Unformatted text preview: where every variable in the right hand side is exogenous variable. The comparative statistic results will be as ∆r = (1/d)∆a ∆r = (1/d)∆c ∆r = (1/d)∆G ∆r = (b/d)∆T Based on these, you should be able to answer problems 8 and 10 verbally, mathematically and graphically. Another way to see this is to take total differentiation of Y – a – b(Y – T) – G = cdr And obtain ∆Y  ∆a – b(∆Y  ∆T)  ∆G = ∆c  r∆d  d∆r To find the effect of a change in T, i.e., ∆T > 0, we set ∆Y = 0, ∆a = 0, ∆G = 0, ∆c = 0, and have b(∆T) =  d∆r → ∆r = (b/d)∆T. Apply the same approach, we can obtain ∆r = (1/d)∆a; ∆r = (1/d)∆c; ∆r = (1/d)∆G...
