Study Notes

Microeconomics

Microeconomics studies the behavior of individual economic agents, such as households and firms, and the interactions among them in specific markets.
It focuses on how these agents make decisions regarding the allocation of scarce resources.
Key concepts include supply and demand, elasticity, market structures (perfect competition, monopoly, oligopoly), production, cost, and pricing.
Microeconomics helps explain how prices are determined in various market settings.

Macroeconomics

Macroeconomics examines the overall performance and behavior of the entire economy.
It focuses on aggregate variables such as inflation, unemployment, GDP, and economic growth.
Macroeconomics uses models to analyze economic fluctuations and to develop policies to stabilize the economy.
The study involves understanding the relationships between various economic indicators.
It analyzes the factors influencing aggregate demand and aggregate supply.

Supply and Demand

Supply represents the quantity of a good or service that producers are willing and able to offer at different price levels.
Demand represents the quantity of a good or service that consumers are willing and able to purchase at different price levels.
The interaction of supply and demand determines the equilibrium price and quantity in a market.
Shifts in supply or demand curves cause changes in equilibrium.
Factors affecting supply include input costs, technology, and government regulations.
Factors affecting demand include consumer income, tastes, and prices of related goods.

Elasticity

Elasticity measures the responsiveness of one variable to changes in another.
Price elasticity of demand measures the percentage change in quantity demanded in response to a percentage change in price.
Income elasticity of demand measures the percentage change in quantity demanded in response to a percentage change in income.
Cross-price elasticity of demand measures the percentage change in quantity demanded of one good in response to a percentage change in the price of another good.
Understanding elasticity is crucial for businesses to make pricing and production decisions.

Market Structures

Perfect competition involves many buyers and sellers, homogeneous products, and free entry and exit.
Monopoly involves a single seller with no close substitutes.
Oligopoly involves a few large sellers who are interdependent.
Monopolistic competition involves many sellers with differentiated products.
Market structure affects pricing and output decisions of firms.

Production and Costs

Production involves transforming inputs (labor, capital, land) into outputs (goods and services).
Costs represent the expenses incurred in the production process.
Different cost concepts include total cost, fixed cost, variable cost, average cost, marginal cost.
Understanding production and cost is vital for firms to determine profitability.

Economic Growth

Economic growth refers to an increase in the production of goods and services in an economy over time.
It's measured by changes in real GDP.
Factors contributing to economic growth include technological progress, capital accumulation, and labor force growth.
Economic growth leads to improvements in living standards.

International Economics

International economics studies economic interactions among countries.
It focuses on trade, exchange rates, and international finance.
Concepts include comparative advantage, absolute advantage, and trade barriers.
It analyzes the effects of globalization on economies.
International trade allows countries to specialize in producing goods and services in which they have a comparative advantage.

Economic Systems

Economic systems are frameworks for organizing the production, distribution, and consumption of goods and services.
Different systems include capitalism, socialism, and mixed economies.
Capitalism is characterized by private ownership of resources, markets, and profit motives.
Socialism involves state ownership or control of resources and emphasis on social welfare.
Mixed economies combine elements of both capitalism and socialism.

Fiscal Policy

Fiscal policy involves government spending and taxation.
Expansionary fiscal policy aims to stimulate the economy by increasing government spending or decreasing taxes.
Contractionary fiscal policy aims to cool down an overheating economy by decreasing government spending or increasing taxes.
Fiscal policy tools are used to manage aggregate demand.

Monetary Policy

Monetary policy involves actions undertaken by a central bank to influence the money supply and credit conditions to stimulate or restrain economic activity.
Central banks use various instruments, including interest rates, reserve requirements, and open market operations.
Monetary policy is used to manage inflation and employment.
Central banks strive to achieve price stability.

Inflation

Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time.
It erodes the purchasing power of money.
Causes of inflation can include increased demand, rising input costs, and monetary factors.
High inflation can be harmful to economic stability.

Unemployment

Unemployment refers to the proportion of the labor force that is actively seeking work but unable to find employment.
Different types of unemployment exist, including frictional, structural, and cyclical unemployment.
Unemployment is a key indicator of economic health.
