Supply and Demand
- Supply: Quantity of goods/services available.
- Demand: Desire for goods/services and the ability to pay.

- Command: Central authority makes decisions.
- Market: Decisions based on supply and demand.
- Mixed: Combination of market and command elements.

Economic Indicators

- Management of money supply and interest rates by central banks.
Fiscal Policy
- Government spending and tax policies to influence the economy.

Economic Theories

Classical Economics

Keynesian Economics
- Advocates for government intervention to manage demand and smooth economic cycles.
Supply-Side Economics
- Emphasizes boosting supply through tax cuts and deregulation.

Current Issues in Economics

Globalization and trade policies.
Income inequality and wealth distribution.

Definition of Economics

Economics studies how societies allocate scarce resources to meet unlimited wants.
It examines the processes of production, distribution, and consumption concerning goods and services.

Major Branches of Economics

Microeconomics
- Focuses on the behavior and decision-making of individual consumers and businesses.
- Analyzes supply and demand dynamics, price setting, and consumer purchasing habits.
Macroeconomics
- Examines the economy in its entirety, considering aggregate measures.
- Key indicators include Gross Domestic Product (GDP), unemployment rates, inflation, and national income.

Key Concepts

Scarcity
- Represents the limited availability of resources in comparison to infinite consumer desires.
Opportunity Cost
- Refers to the value of the next best alternative that is lost when a decision is made.
Supply and Demand
- Supply indicates the total quantity of goods or services available for purchase.
- Demand expresses consumers' willingness and ability to buy those goods or services.
Market Equilibrium
- The condition where supply equals demand, which helps in determining the market price.
Economic Systems
- Traditional: Relies on customs and historical practices.
- Command: Central authority dictates resource allocations and production.
- Market: Decisions are influenced by supply and demand dynamics.
- Mixed: Combines elements of both market and command systems.

Economic Indicators

Gross Domestic Product (GDP)
- Measures the total monetary value of all finished goods and services produced within a country over a specified period.
Unemployment Rate
- Indicates the percentage of the labor force that is jobless yet actively seeking employment.
Inflation Rate
- Represents the pace at which the overall level of prices for goods and services is rising, eroding purchasing power.

Types of Economic Policies

Monetary Policy
- Consists of measures implemented by central banks to control money supply and interest rates.
Fiscal Policy
- Involves government spending decisions and tax strategies aimed at influencing economic performance.

Economic Theories

Classical Economics
- Advocates for minimal government intervention, believing that free markets can self-regulate.
Keynesian Economics
- Promotes proactive government involvement to manage economic demand and mitigate downturns.
Supply-Side Economics
- Focuses on enhancing economic growth by reducing taxes and deregulation to boost production capabilities.

Current Issues in Economics

Globalization influences interwoven trade policies and international market dynamics.
Income inequality raises concerns regarding wealth distribution and economic fairness.
Environmental sustainability impacts economic practices and resource management.
Technology's role in disrupting labor markets and enhancing productivity is a growing focus.
