Answer:
b. an outward shift of the production possibilities curve along both axes
Step-by-step explanation:
As we know that outward shift refers to the growth.
Baby boomers is a term used for the human generation born between 1946 and 1964 after the end of world war 2 when the birth rate across the world was narrowed and thereafter the emerging births of new infants were known as Baby Boom.
The main reasons of this outward shift were:
- People started new families to cover the life gap of the loved ones they lost during the world war
- People hoped that coming era will be of peace and business growth which they actually saw thereafter
- People hoped to see the economic growth in upcoming years leading them towards business expansions and production growths as well
