| Question | Answer |
|---|---|
| Classic Theories of international trade | mercantilism, absolute advantage, comparative advantage |
| mercantilism | the wealth of the world is fixed a nation that exports more than imports and captures a net inflow of wealth and becomes richer |
| According to mercantilism international trade is viewed as a | zero sum game |
| absolute advantage | to be efficient at the production of a good/service than others. A nation benefits by specializing in economic activities in which they possess an absolute advantage |
| comparative advantage | gains from trade arise from differences in factor endowments or technological process |
| An agent has comparative advantage over another in producing something when he/she can | produce a good at a lower relative opportunity cost |
| Modern theories of international trade | product life cycle, strategic trade, and national competitive advantages of industries |
| product life cycle | the 1st dynamic theory to account for changes in the patterns of trade over time |
| strategic trade | strategic intervention by governments in certain industries can enhance their odds for international success |
| new product, maturing product, standardized product | The product life cycle |
| national competitive advantages of industries | represented by the Porter Diamond |
| The Porter Diamond | firm strategy-structure-and rivalry, domestic demand conditions, related and supporting industries, country factor endowments |
| mercantilism main point | governments should protect domestic industries and promote exports |
| mercantilism weakness | inefficient allocation of resources- reduces wealth of nation in the long run |
| absolute advantages main points | by specializing and trading each nation produces more and consumes more. The wealth of all trading nations and the world increases |
| absolute advantages weakness | when one nation is absolutely inferior than another the theory is unable to provide any advice- when there are many nations it may be difficult to find an absolute advantage |
| comparative advantage main points | even if one nation is absolutely inferior then other nations can still gainfully trade - factor endowments underpin com. adva. |
| comparative advantage weakness | realistically static assuming that comparative advantage and factor endowments do not change over time |
| product life cycle main points | production migrates to other advanced nations and then developing nations in different product life cycles |
| product life cycle weakness | the US may not always lead in innovation - many new products are now launched simultaneously around the world |
| strategic trade main points | strategic intervention by governments may help domestic firms reap 1st mover advantages |
| strategic trade weakness | ideological resistance from many 'free trade' scholars and policy makers - invites all kinds of industries to claim they are strategic |
| national comparative advantage main points | comparative advantage of different nations depends on the 4 interacting aspects of a diamond |
| The Porter Diamond 1 | factor endowment |
| The Porter Diamond 2 | domestic demand |
| The Porter Diamond 3 | firm strategy structure and rivalry |
| The Porter Diamond 4 | related and supporting industries |
| national competitive advantage of industries weakness | has not been comprehensively tested, overseas and domestic demand may stimulate the competitiveness of certain industries |
