9. Consider the foreign exchange model ds=(r-Q)sdt+sigma sdw(t), what does r
and Q stands for? Consider u=1/s, calculate du.explain the paradox(Change
of numeria, shreve book has a very nice explainition)
这个Q到底是什么?
19 A zero coupon bond, pays $100 face value, current $95, a contract pays $1
when the bond hits $98, price the contract.
答案是95/98吗?
20.explain forward rate agreement? Under forward measure, it is a martingale
? what about Risk neutral measure.
FRA当然清楚,但是它由两项组成,能是MG吗?

could be like the way to price digital option. Use the interest rate model
like CIR (not sure?) and find the probability that the bond hits $98 or more.

$1
martingale
