Try three different Economics skills from this Pearson Edexcel · Economics B route. See what went right, understand a mistake, and find a useful next step.
A small preview of how LearningP turns answers into a clearer learning picture for students and parents.
Scarcity exists because finite resources cannot satisfy every competing want, so choosing one use entails an opportunity cost. The common error is: Scarcity means a product is rare rather than that resources are limited relative to wants.
A manager rewarded for market share may expand output beyond the profit-maximising quantity toward sales-revenue maximisation. This is valid because Profit is maximised where marginal revenue equals marginal cost, while revenue is maximised where marginal revenue equals zero, subject to the relevant curves and constraints. The rejected shortcut is incorrect: Profit and sales revenue are maximised at the same output because both rise whenever output rises.
A supported judgement states the economic mechanism and applies it to the context. A tariff benefits protected producers and raises government revenue but reduces consumer surplus and creates production and consumption deadweight losses in the standard small-country model. Therefore, The higher domestic price expands inefficient domestic output and suppresses some mutually beneficial consumption. Avoid this misconception: A tariff's producer gain and government revenue always exceed the consumer loss.
These tiles show your answers to three questions. They are a starting point, not a mastery score or grade prediction.

For parents: look at the explanation together. A correct answer is encouraging; a missed answer gives you something specific to work on. Broader practice over time is needed to understand progress.
A positive statement is testable against evidence, whereas a normative statement contains a value judgement about what ought to happen. The common error is: Any statement containing a number is normative and every statement without a number is positive.
Watch for: Do not stop after the first effect of Scarcity, choice and potential conflicts. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.

Watch for: Do not stop after the first effect of Enterprise, business and the economy. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
A non-price determinant such as income, tastes, population or a related good's price shifts demand at every own-price level. The common error is: A fall in the product's own price shifts demand right rather than causing an extension along the curve.
Watch for: Do not stop after the first effect of Introducing the market. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Financial institutions mobilise saving, assess and diversify risk, provide payments, transform maturities and allocate funds to investment. The common error is: Financial intermediation removes all risk because savers never face default or liquidity problems.
Watch for: Do not stop after the first effect of The role of credit in the economy. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
With a negative externality, marginal social cost exceeds marginal private cost by the marginal external cost imposed on third parties. The common error is: External cost is the whole cost to society, so it equals private cost plus social cost.
Watch for: Do not stop after the first effect of Market failure and government intervention. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
In the short run, adding a variable factor to fixed factors eventually causes marginal product to fall, which tends to make marginal cost rise. The common error is: Diminishing returns means total output must immediately fall when one more worker is hired.
Watch for: Do not stop after the first effect of Revenue, costs, profits and cash. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Cooperatives may prioritise member benefit while investor-owned firms may emphasise shareholder returns. Neither form guarantees efficiency because decision rights, capital access and management matter.
Watch for: Do not stop after the first effect of Business growth and competitive advantage. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
PED equals percentage change in quantity demanded divided by percentage change in price; its magnitude shows responsiveness and its sign is normally negative. The common error is: PED is calculated by dividing the cash price change by the change in units sold.
Watch for: Do not stop after the first effect of Firms, consumers and elasticities of demand. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
With fixed capital, crowding and coordination eventually reduce the extra output from each worker. If the wage is unchanged, producing each additional unit then requires more labour and raises MC.
Watch for: Do not stop after the first effect of Productive efficiency. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
A supported judgement states the economic mechanism and applies it to the context. A tariff benefits protected producers and raises government revenue but reduces consumer surplus and creates production and consumption deadweight losses in the standard small-country model. Therefore, The higher domestic price expands inefficient domestic output and suppresses some mutually beneficial consumption. Avoid this misconception: A tariff's producer gain and government revenue always exceed the consumer loss.
Watch for: Do not stop after the first effect of Life in a global economy. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Real GDP growth measures change in total real output; real GDP per capita divides by population and can move differently when population changes. The common error is: Any rise in real GDP guarantees the average material living standard rises.
Watch for: Do not stop after the first effect of The economic cycle. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Faster domestic growth can raise imports and worsen the current account, but export-led growth or improved competitiveness can raise output while strengthening it. The common error is: A growing economy must always have a current-account deficit.
Watch for: Do not stop after the first effect of Introduction to macroeconomic policy. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
The relevant counterfactual is whether investment occurs without the incentive and what durable domestic benefits it creates. Competition between countries can transfer excessive value to the TNC.
Watch for: Do not stop after the first effect of Globalisation. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Trade creation replaces higher-cost domestic output with lower-cost imports from a member, improving resource allocation. Trade diversion replaces a cheaper outsider because of discriminatory tariffs.
Watch for: Do not stop after the first effect of Economic factors in business expansion. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Globalisation is increasing cross-border integration of goods, services, capital, production, technology and information, enabled by policy and falling coordination costs. The common error is: Globalisation means only a rise in physical merchandise exports.
Watch for: Do not stop after the first effect of Impact of globalisation on global companies. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
A supported judgement states the economic mechanism and applies it to the context. Depreciation tends to improve the trade balance when the sum of long-run export and import demand elasticity magnitudes exceeds one; contractual lags can cause an initial worsening described by the J-curve. Therefore, Import values may rise immediately after depreciation before quantities adjust, then improve later if demand is sufficiently elastic. Avoid this misconception: The Marshall-Lerner condition guarantees immediate improvement before contracts or quantities change.
Watch for: Do not stop after the first effect of Impact of globalisation on local and national economies. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
At higher wages the income effect of a wage rise may exceed the substitution effect, causing an individual to choose more leisure and fewer working hours. The common error is: A backward-bending supply curve means employers demand less labour when wages rise.
Watch for: Do not stop after the first effect of Global labour markets. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Income is a flow received over time, while wealth is a stock of accumulated assets net of liabilities at a point in time. The common error is: Income and wealth are identical because both are measured in money.
Watch for: Do not stop after the first effect of Inequality and re-distribution. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
A firm in monopolistic competition maximises profit where MC equals MR and may earn supernormal profit or a loss in the short run. The common error is: Product differentiation forces price to equal marginal cost in every short-run equilibrium.
Watch for: Do not stop after the first effect of Competition and market power. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Rate-of-return regulation can encourage excessive capital spending or cost inflation because a larger approved base supports more allowed profit. Regulatory scrutiny must distinguish efficient investment.
Watch for: Do not stop after the first effect of Market power and market failure. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Reduced charged-zone traffic is a benefit, but diverted congestion and pollution are external effects of policy design. Evaluation should measure the whole network and refine complementary transport or pricing measures.
Watch for: Do not stop after the first effect of Market failure across the economy. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
Stimulating demand can reduce cyclical unemployment but increase inflation near capacity. The short-run Phillips curve represents this possible inverse relationship, though it is not stable in all conditions.
Watch for: Do not stop after the first effect of Macroeconomic policies and impact on firms and individuals. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
A supported judgement states the economic mechanism and applies it to the context. A central bank conducts monetary policy, issues currency, manages reserves, supports payment systems and may act as lender of last resort and supervisor, depending on the institutional framework. Therefore, Emergency liquidity to a solvent bank facing a temporary run can limit contagion, but lending to an insolvent bank creates moral-hazard and fiscal concerns. Avoid this misconception: Lender of last resort means permanently financing every loss-making financial institution.
Watch for: Do not stop after the first effect of Risk and the financial sector. Build the chain of reasoning, use the context and explain what could weaken or reverse the outcome.
