Study Notes

Introduction to economics

Economics studies how individuals and society manage scarce resources.
Scarcity in economics means that people's wants are unlimited, but the resources to satisfy them are limited.
Microeconomics focuses on individual behavior and firms in the economy.
Macroeconomics studies the economy as a whole, analyzing determinants like total output, inflation, unemployment, national income, and economic growth.
A mixed economic system combines government intervention with private enterprise.
A command economy is where the government makes most economic decisions.
Government macroeconomic objectives include economic growth (4%), low unemployment (4%), low inflation (2%), and long-term balance of public finances.
Classical economists advocate for a laissez-faire economy emphasizing minimal government intervention.
Keynesian economics promotes government intervention to stabilize the economy and minimize boom/bust cycles.
The four factors of production are land, labor, capital, and enterprise.
Corresponding payments for these factors are rent, wages, interest, and profit.

National Income

Gross Domestic Product (GDP) measures the total value of goods and services produced within a country in a year, regardless of who produces them.
GDP = Consumption (C) + Investment (I) + Government expenditure (G) + Exports (X) - Imports (M).
Gross National Product (GNP) measures the total value of goods and services produced by a country's residents in a year, regardless of their location.
GNP = GDP + Net Factor Income (F).
Net Factor Income (F) includes payments from the rest of the world, like profit repatriation by foreign-owned companies.
GDP per capita is calculated by dividing GDP by the population and is useful for international wealth comparisons.
GDP deflator/inflator measures the inflation rate.
Real GDP is calculated by dividing the nominal GDP by the GDP deflator.
Net National Product (NNP) is GNP minus depreciation.
Real GDP growth measures the percentage change in real GDP between periods.
A recession is characterized by a decline in real GDP (negative growth).
