Contract Strategies in Competing Supply Chains with Risk-Averse Suppliers

Table 1

Stability analysis of risk-neutral suppliers’ perspectives.

Original structure	M1		M2
	New structure	Change in profits	New structure	Change in profits
WW	RW	0<𝜃<1, ↑*	WR	0<𝜃≤0.55, ↑
				0.55<𝜃<1, ↓
RW	WW	0<𝜃<1, ↓	RR	0<𝜃≤0.51, ↑
				0.51<𝜃<1, ↓
WR	RR	0<𝜃≤0.69, ↑	WW	0<𝜃≤0.55, ↓
		0.69<𝜃<1, ↓		0.55<𝜃<1, ↑
RR	WR	0<𝜃≤0.69, ↓	RW	0<𝜃≤0.51, ↓

∗When the utility of new structure is more than the original structure, we denote it by “↑”, otherwise, “↓”.
