This paper revisits two conventional beliefs of environmental nonmarket valuation and examines their weaknesses and a new opportunity. The two beliefs are that willingness to pay (WTP) is an appropriate measure of non-market behaviour and that exogenous variables are relevant predictors of WTP...

Inclining block tariffs, where the unit price is dependent on the volume consumed, are widely used in urban water pricing. These tariffs attempt to satisfy both efficiency and equity goals by providing pricing signals to influence consumption decisions at the margin, whilst making...
