Study Notes
Macroeconomics
- Countries are experiencing increased material wealth, but also a decrease in the amount of work needed.
- Even poor countries are seeing significant increases in living standards.
- Rich countries will eventually have to reduce consumption due to decreasing natural resources.
Gross Domestic Product (GDP)
- GDP is the value of all goods and services produced by a country in a year.
- It can be calculated as the total output or the total income.
- GDP is equivalent to national income.
Purchasing Power Parity (PPP)
- PPP is a set of artificially constructed exchange rates.
- It converts amounts from different years and countries.
- The difference in income across countries is significant and can be difficult to comprehend.
High GDP
- A high GDP can be caused by a large population rather than the wealth of the citizens.
- A low population can lead to a high GDP per capita, but a low total GDP.
Growth Rates of Income
- Growth rates of income show how quickly income per capita is increasing.
- Rapid growth leads to a higher income level over time.
Calculating Growth Rate
- To calculate the growth rate, divide the change in X from one year to the next by the value of X in the first year.
- Formula: g = (Xt+1 - Xt) / Xt
Growth during Recent Decades
- Growth is a long-run phenomenon.
- Separating long-run trends (trend growth) from short-term fluctuations (business cycles) is important.
- Long-run movements are harder to identify than short-term fluctuations
Income Inequality
- Income inequality can be within a country (income inequality among the population), or between countries.
- People are more concerned with income inequality within a particular country compared to income inequality between countries
Common Errors with GDP
- Some economic activity goes unrecorded or is hidden.
- Small sample sizes can inaccurately reflect the entire population's output.
- Deliberate falsification of data by governments can occur.
- Errors can arise from the PPP adjustment.
Capital
- Capital includes machines, vehicles, buildings, and equipment.
- More capital per worker leads to greater output.
Investment
- Investment refers to goods and services used to create new capital. This is different from consumption.
- Differences in capital investment can explain income differences between countries.
Investment Rate
- The investment rate is the fraction of a country's income devoted to investment.
Productivity
- Productivity measures the output per unit of capital.
Technology
- Technology refers to available knowledge for combining inputs to produce output.
- Efficiency refers to how effectively inputs are used given available technology.
- Productivity is the product of technology and efficiency.
Fundamentals (Underlying Factors)
- Cultural differences between countries are noted.
- Economic policies (e.g., taxes, tariffs, regulations) differ.
- Geographic factors such as natural resources, climate, and market proximity affect countries' economies.
Factors of Production
- Factors of production are the inputs (factors) that contribute to output.
Production Function
- A production function is a mathematical model describing how inputs are combined to produce outputs.
Panel 1 & 2
- Panel 1 shows that 2 countries might have the same production function but one has more factors of production (C1) than the other (C2).
- Panel 2 shows 2 countries having the same amount of factors, but differing in productivity.
Economic Models
- Economic models are simplified representations of reality.
Quantitative Analysis
- Quantitative analysis involves using data to determine economic magnitudes.
Investment
- Investment in the process and cost of creating capital.
Key Characteristics of Capital
- Capital generated by human exertion, as opposed to natural resources.
- Capital requires sacrifice of consumption from the producing country.
- Capital is usable by only a limited number of users.
- Capital makes returns, but also depreciates.
Capital's Role in Production
- Production functions describe the relationship between output, labor, and factors.
Solow Model
- The Solow model assumes constant inputs and no improvements in productivity.
- Model assumes capital accumulation is the only determining factor in explaining income.
Steady State
- A steady state is reached when an increase in capital input is matched by a corresponding increase in depreciation.
Between 2 Countries
- Determine the ratio by dividing the smaller output by the larger output.
- Higher ratio indicates a greater investment level.
Population
- Population growth influences a country's consumption and productive capacity.
- Rapid growth can lead to poverty.
- Population growth and income per capita may be indirectly related.
- Population growth, mortality rates, and fertility rates affect a country.
Malthusian Model
- The Malthusian model highlights the importance of food supply in determining living standards, emphasizing population growth limits.
- The model shows that higher productivity doesn't automatically lead to higher living standards but rather may lead to a rapidly growing population.
Demographic Transition
- The transition refers to a country's changing demographic characteristics related to development.
- Wealthy countries have mostly completed this demographic transition.
- Developing countries are still in different stages of the demographic transition.
Total Fertility Rate (TFR)
- TFR measures the average number of children a woman is expected to have in her lifetime.
Human Capital
- Human capital represents the skills, knowledge, and abilities of people.
Productivity (Countries)
- Productivity measures the efficiency of transforming factors of production into outputs.
- Differences in productivity lead to differences in outputs among countries.
Growth Accounting
- Growth accounting compares productivity growth rates among countries.
- It involves measuring growth rates of productivity and factors of production.
Inefficiency Types
- Unproductive activities,
- Idle resources,
- Misallocation of factors among sectors, or firms,
- and technology blockage lead to inefficiency.
R&D
- Firms undertake research and development spending for anticipated profit from new products or methods.
Patent
- Patents legally protect an inventor's rights.
One-Country Model
- Ignore the role of capital to focus on labor as the only input, to simplify the analysis.
Two-Country Model
- The transfer of technologies between countries is an important consideration.
- Innovation (creating new technology) and imitation (copying technology) are two ways of acquiring new technology.
Non-renewable Resources
- Non-renewable resources are finite and consumption depletes them permanently.
Renewable Resources
- Renewable resources are replenished naturally and can be used repeatedly.
Property Rights over Resources
- Property rights to resources can solve the "tragedy of the commons," where overconsumption depletes resources, while overuse harms the entire population.
- Resource scarcity is addressed by limiting resource use through regulated resource consumption.
