50 Known Thresholds In the limit ρ ±1 (complete market), the closed form expression for the investment threshold obtained in the case T = gives V DP = 2. This should be contrasted with the NPV criterion (that is, invest whenever the net present value for the project is positive) which in this case gives V NPV = 1.

This should be contrasted with the NPV criterion (that is, invest whenever the net present value for the project is positive) which in this case gives V NPV = 1. The limit γ 0 in our model corresponds to the McDonald and Siegel (1986) threshold, obtained by assuming that investors are averse to market risk but neutral towards idiosyncratic risk.

Outcomes of a given game that involve a wait and see strategy should be calculated by option value arguments. 2. Once the solution for a given game is found on a decision node, its value becomes the pay-off for an option at that node. In this way, option valuation and game theoretical equilibrium become dynamically related in a decision tree.

65 One period expansion option under monopoly Suppose now that a firm faces the decision to expand capacity for a product with uncertain demand: { hy0 with probability p Y 1 = ly 0 with probability 1 p, (5) correlated with a traded asset The expansion requires a sunk cost I. The state of the firm after the investment decision at time t k is { 1 if the firm invests at time tk x(k) = (6) 0 if the does not invest at time t k The cash flow per unit demand for the firm is denoted by D x(k).
66 The NPV solution If no expansion occurs at time t 0, then the value of the project at time t 0 is v out = D 0 Y 0 + g(d 0 hy 0, D 0 ly 0 ) = D 0 Y 0 + π 0 (D 0 Y 1 ).
67 The NPV solution If no expansion occurs at time t 0, then the value of the project at time t 0 is v out = D 0 Y 0 + g(d 0 hy 0, D 0 ly 0 ) = D 0 Y 0 + π 0 (D 0 Y 1 ). If expansion occurs, then the value of the project at time t 0 is v in = (D 1 Y 0 I ) + g(d 1 hy 0, D 1 ly 0 ) = D 1 Y 0 + π 0 (D 1 Y 1 ).
68 The NPV solution If no expansion occurs at time t 0, then the value of the project at time t 0 is v out = D 0 Y 0 + g(d 0 hy 0, D 0 ly 0 ) = D 0 Y 0 + π 0 (D 0 Y 1 ). If expansion occurs, then the value of the project at time t 0 is v in = (D 1 Y 0 I ) + g(d 1 hy 0, D 1 ly 0 ) = D 1 Y 0 + π 0 (D 1 Y 1 ). textcolorredif the decision needs to be taken at time t 0, then according to NPV the firm should expand provided v in v out, that is, if the sunk cost I is smaller then I NPV = (D 1 D 0 )Y 0 + (π 0 (D 1 Y 1 ) π 0 (D 0 Y 1 )).

69 The RO solution By contrast, if the decision to invest can be postponed until time t 1, then the value of the project when no investment occurs at time t 0 is v wait = D 0 Y 0 + π 0 (C 1 ), where C 1 denotes the random variable C 1 = C 1 (Y 1 ) = max{d 0 Y 1, D 1 Y 1 I } D 0 Y 1.
70 The RO solution By contrast, if the decision to invest can be postponed until time t 1, then the value of the project when no investment occurs at time t 0 is v wait = D 0 Y 0 + π 0 (C 1 ), where C 1 denotes the random variable C 1 = C 1 (Y 1 ) = max{d 0 Y 1, D 1 Y 1 I } D 0 Y 1. Accordingly, the firm should invest at time t 0 provided v in v wait, that is, if the sunk cost is smaller than I RO = (D 1 D 0 )Y 0 + (π 0 (D 1 Y 1 ) π 0 (C 1 )). (8)
71 The RO solution By contrast, if the decision to invest can be postponed until time t 1, then the value of the project when no investment occurs at time t 0 is v wait = D 0 Y 0 + π 0 (C 1 ), where C 1 denotes the random variable C 1 = C 1 (Y 1 ) = max{d 0 Y 1, D 1 Y 1 I } D 0 Y 1. Accordingly, the firm should invest at time t 0 provided v in v wait, that is, if the sunk cost is smaller than I RO = (D 1 D 0 )Y 0 + (π 0 (D 1 Y 1 ) π 0 (C 1 )). (8) Since the function g is non-decreasing in each of its arguments, I NPV I RO = π 0 (C 1 ) π 0 (D 0 Y 1 ) 0. (9)

Accordingly, the firm should invest at time t 0 provided v in v wait, that is, if the sunk cost is smaller than I RO = (D 1 D 0 )Y 0 + (π 0 (D 1 Y 1 ) π 0 (C 1 )). (8) Since the function g is non-decreasing in each of its arguments, I NPV I RO = π 0 (C 1 ) π 0 (D 0 Y 1 ) 0. (9) That is, according to RO, the firm is less likely to expand at time t 0.

77 Equilibrium strategies Lemma Under FMA: 1. If I < IF h, then the equilibrium strategy is (1, 1) for high and low demand. 2. If IF l < I < I F h and I < I L l, then the equilibrium strategy is (1, 1) for high demand and (1, 0) for low demand. 3. If IF h < I < I L l, then the equilibrium strategy is (1, 0) for high and low demand. 4. If IF l < I < I F h and I L l < I, then the equilibrium strategy is (1, 1) for high demand and (0, 0) for low demand. 5. If IL l < I < I L h and I F h < I, then the equilibrium strategy is (1, 0) for high demand and (0, 0) for low demand. 6. If I > I h F, then the equilibrium strategy is (0, 0) for high and low demand.

Denote by v (x i (t m),x j (t m)) i (t m, y) the continuation values: v (1,1) (1,1) g(v i (t m+1, y u ), (V (1,1) i (t m+1, y d )) i (t m, y) = D 11 y t + e r t v (1,0) (1,0) g(v L (t m+1, y u ), (V (1,0) L (t m+1, y d )) L (t m, y) = D 10 y t + e r t v (0,1) (0,1) g(v L (t m+1, y u ), (V (0,1) L (t m+1, y d )) L (t m, y) = D 01 y t + e r t v (1,0) (1,0) g(v F (t m+1, y u ), (V (1,0) F (t m+1, y d )) F (t m, y) = D 01 y t + e r t v (0,1) (0,1) g(v F (t m+1, y u ), (V (0,1) F (t m+1, y d )) F (t m, y) = D 10 y t + e r t v (0,0) (0,0) g(v i (t m+1, y u ), (V (0,0) i (t m+1, y d )) i (t m, y) = D 00 y t + e r t
85 Derivation of project values (2) For fully invested firms, the project values are simply given by V (1,1) i (t m, y) = v (1,1) i (t m, y).
86 Derivation of project values (2) For fully invested firms, the project values are simply given by V (1,1) i (t m, y) = v (1,1) i (t m, y). Now consider the project value for firm F when L has already invested and F hasn t: V (1,0) F (t m, y) = max{v (1,1) F (t m, y) I, v (1,0) F (t m, y)}.
87 Derivation of project values (2) For fully invested firms, the project values are simply given by V (1,1) i (t m, y) = v (1,1) i (t m, y). Now consider the project value for firm F when L has already invested and F hasn t: V (1,0) F (t m, y) = max{v (1,1) F (t m, y) I, v (1,0) F (t m, y)}. Similarly, the project value for L when F has invested and L hasn t is V (0,1) L (t m, y) = max{v (1,1) L (t m, y) I, v (0,1) L (t m, y)}.
88 Derivation of project values (3) Next consider the project value for L when it has already invest and F hasn t: { V (1,0) v (1,1) L (t m, y) = L (t m, y) if v (1,1) F (t m, y) I > v (1,0) F (t m, y), (t m, y) otherwise. v (1,0) L
