What this chapter covers: This chapter introduces the fundamental concepts of economics, including scarcity, choice, opportunity cost, supply and demand, and elasticity. It lays the groundwork for understanding how markets function and how economic decisions are made.
| Concept/Event | Significance | Key Evidence |
|---|---|---|
| Scarcity | Basic economic problem | Limited resources, unlimited wants |
| Opportunity Cost | Value of next best alternative | Making choices involves trade-offs |
| Law of Demand | Inverse relationship between price and quantity demanded | Demand curve slopes downward |
| Market Equilibrium | Where supply equals demand | Determines price and quantity |
| Price Elasticity of Demand (PED) | Responsiveness of quantity demanded to price changes | % change in quantity demanded / % change in price |
❌ Mistake: Confusing movement along the demand curve with a shift of the demand curve. ✅ How to avoid: Remember that changes in price cause movement along the curve, while changes in other factors (income, tastes, etc.) cause the entire curve to shift.
What this chapter covers: This chapter explores different market structures, including perfect competition, monopolistic competition, oligopoly, and monopoly. It analyzes the characteristics of each structure and their implications for prices, output, and efficiency.
| Concept/Event | Significance | Key Evidence |
|---|---|---|
| Perfect Competition | Many small firms, homogeneous product | Price takers, zero economic profit in long run |
| Monopolistic Competition | Many firms, differentiated products | Some market power, zero economic profit in long run |
| Oligopoly | Few large firms, interdependent decisions | Strategic behavior, collusion possible |
| Monopoly | Single firm, unique product | Price maker, positive economic profit in long run |
| Barriers to Entry | Factors preventing new firms from entering a market | High start-up costs, patents, government regulations |
❌ Mistake: Assuming all firms in an oligopoly will collude. ✅ How to avoid: Recognize that collusion is difficult to maintain due to incentives to cheat.
What this chapter covers: This chapter introduces key macroeconomic indicators such as GDP, inflation, unemployment, and economic growth. It also covers the Aggregate Demand-Aggregate Supply (AD-AS) model.
| Concept/Event | Significance | Key Evidence |
|---|---|---|
| Gross Domestic Product (GDP) | Measure of aggregate output | Expenditure, income, or output approach |
| Inflation | Sustained increase in price level | Measured by Consumer Price Index (CPI) |
| Unemployment Rate | Percentage of labor force unemployed | Frictional, structural, cyclical, seasonal |
| Economic Growth | Increase in real GDP | Shifts in LRAS curve or PPC |
| AD-AS Model | Analyzes relationship between aggregate demand and aggregate supply | Equilibrium price level and real GDP |
❌ Mistake: Confusing nominal GDP with real GDP. ✅ How to avoid: Remember that real GDP is adjusted for inflation, while nominal GDP is not.
