Valuing ecosystem resilience AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
The concept of ecosystem resilience is being increasingly discussed as a driver of biodiversity values. It implies that marginal deteriorations in ecosystem conditions can abruptly result in non-marginal and irreversible changes in ecosystem functioning and the economic values that the ecosystem generates. This challenges the traditional approach to the valuation of biodiversity, which has focused on quantifying values attached to individual species or other elements of ecosystems. As yet, little is known about the value society attaches to changes in ecosystem resilience. This paper investigates this value. A discrete choice experiment is used to estimate implicit prices for attributes used to describe ecosystem resilience using the Border Ranges...

Ordering effects and strategic response in discrete choice experiments AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
This study explores ordering effects and response strategies in repeated binary discrete choice experiments (DCE). Mechanism design theory and empirical evidence suggest that repeated choice tasks per respondent introduce strategic behavior. We find evidence that the order in which choice sets are presented to respondents may provide strategic opportunities that affect choice decisions (‘strategic response’). The findings propose that the ‘strategic response’ does not follow strong cost-minimization but other strategies such as weak cost-minimization or good deal/ bad deal heuristics. Evidence further suggests that participants, as they answer more choice questions, not only make more accurate choices (‘institutional learning’) but may also become...

Effects of alternative elicitation formats in discrete choice experiments AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
An elicitation format prevalently applied in discrete choice experiments (DCEs) offers each respondent a sequence of choice tasks. Each choice task contains more than two choice options. Empirical evidence shows, however, that repeated choice tasks influence choice behaviour through institutional learning, fatigue, value learning and strategic response. The study reported in this paper uses a split sample approach. This approach was based on field surveys using a single binary elicitation format. To expand the research on effects of sequential binary DCE formats, a majority vote baseline was used. We present evidence for effects caused by institutional learning, and by either strategic behaviour or value learning, after respondents answered repeated...

Environmental value and valuation over time AgEcon
Scheufele, Gabriela; Bennett, Jeffrey W..
Time and value are related concepts that influence human behaviour. Although classical topics in human thinking throughout the ages, few environmental economic non-market valuation studies have attempted to link the two concepts. Economists have estimated non-market environmental values in monetary terms for over 30 years. This history of valuation provides an opportunity to compare value estimates and how valuation techniques have changed over time. This research aims to compare value estimates of benefits of a protected natural area. In 1978, Nadgee Nature Reserve on the far south coast of New South Wales was the focus of the first application of the contingent valuation method in Australia. This research aims to replicate that study using both the...
