Econ 152 Overview and Microeconomics Concepts

Overview of Econ 152

• Course Focus: Typically an introductory economics course, covering key microeconomic and macroeconomic principles.
• Goals: Understanding economic theories, market behavior, and the role of government in the economy.

Key Concepts in Microeconomics

1. Supply and Demand:

   • Law of Demand: As price decreases, quantity demanded increases.
   • Law of Supply: As price increases, quantity supplied increases.
   • Market Equilibrium: Where supply equals demand.

2. Elasticity:

   • Price Elasticity of Demand: Responsiveness of quantity demanded to price changes.
   • Types: Elastic (>1), Inelastic (<1), Unitary (=1).

3. Consumer Behavior:

   • Utility Maximization: Consumers seek to maximize satisfaction.
   • Budget Constraints: Limits on consumer choice based on income and prices.

4. Production and Costs:

   • Short-run vs. Long-run Costs: Fixed vs. variable costs.
   • Marginal Cost: Cost of producing one more unit.
   • Economies of Scale: Cost advantages as production increases.

5. Market Structures:

   • Perfect Competition: Many buyers/sellers, homogeneous products.
   • Monopoly: Single seller, unique product.
   • Oligopoly: Few sellers, interdependent pricing.

Key Concepts in Macroeconomics

1. Gross Domestic Product (GDP):

   • Definition: Total value of all goods and services produced within a country.
   • Components: Consumption, Investment, Government Spending, Net Exports.

2. Inflation:

   • Measurement: Consumer Price Index (CPI) and Producer Price Index (PPI).
   • Effects: Decreases purchasing power, impacts interest rates.

3. Unemployment:

   • Types: Frictional, Structural, Cyclical, Seasonal.
   • Natural Rate of Unemployment: The rate when the economy is healthy.

4. Monetary Policy:

   • Role of Central Banks: Control money supply and interest rates.
   • Tools: Open market operations, discount rate, reserve requirements.

5. Fiscal Policy:

   • Government Spending and Taxation: Tools to influence economic activity.
   • Budget Deficit vs. Surplus: Difference between government spending and revenue.

Economic Indicators

• Leading Indicators: Predict future economic activity (e.g., stock market performance).
• Lagging Indicators: Confirm trends after they occur (e.g., unemployment rate).
• Coincident Indicators: Occur simultaneously with economic trends (e.g., GDP).

Key Theories and Models

1. Classical Economics:

   • Belief in self-regulating markets and limited government intervention.

2. Keynesian Economics:

   • Emphasizes government intervention to stabilize the economy during recessions.

3. Monetarism:

   • Focus on controlling the money supply to manage economic stability.

Conclusion

• Understanding the interplay between micro and macroeconomic factors is essential for analyzing economic policies and market behavior.
• Econ 152 provides a foundation for further study in economics and related fields.

Overview of Econ 152

• Introductory economics course, focusing on principles of microeconomics and macroeconomics.
• Aims to develop an understanding of economic theories and market dynamics.
• Explores the role of government in influencing economic conditions and policies.

Key Concepts in Microeconomics

• Supply and Demand:

  • Law of Demand highlights that a decrease in price leads to an increase in quantity demanded, reflecting consumer behavior.
  • Law of Supply indicates that higher prices result in greater quantity supplied, suggesting producer incentives.
  • Market Equilibrium occurs at the point where the quantity supplied matches the quantity demanded, establishing market stability.

• Elasticity:

  • Price Elasticity of Demand measures how sensitive the quantity demanded is to changes in price; crucial for understanding consumer behavior and revenue implications.
  • Demand can be classified as Elastic (greater than 1) indicating that demand significantly reacts to price changes, or Inelastic (less than 1) suggesting minimal reaction to price fluctuations.
