Apply

A small coffee shop processes 200 transactions per day with an average ticket of EUR 5. Applying the cost comparison framework, which payment method would minimize the shop's total payment processing costs?

A.Premium credit cards, because they offer rewards to customers B.Debit cards or real-time payment systems, because they charge lower per-transaction fees, which is critical when the average ticket size is small C.Cash only, because it has zero processing costs D.Corporate charge cards, because they settle faster

7

Apply

India's UPI processed over 10 billion transactions per month by 2023. Applying the network effects framework, which factor was most critical to achieving this scale?

A.UPI uses the most advanced blockchain technology B.The government-mandated zero merchant discount rate eliminated cost barriers, driving rapid adoption by merchants, which in turn attracted more consumers through two-sided network effects C.India has the world's highest smartphone penetration rate D.UPI was the first digital payment system launched in Asia

8

Apply

The EU Interchange Fee Regulation caps consumer credit card interchange at 0.3% and debit at 0.2%. Apply this regulation: what happens to the merchant discount rate a European retailer pays?

9

Apply

A migrant worker in the US wants to send USD 200 to family in the Philippines. Based on the remittance cost framework, approximately what percentage of the transfer would be lost to fees and exchange rate margins using traditional channels?

A.Less than 1%, because international transfers are highly competitive B.Approximately 6-7% on average globally, with some corridors exceeding 10%, driven by FX margins, correspondent bank fees, and compliance costs C.Exactly 0.3%, matching the EU interchange fee cap D.Over 25%, because of US government regulations

10

Apply

Brazil launched PIX in November 2020. By applying the payment innovation adoption framework, which design feature most explains why PIX achieved 150 million users within two years?

A.PIX uses cryptocurrency as its settlement layer B.PIX is only available to large corporations C.The central bank mandated participation by all licensed financial institutions, ensuring instant interoperability and 24/7 settlement at zero cost to end users D.Brazil eliminated all other payment methods when PIX launched

11

Apply

A stablecoin issuer claims its token is fully backed 1:1 by US dollar reserves. Applying the payment instrument trust framework, which risk does this arrangement NOT eliminate?

A.Foreign exchange risk B.Counterparty risk -- the issuer may not actually hold the reserves it claims, may invest them in risky assets, or may face a run that depletes reserves C.Inflation risk of the underlying fiat currency D.Technology risk of the blockchain platform

12

Apply

The US Durbin Amendment caps debit card interchange fees at approximately 21 cents plus 0.05% per transaction for large banks. Apply this framework: which merchant type benefits most from this cap?

A.Small coffee shops with average transactions under USD 5 B.Large retailers like grocery chains and big-box stores with high average transaction values, because the capped flat fee is far below the percentage-based fee they would otherwise pay on large transactions C.Online-only merchants who process no in-person transactions D.All merchant types benefit equally from the Durbin Amendment

13

Analyze

Why has India's UPI achieved significantly higher adoption rates than the US FedNow system launched in 2023?

A.US technology infrastructure is inferior to India's B.UPI launched into a market with limited card infrastructure and high unmet demand, with government-mandated zero fees and mandatory bank participation. FedNow entered a market already saturated with card networks, where banks have little incentive to cannibalize existing revenue streams. C.FedNow charges higher fees than credit cards D.Americans prefer cash over all digital payment methods

14

Analyze

Why do payment networks like Visa and Mastercard operate as two-sided markets, and how does this structure affect their pricing strategy?

A.They charge identical fees to both merchants and cardholders B.As two-sided platforms, they subsidize the cardholder side (rewards, zero fees) to maximize card adoption, then recover costs from the merchant side (interchange), because merchants accept cards to access the cardholder base. This cross-subsidy is the economic logic of interchange. C.They only serve merchants, not consumers D.Two-sided markets always result in lower prices for everyone

15

Analyze

Analyze why Scandinavian countries have nearly eliminated cash while Germany and Japan maintain high cash usage despite similar levels of technological development.

A.Scandinavian countries have better technology infrastructure B.The difference is driven by cultural attitudes toward privacy and state trust: Germans and Japanese value transaction anonymity and distrust centralized digital records, while Scandinavians exhibit high institutional trust and accept the transparency that digital payments entail C.Cash is illegal in Scandinavian countries D.Germany and Japan do not have digital payment systems available

16

Analyze

Analyze the 'waterbed effect' in interchange fee regulation: when regulators cap interchange fees, what compensating behavior do issuing banks typically exhibit?

A.Banks absorb the loss with no changes to consumer products B.Banks reduce cardholder rewards, introduce or increase annual card fees, and raise interest rates to recover lost interchange revenue -- effectively shifting costs from merchants to cardholders C.Banks stop issuing cards entirely D.Banks increase lending to small businesses instead

17

Analyze

Why is the 'direct' CBDC model (where the central bank manages individual accounts for all citizens) considered problematic by most central banks?

A.Central banks lack the computing power to manage individual accounts B.It would disintermediate commercial banks by shifting deposits directly to the central bank, undermining the fractional reserve banking system, reducing banks' ability to extend credit, and creating operational risks by concentrating KYC/AML responsibilities in a single institution C.Consumers prefer to hold accounts only with private banks D.International law prohibits central banks from holding individual accounts

18

Analyze

Analyze why cross-border payments remain significantly more expensive and slower than domestic payments, despite decades of technological progress.

A.Cross-border payments use older technology that cannot be upgraded B.The friction is structural, not technological: different regulatory regimes, AML/KYC compliance across jurisdictions, time zone mismatches, correspondent banking chains, FX conversion, and the absence of a single global settlement infrastructure create layers of cost and delay C.Banks deliberately slow down transfers to earn interest on float D.SWIFT charges excessively high fees for all messages

19

Evaluate

Evaluate the claim that CBDCs will eliminate the need for commercial bank intermediation in the payments system.

A.The claim is correct -- CBDCs will fully replace commercial banks B.The claim overstates the disruption. Most CBDC designs deliberately preserve commercial bank intermediation through the 'intermediated' or 'two-tier' model, where banks distribute the CBDC and maintain customer relationships. Full disintermediation would destabilize the banking system. C.CBDCs are technologically impossible D.Commercial banks will block all CBDC development

20

Evaluate

Evaluate whether interchange fee regulation ultimately benefits consumers. Consider both sides of the argument.

A.Interchange fee regulation unambiguously benefits all consumers B.The net consumer impact is ambiguous: merchants pay lower fees but may not fully pass savings to consumers, while cardholders face reduced rewards and higher annual fees. The distributional effect shifts costs from non-card-using consumers (who previously subsidized rewards) to card users. C.Interchange fee regulation only harms consumers D.Interchange fees have no connection to consumer prices
