Summary of International Trade Teory

What it is? Is exchange of capital, goods, and services across international borders or territories. In most countries, it represents a significant share of gross domestic product (GDP). While international trade has been present throughout much of history (see Silk Road, Amber Road), its economic, social, and political importance has been on the rise in recent centuries.

The senior trade commissioners working in the Canadian embassies and consulates are very helpful because the Canadian exporters but when you ask them for advice importing from another country there is not the same level of assistance.

Adam Smith said about the each nation should specialize in producing things it has an "absolute advantage" what refers to the ability of a party (an individual, or firm, or country) to produce more of a good or service than competitors, using the same amount of resources. Adam Smith first described the principle of absolute advantage in the context of international trade, using labor as the only input.

In my opinion the New Trade Theory tries to explain empirical elements of trade that comparative advantage-based models above have difficulty with. These include the fact that most trade is between countries with similar factor endowment and productivity levels, and the large amount of multinational production (i.e. foreign direct investment) which exists. New Trade theories are often based on assumptions like monopolistic competition and increasing returns to scale. One result of these theories is the home-market effect, which asserts that, if an industry tends to cluster in one location because of returns to scale and if that industry has high transportation costs, the industry will be located in the country with most of its demand to minimize.
