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...

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. We examine how income elasticity of WTP varies in line...

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...

This paper explores both theoretically and empirically whether or not the willingness to pay (WTP) for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions, which are...

The contingent valuation (CV) method uses respondents’ stated choices made in hypothetical situations to infer their preferences for environmental public goods. It enables the general public’s preferences to be stated in monetary terms and hence to estimate the economic value of a change in...
