Question
Will stronger economic growth in the United States (US) lead to high inflation? The US has experienced stronger economic growth than countries in Europe and elsewhere since the COVID-19 pandemic. In terms of Gross Domestic Product (GDP), it had particularly strong growth over the fourth quarter of 2023 of 3.3%. This far exceeded economists’ expectations of 2%. This means that annual growth for 2023 was 2.5% which was better than other high-income economies. It is on target to do the same in 2024 as shown in Fig 1.1. 2.5% 2.0% % change 1.5% in real GDP per year 1.0% 0.5% 0.0% US Eurozone Japan UK Canada key 2023 2024 Fig. 1 International Monetary Fund (IMF) economic growth forecasts for 2023 and 2024 Economists have suggested that the strong economic growth in the US was caused by both demand and supply factors. In 2020, the US government responded to the COVID-19 pandemic by injecting US$5 trillion into the economy. Spending in many areas included more generous unemployment benefits and grants to small firms. This huge financial stimulus, much bigger than other countries, has been credited with maintaining consumer spending which represents 70% of aggregate demand. On the supply side of the economy, existing flexible labour markets enabled firms to make workers redundant. This encouraged firms to invest in new technologies, leading to increased productivity and continued expansion in the long run. As firms expanded, they employed more workers causing disposable incomes to rise. Finally, the US is a net exporter of energy and therefore firms did not suffer the huge increase in energy costs faced by firms in Europe caused by the conflict in Ukraine. This has allowed the US to keep inflationary pressure under control. In March 2024, however, the rate of inflation in the US rose much faster than expected as its level of unemployment fell, leading to an increase in consumer spending. Although this may lead to further economic growth and the benefits this brings, there are costs associated with inflation that may need to be dealt with. One policy that could be used is to increase interest rates, but US interest rates were already at their highest level for more than two decades because of earlier inflationary pressures. The hope had been that interest rates might start to fall, but now there are fears that any cuts in interest rates will be delayed or even worse, it might even be necessary to increase them further.

Mark scheme
1(a) Compare the forecast rates of economic growth for the US and 2 Eurozone between 2023 and 2024. • The forecasts for both the US and Eurozone have shown real economic growth between 2023 and 2024 • The forecast for the US has shown higher real economic growth than the Eurozone in both periods. • The forecast for the US has shown a fall in the rate of growth between 2023 and 2024 whereas the forecast for the Eurozone has shown an increase. Guidance: Only award marks for a valid comparison between the two years and the two economies. Note: answers which suggest GDP in the US has fallen between 2023 and 2024 must not be credited as it is the rate of growth that has fallen. 1(b) Explain one reason why the IMF uses percentage change in real GDP 2 and not percentage change in nominal GDP when measuring economic growth. • Nominal GDP growth shows the growth without taking into account inflation whereas real GDP growth removes the effects of inflation. (1) • It allows for a better / more meaningful comparison between years. (1) Note: do not award the 2nd mark without some understanding of the two terms in the question. 1(c) Explain, with the help of a diagram, why an increase in productivity in 4 US firms may reduce the price of their products and consider whether this will always be the outcome. • An increase in productivity suggests production is more efficient and will reduce costs. (1) • This should have the effect of shifting the supply curve to the right as shown on an accurately labeled diagram. (1) • The fall in price should be shown on the diagram, e.g., by an arrow or P1 P2, and linked to the increase in productivity. (1) For evaluation 1 mark maximum: An assessment why the price may not fall, e.g., because businesses decide not to pass the fall in potential price on to consumers and include the extra profit in their costs meaning the supply curve does not shift to the right or other costs increase to offset the improvement in productivity; due to perfectly elastic demand. (1) 1(d) Assess whether the costs of inflation are always likely to be greater than 6 the benefits of inflation for the US. Up to 4 marks MAX for analysis of both benefits and costs Up to 3 marks for analysis of the possible benefits of inflation, e.g., it may be a sign of economic growth and may encourage businesses to produce more and therefore reduce levels of unemployment etc. if the inflation rate is low and stable. Also, borrowers may gain. Up to 3 marks for analysis of the possible costs of inflation, e.g., menu and shoe leather costs, lenders may lose, fiscal drag, reduced international competitiveness etc., if the inflation rate is high or becomes prolonged . This may result in reduced investment due to uncertainty. Up to 2 marks for evaluation of positive and negative effects , e.g., it will depend on the level of inflation and whether it is likely to be prolonged. It also may depend on the rate of inflation in other countries. Reserve 1 mark for a justified conclusion. Note: evaluation should be in the context of the US to gain any credit. For example, the data suggests that inflation in the US is largely the result of rising AD and less due to rising costs of production. Any valid evaluation must reflect this. 1(e) Assess the extent to which maintaining interest rates at a high level will 6 be the best policy for the US to control inflation. Up to 4 marks MAX for analysis of both advantages and disadvantages Up to 3 marks for analysis of the possible advantages of maintaining interest rates at a high level, e.g., it is a contractionary demand policy that will reduce AD by reducing consumer expenditure and investment. This should lower inflationary pressure and keep inflation rates lower. Up to 3 marks for analysis of the possible disadvantages, e.g., it may reduce economic growth and increase unemployment if the policy is maintained for a long period of time. It may reduce international competitiveness if it leads to an increase in exchange rates. It may also not be appropriate if the cause of inflation is due to cost push factors, Up to 2 marks for evaluation of the advantages and disadvantages of maintaining interest rates at a high level to control inflation in the US. This may also include an assessment (although this is not essential) of other policies such as supply-side policy may be less damaging and fiscal policy. It also depends on the timescale. Reserve 1 mark for a justified conclusion. Note: evaluation should be in the context of the US to gain any credit. For example, the data suggests that inflation in the US is largely the result of rising AD and less rising costs of production. Any valid evaluation must reflect this. EITHER
