Comparative Statics of SVRRs and VSL with respect to Income and Survival Probability.

	Income: Single-period difference	Income: permanent difference	Survival probability: single-period difference	Survival probability: permanent difference
Utilitarian SVRR	Past period: Unchanged Current period: Increasing Future period: Increasing	Increasing	Current period: Unchanged Future period: Increasing	Increasing
Ex Ante Prioritarian SVRR	Past period: Decreasing Current period: Ambiguous* Future period: Ambiguous*	Ambiguous	Current period: Decreasing Future period: Ambiguous*	Ambiguous
Ex Post Prioritarian SVRR	Past period: Decreasing Current period: Increasing Future period: Increasing	Ambiguous	Current period: Unchanged Future period: Increasing	Increasing
VSL	Past period: Unchanged Current period: Increasing Future period: Increasing	Increasing	Current period: Decreasing Future period: Increasing	Ambiguous

^*The ex ante prioritarian SVRR increases with a single-period increment to current or future income, and increases with a single-period increment to future survival probability, if g(·) is such that its coefficient of relative risk aversion is always less than or equal to 1.
