Organization size and the optimal investment in cash
journal contribution
posted on 2012-07-30, 09:15 authored by Andrew Higson, Yoshikatsu Shinozawa, Mark TippettMiller & Orr (1966, Q. J. Econ., 80, 413–435) formulate a cash management model under which an
organization’s cash flow evolves in terms of a stationary random walk. This, in turn, implies that the organization’s
demand for cash will not grow over time. However, as organizations grow one would expect
the demand for cash to grow as well. Given this, we formulate a cash management model under which
movements in an organization’s cash balance hinge on its current rate of output or an equivalent size measure.
Cash is withdrawn and invested in interest-bearing securities when the cash to output ratio becomes
too high, while securities are sold and the proceeds deposited in a non-interest-bearing bank account
when the cash to output ratio becomes too low. The control limits are determined so as to minimize the
expected annual cost of a unit of output. Our analysis shows that when organization’s cash flows follow a
non-stationary process, the optimal cash management policies are profoundly different to those obtained
under the Miller & Orr (1966) model.
