Calculating the yield on the bond of the short-term nominal risk-free interest rate
Nominal risk-free interest rate + Default Premium + Liquidity premium + Maturity Premium
Equation to use to cal. how long for investment account to double
FVn = PV[1+(rs/ln)]mN
Calculating trade deficit using GDP Data of a country
S = I + (G – T) + (X – M), where
S = Domestic savings
I = Private investment
G = Government spending
T = Total government tax revenues
X = Exports
M = Imports
G – T = The government deficit
X – M = The trade deficit
The trade deficit will be (X – M) = (S – I) – (G – T).
Equation for future value
FV=PV(1+rsm)mN
What is EAR and how it is calculated?
The effective annual rate (EAR) when compounded daily
EAR = (1 + Periodic interest rate)m– 1
An investment pays €300 annually for five years, with the first payment occurring today. The present value (PV) of the investment discounted at a 4% annual rate is closest to:
€1,336.
€1,389.
€1,625.
B is correct, as shown in the following calculation for an annuity (A) due:
PV=A⎡⎣⎢⎢⎢⎢1−1(1+r)Nr⎤⎦⎥⎥⎥⎥(1+r)
where A = €300, r = 0.04, and N = 5.
PV=€300⎡⎣⎢⎢⎢⎢1−1(1+.04)5.04⎤⎦⎥⎥⎥⎥(1.04)
PV = €1,388.97, or ≈ €1,389.
