Gains from trade: the simple view
• Clear gains if countries are strong in different areas: absolute advantages
• Less obvious - but undisputed - gains even if one country is “better” in all areas: comparative advantages

Comparative advantages
⓿Trade is profitable as soon as relative prices differ between countries
⓿Why are there differences in relative prices? ⓿Classical and neoclassical theory:
– technology differences (Adam Smith 1776 / David Ricardo 1815)
– differences in factor endowments (Heckscher-Ohlin 1930)

Policy conclusions: neoclassical theory
③Free trade and specialization is optimal ③pattern of comparative advantages is given by
nature
③all industries are equally “desirable”
③International framework should support development of free trade
③unilateral liberalization more difficult because of protectionist interest groups and lack of coordination
Ari Kokko

But why is world trade not free?
• Protectionism leads to higher prices, lower consumption, and lower welfare both at home and abroad...
• …so why is there still a lot of protectionism?
Ari Kokko
Unequal gains from trade at the micro level
• Interest groups matter: trade benefits some groups but hurts others
• trade raises the rewards of a country’s abundant factor of production and reduces the rewards of the scarce factor (Stolper-Samuelson theorem)
• the groups that lose may oppose free trade
• the transition to free trade may have troublesome social consequences
