JNU 2012 Answer Key

[neha:)]

Hi Viv..
In Q. 91, If I am not wrong, we need to determine the tax rate that implements purchase of exactly two cows.
And according to you, when n=2, new TR-TC = 14-2t.
By putting different values of 't' from the options, I found that option (c) i.e t=0 maximizes the aggregate income, and not t=6.
Please help. I'm stuck :(

[ViV]

[bhavya jain]

someone, plz tell the approach to 76-79

[ViV]

76
Growth of Real GDP
1975-80, 21-17/17= 0.2352
1980-85, 26-21/21= 0.2380
1985-90, 32-26/26= 0.2307
1990-95,39-32/32= 0.2187
So Highest is in 1980-85.

77
Lowest is in 1990-95 refer last calculations

78
First solve Growth of Nominal GDP
1975-80, 26-21/21= 0.2380
1980-85, 32-26/26= 0.2307
1985-90, 39-32/32= 0.2187
1990-95, 47-39/39= 0.2051

GDP Deflator = (Nominal GDP/Real GDP)*100
1975-80, (0.2380/0.2352)*100 = 101.19
1980-85, (0.2307/0.2380)*100 = 96.93
1985-90, (0.2187/0.2307)*100 = 94.79
1990-95, (0.2051/0.2187)*100 = 93.78
So in 3 periods economy experienced Deflation

79
In 1 period economy experienced Inflation

If possible then plz explain Q44 and Q45

[bhavya jain]

i approached q44-45 this way-
we are given that both the statements of person in hockey team are true, in soccer team are false & in cricket team one true & another false.
first consider B; assume B is in the soccer team(means both of his statements are false). From this we know 1) B is actually in the soccer team, & 2) D is not in the cricket team.( D must be in the hockey team)
so, 44) b
now consider each of the options for 45). If A is in the cricket team, then one of his statement is true & other is false. This implies, his first statement is right & 2nd one is wrong(which we already have proved in 44)
thus, A belongs to the cricket team. So 45) a

Sir, regarding q23 and 24, I understand why the government spending multiplier (dy/dg) = 4. But how do we know 4 is also the balanced budget multiplier ?
