Study Notes

Inflation & Deflation

GDP Deflator is a measure of the price level calculated as the ratio of nominal GDP to real GDP, multiplied by 100.
Consumer Price Index (CPI) tracks changes in the cost of a basket of goods and services purchased by a typical household.
Inflation is the percentage change in the price level as measured by the GDP deflator or CPI.
Disinflation is a period of slowing inflation.
Deflation is a period of falling prices.

Interest Rates & Inflation

Nominal interest rate (i) is the interest rate before taking inflation into account
Real interest rate (r) is the interest rate adjusted for inflation.
The relationship between the nominal interest rate (i), the real interest rate (r), and the inflation rate (π) is represented by the Fisher equation:
- i = r + π or r = i - π

Economic Growth

Economic Growth is the change in real GDP over time.
Growth Rate is the annual percentage change in real GDP.
Rule of 70 is a shortcut to estimate the time it takes for a variable to double.
Years to Double = 70 / Growth Rate
Per Capita GDP Growth Rate is the growth rate of real per capita GDP, a key indicator of changes in living standards.
%Δ Real Per Capita GDP = %ΔY - %Δpop, where %ΔY is the growth rate of real GDP, and %Δpop is the growth rate of the population.

Productivity

Productivity is the average quantity of goods and services produced per hour of labor input.
Productivity = Y/L (output per labor hour), where Y represents real GDP and L represents the number of labor hours.

Convergence

Convergence is the idea that poorer countries will grow faster than richer countries, eventually leading to a convergence in GDP per capita over time.
Absolute Convergence asserts that convergence is inevitable due to strong economic forces.
Contingent Convergence suggests convergence is possible but not guaranteed, depending on factors such as government policies, institutional quality, and access to technology.

### Approaches to Development

Environmental Approach states that geographical factors such as climate, endemic diseases, landlockedness, and natural resource availability significantly influence a country's economic development.
International Trade Approach emphasizes the benefits of integrating into the global economy through trade in goods and services and capital flows.
Institutional Approach highlights the importance of strong and effective institutions for economic development, including a reliable legal system, political stability, and control of corruption.

Gross Domestic Product (GDP)

GDP is the market value of all final goods and services produced within a country in a year.
Components of GDP (Expenditure Approach):
- Personal Consumption Expenditures (C): Household spending on goods and services.
- Gross Private Domestic Investment (I): Business spending on capital goods, residential investment and changes in inventories.
- Government Purchases (G): Spending by all levels of government on goods and services.
- Net Exports (NX): Exports minus imports.

### Nominal vs. Real GDP

Nominal GDP values output using current prices.
Real GDP values output using a constant set of prices from a base year.

Types of Unemployment

Frictional Unemployment arises from the time it takes for workers to search for and find new jobs.
Structural Unemployment happens when there is a mismatch between the skills workers possess and the skills demanded by employers.
Cyclical Unemployment is related to fluctuations in the business cycle and rises during economic downturns.

Factors Influencing the Natural Rate of Unemployment

Government Policies (training programs, unemployment compensation, minimum wage laws).
Labor Unions.
Efficiency Wages.
