Evaluate the case for free trade and the methods and effects of protection on the Australian economy.

What this dot point is asking

This dot point goes deeper than the general case for trade. It asks you to analyse the specific methods governments use to protect industries, work out exactly who gains and who loses, and evaluate the arguments for and against free trade in the Australian context.

Methods of protection

Protection is any government policy that gives domestic producers an advantage over foreign competitors. The main methods are:

• Tariffs: a tax on imports, which raises the price of imported goods so domestic producers can sell more at a higher price.
• Subsidies: payments to domestic producers that lower their costs and let them compete with cheaper imports.
• Import quotas: a legal limit on the quantity of a good that can be imported, which restricts supply and raises the domestic price.
• Local content rules and other non-tariff barriers: regulations, standards and procurement rules that favour local producers.

The effects of a tariff

A tariff is the classic protection diagram. Without trade, the domestic price sits where domestic demand meets domestic supply. With free trade at a lower world price, consumers buy more and imports fill the gap. Imposing a tariff lifts the domestic price toward the world-price-plus-tariff level. The effects ripple through the market:

• Domestic producers gain: they sell more output at a higher price.
• Consumers lose: they pay a higher price and buy less.
• The government gains tariff revenue on the imports that still come in.
• The economy suffers a deadweight loss: resources are drawn into less efficient domestic production and some mutually beneficial trade is lost.

The case for protection

Several arguments are made for protection. The infant industry argument says new industries need temporary shelter until they grow large enough to compete. Protection is also defended to save jobs in import-competing industries, to maintain national security in essential industries, to prevent dumping (foreign goods sold below cost), and to diversify the economy. These arguments have political appeal, especially where job losses are concentrated.

The case for free trade

The economic case for free trade rests on comparative advantage: when countries specialise where their opportunity cost is lowest and trade for the rest, world output rises and consumers enjoy lower prices and wider choice. Free trade also exposes domestic firms to competition, forcing them to lift productivity, and gives them access to larger markets and economies of scale. Against protection, economists point out that it raises prices, props up inefficient firms, invites retaliation that can trigger trade wars, and imposes the deadweight loss shown above.

Australia and trade liberalisation

Since the 1980s Australia has substantially reduced protection, cutting tariffs across manufacturing and dismantling many quotas. This reform exposed industries such as textiles, clothing, footwear and motor vehicles to global competition, contributing to the decline of car manufacturing but also lifting overall efficiency and lowering prices. Australia has pursued the opposite of protection through free trade agreements with partners including China, Japan, Korea and the United States, and through regional agreements, reflecting its position as a relatively open, trade-exposed economy.

A strong answer explains each method of protection, uses the tariff diagram to identify gainers and losers and the deadweight loss, weighs the arguments for protection against the efficiency case for free trade, and applies this to Australia's shift toward liberalisation.
