Fundamentals of Economics Flashcards
Define Buyers and Sellers (Market Participants)
Refers to who is included and who is excluded from a particular market
What do Market Participants do?
Households, Firms, or Government that…
Provide Demand - Those who buy Goods and Services
Provide Supply - Those who sell goods and services
What is Demand
How much people want to buy.
What are the “determinates of demand”
Price
Tastes (preference)
Income
Related goods (Substitute Items)
Future Price Expectation
What makes up the Demand Function?
(Qd - function(Pi, Y, T, Ps, Pc, Pe)
Quantity = the function of (Price of an item, Income, Tastes (preferences), price of substitutions, price of compliment items, price expected)
What is Quantity Demanded
The amount of a good or service that people are willing and able to buy at various prices, (centers paribus)
What is the Law of Demand
Price and Quantity demanded are negatively related, centers parades
as prices rise, quantity demanded drops and visa versa.
Market Demand Curve
Will be a downscoping line that is the Sum of all individual demand curves at each price
What defines an increase in demand
Any change in the world (Other than price) that will cause people to want to buy more of the good or service)
(Same line slope shifts to the right)
What defines a decrease in demand
Any change in the world (other than price) that will cause people to want to buy less of the good or service
(Same line slops shifts to the left)
What is Elasticity
Measure of the responsiveness of one variable to changes in another variable.
The Sensitivity of one variable when related to variable changes value
Specifically, it measures the % change in one variable when another variable changes by 1%
What is Own Price Elasticity?
The % Change in Qd (demand) in response to a 1% Change in price of the product
What is Cross Price Elasticity
The % Change in Qd (demand) in response to a 1% Change in the Price of a related good
What is Income Elasticity
The % change in Qd(demand) in response to a 1% Change in income
What is Price Elasticity of Demand (Ed)
The responsiveness of Qd (demand) to changes in P (Price)
Ed = ((%change Qd) / (%change P))
What are the three possible relationships between Qd (demand) and P (price)
Elastic - Responsive
Inelastic - Unresponsive
Unit Elastic - Change is the same percentage
Calculating Elasticity
Arc Method
Ed = %change Q / %change P
%change Q = (Change in Qd / Average Qd) x 100
%change P = (Change P / Average P) x 100
What does price elasticity of demand mean for me and my business?
What will happen to my total revenue if I change price?
Revenue Formula
Revenue = Price * Quantity
What is Supply
How many units you want to produce
What are the determinants of supply?
Price
Technology of production
prices of inputs
Expected future price of the good
What makes up the supply Function?
Qs = function(Pi, A, Pinputs, Pe)
Quantity of Supply
Price of the item
Technology (A)
Price of Inputs
Expected future Price
