Episode notes
Comparative Advantage Drives Mutual Gains
- Comparative advantage explains mutual gains from trade based on opportunity cost, not absolute productivity.
- Charles N. Steele uses Ricardo's example of Portugal specializing in wine and trading for English cloth to show overall value increases.
Freer Trade Raises Growth Through Better Capital Allocation
- Countries moving to freer trade tend to grow faster and enjoy higher incomes, especially via capital goods investment.
- Steele cites Douglas Irwin's documentation connecting freer trade with better allocation of capital and higher productivity.
Wages Follow Productivity Not Just Low Labor Cost
- Low foreign wages do not automatically undercut developed-country wages because wages reflect productivity.
- Steele contrasts US and China early-2000s wages, noting Chinese productivity was roughly one-tenth of US productivity, matching wage differences.
