  1. Vicious and Virtuous Circles Vicious circle of debt Debt  Child Labor  Low Education  Poverty Virtuous circle of development Per capita real GDP  Health  Productivity

  2. W.W. Rostow: Best & the Brightest?Stages of Economic Growth Traditional Society Transition: Preconditions to Take Off Emergence of Capitalist/Commercial Sector Finance/Transport Infrastructure Take Off Political change  Protection of private property Accumulation  Compound Growth Maturity Diversification / Import Substitution Mass Consumption Society / Welfare State

  3. Penn World Table: Heston, Summers, Aten Want Real GDP in comparable units ($2000) • Define global output basket • Price the basket in each country • Basket costs …………….. ZL 220 in Poland • Basket costs ………………$ 100 in U.S. • PPP Exchange Rate …….. ZL 2.2/$1 (as opposed to market exchange rate of ~ ZL 4/ $1

  4. Penn World Table:Heston, Summers, Aten • Polish 2004 gdp per capita ………. ZL 22,560 • Translated to $s @ ZL 2.19/$ ………$ 10,484 • This was Polish PPP per capita gdp in 2004 $s • It was 26.5% as great as US gdp per capita in 2004 • If Polish gdp had been translated into dollars at the 2004 market exchange rate of ZL 3.66/$, Polish gdp would have measured only $6,273 per capita • only 15.9% of US per capita gdp of $39,535 • 2004 dollars don’t go as far as 2000 dollars • Adjusting for dollar inflation, 2004 Polish Real GDP Per Capita in 2000 dollars is $9,705 in PPP dollars • This compares with 2003 real gdp per capita of $9,216 • Poles enjoyed a 5.3% growth in real per capita gdp

  7. Adam Smith’s Glorious Vision Accumulation + Division of Labor = Cumulative Progress

  8. Adam Smith • Accumulation: • “capitals are increased by parsimony and diminished by prodigality and misconduct.” • Division of labor: • “… natural propensity among men to truck, barter, and exchange one thing for another.”

  9. Adam Smith: • The division of labor is limited by the extent of the market. • Free Trade  Extended Market

  10. Adam Smith:Virtuous Circle of Growth • Accumulation • | • Division of Labor • | • Productivity • | • Reduced Cost • | • Extended Market • | • Profit

  11. Adam Smith:Limit to Growth • Accumulation | • Competition Up | • Profit Down • Steady State: “that full complement of riches which the nature of [a nation’s] soil and climate, and its situation with respect to other countries, allow it to acquire.”

  12. Getting to Take-Off: Foreign Aid? Harrod – Domar Model  Financing Gap Y = k K • Labor doesn’t matter  there’s surplus labor Sir W. Arthur Lewis • Constant marginal productivity of capital ΔY = kΔ K = k I g = ΔY/Y = k (I/Y) • Investment share of gdp limited to national saving … unless you get injections from abroad • With k = output:capital ratio ≈.25, need saving rate of 20% to achieve growth of 5%  Poor country needs grants and loans … foreign aid Rostow: Once growth takes off, national saving up Easterly: But it doesn’t – incentive is to consume
