CAIE A-Level Economics 4.4 Economic Growth Question Bank

The COVID-19 pandemic had a very significant impact on the global economy in 2020. Negative economic growth rates were recorded for all major economies. The speed, unexpected and unprecedented nature of the downturns has been devastating for businesses, governments and populations. Individual economies reacted to the pandemic differently. Fig. 1.1 shows quarterly economic growth rates in 2020 for four selected countries compared to the OECD (Organisation for Economic Co-operation and Development) average.

China's economic performance in 2020 was the exception. China was the first country to experience the pandemic. It has also been the first economy to recover from recession, a period of two consecutive quarters of negative economic growth. The Chinese government was quick to enforce lockdowns to limit the pandemic and there was rapidly increasing demand for exports of PPE (personal protection equipment) and other Chinese-made products.

The case of neighbouring South Korea was different. Like China, the impact of the pandemic was more effectively contained than in other economies and growth in South Korea's economy was less affected. There was, however, little evidence in the data that by the end of 2020, South Korea's economy would recover to its pre-2019 position of strong economic growth.

The economies of the US and the UK had negative quarterly economic growth throughout 2020. Economists in these countries have disagreed about how best to increase the rate of economic growth after the pandemic. The governments of both countries introduced very high government spending programmes to encourage the return to economic growth in 2021. However, monetary policies have been widely promoted by many economists as an alternative to more traditional fiscal measures.

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.

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.
