Study Notes

Microeconomics for Business - Part 2: Market Forces

The "market" is the total supply and demand for a specific product.
Not all markets function the same way. Market structures vary based on the number of competitors and the type of product.

Market Structures

Number of Competitors:
- Monopoly: one supplier
- Duopoly: two suppliers
- Oligopoly: few suppliers
- Competition (perfect or monopolistic): many suppliers
Type of Product:
- Homogeneous: products are virtually identical (e.g., gasoline, wheat).
- Heterogeneous: products are perceived as clearly different (e.g., clothing, restaurants)

Ideal Market Conditions

No Market Power: Buyers and sellers have no significant influence on prices.
Private Goods and No Externalities: Goods are privately consumed, and there are no external effects.
Symmetric Information: Buyers and sellers have the same information about the goods and services.

Perfectly Competitive Market

Many buyers and suppliers (market atomism)
Each supplier has negligible influence on the price (price takers)
Homogeneous good/service
Consumers only consider price.
Examples: Milk market in Europe (price takers), Belgian Telecom market (price makers)

3.2 Demand as an Expression of Willingness to Pay

Demand for a product is a function relating quantity demanded to price.
Reservation price (critical price): The maximum price a consumer is willing to pay for a good or service.
Maximum willingness to pay might differ among consumers due to preferences or income.
Demand for Sandwiches: The demand function describes how the total quantity of sandwiches demanded relates to their price.
Law of Demand: Quantity demanded tends to decrease as the price increases (inverse relationship).
Types of goods (exceptions to Law of Demand): Giffen goods (see chapter 6)
Consumer surplus: The difference between the maximum willingness to pay and the actual price paid.
- Total consumer surplus: sum of all individual consumer surpluses.

3.3 Supply as an Expression of Marginal Costs

Supply function: depicts how the total quantity of a good supplied relates to its price.
Reservation price/critical price: The minimum price a seller is willing to accept for a good.
Reservation prices can differ amongst sellers due to cost variations.
Law of Supply: Quantity supplied increases as the price increases.
Producer surplus: the difference between the price received and the minimum price the seller would accept.

3.4 Pricing

Equilibrium price: The market price where the quantity demanded equals the quantity supplied.
Equilibrium quantity: The quantity of a good or service traded at the equilibrium price.
Graphically: The equilibrium is the intersection point of the supply and demand curves.
Mathematically: Set the demand equation equal to the supply equation and solve for the price.

Price Dynamics (+/- changes)

Excess Supply (Supply Surplus): Price is higher than the equilibrium price. Suppliers offer more than consumers want, causing price to fall to equilibrium.
Excess Demand (Demand Surplus or Shortage): Price is lower than the equilibrium price. Consumers want more than suppliers supply, causing price to rise to equilibrium.

Signal Function of Prices

Prices signal profitability to producers, and consumer needs to a good or service.
Rising prices signal shortage & high profitability to producers, and consumers willing to pay higher price, to buy more.
Falling prices signal surplus & low profitability to producers, and lower costs to consumers in the market.

Changes in Market Equilibrium

Three steps to analyze changes in equilibrium:
Identify if the change affects demand or supply (or both)
Determine the direction of the shift.
- Is it a positive or negative demand/supply shock?
- Which way does the line shift?
Use a graph to evaluate the new equilibrium (price & quantity).
Use Comparative Statics: Comparing equilibrium points before and after the event. Don't describe the transition between equilibria.

Other Demand Shocks:

Cyclical patterns (daily, weekly, annual), long-term (perennial), social developments, one-time events.

Types of Demand Shocks:

Impact of prices of other goods
Goods can be substitutes or complements. Substitutes satisfy the same needs (e.g., coffee vs tea). Complements need to be used together (e.g., printer & ink cartridge)
Impact of income
Normal goods: demand increases with higher income. Inferior goods: demand decreases with higher income
Impact of preferences, tastes, expectations, and advertising Preferences and tastes are the basis for consumer behavior. Expectations of future events, like prices changes or income changes, impact current demand. Advertising influences consumer tastes and preferences.

Types of Supply Shocks:

Impact of input (e.g., raw material) prices. Changes in input prices affect production costs and therefore supply.
Impact of technology, natural/social factors such as weather. Changes in technology may cause a supply shock. Weather or other natural or social events can affect supply.

Additional Points

Market equilibrium summary: supply and demand intersect to determine price
Economists are less interested in tastes, but more in the reactions to taste changes.
