Per Capita Income growth

CFA Level II Economics
#1

In one of the EOC, the curriculum indicates that the increase in labor force participation rate increases per Capita GDP.

I can understand that the GDP increases, but doesnt labor participation also increase labor available(and thus the denominator)?

Also in the neoclassical model, only technology can bring a permanent increase in growth rate so I am not sure what model to use when answering these questions. Any advice would be helpful.

If your population is two people with only one of them earning $100,000/year, that’s $50,000/year per capita. If both of them are earning $100,000/year, that’s $100,000/year per capita.

I understand that but I guess my confusion is which people should be included in the ‘Capita’ calculation?

Should we include all people in the country or all people part of the labor force?

All those people, and only those people, who have heads.
