Study Notes
Economic Growth I: Capital Accumulation and Population Growth
- This chapter covers the closed economy Solow model.
- The model demonstrates how a country's standard of living depends on its saving and population growth rates.
- The model examines how to use the "Golden Rule" to find the optimal saving rate and capital stock.
- It explains how output (y) changes over time, and why some countries are rich or poor.
- A country's wealth depends on investment and depreciation, including both its rate of saving and the percentage of capital wearing out in any given period.
- Infant mortality rates are significantly higher in the poorest countries (20%) compared to the richest (0.4%).
- In Pakistan, 85% of the population lives on less than $2/day illustrating high poverty levels.
- Many of the poorest countries have experienced famines over recent decades.
- Poverty is often associated with oppression of women and minorities.
- Economic growth improves living standards and reduces poverty.
- Income per capita and related factors like life expectancy, infant mortality, malaria deaths, adult literacy, and cell phone users are correlated, indicating that economic growth is associated with a better quality of life.
- Small changes in long-term economic growth rates have enormous impacts on living standards over the long term.
- A one-tenth of one percent increase in the annual growth rate of U.S. real GDP per capita from 2000 to 2010 would have resulted in $2,782 more income per person in that decade.
- The Solow model, developed by Robert Solow, provides a framework for analyzing economic growth.
- It's a major paradigm in policy making, acting as a benchmark for evaluating the performance of economic growth theories.
- The Solow model analyses the driving factors for economic growth and long-term standard of living.
- The Solow model differs from previous models by considering investment and depreciation affecting capital stock, as well as population growth affecting the labor force.
- The simple consumption function becomes simpler.
- The model uses the production function Y = F(K, L) to analyze the relationship between output, capital (K), and labor (L) in an economy.
- This model simplifies the analysis by using the per-worker production function y = f(k) where y = Y/L and k = K/L.
- The production function exhibits diminishing MPK (marginal product of capital).
- The national income identity Y = C + I is introduced.
- Saving rates (s) are an important exogenous factor.
- Consumption function is c = (1-s)y.
- Saving = y - c = sy, where y is output per worker and c is consumption per worker.
- Investment is equal to saving for model simplification.
- The relationship between s, f(k), and k is used to calculate the rate of change of k over time (Δk).
- If investment is sufficient to cover depreciation, the change in capital per worker will remain constant(Ak = 0).
- Determining the steady state value of k is done by analyzing investment and depreciation rates in relation to k and its point of equilibrium.
- Population growth impacts investment rates, reducing income per capita in the long run.
- Break-even investment is the total amount of investment required to keep capital per worker relatively constant during a period.
- The Solow model equation, with population growth, is Δk = s f(k) – (δ + n) k.
- The 'Golden Rule' capital stock(k gold) finds the maximum sustained level of consumption per person, which occurs at the point where MPK (Marginal Product of Capital) = δ + n (the depreciation rate plus the population growth rate).
- Transition to Golden Rule steady state is often not easy, as adjustments in saving rates in relation to capital, population growth, and other factors can result in a period of declining consumption until higher rates are achieved.
- Capital accumulation is affected by investment rates and depreciation rates.
- Population growth leads to a lower steady state capital stock and income overall.
- Alternative views such as the Malthusian model predict population growth exceeding resource production, leading to societal impoverishment.
- Kremer's model, in contrast, argues that population increase positively influences economic growth via increases in technological advancement.
