When the price of a complementary product for the demand for the other product will?

Complementary goods

Two products for which the demand schedules are related to each other so that an increase in the price of the first good will cause a leftward shift of the entire demand schedule for the other good(s) -- that is, less of the second good will now be demanded at any given available price of the second good. (By the same token, a decrease in the price of the first good will result in a rightward shift of the entire demand schedule for the other good(s), so that more of the second good will now be demanded at any given available price for the second good.) This complementarity commonly happens when the two goods tend to be consumed or used together in relatively fixed or standardized proportions in at least some of their important uses.

A classic example of complementary consumer goods would be frankfurters and hot dog buns. If a supermarket runs a "special" on hot dog buns, it is predictable that customers will want to buy more frankfurters than they otherwise would at whatever is the posted price of frankfurters -- because the total price of enjoying a frankfurter- on-a-bun sandwich is now lower than before due to the special, leading consumers to consume more of both component products.

A classic example of complementary producers' goods would be iron ore and coking coal, the two main raw materials for making steel. If the price of iron ore goes up, raising the steel companies' costs for making any given amount of steel, ceteris paribus, they are apt to cut back on the total quantity of steel they choose to produce. But if they decide to produce less steel, they will now need to buy less coal -- and therefore the amount of coal demanded at any given price of coal will be less than before the iron ore price increase. (The same complementarity with iron ore would also be evident with regard to all the other factors of production besides coal that are used in making steel -- such as labor-hours of steel workers, steel making machinery etc. The demand curve for each of them will shift to the left in response to increases in the price of coal or any of their other complementary goods or services.)

Chapter 3 Outline
I. DEMAND AND SUPPLY ANALYSIS
A. General Definitions and Comments
1. The law of demand states that consumers will purchase more of a good at lower prices and less of a good at higher prices.
2. The law of supply states that producers will sell less of a good at lower prices and more of a good at higher prices.
3. Equilibrium exits when there is no reason for a situation to change.
a. When equilibrium exits, the quantity people plan to buy is equal to the quantity that producers plan to sell.
b. The laws of demand and supply cause the market to move to equilibrium.
B. Other Demand Factors
1. Changes in demand factors other than price of the good will result in achange in demand.
a. An increase in demand is depicted as a rightward shift of the demand curve.
b. An increase in demand means that consumers plan to purchase more of the good at each possible price.
c. A decrease in demand is depicted as a leftward shift of the demand curve
d. A decrease in demand means that consumers plan to purchase less of the good at each possible price.
2. The price of related goods is one of the other factors affecting demand.
a. Related goods are classified as either substitutes or complements.
1. Substitutes are goods that satisfy a similar need or desire.
a. An increase in the price of a good will increase demand for its substitute, while a decrease in the price of a good will decrease demand for its substitute.
2. Complements are goods that are used jointly.
a. An increase in the price of a good will decrease demand for its complement while a decrease in the price of a good will increase demand for its complement.
3. Income is another factor that can affect demand.
a. If a good is a normal good, increases in income will result in an increase in demand while decreases in income will decrease demand.
b. If a good is an inferior good, increases in income will result in a decreasein demand while decreases in income will increase demand.
C. Other Supply Factors
1. Changes in other supply factors will result in a change in supply.
a. An increase in supply is depicted as a rightward shift of the supply curve.
b. An increase in supply means that producers plan to sell more of the good at each possible price.
c. A decrease in supply is depicted as a leftward shift of the supply curve.
d. A decrease in supply means that producers plan to sell less of the good at each possible price.
2. Other factors affecting supply include technology, the prices of inputs, and the prices of alternative goods that could be produced.
a. An advance in technology, a decrease in the prices of inputs, or a decrease in the prices of alternative goods that could be produced will result in an increase in supply.
b. A deterioration of technology, an increase in the prices of inputs, or an increase in the prices of alternative goods that could be produced will result in a decrease in supply.

When the price of a complementary products for the demand for the other product will?

The prices of complementary or substitute goods also shift the demand curve. When the price of a good that complements a good decreases, then the quantity demanded of one increases and the demand for the other increases.

What happens to demand when the price of a complementary good increases?

The demand for a good decreases, if the price of one of its complements rises. The demand for a normal good increases if income increases.

What happens to the price of complements?

If two goods are complements, this means that a rise in the price of one commodity will induce a downward shift in demand for the other commodity. The prices of complementary or substitute goods also shift the demand curve.

When two goods are complementary goods as the price of one of the goods goes?

Complementary Goods As the price for one item increases, an item closely associated with that item and necessary for its consumption decreases because the demand for the main good has also dropped.
