The paper offers an innovative approach to valuation of biodiversity. Instead of the prevailing approach of using only one indicator of biodiversity (usually number of species) we provide evidence that it is possible to provide attributes describing complex characteristics of biodiversity based...

Insufficient sensitivity to scope remains one of the pivots of criticism addressed at validity of stated preference methods. Many studies demonstrate failure of a scope test of some sort, while many others show that WTP responses are sensitive to the scope of environmental change. Despite some...

Using multiple choice tasks per respondent in discrete choice experiment studies increases the amount of available information. However, respondents’ learning and fatigue may lead to changes in observed utility function preference (taste) parameters, as well as the variance in its error term...

The estimates of mean WTP are typically of main interest in non-market valuation studies. In the case of mixed logit models the distribution of WTP for an attribute is derived from the distribution of the ratio of individual coefficients. Since the cost coefficient enters the denominator, its...

The paper aims at investigating the validity of benefit transfer in the case of transfers between countries highly heterogeneous in income, and demonstrates relative performance of different benefit transfer methods under these conditions. Lake water quality valuation studies were conducted in...

There are two major ways in which solid waste can be sorted and recycled - at the household level, when households are required to sort waste into a given number of categories, or in specialized sorting facilities. Traditionally, it has been thought that sorting at the household level is an...

We estimate and compare two empirical measures of the weak sustainability of an economy for the first time: the change in augmented green net national product (GNNP), and the interest on augmented genuine savings (GS). Yearly calculations are given for each measure for Scotland during 1992-99....
