| dc.description.abstract | Non-market valuation techniques are commonly used by economists to assess
environmental goods which are characteristically intended for public. Public
goods,here are defined as non-excludable and non-rival in consumption
(Ward and Beal 2000: 50); and they exist in many segments of society. Public
goods are usually provided for free or at minimal cost so that the model of
market demand cannot be used to estimate their value. Cultural heritage items
typically have characteristics of public goods, and therefore to assess them
requires non-market valuation techniques. Generally, there are two categories
of non-market valuation methodology used by environmental economists: the
stated preference and the revealed preference techniques. | en_US |
