Case Study: Australia's Comparative Advantage in Iron Ore

The Australian economy is one of the most competitive in the production of iron ore, which is mainly driven by the country's naturally rich resource deposits of high-quality iron ore. In addition, the structure of the labour force is ideal for the production of iron ore. Iron ore is highly capital intensive, which is advantageous on Australia's small but highly skilled labour force. While Australia's mining wages are very high, they are compensated by high levels of capital deepening, increasing labour productivity and driving down unit costs of production.

Australia's low level of protection and formation of trading partners such as those with China, Japan and Korea, make accessing iron ore export markets easier.
