Text D - Overview of Papua New Guinea

(1) Papua New Guinea (PNG) consists of hundreds of small islands near Australia. Over 50 % of the labour force is employed in agriculture, forestry and fishing. The extraction sector, which mines non-renewable minerals (gold and copper) and extracts energy products (oil and gas), provides 30 % of the gross domestic product (GDP). The mining operations sometimes cause environmental damage and disputes over land rights.

(2) The lack of substitutes and the difficulty of extracting gold, copper and gas cause both global demand and supply to be price inelastic. Consequently, changes in global demand result in volatile prices, which lead to macroeconomic instability because the extraction sector in PNG is so large. Fiscal policies have been unable to reduce the business cycle fluctuations. Tax revenue has declined as a percentage of GDP partly due to lower commodity prices and thus business tax revenue. The government could get more revenue from the extraction sector through ownership or part-ownership of the firms. However, such revenues are unpredictable and probably unsustainable.

(3) After the rapid depreciation of the kina (PGK), PNG's currency, between 2012 and 2015, the central bank moved away from a floating exchange rate system to a managed exchange rate system. It used reserve assets in the foreign exchange market to prevent excessive currency depreciation, thereby lowering cost-push inflationary pressures. However, this intervention caused the PGK to become an overvalued currency. Therefore, the International Monetary Fund (IMF) recommended less intervention in the foreign exchange market so the PGK would gradually depreciate.

(4) Official development assistance (ODA) is providing funds and technical assistance to improve infrastructure and therefore assist economic growth. The World Bank's aid programme provides advice and funds for investment in human capital, especially for women and children's education. The government provides subsidies for schools to correct the welfare loss that occurs in the education market, but they are inadequate.
Text E - Papua New Guinea's balance of trade and trade strategies

(1) The surplus on PNG's balance of trade in goods is due to the extraction sector, which earns 90 % of its export revenues. When global commodity prices were high, exports generated growth. Less than 10 % of export revenues come from agriculture, forestry and fishing, although these sectors employ more people. Over 85 % of PNG's exports go to just five countries. Studies show that PNG exports have a high income elasticity of demand (YED =+3.0 ), but price elasticities of demand are low, particularly for mineral exports such as copper (PED =-0.18 ).

(2) PNG has been attempting various trade strategies, including export promotion, import substitution and economic integration. PNG has relatively low tariffs on most imports. However, tariffs on manufactured items, including machinery for palm oil production, were increased in 2019 to protect local manufacturing companies. Unfortunately, the tariffs on machinery harmed some exporting industries by raising production costs. Additionally, there are restrictions on the exports of some primary goods. For example, exports of logs are restricted in order to encourage timber processing within PNG. However, the tax on log exports caused some logging companies to close down.

(3) PNG has large trade surpluses (based on gas, minerals, and timber exports) with Australia and China, but it wants to diversify and promote agricultural exports. Therefore, it is now negotiating free trade agreements with both countries.

(4) The overall trade surplus will possibly decrease. Exports of gold and copper are not growing strongly. The main agricultural and forestry exports are palm oil, coffee, cocoa and timber, but PNG's shares in the global markets for these items have declined. PNG's vulnerability to climate change is particularly concerning, due to its need to promote agriculture for future export growth and to raise rural incomes.
Text F - Foreign direct investment and Papua New Guinea

(1) The capital and financial accounts on the balance of payments have large deficits. The outflows are mainly due to the repayment of loans that were used to develop the extraction sector. Most inward foreign direct investment (FDI) has been for mining and energy extraction projects. The FDI inflows fall once the project is completed.

(2) PNG is setting up special economic zones in certain regions, which provide tax exemptions and eased regulations. The aim is to encourage FDI into tourism and industries that process agricultural and fishing products. Aid agencies recommend using FDI for renewable energy and environmental projects.

Text A - Overview of the economy and government policies in Kenya

Read the extracts and answer the questions that follow.
Text A - Overview of the economy and government policies in Kenya

(1) Kenya, in East Africa, is achieving high annual economic growth rates, averaging above 5 %. Living standards are improving and employment is increasing in the manufacturing, tourism, construction and education sectors. Kenya's high growth is also changing the distribution of income and affecting the environment. However, climate change and high levels of inequality may reduce future growth rates.

(2) Floods and droughts are severe and frequent. In 2022-2023, droughts caused agricultural output to fall, affecting the employment of 40 % of the population and doubling the number of people with insufficient food. The government took measures to increase food supplies, such as reducing the tariff on imports of rice.

(3) The rising price of food is the main cause of inflation in Kenya. The central bank used a contractionary monetary policy in 2022 and 2023 to reduce inflation and to prevent the depreciation of the country's currency (Kenyan shilling, KES).

(4) The budget deficit as a percentage of gross domestic product (GDP) became smaller in 2023 because government expenditure grew more slowly than GDP. Moreover, economic growth resulted in higher tax revenue from both income tax and a 16 % indirect tax on goods and services. The government is also receiving revenue from the sale of some state-owned enterprises (SOEs). A World Bank programme, aimed at an expansion of "green" energy in Kenya, provides financial and technological support to the Kenya Power and Lighting Company, an SOE that has been making losses.

(5) The currency depreciation in 2022 boosted exports. Services, which are approximately 38 % of total exports and include tourism and financial services, are growing faster than exports of goods. Manufactured goods account for 37 % of total exports and agricultural goods account for 25 %. Revenue from exports of tea, flowers, vegetables, meat, and coffee are volatile and unpredictable. The droughts in 2022-2023 reduced output, which lowered export revenue from vegetables and flowers by almost 20 %.
Text B - Unequal distribution of the benefits of economic growth in Kenya

(1) Although economic growth has reduced absolute poverty, inequality remains a problem, particularly between the formal and informal sectors and between the urban and rural areas. Rural poverty is caused by low agricultural productivity and farmers' limited access to markets, finance, and technology.

(2) However, the level of education has improved significantly, with a literacy rate of over 90 %. Secondary school attendance rates have increased from 13 % in 2003 to 49 % in 2022, despite the costs of attending school. In 2022, the government introduced a fund (the Hustler Fund), partly financed by foreign aid. The fund provides low-interest loans to women, young people, and small firms, for education or investment.
Text C - Reducing and adapting to climate change in Kenya

(1) Global warming is affecting the Kenyan economy. Consequently, agricultural output and tourism, which account for 70 % of employment and most exports, will probably decline. Therefore, GDP could fall by 2 % annually. However, Kenya has relatively low carbon emissions, particularly because renewable resources generate 90 % of electricity, a figure that is planned to rise to 100 % by 2030.

(2) Measures taken by other economies to reduce carbon emissions provide opportunities for Kenya, because the markets for "green" goods are expanding. Kenya is able to sell tradable permits (carbon credits) to high-emitting countries due to its reforestation programmes. However, there are challenges for Kenya. The production of exports, such as coffee, needs to meet strict sustainability regulations imposed by the European Union (EU) on imports.

(3) The International Monetary Fund (IMF) recommends that climate-related considerations should be part of macroeconomic and infrastructure policies. It also recommends that carbon taxes should be imposed to reduce the use of fossil fuels by firms. Rapid urbanization is increasing the need for electric vehicles and improved public transport. Energy efficiency measures, fuel substitution, and switching to rail transport will not only lower transportation costs but also reduce the trade deficit. This is because fossil fuels used for transportation and manufacturing are imported.

(4) Kenya is able to obtain finance and technology for investment in climate-related projects, such as renewable energy and forestry programmes, through foreign aid and partnerships with the private sector. Overall, these policies will reduce environmental disasters and increase economic growth and jobs in the formal sector.
