Choice modelling and non-market environmental valuation in Australia have reached a crucial juncture. With significant applications, funding for research, and prominent networks of training, it's vital to reflect on past developments and explore future prospects. Initiatives like the Environmental Economics Research Hub are redefining valuation in policy-making. Despite an evolving landscape, challenges such as skepticism, context sensitivity, and the need for rigorous assurance of findings complicate progress. This work examines past experiences and anticipates future trajectories in choice modelling within environmental contexts.

Choice Modelling in Australia:past, present and future Jeff Bennett Crawford School ANU
Some quiet contemplation • Non-market environmental valuation … and choice modelling in particular … appears to have reached a turning point in Australia • Significant interest in applications and useful levels of funding for research • Some strong ‘nodes’ of application and training • Appropriate to contemplate what has happened, to assess where we are, to speculate on future developments and to plan
In the beginning … • The Phoenix of Kakadu • Resource Assessment Commission Forestry Inquiry … the appetite for CVM applications had been lost • Contingent Ranking and Rating? • Louviere and Hensher • Vanuatu Forests … CV and CM studies for ACIAR • Flatley, Rolfe • LWRRDC “General Call” application • Blamey, Morrison, Huybers, Whitten
Slow and steady • Sequence of applications and developments • National Land and Water Audit • NSW EPA • Fitzroy River Basin • SA - CSIRO • WA - UWA • Vic – Neil Sturgess … Rivers and VEAC • NZ – Kerr and Sharp • Health and transport developments
Not always forward • NSW Rivers … two steps forward and one step back • Living Murray … one step forward and one step back • Great Barrier Reef …two steps forward and into oblivion • MBIs … no interest in assessing the level of investment • MCA … advanced as the means for avoiding the need for the hassles of NMV • The politics of economic analysis
A new impetus • Inception of the Environmental Economics Research Hub • Specific interest in advancing non-market valuation as a key element of developing government policy • Hub theme devoted to Valuation • Specific projects looking at: • Integrating valuation into bio-economic models • Scope and scale effects • Time • Uncertainty • Expert vs lay values • Preparation of an application guide
Why now? • People • demand: DEWHA, State agencies • supply: capacity • Policy • Environmental issues to the fore • BUT the ‘ascendancy’ of economics and finance • Pressure • Regulatory Impact Statements
Remaining barriers • Deeply held scepticism in some quarters • The ‘anti-economics’ environmental lobby • The ‘anti-economics’ bureaucrats • The antagonistic economists • The political process … rent seeking rules • Technical issues
The research frontier • Demonstrating the accuracy of results remains the ‘holy grail’ … policy makers require the assurance that they are not entering a quagmire of dispute • Incentive compatibility … belief in the results is ‘counterintuitive’ to decision makers • Hypothetical bias … also ‘counterintuitive’ • Context sensitivity … what is the ‘right’ context? • Scope and scale … framing concerns • Questionnaire presentation issues … cognition, comprehension, confusion • Information provision
Room for wide-scale experimentation (lab and field) … especially revealed vs stated preference comparisons that are not confounded by the public/private good divergence • Consistency and convergence • Useful to find points of agreement within the profession without ‘standardisation’ • Avoid ‘freezing’ the evolutionary process
Contingent behaviour and choice modelling • ‘Green’ accounting … at the national scale and for individual environmental assets … values for stocks and flows of non-marketed assets • Coping with uncertainty • Dealing with the ‘over-surveyed’ respondent • ….
Timing is vital for policy making. Without a bank of studies and a well-recognised process of benefit transfer, the time needed to do environmental valuation (esp stated preference work) is a killer. • Benefit transfer – to be widely accepted – needs to be founded on a thorough understanding of the impacts of all the variables affecting value estimates … scope, frame, presentation etc etc
