When formulating a plan for savings, does the timing of income risks matter
? Should one be concerned with whether uncertainty in income is in the near
term, or the distant future? Of course, and the impact of the timing of in
come risk is the subject of this article. Using a three-period framework, w
e provide approximate solutions for optimal consumption choices for prefere
nces that display constant relative risk aversion and derive the relationsh
ip between innovations to income and innovations to consumption growth. The
se results are contrasted with those for quadratic preferences and preferen
ces that display constant absolute risk aversion. We analyze consumption-sa
ving plans for several different situations of near term and distant future
income risk, and different kinds of preferences. We conclude with a demons
tration of the high degree of accuracy of our consumption approximations by
comparing them to exact values computed by stochastic simulation. (C) 1999
