Scale and scope effects on communities’ values for environmental improvements in the Namoi catchment: A choice modelling approach

Abstract

This report presents results of research designed to investigate variations in willingness to pay (WTP) estimates across different scales and scopes of environmental investments. The goal is to help catchment management authorities better prioritise their natural resource management actions at both catchment and farm levels. Five split samples were used to test for scale and scope effects. A choice-modelling (CM) analysis was used to elicit household WTP for improvements in environmental quality attributes in the Namoi catchment. The approach was developed so that value estimates could be more accurately transferred between different action scopes.choice modelling, scale effect, scope effect, embedding, non-market valuation, catchment planning, environment., Community/Rural/Urban Development, Environmental Economics and Policy, Research Methods/ Statistical Methods,
