Abstract
The proliferation of the number of water multipliers in recent years has
increased the likelihood that misunderstanding and misuse will occur by
practitioners not well trained in the interindustry analysis. What is
needed is a more standardized terminology and a more critical evaluation of
the meaning and use of these multipliers. To this purpose, water resource
multipliers were estimated for Oahu, and the usefulness of such multipliers
for public planning and decision making in Hawaii are critiqued. The method
of analysis used is the Leontief input-output or interindustry model. The
Oahu model was developed from data used to construct the state input-output
(I-0) model. Water use by economic sector was estimated from primary and
secondary data. Three general types of water multipliers were estimated and
evaluated for Oahu. The water-final demand coefficients can be useful in
estimating water use under alternative development scenarios. The water-own
multiplier was found to have limited value for planning in Hawaii. The
water-income ratio is supposed to quantify the tradeoff between sectoral
income and water use. However, this ratio is conceptually troublesome and
it takes multiplier analysis beyond its traditional positive role into the
normative arena.
