) What is the difference between Fisher's theory and Cambridge cash balance approach to quantity theory of money? What is the criticism of each? Which one is more relevant in present context? Justify. (8+4+3=15 marks)

The question demands analytical depth across three distinct areas: credit creation mechanisms, public goods theory, and monetary theory comparisons. Allocate approximately 40% of time/words to part (a) given its 20 marks, 30% each to parts (b) and (c). Structure with a brief composite introduction, then address each sub-part sequentially with clear sub-headings, ensuring part (a) includes both descriptive and analytical elements, part (b) distinguishes clearly before explaining market failure, and part (c) systematically compares before evaluating contemporary relevance. Conclude with a synthesis on the evolution of monetary and fiscal policy frameworks in India.
- Part (a): Credit creation process through fractional reserve banking, money multiplier formula (1/CRR), and how deposits generate loans that re-enter banking system
- Part (a): Limitations including leakages (currency drain), excess reserves, non-availability of credit-worthy borrowers, and RBI's CRR/SLR adjustments affecting multiplier
- Part (b): Distinction based on rivalry and excludability—public goods (non-rival, non-excludable) vs private goods; pure vs impure public goods
- Part (b): Market failure via free-rider problem, non-revelation of true preferences, underprovision or non-provision by private markets, and government provision necessity
- Part (c): Fisher's transactions approach (MV=PT, flow concept, emphasis on medium of exchange) vs Cambridge cash balance (M=kPY, stock concept, demand for money as store of value)
- Part (c): Criticisms—Fisher's neglect of interest rates, Cambridge's static assumptions; relevance of Cambridge approach for modern monetary policy targeting inflation through interest rates
- Integration: Connection between credit creation limits and RBI's liquidity management; public goods provision in India's digital infrastructure; quantity theory relevance for inflation targeting framework

Dimension	Weight	Max marks	Excellent	Average	Poor
Concept correctness	22%	11	Precise exposition of money multiplier mechanics with correct formula; accurate distinction between rivalry/excludability for public goods; flawless comparison of Fisher's flow vs Cambridge stock approaches with correct equations; no conceptual conflation between transaction and precautionary motives	Generally correct concepts but minor errors in multiplier formula, incomplete distinction between public good types, or conflation of Fisher and Cambridge variables without clear differentiation	Fundamental errors such as confusing credit creation with money printing, misapplying rivalry/excludability criteria, or presenting identical equations for both quantity theory approaches
Diagram / model	18%	9	Clear T-account or balance sheet demonstration of credit creation rounds; well-labelled demand-supply diagram for public goods showing underprovision; graphical representation of Cambridge k vs Fisher's V relationship; integrated diagrams showing CRR impact on multiplier	Basic T-account without multiple rounds, generic market failure diagram without public goods specificity, or textual description where diagram would clarify	Missing diagrams entirely, incorrect diagram construction, or diagrams that misrepresent the economic relationships described
Quantitative reasoning	16%	8	Numerical illustration of multiplier with assumed CRR (e.g., 4% → 25x multiplier), demonstration of leakage effects on effective multiplier, quantitative comparison of income velocity vs Cambridge k, or empirical money supply data from RBI	Mention of formula without numerical application, or generic statement about multiplier size without calculation	No quantitative element, incorrect arithmetic in illustration, or confusion between nominal and real values in quantity theory application
Indian / empirical examples	22%	11	RBI's CRR/SLR adjustments post-2016 demonetization or during COVID-19 liquidity management; India's public goods provision in defence, street lighting, or Aadhaar infrastructure; empirical validation of Cambridge approach through RBI's inflation targeting since 2016; reference to Narasimham Committee on banking reforms	Generic mention of RBI without specific policy episode, standard public goods examples without Indian context, or dated references without contemporary relevance	No Indian examples, irrelevant international cases where Indian examples exist, or factually incorrect references to Indian monetary institutions
Policy implication	22%	11	Critical analysis of how RBI uses CRR as credit control instrument affecting multiplier; evaluation of government provision vs public-private partnerships for public goods; assessment of why Cambridge approach better suits flexible inflation targeting framework; synthesis on monetary-fiscal coordination	Descriptive policy mention without critical evaluation, or standard textbook recommendations without application to contemporary Indian economic challenges	Missing policy dimension entirely, or irrelevant policy suggestions that contradict established RBI/government frameworks
