In the short run,
a decrease in inflation temporarily increases unemployment.

Externalities and Market Power
can lead to market failure
In a market economy an increase in the price of a good or service reflects
either an increase in its value to society or an increase in its cost to produce.

Variations in the standard of living across countries
is due almost entirely to differences in each nation's total output of goods and services.
Trade makes costs
lower and raises the variety of goods and services available.
People respond to incentives
means people may alter their decisions when the costs and benefits of an action change.
Efficiency
refers to how much a society can produce with its resources. Equity refers to how fairly the benefits from using resources are distributed between members of society.
Trade-offs are required because wants are unlimited and resources are
scarce
Resources are
scarce for households and scarce for economies.
Resources are scarce
so a society cannot give all individuals the standard of living to which each aspires.
Economics is the study of how
society manages its scarce resources.
Because people respond to incentives, we would expect that if the average salary of accountants increases by 50 percent while the average salary of teachers increases by 20 percent,
students will shift majors from education to accounting.
