The economics literature has recently turned its attention to the existence of gender differences in various aspects
of choice behaviour. This paper focuses upon such differences as may exist in the valuation of environmental resources.
Firstly, the paper presents several reasons why women are expected to have a lower willingness-to-pay (WTP) for
environmental improvements than do men. Secondly, in order to establish the empirical extent of gender differences the
paper presents a model for estimating individual-specific benefits from environmental improvements. CVM referenda data
from are collected and used in a double-bounded probit model to estimate female versus male WTP for remedial actions
designed to improve three different water-based recreational activities in a previously highly polluted area. For these data,
the paper finds that, even after controlling for income differences, women consistently have lower WTP values. The
findings in this paper have potentially important consequences for the subsequent calculation of aggregate benefits from
contingent valuation models that ignore the role of gender. Since women generally constitute about one half of a population
base, turning a blind eye to gender means that aggregate WTP values will overstate the extent of benefits from
