Introduction to Economics

Definition of Economics

• Economics: The study of how individuals and societies allocate scarce resources to satisfy unlimited wants.

Major Branches

1. Microeconomics

   • Focuses on individual consumers and businesses.
   • Examines supply and demand, price formation, and consumer behavior.

2. Macroeconomics

   • Looks at the economy as a whole.
   • Analyzes overall GDP, inflation rates, unemployment, and national policies.

Key Concepts

• Supply and Demand: Fundamental concept determining the price of goods and services in a market.
• Market Equilibrium: The point where supply equals demand.
• Elasticity: Measures responsiveness of quantity demanded or supplied to price changes.
• Opportunity Cost: The potential benefit lost when choosing one alternative over another.

Economic Systems

• Capitalism: Private ownership of resources; market-driven economy.
• Socialism: Government ownership and regulation of resources; aims for equal distribution.
• Mixed Economy: Combination of capitalism and socialism.

Economic Indicators

• Gross Domestic Product (GDP): Total value of goods and services produced in a country.
• Inflation Rate: Percentage rise in the general price level of goods and services.
• Unemployment Rate: The share of the labor force that is jobless and actively seeking employment.

Types of Markets

• Perfect Competition: Many sellers, identical products; no market power.
• Monopoly: Single seller controls the market; high market power.
• Oligopoly: Few sellers, products may be identical or differentiated; interdependent pricing.

Business Cycles

1. Expansion: Economic growth; rising employment and production.
2. Peak: Maximum output; economy operates at full capacity.
3. Recession: Decline in economic activity; falling GDP and employment.
4. Trough: Lowest point; recession ends and recovery begins.

Fiscal and Monetary Policy

• Fiscal Policy: Government spending and tax policies to influence the economy.
• Monetary Policy: Central bank's actions (interest rates, money supply) to control inflation and stabilize currency.

International Economics

• Trade Balance: Difference between exports and imports.
• Exchange Rates: The value of one currency for the purpose of conversion to another.
• Globalization: Increasing interconnectedness and interdependence of economies worldwide.

Economic Theories

• Classical Economics: Markets function best without intervention; supply creates its own demand.
• Keynesian Economics: Advocates for government intervention to manage economic cycles.
• Supply-Side Economics: Focus on boosting supply; tax cuts and deregulation to stimulate production.

Conclusion

• Economics affects decision-making at individual, corporate, and governmental levels.
• Understanding basic economic principles is crucial for navigating financial and business environments.

• Inflation Rate is the percentage increase in the general price level of goods and services.
• Unemployment Rate represents the portion of the labor force that is jobless and actively seeking employment.

Types of Markets

• Perfect Competition features many sellers offering identical products, with no individual having market power.

• Oligopoly involves a few sellers who may offer identical or differentiated products, with interdependent pricing strategies.

Business Cycles
