VERTICAL ADDITION: In graphical analysis, the technique of combining two curves by adding the value of the variable on the vertical or Y axis for a given value of the variable on the horizontal or X axis. This is commonly used for deriving the demand curve for a public good from a set of individual demand curves. The demand price that each individual buyer is willing to pay is added for a given quantity to identify the total benefits obtained.

An increase in demand caused by one of the demand determinants.- Initial equilibrium market at price Po and quantity Qo
- Buyers acquire a sudden "appetite" for hot fudge sundaes.
A summary: - The demand curve shifts rightward.
- The initial equilibrium is no longer an equilibrium.
- The new equilibrium is at the intersection of the original supply curve with the new demand curve.
- New equilibrium price is P1 and new equilibrium quantity is Q1.
The six steps of market adjustment for an increase in demand:- A determinant changes. We have a greater appetite for hot fudge sundaes.
- A curve to shifts. The demand curve for hot fudge sundaes shifts rightward.
- A shortage or a surplus occurs. The increase in demand causes a shortage of hot fudge sundaes.
- The price changes. The price of hot fudge sundaes goes up.
- The quantities demanded and supplied change. The quantity supplied for hot fudge sundaes increases while their quantity demand is reduced.
- The market imbalance is eliminated and equilibrium is restored. The shortage of hot fudge sundaes is eliminated. The price is higher and the quantity exchanged is more.

[What's This?]
Today, you are likely to spend a great deal of time driving to a factory outlet hoping to buy either a microwave over that won't burn your popcorn or a T-shirt commemorating the first day of winter. Be on the lookout for empty parking spaces that appear to be near the entrance to a store.
