Inelastic
Raising prices raises revenue
A firm estimates that the absolute value of the price elasticity of demand for its signature sandwich is 2. If the firm increases its sandwich price by 10%, what will happen to the quantity demanded

Suppose the small country of Aronow imports 40,000 kg of bananas. The global price of bananas is $.50 and they collect $4,000 in tariff revenues from banana imports what statement is true
The consumer pays $0.60 per kg of bananas
The market for tomatoes is in the equilibrium at the price of $10 for 50 tomatoes. If the consumer surplus is $400 and the total surplus is $650, what is the surplus in the tomato market and why
The producer surplus is $250; because the total surplus less what consumers receive must go to producers
Which of the following will occur as a result of a decrease in the prices of the inputs used to produce a good
The quantity supplied would increase at each possible price for the good
Assume that the market for a good is characterized by a downward sloping demand curve and upward sloping supply curve. Suppose there was an improvement in technology for producing the good, which of the following would occur
The total surplus in the market would increase
Which of the following will initially result from an increase in the market demand for a good
There will be a temporary shortage at the original equilibrium price
Suppose supply for oranges intersects demand where the price elasticity of demand for oranges is -1.8. If a frost destroys one third of the nations orange crop how will it affect total revenue from oranges, all other things unchanged
Total revenue will fall because the decrease in quantity is large relative to increase in price
Supplier Surplus
Value of the difference between the marginal cost and marginal benefit
A newspaper typically consumes a smaller fraction of a consumer's budget than a home entertainment system. Therefore, you would expect the demand for:
a home entertainment system to be more price-elastic.
price elasticity of demand
a measure of how much the quantity demanded of a good responds to a change in the price of that good, computed as the percentage change in quantity demanded divided by the percentage change in price
price elasticity of supply
a measure of how much the quantity supplied of a good responds to a change in the price of that good, computed as the percentage change in quantity supplied divided by the percentage change in price
Sometimes airlines raise ticket prices as the flight departure date approaches in the hope of increasing revenue. The airlines raise their prices on the assumption that:
consumer demand becomes less price-elastic as departure time approaches

deadweight loss
the fall in total surplus that results from a market distortion, such as a tax
