Demand
The quantity of goods that consumers are willing and able to buy at various prices during a given period of time
Demand schedule
A table showing the quantity demanded of a good or service at different price levels
Demand function
A mathematical equation expressing the demand of a product or service as a function of its price
Change in QD
New QD minus Old QD
Change in Price
New Price minus Old Price
Demand Curve
A graphical illustration of the demand schedule, with Price on the vertical axis (Y) and Quantity Demanded on the horizontal axis (X). It slopes downward indicating the negative relationship between price and quantity demanded
There is an inverse relationship between the prices of a good and the quantity demanded. As price increases, quantity demanded decreases and vice versa
Non-price Determinants of Demand
Income, taste, expectations, prices of related goods, population
Shift of the demand curve
A change in the entire demand for a product caused by non-price determinants
Supply
The quantity of goods that sellers are willing and able to offer for sale at various prices
Non-price determinants
Can cause an upward or downward change in the entire demand for the product, referred to as a shift of the demand curve
Demand function
D= f(Y,T,E,PR,P) - Demand for a good is a function of Income (Y), Taste (T), Expectations (E), Price of Related Goods (PR), and Population (P)
Supply
The quantity of goods that sellers are willing and able to offer for sale at various prices during a given period of time
Supply schedule
A table that shows the quantity supplied at each price
Supply function
A mathematical equation expressing the quantity of a commodity supplied as a function of the commodity's price, e.g., Qs= a+b(P) where a is the x-intercept, b is the slope (Change in QS/Change in Price), and P is the price
Supply Curve
A graphical illustration of the demand schedule, with Price measured on the vertical axis (Y) and Quantity Supplied measured on the horizontal axis (X)
Demand curve slopes upward
Indicating the positive relationship between price and quantity supplied
Change in QS
New QS - Old QS
Change in Price
New Price - Old Price
