What can cause a production possibilities curve to move to the right?

an epidemic kills thousands of young men and women

thousands of people move out of the country

the population is growing increasingly old

a new invention lowers the cost of production

Thousands Of people move to a country

Explanation:

honestly its my best guess

The basic idea is that anything that causes economic output to increase or decrease will shift this curve ... When the economy grows and all other things remain constant, we can produce more, so this will cause a shift in the production possibilities curve outward, or to the right.
