GBA common mistakes
GBA · Understand the traps and how to avoid them.
Treating a country's institutional environment as a single variable (e.g., 'high uncertainty avoidance means slow entry') instead of separating legal, political, and economic dimensions when recommending a market entry mode.
Candidates memorize Hofstede or PESTEL labels as one-line heuristics and then force a single cultural score to explain a decision that actually hinges on ownership rules, capital controls, or tariff structure. The exam deliberately builds scenarios where cultural and regulatory signals point in different directions.
What to do instead
Before answering, write down which institutional layer the question is really testing: formal rules (law, FDI caps, tax), informal norms (culture, trust), or market economics. Evaluate each separately, then state explicitly which one dominates the recommendation and why the others are secondary. Reject any option that collapses all three into one dimension.
Choosing a market entry mode (export, licensing, JV, wholly owned subsidiary) by ranking control versus risk in the abstract, without tying the choice to the specific asset, contract, and exit conditions described in the scenario.
Textbook tables present entry modes on a control/commitment spectrum, so candidates pick the 'middle' option or the highest-control option regardless of whether the scenario involves a dissipating know-how asset, a local partner with required government ties, or a reversible pilot.
What to do instead
Identify the transaction-specific driver first: is the firm's advantage tacit and easily copied (favor control), is local presence legally mandated (favor JV or local partner), or is demand unproven (favor low-commitment export or pilot)? Then check the option against that driver and against exit cost. Name the driver in your reasoning so the choice is defensible.
Standardizing the marketing mix globally because 'the product is universal', ignoring mandatory local adaptations such as labeling language, measurement units, advertising restrictions, or price-positioning norms.
Standardization is presented as the cost-efficient default, and candidates underweight compliance-driven adaptation because it appears administrative rather than strategic. Exam items often hide a legal requirement inside a pricing or promotion scenario.
What to do instead
Run a mandatory-versus-discretionary check: list adaptations required by law or regulation (language, warnings, units, claims, channel restrictions) separately from adaptations chosen for competitive reasons. Treat mandatory items as non-negotiable costs in the business case, and only debate the discretionary ones on margin and brand grounds.
Setting a single global price or a cost-plus local price without accounting for transfer pricing, grey-market arbitrage, or purchasing-power differences across markets.
Candidates compute price from unit cost plus target margin and stop there, forgetting that parallel imports and internal transfer prices change the realized margin and create channel conflict.
What to do instead
Build the price from three inputs: local willingness to pay, landed cost including duties and transfer price, and the arbitrage spread versus other markets. If the spread is large enough to invite grey imports, adjust the price corridor or the channel structure and say so explicitly.
Diagnosing a cross-cultural team conflict as a personality clash or a 'communication style' problem rather than tracing it to differing expectations about hierarchy, directness, or decision authority.
Candidates default to generic teamwork advice (more meetings, clearer goals) because it sounds safe, but the scenario usually encodes a specific norm difference such as who may challenge whom in public.
What to do instead
Map the conflict to a concrete norm dimension: power distance (who decides), directness (how feedback is given), or time orientation (deadline versus relationship). Then prescribe a mechanism that fits, such as a written pre-read to depersonalize dissent or a decision-rights chart. State the norm you identified.
Recommending a leadership style (participative, directive) as universally better instead of matching it to follower readiness, cultural expectations, and the decision's risk profile.
Leadership questions reward confident single answers, and candidates carry a bias that participative is always superior, even when the scenario involves a crisis, low-skilled team, or a culture where public consultation undermines authority.
What to do instead
Assess three variables before choosing: urgency and reversibility of the decision, the team's competence and experience, and local expectations about who holds authority. Justify the style against those three, and note the cost of the alternative (e.g., directive style erodes buy-in over time).
Analyzing a foreign project using only the parent company's domestic discount rate, ignoring currency risk, country risk premium, and the difference between project cash flows and remittable cash flows.
Candidates apply a single WACC from memory and forget that a foreign project's cash flows may be blocked, taxed on repatriation, or exposed to depreciation of a non-convertible currency.
What to do instead
Separate the analysis into project cash flow, financing effects, and repatriation. Apply a country risk adjustment to the discount rate or to the cash flows (not both), and explicitly model withholding taxes, remittance restrictions, and expected currency depreciation. Show the remittable cash flow line.
Consolidating foreign subsidiary results without applying the correct translation method, or mixing transaction exposure with translation exposure when recommending a hedge.
Candidates conflate accounting translation (balance-sheet effect, no cash impact) with transaction exposure (contractual cash flows), and then recommend a hedging instrument that addresses the wrong risk.
What to do instead
Label the exposure first: transaction (known foreign-currency cash flows), translation (converting subsidiary statements), or economic (long-run competitive effect). Hedge transaction exposure with forwards or options; treat translation exposure as an accounting policy choice. Match the instrument to the labeled exposure.
Answering a trade-compliance question by quoting the general tariff rate while ignoring rules of origin, preferential trade agreements, or classification of the good.
Candidates treat duty as a flat percentage and overlook that the applicable rate depends on HS classification and whether origin criteria are met under a free trade agreement, which is often the actual point of the question.
What to do instead
Walk the sequence: classify the good, determine origin and whether a preferential agreement applies, then apply the resulting rate. If origin qualification requires regional value content, check whether the sourcing changes it. State the rate you are applying and its legal basis.
Designing a global supply chain for lowest unit cost while ignoring disruption exposure, inventory positioning, and total landed cost including lead-time variability.
Cost-minimization is the intuitive objective, and candidates underweight the cost of stockouts, expediting, and single-source concentration until a disruption scenario forces the issue.
What to do instead
Compute total landed cost (unit cost plus freight, duty, inventory carrying cost, and expected disruption cost), then test the network against a single-node failure. Recommend decoupling points or dual sourcing where the failure cost exceeds the savings from concentration, and quantify the trade-off.
Choosing a project delivery method (waterfall, agile, staged) without considering regulatory gates, contract type, and the geographic distribution of the team.
Candidates pick agile as the modern default even when the scenario involves fixed-price contracts, regulatory approval milestones, or a client that cannot co-locate, all of which constrain iterative delivery.
What to do instead
Screen the context first: contractual flexibility, regulatory approval checkpoints, stakeholder availability, and team distribution. Select the method that fits those constraints, and if you recommend a hybrid, specify which phases are gated and which are iterative.
Treating an ethics or compliance question as a legal-minimum question, picking the option that is lawful but ignores the firm's own code, disclosure obligations, or reputational exposure in the host country.
Candidates reason 'if it is legal it is acceptable' and miss that exam scenarios test the gap between local law, home-country law (e.g., anti-bribery statutes with extraterritorial reach), and company policy.
What to do instead
Apply the strictest applicable standard across host law, home law, and internal code, then check disclosure and third-party (agent, intermediary) risk. If the options differ only in degree, choose the one that satisfies all three layers and explain which layer binds.
Recommending a digital transformation as a technology purchase (new ERP, cloud migration) without addressing data governance, process ownership, or change management across country units.
Candidates equate transformation with system implementation and skip the organizational prerequisites, so the answer sounds plausible but fails the scenario's constraint about local data-residency rules or resistant country managers.
What to do instead
Structure the answer as process, data, people, then technology. Name the data-residency or privacy constraint that shapes the architecture, identify who owns the process after go-live, and specify the change-management step for country units. Technology is the last layer, not the first.
Presenting sustainability as a cost or a reporting exercise rather than linking it to materiality, regulatory disclosure requirements, and the specific stakeholder or financing consequence in the scenario.
Candidates default to generic 'it improves reputation' answers and miss that the question tests double materiality, supply-chain due diligence obligations, or the cost of capital effect of disclosure.
What to do instead
Identify the material issue and the binding driver: mandatory disclosure regime, customer or lender requirement, or operational risk. Then state the concrete action and the measurable consequence (access to capital, contract eligibility, license to operate). Avoid reputation-only reasoning.
