8.Calculating the risk premium on bonds, the text presents a formula where (1+i)=(1-p)(1+i+x)+p(0) p is the probability the bond does not pay at all (the bond issuer is bankrupt) and has a zero return. i is the nominal policy interest rate, x is the risk premium. If the probability of bankruptcy is zero, what is the rate of interest on the risky bond? calculate the probability of bankruptcy when the nominal interest for a risky borrower is 8% and the nominal policy rate of interest is 3%? calculate the nominal interest for a borrower when the probability of bankruptcy is 1% and the nominal policy rate of interest is 4%? calculate the nominal interest rate for a borrower when the probability of bankruptcy is 5% and the nominal policy rate of interest is 4%? the formula assumes that payment upon default is zero. In fact it is often positive. How would you change the formula in this case?
