Diminishing returns in agriculture
Land = fixed factor of production -> decreasing marginal product
MPL
Subsistence wage
Labor

Exports dominated by primary commodities
Export: primary commodities, low value added
Import: manufactured goods
Ratio of export to import prices = barter terms of trade
Terms of trade of primary goods relative to manufactured goods have been falling down
Prices of primary commodities cyclically volatile
Low level of diversification
Primary commodities as a percentage of exports East Asia and Pacific South Asia Latin America and Caribbean Middle East and North Africa Sub-Saharan Africa
