International trade and the global economy Revision Notes

Defining Exchange Rates

An exchange rate is the price of one country's currency in terms of another country's currency. For example, if £1 buys €1.15, then the exchange rate for the British Pound against the Euro is 1.15. These rates are dynamic and constantly change based on economic factors. Understanding the concept of appreciation (strengthening) and depreciation (weakening) is fundamental. Appreciation means a currency can buy more of a foreign currency, while depreciation means it can buy less.

Factors Influencing Exchange Rates

Several key factors drive exchange rate movements. Demand for a currency rises when foreign consumers want to buy a country's exports, or when foreign investors want to invest in its businesses or financial assets (e.g., bonds). Supply of a currency rises when domestic consumers buy imports or domestic investors invest abroad. Other factors include interest rates (higher rates can attract foreign investment, increasing demand for the domestic currency), inflation rates (higher domestic inflation can reduce demand for exports and increase demand for imports, weakening the currency), and speculative activity in the foreign exchange market where traders buy or sell currencies based on anticipated future movements.

Impacts of Exchange Rate Changes

A stronger currency (appreciation) makes imports cheaper and exports more expensive. This can reduce import-led inflation, but might harm export industries and worsen a country's balance of trade. A weaker currency (depreciation) makes imports more expensive and exports cheaper. This can lead to imported inflation but can boost exports, potentially improving the balance of trade and creating jobs in export sectors. Businesses involved in international trade must consider exchange rate fluctuations in their planning, as they affect profitability and competitiveness. Consumers also feel the impact through the prices of imported goods and services, and the cost of foreign travel.

Components of the Balance of Payments

The Balance of Payments (BoP) is a record of all transactions between a country and the rest of the world, typically over a year. It's split into two main sections: the Current Account and the Capital and Financial Account. The Current Account tracks trade in goods (visible trade), trade in services (invisible trade), primary income (like wages, interest, and dividends received from abroad or paid abroad), and secondary income (such as international aid or workers' remittances). A surplus means more money is flowing into the country for these items, while a deficit means more is flowing out. The Capital and Financial Account records purchases and sales of assets, such as foreign direct investment (FDI), portfolio investment (stocks and bonds), and changes in official reserves. These accounts must, in theory, balance each other out over time, though statistical discrepancies usually occur.

Understanding Current Account Surpluses and Deficits

A current account surplus implies that a country is earning more from its exports of goods, services, and income flows than it is spending on imports and income payments to other countries. This often means the country is a net lender to the rest of the world, accumulating foreign assets or reducing foreign liabilities. Conversely, a current account deficit means a country is spending more internationally than it earns. To finance this deficit, the country must borrow from abroad or sell off its assets to foreigners, which is recorded in the capital and financial account. Persistent deficits can indicate a lack of international competitiveness, over-reliance on imports, or an economy that is living beyond its means. Surpluses can be a sign of strong export performance and national saving.

Capital and Financial Account explained

The Capital Account is relatively small and primarily records transfers of non-produced, non-financial assets (e.g., patents, copyrights) and capital transfers (like debt forgiveness). The Financial Account is much larger and records transactions involving financial assets and liabilities. This includes Foreign Direct Investment (FDI), where investors gain lasting interest in an enterprise in another country (e.g., building a factory). It also covers Portfolio Investment, which involves buying shares or bonds purely for financial return without significant control. Other investments include loans and foreign currency deposits. Changes in a country's official reserves (foreign currencies, gold held by the central bank) also form part of the financial account. A financial account surplus typically finances a current account deficit, and vice-versa.

Benefits for Consumers

International trade offers consumers a wider selection of goods and services than could be produced domestically. This increased choice caters to diverse preferences and often leads to lower prices due to greater competition among producers globally. Access to innovative products and high-quality items from around the world can significantly improve consumer welfare and living standards. For example, a country might import tropical fruits that cannot be grown locally, or specialised electronics that are only manufactured efficiently in certain regions, thereby enriching consumer options.

Benefits for Businesses and Economic Growth

Businesses engaged in international trade can benefit from larger markets beyond their domestic borders, allowing them to achieve economies of scale. Producing for a larger global customer base can reduce average production costs, leading to increased competitiveness. Access to foreign markets can also mean higher profits and opportunities for growth and expansion. Furthermore, countries can import essential raw materials, components, or advanced machinery that are not available or are too costly to produce domestically, which is crucial for modern industrial production and technological advancement, thereby fostering overall economic growth.

Specialisation and Efficiency

A core principle of international trade is specialisation. Countries tend to produce goods and services where they have a comparative advantage, meaning they can produce them at a lower opportunity cost than other countries. This specialisation leads to a more efficient allocation of global resources, as each country focuses on what it does best. The result is increased overall output in the global economy, benefiting all participating countries through trade. This efficiency gain contributes to lower global prices and a greater quantity and quality of goods available worldwide.

Potential Drawbacks and Challenges

Despite its many benefits, international trade can also pose certain challenges. Domestic industries that face stiff competition from cheaper or higher-quality imports may struggle, potentially leading to job losses and economic restructuring within those sectors. There can also be an over-reliance on foreign suppliers for critical goods, which could create vulnerability during times of geopolitical tension or supply chain disruptions. Furthermore, countries might face challenges related to trade imbalances, intellectual property theft, or exploitation of labour in less developed economies, requiring careful consideration and regulation.

What is Globalisation?

Globalisation is the process of increasing interconnectedness and integration between countries. This involves the free movement of goods, services, capital, technology, and labour across national borders. It's a complex phenomenon that affects economic, social, cultural, and political aspects of life. Key indicators include growing international trade, foreign direct investment, and the spread of multinational corporations.

Factors Causing Globalisation

Several factors drive globalisation. Technological advancements, especially in communication (e.g., internet, mobile phones) and transportation (e.g., containerisation, air travel), have drastically reduced the cost and time of moving goods, services, and information globally. Reduced trade barriers, such as lower tariffs and quotas implemented through international agreements like those under the World Trade Organization (WTO), also encourage international trade. The growth of multinational corporations (MNCs) seeking new markets, lower production costs, and raw materials further fuels this trend by establishing operations in various countries.

Impacts of Globalisation: Benefits

Globalisation offers several potential benefits. It can lead to increased economic growth as countries specialise in producing goods and services where they have a comparative advantage, leading to greater efficiency and output. Consumers often benefit from lower prices due to increased competition and a wider variety of goods and services. It can also promote innovation and the transfer of technology and knowledge between countries, fostering development. Developing countries may attract foreign direct investment, creating jobs and improving infrastructure.

Impacts of Globalisation: Drawbacks

Despite the benefits, globalisation also has significant drawbacks. Developed countries can experience job losses as companies move production to countries with lower labour costs, leading to structural unemployment. There are concerns about environmental degradation due to increased industrial activity and international transport. Globalisation can exacerbate income inequality, both within countries (e.g., between skilled and unskilled workers) and between developed and developing nations, if the benefits are not shared equitably. Furthermore, it can lead to a loss of cultural distinctiveness in some regions.
