What are the assumptions that we make when we discuss a simple Ricardian model to
support free trade?
1. We have assumed a simple world in which there are only two countries and two goods.
2. We have assumed away transportation costs between countries.
3. We have assumed away differences in the prices of resources in different countries.
4. We have assumed that resources can move freely from the production of one good to
another within a country.
5. We have assumed constant returns to scale.
6. We have assumed that each country has a fixed stock of resources and that free trade
does not change the efficiency with which a country uses its resources.
7. We have assumed away the effects of trade on income distribution within a country.
