Seeking macroeconomics help..

I have a few macroeconomic homework questions which I didn't quite get..

.

I found out what happens to the GDP but i'm not really sure why it happens:

a) GDP increases
b) No affect on GDP
c) GDP increases
d) No affect on GDP
e) GDP decreases since the Canadian government is paying outside of the country for a good.

I think I got the reason for e, but what are the other reasons?

I'm not really sure how to find the GDP. I'm assuming I have to add a bunch of these up. So starting from the top, if consumption expenditures is $600 do I add $600 to GDP? And add 75 from exports on top of that? I'm not sure about many of them. Would imports mean I subtract 50 from the GDP? And isn't Household purchases of durable goods fall under Consumption expenditures?

I don't really have any clue how to do this

From my book I know that:

participation rate = labour force / working-age population

However we only know participation rate so we can't find the other 2..

Also from my book:

labour force = employed workers + unemployed workers

We are given none of this info..

And lastly from my book:

unemployment rate = unemployed workers / labour force

All we are given is unemployment rate..

How would I figure the labour force, working-age population, number of employed workers, and number of unemployed workers out?

 

1.
a - money is paid from produced work, new value (goods & services) is added to economy.
b - money is given to insurance which is not really paying for new value. no new value is added to economy.
c - building airport added value to economy.
d - bond was new goods and services when it was bought. After being bought, bond is not new anymore, thus interest paid for bond does not add new value.
----> the key is newly added value or not.

2. Use the formula: GDP = Consumption + Investment + Government Spending + (Export - Import)

3. Use GDP Deflator formula: GDP Deflator = (Norminal GDP/Real GDP)*100
99.1 = (928.3*100)/Real GDP
Solve this and you get Real GDP of 936.73 for 1998

4. Participation rate is 62.5%, so non-participation rate is 37.5% (100-62.5).
"Non-participation rate" means "not in the labour force". 37.5% is 60 million, so 62.5% is 100 million. So the labour force is 100 million.

Use the formula "participation rate = labour force / working-age population", we have 62.5%=100/working-age population. Solve this and we get working-age population of 160 million.
Unemployment rate is 5%, so employment rate is 95%. 95% * 100 million (labour force) = 95 million. Number of employed workers is 95 million, number of unemployed workers is 5 million.

Hopefully I did not make any stupid mistake.
