Same stage of production / both in the tertiary (service) sector / same sector (1) same industry / same product / same service (1) can increase market share (1). 1(d) Explain two reasons why a large US commercial bank 4 One mark for each of two reasons identified and one mark may charge a high price for its services. for each explanation. Logical explanation which might include: High spending on opening new branches / advertising campaigns / developing online banking (1) need to get back costs / make a profit / may experience diseconomies of scale (1). May offer high quality services (1) have high demand / customers willing to pay a high price (1). High degree of monopoly / market power / control 32% of market (1) customers may have brand loyalty / reluctant to switch banks / lack of substitutes / inelastic demand / can charge high prices to earn high profits/raise total revenue / be a price maker (1). High incomes in the US (1) many customers have the ability to pay a high price (1). Employ skilled / well educated workers (1) so may pay high wages / may have high costs of production (1). 1(e) Analyse how an increase in unemployment may affect 4 the Nigerian government’s budget. Coherent analysis which might include: Likely to increase a deficit / reduce a surplus / may result in a budget deficit (1). Tax revenue likely to fall / budget likely to fall (1) due to lower incomes (1) less income tax revenue (1) lower profits (1) less corporation tax revenue (1) lower spending (1) less indirect tax revenue (1) government may cut taxes to reduce unemployment (1). Government spending likely to rise (1) more spending on e.g. benefits / subsidies to the poor / law and order/ healthcare (1) may be more spending on measures to reduce unemployment / expansionary fiscal policy (1) may spend less on other areas e.g. education (1). 1(f) Analyse the relationship between countries’ average 5 No marks for just stating what the figures are e.g. Germany years of schooling and birth rates. has 15 years of schooling and a birth rate of approximately 8. US has 14 years of schooling and a birth rate of Coherent analysis which might include: approximately 12. Argentina has 11 years of schooling and Overview a birth rate of approximately 16 etc. Generally, an inverse relationship / the more years of schooling, the lower the birth rate / the fewer years of schooling, the higher the birth rate (1). Supporting evidence Up to 2 marks maximum for two pieces of relevant supporting evidence e.g.: • Germany has the highest years of schooling and lowest birth rate (1) • Chad has lowest years of schooling and highest birth rate (1) • US has more years of schooling than Argentina and so a lower birth rate (1) • the three countries with three highest years of schooling have the three lowest birth rates (1). Exception Nigeria / Eritrea (1) Nigeria has more years of schooling than Eritrea but a higher birth rate (1). Comments More years of schooling is likely to cause people to form partnerships / have children later / focus on careers / increase awareness of contraception/family planning / increase health / reduce size of families (1) increase cost of raising children / having more children may reduce the ability of families to keep their children in education for many years / exception may be result of other influences e.g. differences in fertility rates / differences in social attitudes (1). 1(g) Discuss whether or not a subsidy, given to farmers by 6 Apply this example to all questions with the command the Nigerian government, would reduce the deficit on word DISCUSS the current account of its balance of payments.

It will encourage supply to extend (1) a surplus may develop (1). There may be an illegal market in chocolate (1). There may be a cost to the government (1) it may have to pay to monitor that the price is being charged (1) lower tax revenue from chocolate (1) may be an increase in unemployment (1). 1(h) Demand may be inelastic (1) resulting in a relatively small fall in demand / chocolate may be addictive (1). It depends on how high the minimum price is (1) may have no effect if set below the market equilibrium (1).
Q2 · The economic problem results in choices and opportunity cost
2 The economic problem results in choices and opportunity cost. People have to decide what job to do and where to live. In recent years Australia has recruited teachers from a number of countries including Canada, the UK and the US. Most of these teachers specialise in a single subject. (a) Define opportunity cost. [2] (b) Explain the economic problem and why it is always likely to exist. [4] (c) Analyse why the wages of all teachers may increase. [6] (d) Discuss whether or not a teacher would benefit from specialisation. [8]
Mark scheme: 2(a) Define opportunity cost. 2 The (next) best alternative / choice (1) forgone / sacrificed (1). 2(b) Explain the economic problem and why it is always 4 likely to exist. Logical explanation which might include: The economic problem is finite / limited resources (1) and infinite / unlimited wants / wants exceed resources (1) scarcity (1). It is always likely to exist as wants grow faster than resources / wants are increasing (1) there will never be enough resources to produce all the products people would like to have (1). People are living longer / population is increasing (1) more resources are needed / some resources are being depleted (1). 2(c) Analyse why the wages of all teachers may increase. 6 Coherent analysis which might include: The wages of teachers may increase if demand for teachers rises (1) derived (1) this may be because there are more children to educate / rise in population size (1) smaller class sizes / children staying in education longer (1) teachers being more productive / skilful (1). A decrease in supply will increase wages (1) this may be due to a rise in qualifications needed (1) long period of training (1) rise in wages in other occupations / need to compete with other occupations (1) need to compete with wages paid to teachers in other countries / recruit from higher paying countries (1). Bargaining power of teachers may increase (1) more teachers may belong to trade unions (1) may be more prepared to take strike action (1) wages may be raised to keep up with inflation / maintain real wages (1). Government policy may favour teachers (1) e.g. there may be an increase in school leaving age / increase provision of education (1). Increase in minimum wage (1). 2(d) Discuss whether or not a teacher would benefit from 8 Level Description Marks specialisation. 3 A reasoned discussion which 6–8 In assessing each answer, use the table opposite. accurately examines both sides of the economic argument, making use of Why it might: economic information and clear and • may be trained more quickly logical analysis to evaluate economic • become more skilled / productive issues and situations.

Q3 · In 2019, Russia had an unemployment rate of 4.6%
3 In 2019, Russia had an unemployment rate of 4.6%. Russia experienced full employment in the past. Its government wants unemployment to be lower. In 2018, the Russian government cut its spending which may have increased poverty. In both 2018 and 2019, the government did not change its income tax rate. Russia operates a proportional tax rate system. (a) Define full employment. [2] (b) Explain the difference between a proportional income tax system and a progressive income tax system. [4] (c) Analyse why a cut in government spending might increase poverty. [6] (d) Discuss whether or not a fall in a country’s unemployment rate always benefits workers. [8]
Mark scheme: 3(a) Define full employment. 2 One mark for idea of full employment of resources e.g. all workers in employment. The lowest unemployment possible (very low percentage) / job vacancies matching the number unemployed (2). Low unemployment (1). May still be some workers in between jobs / some frictional unemployment (1). Zero unemployment (1). 3(b) Explain the difference between a proportional income 4 Three marks maximum for proportional income tax system tax system and a progressive income tax system. and three marks maximum for progressive income tax system. Logical explanation which might include: Proportional income tax system takes the same percentage / proportion of income (1) from all income groups (1). In a proportional income tax rate system, the tax rate does not change (1) as income changes (1) has no effect on the distribution of income (1). Progressive income tax system takes a larger percentage / smaller percentage (1) of the income of the rich / the poor / places a larger burden on the rich (1) helps redistribute income from the rich to the poor / reduces the gap between rich and poor / may be used to promote equity (1). In a progressive income tax rate system, the tax rate increases (1) as income increases (1). 3(c) Analyse why a cut in government spending might 6 increase poverty. Coherent analysis which might include: A cut in government spending might reduce total demand (1) increasing unemployment (1) reducing incomes (1). Government spending on subsidies to firms might be reduced (1) which may raise prices (1). Government spending on education might be reduced (1) this might cause a decrease in skills (1) reducing wages (1) may lead to vicious cycle of poverty (1). Government spending on healthcare might be reduced (1) lowering productivity and wages (1). Government spending on state / unemployment benefits might be reduced (1) reducing goods and services that can be bought (1). Government spending on state pensions might be reduced (1) the old may not be able to buy basic necessities (1). 3(d) Discuss whether or not a fall in a country’s 8 Level Description Marks unemployment rate always benefits workers. 3 A reasoned discussion which 6–8 In assessing each answer, use the table opposite. accurately examines both sides of the economic argument, making use of Why it might be: economic information and clear and • increase choice of jobs logical analysis to evaluate economic • increase wages issues and situations.

Q4 · Advances in technology have changed how trees (wood) are cut down, transported and used…
4 Advances in technology have changed how trees (wood) are cut down, transported and used in the manufacture of furniture, such as tables. Wood is in inelastic supply. Wood can be supplied in all economic systems. However, public goods are not supplied in a market economic system. (a) Define inelastic supply. [2] (b) Explain why public goods would not be supplied in a market economic system. [4] (c) Analyse, using a demand and supply diagram, the effect on the market for furniture of an increase in the price of wood. [6] (d) Discuss whether or not advances in technology will benefit a country’s population. [8]
Mark scheme: 4(a) Define inelastic supply. 2 Allow one mark for PES = 0. Quantity supplied / supply changes by a smaller percentage change than price (2). Supply changing by less than price / PES less than 1 / PES < 1 / supply unresponsive to change in price (1). 4(b) Explain why public goods would not be supplied in a 4 No marks for examples. market economic system. Logical explanation which might include: Public goods are non-excludable (1) it is not possible to stop people who are not prepared to pay for them, from consuming them (1) free rider problem (1). Public goods are non-rival (1) if supplied for one, supplied for everyone and so cannot charge additional consumers (1). Private sector firms are profit motivated (1) they will not produce products if they cannot get revenue from them (1) would make a loss (1). 4(c) Analyse, using a demand and supply diagram, the 6 effect on the market for furniture of an increase in the price of wood.

Q5 · While 15% of US exports go to Mexico, 80% of Mexico’s exports go to the US
5 While 15% of US exports go to Mexico, 80% of Mexico’s exports go to the US. In 2019, the US government imposed some methods of protection to reduce imports from Mexico. This US action caused a fall in Mexico’s foreign exchange rate. Despite a rise in its inflation rate, Mexico’s central bank reduced the rate of interest from 7.75% at the end of 2019 to 6.5% in March 2020. (a) Identify two methods of protection. [2] (b) Explain two reasons why a government may want to reduce imports. [4] (c) Analyse how a fall in a country’s foreign exchange rate could increase its inflation rate. [6] (d) Discuss whether or not a decrease in the rate of interest will increase a country’s GDP. [8]

So, for improve balance of payments reason, there is a maximum of 2 marks. Logical explanation which might include: To improve the current account of the balance of payments (1) reduce a current account deficit (1) move from a deficit to a surplus / move to a balance / achieve balance of payments stability (1) increase net exports (1). To increase GDP / economic growth (1) switch demand from imports to domestically produced products / increase demand for domestically produced goods / protect domestic firms (1) allow infant industries to grow (1) Prevent dumping (1) the sale of goods from abroad at below cost / predatory prices (1). To increase employment / reduce unemployment (1) to raise living standards (1). To reduce dependence on other countries / make the country more independent (1) as risk of supplies being cut off / price being increased (1). To stop / reduce a fall in the exchange rate (1) less of the currency will be sold to buy imports (1). 5(c) Analyse how a fall in a country’s foreign exchange rate 6 could increase its inflation rate. Coherent analysis which might include: Raise import prices (1) increase price of imported raw materials / capital goods (1) increase costs of production (1) if demand is inelastic (1) cause cost-push inflation / imported inflation (1). Reduce export prices (1) increase demand for exports (1) increase export revenue if demand is elastic (1) switch demand for imports to domestic products (1) increase total demand (1) cause demand-pull inflation (1). 5(d) Discuss whether or not a decrease in the rate of interest 8 Level Description Marks will increase a country’s GDP. 3 A reasoned discussion which 6–8 In assessing each answer, use the table opposite. accurately examines both sides of the economic argument, making use of Why it might: economic information and clear and • reduce saving logical analysis to evaluate economic • increase borrowing issues and situations.
