Answer:
increase of VAT is bad
Explanation:
In particular, raising VAT will have a negative effect on productivity growth. Increasing its rate reduces the economic incentives to trade and therefore hampers the division of labour and the associated productivity gains from increased specialisation, economies of scale and so on.
Answer:
Explanation:
a)We find the portfolio weights first. For a two security portfolio


x2 = 0.625 and x1 = 0.375
Then
rp = x1r1 + x2r2
rp = (0.375 ´ 0.06) + (0.625 ´ 0.14)
= 0.11
= 11.0%
Hence, he can improve the expected rate of return without any change in the risk of the portfolio.
b)
The expected return is:
rp = x1r1 + x2r2
rp = (0.5 *´ 0.09) + (0.5 ´* 0.14)
= 0.115 = 11.5%

sP2 = (0.5)^2(0.10)^2 + 2*(0.5)(0.5)(0.10)(0.16)(0.10) + (0.5)^2(0.16)^2
sP2 = 0.0097
sP = 0.985 = 9.85%
Hence, he can never perform better by investing equal amount in bond portfolio and index fund. The expected return increases to 11.5% and standard deviation decreases to 9.85%.
