are so many buyers and so many sellers that each has a negligible impact on the price of the product.

In principle, we can

confirm or refute positive statements by examining evidence.

The most obvious benefit of specialization and trade is that they allow us to

consume more goods than we otherwise would be able to consume.

The term "productivity"

refers to the quantity of goods and services produced from each unit of labor input.

The phenomenon of scarcity stems from the fact that

resources are limited.

Holding the non-price determinants of supply constant, a change in price would

result in a movement along a stationary supply curve.

An increase in quantity demanded

results in a movement downward and to the right along a demand curve.

Resources are

scarce for households but scarce for economics.

The two basic reasons why economists often appear to give conflicting advice to policymakers are differences in

scientific judgments and values.

When quantity demanded increases at every possible price, the demand curve has

shifted to the right.

Efficiency means that

society is getting the maximum benefits from its scarce resources.

Given the market for illegal drugs, when the government is successful in reducing the flow of drugs into the United States,

supply decreases, demand is unaffected, and price increases.

When a supply curve is relatively flat,

supply is relatively elastic.

If the quantity supplied responds only slightly to changes in price, then

supply is said to be inelastic.

A rational decision maker

takes an action only if the marginal benefit of that action exceeds the marginal cost of that action.

Hours Needed to Make 1--Amount Produced in 60 Hours -------Mixer--Toaster-------------Mixer--Toaster Maya---6--------3------------------10-------20 Miguel-10--------5------------------6--------12 We could use the information in the table to draw a production possibilities frontier for Maya and a second production possibilities frontier for Miguel. If we were to do this, measuring toasters along the horizontal axis, then

the slope of Maya's production possibilities frontier would be -0.5 and the slope of Miguel's production possibilities frontier would be -0.5.

A university's football stadium is always sold out, and students who wait in line for hours may be turned away. This indicates

the ticket price is below the equilibrium price

Suppose there are only two people in the world. Each person's production possibilities frontier also represents his or her consumption possibilities when

they choose not to trade with one another.

If the supply of a product increases, then we would expect equilibrium price

to decrease and equilibrium quantity to increase

The balance between efficiency and equality is an illustration of

trade-offs.
