Miguel's Model of the Real Estate Market and Price Elasticity
This model represents the real-estate market, and the processes and variables in play which influence thatfocus on the effects of Price on the Elasticity of Supply and Demand.
The law of supply and demand states that when there is a high demand for a good or service. The price of the good or service rises. If there is a large supply of good or service but not enough demand for the good or service, the price falls.
The price elasticity of supply is used to see how sensitive
the supply of a good is to a price change. The higher the price elasticity the
higher the sensitivity to price change. A Low price elasticity implies that
changes in price have little influence on supply.
The price elasticity of Demand is used to see how sensitive the demand for a good is to a price change. The higher the price elasticity, the more sensitive to price changes. A Low price elasticity implies that changes in price have little influence on demand.

Important Variables and Stocks Involved
Old Quantity of Supply
%Change in Quantity Supply
HousesforSale
Old Quantity of Demand
%Change in Quantity Demand
WantingToBuy
Price Elasticity of Supply
Price Elasticity of Demand
%Change in Price
Old Price
New Price
-------------------------------------------------------------------
Within this model to calculate the price elasticity of supply, the percentage change is first calculated using the Old quantity and New quantity (HousesForSale).
This percentage change is then divided by the percentage change of the Old Price and New Price to obtain the Price Elasticity of Supply.
Similarly to calculate the price elasticity of demand, the percentage change is calculated using the Old quantity of demand and New quantity of demand (WantingToBuy).
This percentage change is then divided by the percentage change in price to obtain the Price Elasticity of Demand.
With the slider variables that can be changed are the Old Price and New price which affect the percentage change in price.
The percentage change in price then affects the Price Elasticity of Supply and Demand as it is used in conjunction with the %Change in quantity of Supply and Demand to obtain a value.
If we set the settings and simulate to:
Old Price = 500('000)
New Price = 250('000)
Old Quantity of Supply = 100
HousesforSale (New Quantity of Supply) = 50
Old Quantity of Demand = 10
WantingToBuy (New Quantity of Demand) = 5
We can see that the Demand is a lot higher because the the houses are half the price than the old price.
If we use these settings:
Old Price = 250('000)
New Price = 500('000)
Old Quantity of Supply = 50
HousesforSale (New Quantity of Supply) = 25
Old Quantity of Demand = 25
WantingToBuy (New Quantity of Demand) = 10
We can see that the supply is a lot higher than demand as the new price is twice the amount of the old price.
-------------------------------------------------------------------
With the sliders, these values can be adjusted to see the affect on the Price Elasticity of Supply and Demand.
This Model should have included its effect on the price however, was not added due to problems finding the right equation.
Assignment 3: Complex Systems

Retail Re-state
Market
Insight Maker is a program that allows users to
create complex interactions among industry or social factors. This program was used to model
the relationships among different players in the real estate market.
This model shows the effects
of changes in supply and demand, demand price and supply cost, availability of
houses and houses prices on the Retail Re-state Market. Each simulation can be
focused on how either Demand, Supply, supply cost, demand price, interest rate
and availability of houses interacts with one another over time.
Demand, Demand Price, Supply, Supply Cost, Interest
Rate, House Market and Houses Prices can be all adjusted by the user using the
sliders [Slider Value 0-100 (000 000
value)] except for interest rate where it limited to 0-0.10. Allowing the user to simulate different scenarios
and view changes in the market.
For Example: A slight change in House Prices will affect the Availability of Houses, House Price and the Supply and Demand dramatically.
When Supply increases, the availability of houses increases while Demand decreases.
Fixed variables/relationships:
Buyer Growth Rate, the Demand Price, Price Demand, Price Decrease, Supply Rate, Supply Price, Price Supply, Price Decrease.
These variables/relationships are shown on yellow. Fixed refers to no adjustments or changes is allow to those specific variables/relationships by the non -editor viewer. These variables cannot be change or adjusted as these variables/relationships are directly related to the information produced. With any changes to the fixed variables/relationships, it can cause incorrect simulation of the model to viewers.
Supply/Supply Cost has a direct relationship to one another as one variable increases the other one decreases. Demand and Demand Price has an inversely relationship related to Price.
House Price is the main reason why someone would sell or buy a house. Price is made up of various different factors. Demand price, demand, supply cost and supply are the main reasons houses price fluctuates.
Availability of Houses is simply New houses and houses Sold, based on If statements, If Demand=>Supply or If Supply <= Demand, the quantity will adjusted to meet the Demand and Supply levels.
Houses Price is simply House Price Increase and Houses Price decrease, based on if statements, If Demand=>Supply Cost or If Supply Cost <= Demand Price, the price will be adjusted to meet the Demand and Supply price.
Interesting Parameter:
This point is interesting
because it shows greatest fluctuations. You will see in Price Impact on
Demand/Supply display when house prices increases, supply will increase while
demand will decrease, as people are less willing to purchase a house at that
price due to high cost vice versa. Market availability and prices, as
availability of houses increases there is a decrease in houses prices causing
excess of supply, leading to an increase in demand as people are more willing
to purchase properties when prices are lower vice versa. Construction shows availability
of new houses, over time houses are sold, when sold houses hits zero, new
houses will increase as there will be a deficient of supply vice versa.
Setting Demand at 100
Setting Demand Price at 100
Supply at 50
Supply Cost 60
Availability of Houses 100
House Prices 85
Interest Rate 0.05
Notes:
There is a slight delay when a change variable is changed in this model. This represents the real market as a change in price, demand or supply doesn’t translate to an immediate action on the market as shown by this model.
