an increase in the price of an alternative product that could be produced with the same resources.

A shortage is represented by the distance:

between the demand curve and the supply curve below the equilibrium point. The distance between the demand curve and the supply curve below the equilibrium point represents a shortage (where quantity demanded is greater than quantity supplied).

When the price of a good changes in a market:

both quantity demanded and quantity supplied for the good change. Consumers and producers both react to price changes.

Price elasticity of demand measures how:

consumers respond to a change in price. Price elasticity of demand measures the change in quantity demanded caused by a change in the product's price.

Whether two goods are substitutes or complements can be determined by computing the:

cross elasticity of demand. Cross elasticity of demand is used to determine if goods are substitutes or complements.

Price elasticity of demand is a measure of how responsive a change in quantity demanded is to a change in:

price Price elasticity of demand measures how responsive a change in quantity demanded is to a change in the price of a product.

The ratio of the percentage change in quantity demanded to the percentage change in price is called:

price elasticity of demand Price elasticity of demand measures how responsive a change in quantity demanded is to a change in price.

Ceteris paribus, the effect of a decrease in income on a normal good is to shift the:

demand curve to the left, reducing both equilibrium price and output. A decrease in income will decrease demand for a normal good and decrease its price and quantity.

If the price elasticity of demand for corn dogs is 1.8, then the price elasticity for corn dogs is considered:

elastic. If price elasticity is greater than 1, then price elasticity of demand is elastic.

If the price elasticity of demand for ice cream is 1.6, then the price elasticity for ice cream is considered:

elastic. If price elasticity is greater than 1, then price elasticity of demand is elastic.

If farmers begin using better fertilizers to grow corn, we would expect a(n) __________ in the supply of corn.

increase An improvement in technology would make it easier to grow corn, thereby increasing its supply.

Ceteris paribus, a decrease in the number of businesses selling pizza will cause a(n):

increase in the equilibrium price of pizza. A decrease in the number of producers will decrease supply and increase price.

According to the following figure, an increase in demand will:

increase price only. Since the supply curve is vertical in this case, an increase in demand will only increase price.

Assuming everything else stays the same, an increase in the price of smartphones will __________ of smartphones.

increase the quantity supplied According to the law of supply, an increase in the price of a good will increase the quantity supplied of that good.

If the price elasticity of demand for facial tissue is 0.4, then the price elasticity for facial tissue is considered:

inelastic. If price elasticity is less than 1, then price elasticity of demand is inelastic.

According to the law of demand, the price of coffee and the quantity of coffee demanded are:

negatively related.

If a competitive market is NOT at equilibrium:

the price will change and in response, market participants will move along the existing supply and demand curves until the market reaches equilibrium. In a competitive market, the price will increase if the current price is below equilibrium. If the current price is above equilibrium, it will decrease.

Over time, LCD TV production costs have fallen. Also, more people around the globe have enough money to buy LCD TVs due to increases in income from economic growth. The net result of these two forces has been more LCD TVs sold for lower prices. This is an example of:

the supply and demand curves shifting to the right, with supply shifting more than demand. Supply shifts to the right due to lower production costs while demand shifts to the right due to higher consumer income. We know that supply must have shifted more than demand because our new equilibrium is at a higher quantity and lower price.

In the free market, the main signal to the market that brings the price to equilibrium comes from:

the surplus or shortage of output for sale. When there is a surplus of a good, it is put on sale. When there is a shortage of a good, its price increases.
