Literature on economic development is Literature on economic development is dominated by the following four strands of dominated by the following four strands of thought: thought: Linear-stages-of-growth model: 1950s and Linear-stages-of-growth model: 1950s and

The Harrod-Domar Growth The Harrod-Domar Growth Model Model

The principal strategy for development is The principal strategy for development is mobilization of saving and generation of mobilization of saving and generation of investment to accelerate economic growthinvestment to accelerate economic growth

Investment comes from savings Investment comes from savings Rate of economic growth (GNP growth Rate of economic growth (GNP growth

Obstacles and Constraints Obstacles and Constraints

Problem with the argument that GDP growth Problem with the argument that GDP growth is proportional to the share of investment is proportional to the share of investment expenditure in GDPexpenditure in GDP

Low rate of savings in developing countries Low rate of savings in developing countries gives rise to savings gap and capital gives rise to savings gap and capital constraint constraint

Savings and investment is a necessary Savings and investment is a necessary condition for accelerated economic growth condition for accelerated economic growth but not a sufficient conditionbut not a sufficient condition

Structural-Change Models Structural-Change Models

Structural-change theory focuses on the Structural-change theory focuses on the mechanism by which underdeveloped mechanism by which underdeveloped economies transform their domestic economies transform their domestic economic structures from traditional to a economic structures from traditional to a developed urbanized industrial economydeveloped urbanized industrial economy

The speed of expansion in the modern sector The speed of expansion in the modern sector is determined by the industrial investment is determined by the industrial investment which is possible by the excess profit over which is possible by the excess profit over wages in the modern sector so industrialist re-wages in the modern sector so industrialist re-invest it. invest it.

The process of self-sustaining growth and The process of self-sustaining growth and employment expansion continues in the employment expansion continues in the modern sector until all of the surplus labor is modern sector until all of the surplus labor is absorbedabsorbed

Application: Do Economies Application: Do Economies Converge? Converge?

Unconditional convergenceUnconditional convergence occurs occurs when poor countries will eventually when poor countries will eventually catch up with the rich countries (LR) catch up with the rich countries (LR) resulting in similar living standardsresulting in similar living standards

Conditional convergenceConditional convergence occurs when occurs when countries with similar characteristics will countries with similar characteristics will converge (savings rate, investment rate, converge (savings rate, investment rate, population growth)population growth)

No convergenceNo convergence occurs when poor occurs when poor countries do not catch up over time and countries do not catch up over time and living standards may divergeliving standards may diverge
