Lecture 2 - Pre-modern Economy Flashcards
MALTHUSIAN MODEL
Birth rates increasing in p.c. incomes
Death rates decreasing in p.c. incomes
Malthusian Model (Graphically)
See Notes
Pre-modern production function
y = AL^(-a)
=> Population rise leads to a per capital income fall
Malthusian trap
Population growth pushes p.c. income to subsistence levels
=> Simple account of how pre-industrial economies operated
Mechanism of Malthusian Trap
1) Positive checks - increase in death rate
2) Preventive checks - decrease in birth rate
Malthusian Trap (Graphically)
See Notes
PRE-MODERN EFFLORESCENCES
P.c. income levels rose above subsistence levels for prolonged periods of time
Economic Growth in Pre-Modern Economies
1) Adam Smith
- Larger population = more specialisation
- Specialisation = technological progress (learning by doing)
2) David Ricardo
- Production of goods with comparative advantage
- International trade = international division of labour
Smithian growth
Specialisation and trade
=> Divison of labour allows for output growth absent of technological progress
Smithian growth (Steps)
See Notes
Why did Smithian Growth not stay?
p.c. income gains disappear due to:
=> Pressures of disrupting events
=> Climate change, epidemic, conquest
=> Malthusian forces
Smithian Growth (Graphical)
See Notes
Imperialism
Conquests raise p.c. income
More land & conflict deaths => Malthusian growth
Low transaction costs => Smithian (secure transport, common currency, etc.)
LITTLE DIVERGENCE
Incomes diverges in Malthusian world
Three Horsemen of Riches
1) Plague
2) Urbanization
3) War
