Study Notes
Property Rights and Market Failure
- Property rights enable individuals to own and control scarce resources.
- Market failure occurs when resources are not allocated efficiently, prompting potential government intervention to enhance efficiency and equity.
- Externalities occur when one party's actions affect the well-being of a bystander, leading to market failure.
- Market power arises when a single entity can significantly influence market prices.
Economic Terminology
- Key economic terms include:
- Supply
- Opportunity Cost
- Elasticity
- Consumer Surplus
- Demand
- Comparative Advantage
- Deadweight Loss
Economic Thinking
- Economics encourages analysis of alternatives and assessment of costs associated with individual and societal choices.
- Understanding how events and issues interconnect is vital in economic analysis.
The Economist as a Scientist
- Economic analysis involves objective and analytical thinking, scientific methods, and the utilization of abstract models to explain complexities of reality.
- Economists develop theories, collect data, and evaluate hypotheses to understand economic phenomena.
Assumptions in Economics
- Assumptions help simplify complex realities, enabling economists to better grasp specific issues.
- Different assumptions may be required to address varying economic questions.
Economic Models
- Models are essential tools that enable economists to simplify real-world scenarios for greater comprehension.
Demand Curve Dynamics
- Demand shifts:
- Increased consumer income results in higher demand for normal goods, and decreased demand for inferior goods.
- Changes in the prices of related goods can categorize products as substitutes or complements depending on their demand response.
Market Supply vs. Individual Supply
- Market supply aggregates individual supply from all sellers of a good or service, depicted graphically by summing individual supply curves horizontally.
Shifts in the Supply Curve
- Supply can shift due to various factors such as changes in input prices, technological advancements, seller expectations, and the number of sellers in the market.
Price Elasticity of Demand
- Price elasticity measures how responsive the quantity demanded is to price changes, defined as the percentage change in quantity over the percentage change in price.
- Demand can be classified as elastic (sensitive to price changes) or inelastic (insensitive to price changes).
Market Implications
- A significant increase in supply can lead to price drops, particularly when demand is inelastic.
- Analyzing changes in supply and demand curves is crucial to understanding shifts in market equilibrium.
OPEC and Oil Prices
- OPEC's challenges in maintaining high oil prices arise from the contrasting elasticity of supply and demand in the short run compared to the long run.
Types of Demand Curves
- Demand curves can vary significantly:
- Perfectly Inelastic: Quantity demanded remains constant regardless of price changes.
- Perfectly Elastic: Quantity demanded reacts infinitely to price changes.
- Unit Elastic: Quantity demanded changes by the same percentage as price changes.
Understanding Elasticity
- Price elasticity of demand is correlated with the slope of the demand curve but is not equivalent to it.
- Comparative analysis of different demand curves reveals varying sensitivities to price changes, emphasizing the importance of elasticity in economic analyses.
