Consider a world with two points in time t0, t1. Nelly Brown has just inherited $5M. She has only two projects she can invest in. Project A costs $3M at t0 and pays off $3.8M at t1. Project B costs $2M at t0 and pays off $2.5M at t1. She can lend and borrow at a bank at an interest rate of 20 percent. Nelly is only interested in consumption today at t0; she does not get any utility from consumption at t1.
a)What is the most Nelly can consume at t0? How does she achieve this(ie. what projects does she do and how much does she borrow or lend at the bank)?
b)How would your answers to a) be changed if Nelly could lend to the bank at a rate of 15 percent but could borrow at 30 percent?
