  This paper presents an analysis of the stochastic recursion $W_{i+1} =
[V_iW_i+Y_i]^+$ that can be interpreted as an autoregressive process of order
1, reflected at 0. We start our exposition by a discussion of the model's
stability condition. Writing $Y_i=B_i-A_i$, for independent sequences of
non-negative i.i.d.\ random variables $\{A_i\}_{i\in N_0}$ and $\{B_i\}_{i\in
N_0}$, and assuming $\{V_i\}_{i\in N_0}$ is an i.i.d. sequence as well
(independent of $\{A_i\}_{i\in N_0}$ and $\{B_i\}_{i\in N_0}$), we then
consider three special cases: (i) $V_i$ attains negative values only and $B_i$
has a rational LST, (ii) $V_i$ equals a positive value $a$ with certain
probability $p\in (0,1)$ and is negative otherwise, and both $A_i$ and $B_i$
have a rational LST, (iii) $V_i$ is uniformly distributed on $[0,1]$, and $A_i$
is exponentially distributed. In all three cases we derive transient and
stationary results, where the transient results are in terms of the transform
at a geometrically distributed epoch.
