Text A — Overview of Mexico
- Mexico, with its abundant natural resources, is the second largest economy in Latin America. However, compared to other Latin American countries, Mexico has underperformed. Its annual economic growth rate averaged 2.5% between 1994 and 2019. Per capita income rose more slowly, at an average rate of less than 1% annually.
- Government expenditure has been rising, while taxation revenue has been stable or falling. Therefore, there is concern about the increasing government debt. If there is a recession, automatic stabilizers will increase the budget deficit, further raising the level of government debt. However, the International Monetary Fund (IMF) forecasts that government debt will stabilize in the mid-2020s, at around 65 % of gross domestic product (GDP).
- The oil sector makes an important contribution to Mexico’s economy. Earnings from this sector were about 30 % of total government revenue in 2019. However, as countries increase their use of alternative energy sources, the long-term trend of falling oil prices will probably continue.

- Since 1994, the exchange rate for the peso (Mexico’s currency) has been floating. In March 2020, the rate changed from 18 pesos per United States (US) dollar to 25 pesos per US dollar. During 2020, the deficit on the balance of trade in goods continued to widen. However, by April 2021 the trade balance had changed to a surplus as exports of manufactured goods rose strongly. The deficit on the current account has also been narrowed by rising net remittances.
Text B — Free trade agreements
- The North American Free Trade Agreement (NAFTA) was a three-country accord negotiated by the governments of Canada, Mexico, and the United States that entered into force in January 1994. NAFTA eliminated most tariffs on products traded between the three countries, with a major focus on liberalizing trade in agriculture, textiles, and automobile manufacturing. The deal also sought to protect intellectual property, establish dispute resolution mechanisms, and through side agreements, implement labor and environmental safeguards. Trade among the NAFTA members tripled over the following 25 years, partly due to trade disputes between the US and China.
- Following the establishment of NAFTA, productivity increased in Mexico. US and Canadian firms viewed Mexico as a low-cost location for factories, which could improve their competitiveness. Therefore, foreign direct investment (FDI) into Mexico grew significantly throughout the 1990s and early 2000s. In the industrial north of Mexico, high-tech manufacturing factories were established and wages increased. However, the agricultural south did not benefit from the FDI. Agricultural exports from Mexico did increase, but Mexican farmers, especially corn producers, faced competition from subsidized US agriculture.
- The wage differential between the US and Mexico was predicted to decrease significantly, but a large wage gap remains. NAFTA’s effect on employment has been mixed. Some workers became unemployed when their firms lost market share due to increased competition, while others gained from the creation of new market opportunities.
- In 2020, NAFTA was renegotiated as the US–Mexico–Canada Agreement, which kept elements of NAFTA, while adding provisions regarding digital trade and financial services. The requirement that a high proportion of the inputs used in exported goods must come from member countries may mean that the cheapest inputs cannot be used. There are also additional rules to protect the environment and support labour rights. For example, 40 % of the value of the components in each vehicle exported from Mexico must come from factories paying a wage of at least US$16 per hour. As a result, the incomes of Mexicans who find industrial employment are raised.
Text C — Access to banking and finance in rural areas
- The persistence of income inequality in Mexico is partly due to domestic factors, such as underdeveloped financial institutions and low productivity in the large informal sector. Improving access to banking and finance could significantly benefit low-income households and small firms.
- The Expanding Rural Finance Project aims to provide finance for women, young people, and small firms in rural areas where there are no commercial banks. Over 170 000 loans (averaging US$1850 per loan) were provided from 2016 to 2020. Among the recipients, 76 % lived in rural areas and 81% were women.

List two functions of the International Monetary Fund (IMF) (Text A, paragraph 2).
[2]
Few candidates had knowledge of IMF functions, providing vague answers or listing functions relating to the World Bank and occasionally the WTO.

Define the term remittances indicated in bold in the text (Text A, paragraph 5).
[2]
Almost all the students were able to answer this question correctly.

Using information from Table 1 and Table 2, calculate the value of Mexico’s gross domestic product (GDP) (in US$) in 2019.
[2]
10267 x 128
Any valid working should be rewarded with [1]
1 314 176 million or 1 314 176 000 000 or 1.31 trillion or 1314.18 billion or accept scientific notation 1.314176 x 10¹²
An answer of 1 314 176 without workings or without units, is sufficient for [1]
This was a simple calculation which students had little difficulty answering correctly.

Sketch a minimum wage diagram to show the possible effect of a minimum wage on unemployment in Mexico (Text A, paragraph 4).
[3]
Candidates who incorrectly label diagrams can be awarded a maximum of [2]
The vertical axis may be (real) wage (rate) or price of labour. The horizontal axis may be Quantity, Q, Q of labour or labour or number of workers, employment. All abbreviations are acceptable.
The unemployment/excess supply of labour/surplus can be illustrated by referring to Q1Q2, NsNd, QsQd, or by annotating the diagram (for example showing the surplus). A title is not necessary.
Alternatively, a diagram may show two minimum wage lines. If labelled appropriately, it can be fully rewarded.
Most candidates correctly constructed the minimum wage diagram although a significant minority failed to identify the possible effect on employment in the diagram. Most candidates accompanied the diagram with an explanation, sometimes at length. It should be emphasised that an explanation is not required and uses up valuable time that could have been spent on other questions.
Using a business cycle diagram, explain how automatic stabilizers will affect the decrease in real GDP that occurs during a recession (Text A, paragraph 2).
[4]
Candidates who incorrectly label diagrams can be awarded a maximum of [3].
The horizontal axis may be time or years. The vertical axis may be real GDP or economic activity. The peaks and troughs etc. do not need to be labelled. All abbreviations are acceptable. A title is not necessary.
Alternatively, the diagram may also show the peaks being dampened and/or the trend line.
The majority of students constructed the standard business cycle diagram, but few included the impact of automatic stabilizers. Too often the explanation lacked examples of automatic stabilizers, or a complete explanation of how automatic stabilizers might mitigate the effects of a recession. Candidates seemed to have difficulty in explaining that stabilizers resulted in real GDP being higher than it would otherwise have been.


Using a demand and supply diagram, explain why the price of oil will probably continue to fall (Text A, paragraph 3).
[4]
Candidates who incorrectly label diagrams can be awarded a maximum of [3].
The vertical axis may be price or P. The horizontal axis may be quantity or Q. A title is not necessary.
This was generally quite well answered. Most students used the text to identify ''increase their use of alternative energy" to explain how this might lead to a continued fall in oil prices.


Using a J-curve diagram, explain the likely reason why the change in the exchange rate for the peso initially caused the deficit on the balance of trade to widen and then eventually led to a surplus (Text A, paragraph 5).
[4]
NB An alternative correct explanation could be that, in the short run, contracts cannot be rewritten (or similar) and therefore the volumes of exports and imports do not adjust completely to the new prices leading to increased deficit [1], but in the long run, the consumers adjust more, leading to an improvement/surplus in the balance of trade [1].
Candidates who incorrectly label diagrams can be awarded a maximum of [3].
The horizontal axis may be time or years or months. The vertical axis may be current/trade balance or current/trade account /X-M All abbreviations are acceptable. A title is not necessary.
The majority of candidates produced a well labelled J-curve diagram, but a significant number demonstrated partial understanding in their explanation. Better answers effectively used the MarshallLerner condition in their explanation. Some students did not indicate surplus or deficit as part of the y-axis labelling.

Using a poverty cycle diagram, explain how the Expanding Rural Finance Project raises incomes in rural areas (Text C).
[4]
Candidates who incorrectly label diagrams can be awarded a maximum of [3].
Almost all the candidates were able to explain how increased access to finance can help break the poverty cycle, but a few lost a mark for not drawing the poverty cycle diagram correctly.


Using information from the text/data and your knowledge of economics, discuss the costs and benefits for Mexico of participation in the free trade agreement with the US and Canada.
[15]
“Discuss” requires candidates to offer a considered and balanced review that includes a range of arguments, factors or hypotheses. Opinions or conclusions should be presented clearly and supported by appropriate evidence.
Answers may include:
- a definition of a free trade agreement/area
- a tariff diagram
- an AD/AS diagram
- a PPC diagram
- a diagram showing comparative advantage for two different goods
- a diagram showing a subsidy for US corn producers.
Possible costs of participation in an FTA:
- trade diversion (Text B, paragraph 1 or 4)
- inequality between the manufacturing north (urban areas) and the agricultural south (rural areas) probably widening (Text B, paragraph 2; Text C)
- some sectors cannot compete with (subsidized) imports leading to job losses (Text B, paragraphs 2 or 3)
- US/Canadian companies setting up factories in Mexico may lead to exploitation of workers and/or the environment (Text B, paragraph 2 or 3)
- profits from the factories will be sent back to the US/Canada leading to an outflow on the current account, which is already in deficit (Text A paragraph 5; Text B, paragraph 2 or 3; Table 1)
- rules will prevent Mexico from getting the cheapest inputs (Text B, paragraph 4)
- informal sector unlikely to gain from free trade (Text C, paragraph 1).
Possible benefits of participation in an FTA:
- trade creation, which may improve the growth rate of GDP (Text A, paragraph 1;
- Text B, paragraph 1 or 3; Table 1)
- lower tariffs on imports and stimulus to efficiency lead to higher productivity and lower prices (Text B, paragraph 2)
- Mexico can gain a surplus on the Balance of Trade (Text A, paragraph 5; Table 1)
- more inward FDI (Text B, paragraph 2; Table 1)
- higher wages (above the minimum wages) for those working in manufacturing firms that export to US/Canada (Text B, paragraph 4)
- changes in HDI and Gini coefficient indicate an improvement in the standard of living and less inequality, which may be due to the FTA (Table 2)
- rules to protect the environment leading to more sustainable growth and development (Text B, paragraph 1 or 4)
- Mexico is able to increase exports of goods other than oil to reduce dependence
- on oil (diversification is enabled) (Text A, paragraph 3).
Examiners should be aware that candidates may take a different approach which, if appropriate, should be rewarded.
The quality of answers to this question varied. Good answers were able to use the text effectively and integrate the data with economic theory.
There was generally a basic understanding of the question but too often responses tended to be generic. Better answers effectively used economic theory and terminology coupled with appropriate diagrams in their analysis. Too many responses, however, were descriptive or simply outlined the costs and benefits of free trade with limited focus on the question. For example, students would write "trade diversion" or "trade creation" without explaining what is meant in the context of the question. While judgements were made, evaluation tended to be superficial.
It should be noted that reference to diagrams in previous questions is acceptable.
