below:
(1 — δι)[1 — δ1δ2 + αιλι(1 + δι)(1 — δ2)]
(1 - διδ2)
(24)
Then the equilibrium payoffs are as follows:
u1
1 — δ1δ2 + α1δ1λ1(1 — δ1δ2)
1 — δ1δ2
u2
α2(1 — δι)
1 — δ1δ2
(25)
(26)
2) If o ≤ α1 ≤ q, the equilibrium demands are defined in (27) and (28) below
x1
y2
(1 — δ2)[(1 — διδ2)λι + (1 — δ1)(α2λ1λ2(1 + δ2) — δ2αι(1 + δι))]
λ1(1 — δ1δ2)2
(1 — δ1)[(1 — δ1δ2)λ1 + (1 — δ2)(α1(1 + δ1) — α2λ1λ2δ1(1 + δ2))]
λ1(1 — δ1δ2)2
(27)
(28)
and the equilibrium payoffs are as follows:
u1
u2
1 — δ2
λ2(1 — δ1δ2)2
[(λ2 + α2)(1 — δ1δ2) + (α2 — α1λ1λ2)(δ2
— δ1)]
δ2(1 — δ1)
(1 — δ1δ2)2
[λ2(1 + α1λ1)(1 — δ1δ2) + (α2 — α1λ1λ2)(δ2
— δ1)]
(29)
(30)
3) If q ≤ α1 ≤ 1, the equilibrium demands are y2 =1 and x1 = xe1 ∈ (0, 1), where
(1 — δ2)[(1 — δ1δ2)λ2 + α2(1 — δ1)(1 + δ2)]
(1 — δ1δ2)λ2
(31)
and the equilibrium payoffs are as follows:
u1
u2
(1 — δ2)[λ2(1 — δ1δ2) + α2(1 + δ2)(1 — δ1) + α1δ1λ1λ2]
λ2(1 — δ1δ2)
δ2[λ2(1 — δ1δ2) + α2δ2(1 — δ1)]
1 — δ1δ2
