Chapter 4 - The Market Forces of Supply and Demand Flashcards
What is a Market
Sellers (determine supply) and buyers (determine demand)
Competitive Market
Market with many buyers and sellers that are competing against each other, therefore they have a negligible impact on market prices.
Perfectly Competitive Market
- All the goods and services are the same
- So many buyers and sellers that there not one individual or firm that can have influence on market price
Price Takers
In a perfectly competitive market prices are determined by the forces of supply and demand. So, individuals and firms simply have to accept these prices therefore they are price takers.
Quantity of Demand
The amount that a buyer is willing and able to purchase
Law of Demand
When the price of a good or service increases, demand decreases and vice versa. (If all other factors are equal)
Demand Schedule
A table showing the relationship between price and quantity demanded if all other factors are held constant.
Normal Good
When demand for a good decreases when income decreases it is considered a normal good.
Inferior Good
When demand for a good increases when income decreases it is considered an inferior good. (ex. bus rides go up when income goes down because people cant afford individual transportation)
Income (Demand Shifts)
Income increase and decrease is what makes these goods normal or inferior. These goods aren’t always normal or inferior it depends on the situation (income)
Prices of Related Goods
The price of related goods affect the demand of other goods. Certain goods can be substituted with related goods, therefore shifting their demand curve. These goods are called substitutes. (ex. frozen yogurt and ice cream, or sweaters and hoodies)
Certain goods also incentivize the purchasing of another good that essentially pairs well with one another. These goods are called compliments. (ex. hot fudge and sprinkles - icecream, peanut butter - jelly)
Tastes
Tastes determine demand for any good. Peoples tastes are determined by historical and psychological factors.
Expectations
Demand can also be determined and changed by peoples expectations. When people expect or don’t expect certain things they will spend less or more. (ex. knowing you’ll have a higher paycheque next month can adjust spending habits and therefore shift the demand curve)
Number of Buyers
The higher the number of buyers in a certain market (buying a specific good or service) the higher the demand. (simple math)
Shifts in Demand Curve
All changes besides a price change are factors that shift the demand curve.
