Study Notes

Classical Growth Theory

Key classical economists include Adam Smith, David Ricardo, Thomas Malthus, John Stuart Mill, and Karl Marx.
Adam Smith highlighted growth potential through the division of labor and specialization, constrained by market size.
Ricardo, Malthus, and Mill expressed concerns about diminishing agricultural returns leading to famine and declining profits.
Marx theorized capitalism's collapse due to falling profit rates, worker immiseration, and realization crises.

Harrod-Domar Growth Model

Developed by Roy Harrod (1939) and independently by Domar (1946).
Introduces three growth rates: actual (g), warranted equilibrium (gw), and natural (gn).
Equilibrium occurs when g equals gw, which is rare.
If gw is greater than gn, secular stagnation results; if gn exceeds gw, structural unemployment and inflation emerge.
Many developing countries experience faster growth in labor and technology than in capital, leading to structural unemployment.

Neoclassical Growth Model

Proposed by Solow (1956) and Swan (1956) as a counter to Harrod's pessimism.
Suggests economies converge to a natural growth rate via capital-labor substitution.
If capital grows faster (gw > gn), it uses more capital-intensive techniques, reducing gw.
If labor grows faster (gn > gw), it drives more labor-intensive techniques, increasing gw.
Claims poorer nations grow faster due to higher marginal returns on capital, promoting convergence in per capita incomes.

Production Function Approach to Analysis of Growth

Uses a neoclassical production function to link aggregate output to labor, capital, and technical progress.
Elasticities of output concerning labor and capital enable estimation of their contributions to growth.
Developed countries show technical progress as key to growth; in contrast, developing nations show capital input as crucial.
The production function approach is flexible, allowing the inclusion of various growth-inducing variables, e.g., education and R+D.

New (Endogenous) Growth Theory

Emerged in the 1980s, challenging diminishing returns assumptions in neoclassical theory.
Empirical evidence indicates no convergence in global economies due to sustained high marginal products of capital in rich countries.
Human capital (education) and R+D are identified as vital growth factors.
Conditional convergence may occur if education levels across nations were equal, leading to 'catch up' by poorer countries.

Growth Diagnostics and Binding Constraints on Growth

Examines unique growth experiences across countries and identifies binding constraints affecting growth rates.
Variability in country growth patterns highlights the need for tailored growth diagnostics.
Identifies potential causes for low investment: finance availability, cost of finance, low investment returns, etc.
World Bank Commission emphasizes successful countries have high savings and investment, fast export growth, macroeconomic stability, technological advancements, and market-friendly policies.

Learning Objectives

Understand classical economists' views on economic growth.
Familiarity with Harrod-Domar and Solow neoclassical growth models.
Grasp the production function's role in understanding growth sources.
Recognize key arguments from endogenous growth theory.
Comprehend the significance of growth diagnostics in identifying growth constraints.

Summary

Early economists had differing views on growth, with Smith optimistic and others more pessimistic.
Harrod's model re-energized growth theories in 1939.
Solow's model suggests long-term equilibrium growth may be achievable.
Production function studies differentiate the importance of technical progress in developed countries versus capital input in developing countries.
Endogenous growth theory explains persistent disparities in living standards through non-diminishing returns and human capital.
Growth diagnostics are necessary to understand individual country experiences and obstacles to growth.
