Factors of production are
inputs into the production process
Factors of production are:
inputs into the production process.
Another term for factors of production is:
inputs

$150
If the price elasticity of demand for a good is 1.2, then a 3 percent decrease in price results in a:
3.6 percent increase in the quantity demanded
If consumers view cappuccinos and lattés as substitutes, what would happen to the equilibrium price and quantity of lattés if the price of cappuccinos falls?
Both the equilibrium price and quantity would decrease.
What will happen in the gasoline market now if buyers expect higher gasoline prices in the near future?
The demand for gasoline will increase.
Which of the following demonstrates the law of supply?
When ketchup prices rose, ketchup sellers increased their quantity supplied of ketchup
Using the midpoint method, the price elasticity of demand for a good is computed to be approximately 0.75. Which of the following events is consistent with a 10 percent decrease in the quantity of the good demanded?
a 13.33 percent increase in the price of the good
If the price elasticity of demand for a good is 0.8, then a 12 percent increase in the quantity demanded must be the result of:
a 15 percent decrease in the price.
Which of the following changes would not shift the demand curve for a good or service?
a change in the price of the good or service
When demand is elastic, an increase in price will cause
a decrease in total revenue
Market failure is the inability of:
a market to allocate resources efficiently
If a shortage exists in a market, then we know that the actual price is:
below the equilibrium price, and quantity demanded is greater than quantity supplied.
Total surplus is represented by the area:
between the demand and supply curves up to the point of equilibrium
Suppose that the market price for pizzas increases. The increase in producer surplus comes from the benefit of the higher prices to
both existing sellers who now receive higher prices on the pizzas they were already selling and new sellers who enter the market because of the higher prices
In economics, capital refers to:
buildings and machines used in the production process
Demand is said to be price elastic if:
buyers respond substantially to changes in the price of the good
The line that relates the price of a good and the quantity supplied of that good is called the supply:
curve, and it usually slopes upward
You have been asked by your economics professor to graph the market for lumber and then to analyze the change that would occur in equilibrium price as a result of recent forest fires in the west. Your first step would be to
decide whether the fires affected demand or supply
A movement downward and to the left along a supply curve is called a(n):
decrease in quantity supplied
A movement downward and to the left along a supply curve is called a(n)
decrease in quantity supplied.
A movement downward and to the left along a supply curve is called a(n):
decrease in quantity supplied.
what events must cause equilibrium quantity to rise?
demand and supply both increase
A typical society strives to get the most it can from its scarce resources. At the same time, the society attempts to distribute the benefits of those resources to the members of the society in a fair manner. In other words, the society faces a tradeoff between:
efficiently and equality
A likely effect of government policies that redistribute income and wealth from the wealthy to the poor is that those policies
enhance equality
Suppose the cross-price elasticity of demand between peanut butter and jelly is -2.50. This implies that a 20 percent increase in the price of peanut butter will cause the quantity of jelly purchased to:
fall by 50%
If an increase in income results in a decrease in the quantity demanded of a good, then for that good, the:
income elasticity of demand is negative
In a market economy, economic activity is guided by:
individuals acting in self-interest
The principle that "people face tradeoffs" applies to:
individuals, families, and societies
Assume that a 4 percent increase in income results in a 2 percent increase in the quantity demanded of a good. The income elasticity of demand for the good is:
positive, and the good is a normal good.
As we move downward and to the right along a linear, downward-sloping demand curve:
slope remains constant but elasticity changes
As we move downward and to the right along a linear, downward-sloping demand curve,
slope remains constant but elasticity changes.
As we move downward and to the right along a linear, downward-sloping demand curve:
slope remains constant but elasticity changes.
A microeconomist — as opposed to a macroeconomist — might study
the effect of new regulations on production in the pulp and paper industry.
