Answer:
A. 90
Explanation:
nominal GDP = 50*20 + 100*8 = 1800
real GDP = 50*10 + 100*15 = 2000
GDP deflator = (nominal GDP/ real GDP)*100 = (1800/2000)*100 = 90
Answer:
3400, Rise, C
Explanation:
1. Since there are just 3 firms and two already has a sum total of 70% (40+30), the third firm will have a market share of 30%
HHI=
HHI= 1600+900+900
HHI= 3400
2. Abe's Bikes with 30% leaves the market, if the two firms were to share Abe's market share equally (15+15), it will leave Firm A with 55% (40+15) and Firm B with (30+15) 45%
Therefore,
HHI= 
HHI=3025+2025
HHI= 5050
A rise in HHI
3. C
An index of 10,000 corresponds to a monopoly firm with 100% market share.
Answer:
4%
Explanation:
If the real gross domestic product for the year grew by 2%
The inflation rate also grew by 2%
Then nominal GDP rate can be calculated as follows
= Real GDP + inflation rate
= 2% + 2%
= 4%
Hence the nominal gross domestic product grew by 4%
