Question 1

NPV of upgrading = $4.67M; worth upgrading. Also acceptable: PV of upgraded highway is $44.7M which exceeds the $40M PV of the existing highway. 

Question 2

(2a) EV of trial = $150M; settling is better by $100M.

(2b) EV of trial = -$410M; settling is better.

Question 3

(3i) ENPV of A = $22.8M; ENPV of B = $15M; A would be adopted.

(3ii) ENPV of the study = $69.9M; worth conducting it.

Question 4

Horizontal intercept of the BC, the PVI, is $183k.  C0 = $68.75k and she saves $31.25k.  C1 = $137.5k. Her indifference curves are right angles.

Question 5

Q=443, P=$671, profit=0.

Question 6

(6A) Q=36, P=$185, profit=$6480.

(6Bi) PV=$31,555.

(6Bii) ENPV=-$3378; firm would NOT undertake it.

(6Ci) ENPV to the firm=$835; firm would undertake it.

(6Cii) ENPV to the VC=$1691; VC would undertake it.  Both parties can benefit even though the firm alone wouldn't undertake the project because the VC can borrow at a much lower interest rate.  That increases the PV of its share of the profits relative to what those profits were worth to the firm.
