Microeconomics Overview

Study Notes

Economics

Economics is the social science that studies how societies allocate scarce resources to satisfy unlimited wants and needs.
It's divided into two major branches: microeconomics and macroeconomics.

Microeconomics

Microeconomics focuses on the behavior of individual economic agents, such as households and firms.
It examines how these agents make decisions in the face of scarcity and how their decisions interact in specific markets.
Key concepts include supply and demand, market equilibrium, elasticity, production costs, market structures (perfect competition, monopoly, oligopoly, monopolistic competition), and consumer choice theory.
Supply and demand determine the price and quantity of goods and services in a market.
Elasticity measures the responsiveness of quantity demanded or supplied to changes in price or other factors.
Production costs are the expenses incurred by firms to produce goods and services.
Market structures describe the characteristics of markets based on the number and size of firms.
Consumer choice theory examines how consumers make decisions to maximize their utility.
Externalities, like pollution, can affect the efficiency of markets and lead to market failures.
Market failures are situations where markets fail to allocate resources efficiently.
Public goods, like national defense, are goods that are non-excludable and non-rivalrous, hence, often requiring government intervention.
Governments use policies like taxes, subsidies, and regulations to influence market outcomes.

Macroeconomics

Macroeconomics studies the behavior of the entire economy, including aggregate variables such as inflation, unemployment, and economic growth.
It examines the interactions between different sectors of the economy, such as households, firms, and governments.
Macroeconomic objectives include promoting economic growth, reducing unemployment, and controlling inflation.
Key macroeconomic concepts include Gross Domestic Product (GDP), inflation rate, unemployment rate, aggregate demand and aggregate supply, fiscal policy, and monetary policy.
GDP measures the total value of goods and services produced in an economy over a period of time.
Inflation is a general increase in the overall price level of goods and services.
Unemployment refers to the percentage of the labor force that is actively seeking employment but unable to find it.
Aggregate demand and aggregate supply are models that visualize how total supply and demand from all market sectors in an economy influence the overall price and output levels.
Fiscal policy refers to the government's use of taxation and spending to influence the economy.
Monetary policy refers to the actions taken by the central bank to influence the amount of money and credit in the economy.
Business cycles are fluctuations in economic activity characterized by periods of expansion and contraction.
Economic growth refers to an increase in the production of goods and services in an economy over time.
International trade and exchange rates are crucial factors in macroeconomics; they heavily influence price levels and can lead to trade deficits or surpluses.
Economic development is a broader concept than economic growth, including factors like poverty reduction and improving living standards.
