2 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE WHAT IS SPECIALISATION AT A MACRO LEVEL? International specialisation in economics refers to where countries or regions focus on producing and exporting specific goods or services in which they have a comparative advantage, while importing other goods or services that they can acquire more efficiently from trading partners. This specialisation allows countries to allocate their scarce factor resources more efficiently, improve overall productivity, and hopefully benefit from the gains of trade across borders.

3 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE EXAMPLES OF TRADE SPECIALISATION Oil Exporting Countries: Countries like Saudi Arabia and Venezuela specialize in the production and export of oil due to their abundant natural resources Agricultural Specialisation: Ethiopia is a major exporter of coffee due to its favorable climate for coffee cultivation. Textile and Apparel Industry: Countries like Bangladesh and Vietnam have specialized in textile and apparel manufacturing due to their relatively low labour costs and skilled workforce Medical Tourism: Countries like Thailand and India have specialised in medical tourism, offering high-quality medical procedures and treatments at lower costs compared to some Western countries.

8 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE WHAT IS COMPARATIVE ADVANTAGE? Comparative advantage helps explain the benefits of specialisation and trade between individuals, firms, or countries. It arises when one party can produce a good or service at a relatively lower opportunity cost than another party. In simpler terms, it's about assessing which activity a party is relatively more efficient at producing compared to other activities. The concept was introduced by British economist David Ricardo in the early 19th century as part of his theory of international trade.

9 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE DAVID RICARDO AND COMPARATIVE ADVANTAGE David Ricardo was one of the founding fathers of classical economics. He developed the idea of comparative advantage Comparative advantage exists when: 1.The relative opportunity cost of production for a good or service is lower in one nation than in another country. 2.A country is relatively more productively efficient than another. Basic rule: Specialise a country’s scarce factor resources in goods and services that they are relatively best at. This opens potential gains from specialisation and trade which leads to improved economic welfare. David Ricardo (1772-1823)

The labour input and other inputs are initially divided equally between the two countries. The table shows the resulting weekly output of LCD screens and e-vehicle chargers

This is because the opportunity cost of an extra unit of beef is 4/5 th unit of tobacco, whereas for Malawi, the opportunity cost is 1.5 units of tobacco. Malawi has a comparative advantage in producing tobacco – the opportunity cost of an extra unit of tobacco is 2/3rd of beef, whereas for Australia it is 5/4.

28 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE FACTORS AFFECTING COMPARATIVE ADVANTAGE

29 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE ASSUMPTIONS OF COMPARATIVE ADVANTAGE MODEL Key assumptions behind trade theory are as follows: 1.Constant returns to scale – no economies of scale. 2.Factor mobility between industries (geographical + occupational mobility), workers are assumed to be equally productive in whatever job they do 3.No trade barriers such as import tariffs and quotas 4.Low transportation costs to get products to market 5.No externalities from production and/or consumption Mutually beneficial terms of trade is not necessarily one that benefits both countries equally – the benefits may be unbalanced Key assumptions behind trade theory are as follows: 1.Constant returns to scale – no economies of scale. 2.Factor mobility between industries (geographical + occupational mobility), workers are assumed to be equally productive in whatever job they do 3.No trade barriers such as import tariffs and quotas 4.Low transportation costs to get products to market 5.No externalities from production and/or consumption Mutually beneficial terms of trade is not necessarily one that benefits both countries equally – the benefits may be unbalanced

30 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE FACTORS AFFECTING COMPARATIVE ADVANTAGE Comparative advantage is a dynamic concept - it changes over time 1.Quantity and quality of natural resources available 2.Demographics – factors such as an ageing population, net migration, levels of women’s participation in the labour force 3.Rates of capital investment including infrastructure spending 4.Investment in research which can drive business innovation 5.Fluctuations in the exchange rate which then affect prices of both exports and imports 6.Import controls such as import tariffs, export subsidies and quotas used to create an artificial comparative advantage 7.Non-price competitiveness of producers – such as product design, innovation, reliability, branding & technical standards.

31 TUTOR2U.NET/ECONOMICS SPECIALISATION AND TRADE GAINS FROM TRADE – ECONOMIC EFFICIENCY Economic efficiencyPossible impact of trade on economic efficiency Allocative efficiency Competition from lower-cost import sources drives market prices down closer to marginal cost. Lower prices reduces the level of monopoly profits and increases real incomes. Productive efficiency Specializing and selling in larger markets encourages increasing returns to scale (internal economies of scale) leading to a lower long run average cost of production. Dynamic efficiency Economies that are open to trade may see growing numbers of innovative businesses who invest more in research and development and in the human capital of their workforce which can help raise labour productivity. X-inefficiency Intense competition in markets provides a discipline on businesses to keep their operating costs under control and reduce waste to remain price competitive and profitable.

46 In 1817, David Ricardo developed the classical theory of comparative advantage. The theory of comparative advantage suggests that countries should A Seek to become self-sufficient B Only trade if each country has an absolute advantage in at least one product C Diversify as much as possible D Only trade if the opportunity costs of production differ between countries In 1817, David Ricardo developed the classical theory of comparative advantage.
