How Markets Work
224 questions in the guide, across 16 subtopics. More from this topic
-
Rational decision making
What objective does the rational decision-making model assume firms pursue?
Show the answer
Profit maximisation -
Price, income and cross elasticity: formulae and values
What variable appears in the denominator of the YED formula?
Show the answer
The percentage change in income. -
What determines the elasticity of demand
How does the time period affect PED?
Show the answer
Demand becomes more elastic over longer time periods as consumers have more time to find alternatives.
Paper 1, Paper 3
Market Failure
69 questions in the guide, across 5 subtopics. More from this topic
-
What market failure is, and social costs and benefits
Define private costs.
Show the answer
Private costs are the costs of production or consumption borne directly by the producer or consumer. -
What market failure is, and social costs and benefits
Define private benefits.
Show the answer
Private benefits are the benefits of production or consumption received directly by the producer or consumer. -
Externality diagrams and welfare loss
Why do negative externalities of production lead to overproduction?
Show the answer
Because the market ignores external costs, so equilibrium is determined by private costs alone, leading to output beyond the socially optimal level.
Paper 1, Paper 3
Government Intervention
65 questions in the guide, across 4 subtopics. More from this topic
-
Indirect taxes and subsidies as interventions
How does an ad valorem tax affect the supply curve on a diagram?
Show the answer
It causes the supply curve to pivot and diverge from the original curve as price increases. -
Indirect taxes and subsidies as interventions
Explain why a subsidy shifts the supply curve downward.
Show the answer
Because the subsidy reduces the cost of production per unit, firms are willing to supply the same quantity at a lower price, or more quantity at the same price. -
Maximum and minimum prices, and tradable pollution permits
What is a minimum price?
Show the answer
A legally imposed floor below which the price of a good cannot fall.
Paper 2, Paper 3
Measures of Economic Performance
188 questions in the guide, across 12 subtopics. More from this topic
-
Measuring growth: real GDP, GDP per capita and GNI
Calculate the GDP per capita when total GDP = 2200 billion, population = 70 million.
Show the answer
GDP per capita = 2,200,000,000,000 ÷ 70,000,000 ≈ 31,429 currency units per person (about 31.4 thousand per person). -
Purchasing power parity and the limitations of GDP
What type of externality does GDP fail to account for, and why is this a limitation?
Show the answer
GDP does not account for negative externalities such as pollution and environmental degradation that reduce quality of life, meaning growth may come at hidden costs to welfare. -
Inflation, deflation and how the CPI measures them
How often is the CPI basket of goods updated, and why?
Show the answer

Show the answer
Net exports, also called the trade balance. -
The AD curve: why it slopes down and what shifts it
How does a lower domestic price level affect the competitiveness of exports according to the trade effect?
Show the answer
A lower domestic price level makes domestically produced goods cheaper relative to foreign goods, making exports more competitive in international markets.
Paper 2, Paper 3
Aggregate Supply
62 questions in the guide, across 4 subtopics. More from this topic
-
The characteristics of AS
How do changes in raw material prices affect the SRAS curve?
Show the answer
Higher raw material prices increase production costs, shifting the SRAS curve leftward; lower prices shift it rightward. -
The characteristics of AS
How does a change in the quantity of labour affect the LRAS curve?
Show the answer
An increase in the quantity of labour shifts the LRAS curve rightward; a decrease shifts it leftward. -
Short-run AS
If a country relies heavily on imported oil and its currency depreciates, what would happen to SRAS?
Show the answer
SRAS would decrease because the domestic currency cost of imported oil rises, increasing firms' production costs.
Paper 2, Paper 3
National Income
112 questions in the guide, across 9 subtopics. More from this topic
-
The circular flow of income
What are injections in the context of the circular flow of income?
Show the answer
Injections are additions to the circular flow of income that increase the total level of spending in the economy. -
The distinction between income and wealth
What is the key distinction between income and wealth?
Show the answer
Income is a flow measured over a period of time, while wealth is a stock measured at a single point in time. -
Injections, withdrawals and the equilibrium condition
Explain the mechanism by which an excess of injections over withdrawals causes economic expansion.
Show the answer
When injections exceed withdrawals, more spending enters the circular flow than leaves it, increasing total demand and causing national income to rise.
Paper 2, Paper 3
Economic Growth
98 questions in the guide, across 7 subtopics. More from this topic
-
What causes economic growth
How does an increase in enterprise contribute to economic growth?
Show the answer

What causes economic growth
How does an increase in government spending contribute to economic growth?
Show the answer
Higher government expenditure raises aggregate demand, leading to increased output and employment. -
Actual against potential growth, and export-led growth
Can an economy experience potential growth without experiencing actual growth? Explain how this is possible.

Fiscal policy: spending, taxation and the budget
What is a government budget deficit?
Show the answer
When government spending exceeds tax revenue in a given time period.
Paper 1, Paper 3
Business Growth
87 questions in the guide, across 6 subtopics. More from this topic
-
Why firms stay small and why they grow
Why do some service-based firms find it difficult to scale up?
Show the answer
The nature of their product or service requires personalised delivery that does not scale easily, limiting growth potential. -
Why firms stay small and why they grow
Why might a firm diversify into different products or markets?
Show the answer
Diversification spreads risk, so poor performance in one area can be offset by success in another. -
The principal-agent problem and types of organisation
State three methods used to reduce the principal-agent problem.
Show the answer
Performance-related pay, share options, and monitoring by non-executive directors.
Paper 1, Paper 3
Business Objectives
22 questions in the guide, across 2 subtopics. More from this topic
-
Profit, revenue and sales maximisation, and satisficing
Explain why total revenue is maximised when MR = 0.
Show the answer
At this output, total revenue is at its maximum because any additional unit sold would reduce total revenue (MR would become negative). -
Profit, revenue and sales maximisation, and satisficing
Why might a firm pursue revenue maximisation as its objective?
Show the answer
To increase market share, achieve economies of scale, or because managers are rewarded based on sales. -
Business objectives on a cost and revenue diagram
If a firm's MR curve has not yet reached the horizontal axis, what does this indicate about its current output relative to revenue maximisation?
Show the answer
The firm is producing below the revenue-maximising output; it could increase total revenue by expanding output until MR = 0.
Paper 1, Paper 3
Revenues, Costs and Profits
119 questions in the guide, across 9 subtopics. More from this topic

Revenue, elasticity and the revenue-maximising output
What is the effect on total revenue of a price change when demand is unit elastic?
Show the answer
Total revenue remains unchanged. -
Total, fixed, variable, average and marginal cost
What does each term in the formula ATC = TC ÷ Q represent?
Show the answer
ATC is average total cost, TC is total cost, and Q is the quantity of output produced.
Paper 1, Paper 3
Market Structures
235 questions in the guide, across 17 subtopics. More from this topic
-
Efficiency
Define X-inefficiency.
Show the answer
X-inefficiency occurs when a firm fails to minimise its costs of production due to lack of competitive pressure, resulting in actual costs exceeding the minimum possible costs. -
Perfect competition: equilibrium and efficiency
State the full equilibrium condition showing the relationship between MC, MR, AR and ATC in long-run equilibrium for a perfectly competitive firm.
Show the answer
MC = MR = AR = ATC at the equilibrium output. -
Monopolistic competition: short-run and long-run equilibrium
Why does the entry of new firms occur when existing firms earn supernormal profits?
Show the answer
Because low barriers to entry allow new firms to enter and capture some of the available profits.
Paper 1, Paper 3
The Labour Market
91 questions in the guide, across 7 subtopics. More from this topic
-
Demand for labour
If capital and labour are complementary factors, what happens to labour demand when a firm increases its capital investment?
Show the answer
The demand for labour rises, because complementary factors are used together and more capital requires more workers to operate it effectively. -
Demand for labour
What typically happens to labour demand during a recession?
Show the answer
Labour demand falls as reduced economic activity and lower consumer spending mean firms need fewer workers. -
What determines the supply of labour
How do promotion opportunities affect the supply of labour to an occupation?
Show the answer
Better opportunities for career advancement and promotion attract more workers to an occupation, as they value the prospect of future progression and higher earnings.
Paper 1, Paper 3
Government Intervention in Markets
41 questions in the guide, across 3 subtopics. More from this topic
-
Controlling mergers, and price, profit and quality regulation
What does it mean when a merger is approved with conditions?
Show the answer
The merger can proceed but with requirements attached, such as divestment of certain assets, to address competition concerns. -
Controlling mergers, and price, profit and quality regulation
Why might profit regulation reduce productive efficiency in monopoly firms?
Show the answer
It may reduce incentives for cost efficiency if firms are guaranteed a certain profit level regardless of their performance. -
Deregulation, tendering, privatisation and nationalisation
What benefits can competitive tendering bring to government and public services?
Show the answer
It can reduce costs to government and improve service quality by selecting the most efficient provider.

Show the answer
The headcount ratio measures absolute poverty as the percentage of the population living below the absolute poverty line. -
Absolute and relative poverty
Why does unemployment increase both absolute and relative poverty?
Show the answer
Households lose their primary source of income, causing them to fall below both the fixed threshold for basic necessities and the relative threshold compared to median income. -
Measuring inequality: the Lorenz curve and Gini coefficient
What is the Gini coefficient?
Show the answer
A numerical measure of inequality derived from the Lorenz curve, calculated as the ratio of the area between the line of equality and the Lorenz curve to the total area under the line of equality.

The effects of public expenditure, and crowding out
How can progressive taxation combined with transfer payments reduce income inequality?
Show the answer
By redistributing income from higher to lower income groups through taxing the wealthy more heavily and providing benefits to those on lower incomes. -
The Laffer curve and the effects of tax changes
Why do regressive indirect taxes tend to increase income inequality?
