Chapter 3: Law of Demand and Supply Flashcards
refers to the quantity of a product, item, commodity, or service that suppliers are willing to make available at a given price.
Supply
refers to the quantity of a product, item, commodity, or service that consumers are willing and able to acquire available at a given price.
Demand
The blank is one of the most fundamental economic laws that are blank to practical ideas.
law of supply and demand
inextricably linked
A group of buyers and sellers of a particular good or service.
Market
A market in which there are many buyers and many sellers so that each has a negligible impact on the market price.
Competitive Market
A market that has only one seller
Monopoly
The amount of good that buyers are willing and able to buy at a certain price level
Quantity Demanded
The result of the Law of demand: individuals would blank a commodity that requires them to blank of another item they value more.
naturally avoid purchasing
forego the consumption
The claim that other things being equal, the quantity demanded of a good falls when the price rises, and vice versa.
Law of demand
A table in economics that depicts the quantity demanded on an item or service at various price levels.
Demand Schedule
A graph of the relationship between the price of a good and the quantity demanded
Demand Curve
Sum of individual demand curves
Market demand
Determinants of Demand that shifts the demand curve
- Consumer’s Income
- Consumer’s Expectations of Future Prices
- Prices of Related Products
- Consumer’s Taste and Preference
- Population
How does consumers’ income affect demand?
Because your income dictates the way you spend your money
demand increase when income increases and vice versa, the good is called?
normal goods
demand falls when income rises and vice versa, the good is called?
inferior goods
Example of normal goods
Basic necessities such as rice, utilities, medical and dental services
Example of inferior goods
A lower income person chooses public transportation than acquiring cars, and if a person has a higher income, he tends to buy cars rather than choosing public transportation.
How does Consumer’s Expectations of Future Prices affect demand?
Expecting prices in future periods affect the way we spend currently, therefore, affecting the demand
Example of Consumers’ Expectations
increase on the price of gasoline in the future causes panic-buying for car owners to maximize their purchasing power.
How do Prices of Related Products affect demand?
Demand for a particular good will change the demand for related goods
Types of Related Products according to availability
Substitute
Complimentary
two goods for which an increase in the price of one leads to an increase in the demand of the other,
Goods used in place for other goods
Substitute
two goods for which an increase in the price of one leads to a decrease in the demand of the other,
Goods that cannot be used without the other
Complimentary
Example of Substitute
Frozen Yogurt and Ice cream
Example of Complements
Gasoline and Automobiles
The most obvious determinant of demand
Consumer’s Taste and Preference
How do Consumers’ Tastes and Preferences affect demand?
Because an inclination toward a good affects demand
Determinant of demand that is affected by religion, culture, age, traditions, trend, technology, and other historical and psychological forces.
Consumer’s Taste and Preference
How does Population affect demand?
An increase in population also increases the demand because there will be another addition to the market demand.
The mathematical representation of the relationship between the quantity good sought and the factors that affect the consumers’ willingness and capacity to purchase the good.
Demand Function
Demand Function
Qd=f(P,Prg,Y)
Qxt=f(Pxt,Yt,Prt,P^e(x,t+i),T)
Qdx = a - bPx
The variables in the right are being held blank as the demand curve is plotted
constant
If it is a compliment, its price coefficient will be blank. If it is a substitute, its price coefficient will be blank.
negative
positive
The coefficient of income is positive indicate that it is blank. If the coefficient is negative, the good is blank.
normal good
inferior good
Blank is driven by demand.
Economic growth
Governments and central banks stimulate demand in order to bring blank to an end.
recessions
However, economics simplifies the equation to emphasize the blank of individual demand and the sixth factor of blank.
five key drivers
aggregate demand
the number of goods or services that suppliers are willing to produce at a given market price.
quantity supplied
The claim that, other things being equal, the quantity supplied of a good rises when the price of the good rises.
Law of Supply
a table that shows the relationship between the price of a good and the quantity supplied
Supply Schedule
A graph of the relationship between the price of a good and the quantity supplied
Supply Curve
The sum of the supplies of all sellers.
Market Supply
Determinants of supply that shifts the supply curve
Input Prices, Technology, Expectations, Number of Sellers, Government Regulations (Tax, subsidies, and policies)
How do Input Prices affect supply?
Increases in the price of the raw materials in order to produce outputs affect the ability of a firm to produce.
How does Technology affect supply?
Technological advancements could reduce firms’ costs and could produce more outputs.
How do Expectations affect supply?
Increase in future price could make producers manufacture less in the current period and produce more at a future period.
How does Number of Sellers affect supply?
An increase in the number of sellers means that the supply will increase in the market and if the number of sellers decreases it will prove otherwise.
How do Government regulations (Tax, subsidies, and policies) affect supply?
Taxes and regulations hinder firms to produce more outputs and subsidies encourages firms to produce more.
a situation in which the market price has reached the level at which quantity supplied equals quantity demanded
Market equilibrium
A mathematical representation of the relationship between the quantity of a service or product required, its price and other associated factors.
Supply Function
Supply Function
Qsx = f(P_x,T,C,Exp,Grt,Gs,M) Qsx = f(Px) Qsx = -c + dPx
The supply of a good is blank to the prices of inputs used to make the good.
Negatively related
Machinery or other technologies reduce what?
Cost and Labor
Change in Demand
Shifts demand curve to another.
Changes in Quantity Demand
Movement along the curve as other remain variables remain constant.
The degree to which the quantity fluctuates in response to variations in price is called?
Demand Elasticity
Change in Supply
Shifts supply curve to another.
Changes in Quantity Supplied
Movement along the supply curve as other variables remain constant.
A situation in which quantity supplied is greater than quantity demanded.
Surplus
Also called excess supply
Surplus
A situation in which quantity demanded is greater than quantity supplied.
Shortage
Also called excess demand
Shortage
The claim that the price of any good adjusts to bring the quantity supplied and the quantity demanded that good into balance
