For each of the following, explain how it can be a source of comparative advantage and provide an example. a. Abundant inputsb. Specialised skillsc. Mass production

a. Abundant Inputs: A country can have a comparative advantage if it has an abundance of certain resources or inputs that are not readily available in other countries. This abundance can lower the cost of production, making it cheaper to produce certain goods or services compared to other countries. For example, Saudi Arabia has an abundant supply of oil, which gives it a comparative advantage in oil production.

b. Specialised Skills: A country can also have a comparative advantage if it has a workforce with specialised skills. These skills can increase the efficiency and quality of production, making it more cost-effective compared to other countries. For example, Switzerland has a long history of watchmaking and has developed specialised skills in this area, giving it a comparative advantage in the production of high-quality watches.

c. Mass Production: A country can gain a comparative advantage through mass production. By producing goods on a large scale, a country can lower the cost per unit, making it cheaper to produce compared to other countries. For example, China has a comparative advantage in the production of many consumer goods due to its ability to mass-produce items at a lower cost.
