Cultural Amenities

The main objective of this study is to estimate the welfare values related to sustained water flows in the Zayandeh-Rud River for recreational and cultural amenities in the urban park of Isfahan City in Iran. As is elsewhere the case in arid regions, the drying up of the river due to growing water demand and the increasingly constrained water supply as a result of climate change and more frequent droughts is expected to result in a substantial welfare loss. A double-bounded discrete choice elicitation format is applied in a stated choice survey conducted among local residents and non-residential visitors, focusing on distance-decay and the relationship between income and demand for sustained water flows in publicly provided urban space under climate change. We reject the general finding in the literature that visitors living further away are willing to pay more for unique sites. We show that the recreational services provided by the park can be characterized as a normal economic good for which those living closer by are willing to pay more than those living further away. These results provide an important benchmark for future stated preference research related to welfare valuation of water in urban open space under climate change.

Clinically Significant

The purpose of this study was to determine whether an adapted stimulus elicitation format would reduce the amount of final consonant absence in African American Vernacular English (AAVE) speakers and to determine the extent to which the adapted and standard response formats would differ in their predictions of membership in a delayed and a typical group. Findings revealed that the alternate response mode resulted in statistically significant decreases in the use of final consonant absence and that it was less likely than the standard response mode to penalize the AAVE speaker to a degree that was clinically significant.

Choice Method

Objectives:To compare four contingent valuation elicitation methods as a means to estimate the value of a pneumococcal vaccine in Bangladesh and to test if the elicitation methods are subject to bias and if they produce valid responses.Methods:Three hundred sixty-one households with at least one child under 5 years of age were recruited in Dhaka, Bangladesh. Subjects were cluster-randomized to various elicitation methods: open-ended, dichotomous choice (at one of two asking prices), payment card (one of two cards with differing ranges). The dichotomous choice method was then followed up with a bidding game methodology, with the dichotomous choice price acting as the starting price for the bidding game. Analysis focused on summary statistics, demand curve estimation and multivariate regression analysis to test for validity and bias.Results:Thirty-one households refused to participate, leaving a total of 330 participating households (a 91.4 percent response rate). Willingness to pay estimates varied significantly across the methods (p< .001), with average estimates varying between $2.34 and $18 (US). The open-ended elicitation method was found to produce highly inflated values that were insensitive to construct validity tests. The dichotomous choice method produced quantity (demand) estimates rather than value estimates, and there was some evidence of yea saying. The payment card elicitation method was found to be affected by range bias. The bidding game elicitation method was found to be less sensitive to starting point bias and yea-saying.Conclusions:Different elicitation format do give rise to different demand curves; however, this may be partially due to the fact that they do not measure the same outcome. For example, the dichotomous choice format produces a demand curve, while the payment card, open-ended and bidding game produce inverse demand curves. All formats are prone to multiple biases. When choosing an elicitation format, it is important to first consider the purpose and use of the data. Each elicitation method has strengths and weaknesses and can be used for different purposes in technology assessment.

P Sources

Sources of bias in confidence and probability judgments, for example conservatism, overconfidence, and subadditivity, are some of the most important and rigorously researched topics within judgment and decision making. However, despite the seemingly obvious importance of memory processes on these types of judgments, much of this research has focused on external factors independent of memory processes, such as the effects of various types of elicitation format. In this chapter, we review the research relevant to commonly observed effects related to confidence and probability judgment, and then provide a memory-process account of these phenomena based on two models: Minerva-DM, a multiple-trace memory model; and HyGene, an extension of Minerva-DM that incorporates hypothesis generation. We contend that accounting for the dependence of judgments on memory provides a unifying theoretical framework for these various phenomena, as well as cognitive models that accurately reflect real-world behavior.

scholarly journals Investigating Consumer Demand and Willingness to Pay for Fresh, Local, Organic, and “On-the-Stalk” Edamame

Shopping Location

Introduction of locally adapted, commercially viable edamame varieties can allow it to be marketed as fresh, local, organic, or on the stalk. Here, we utilized a one-and-one-half bounded (OOHB) elicitation format to estimate mean willingness to pay (WTP) for these external attributes in relation to a vector of explanatory variables. Results showed 84-, 85-, and 28-cent premiums for fresh, local, and organic edamame (10 oz). Pro-environmental attitudes drove WTP for all three of these attributes, while shopping location significantly increased mean WTP for fresh and organic attributes. A 40-cent price discount was observed for the “on-the-stalk” attribute, suggesting that convenience also plays an important role in marketing edamame. The results suggest that more research regarding edamame demand is warranted.

The Impact

Cases of clear scientific misconduct have received significant media attention recently, but less flagrantly questionable research practices may be more prevalent and, ultimately, more damaging to the academic enterprise. Using an anonymous elicitation format supplemented by incentives for honest reporting, we surveyed over 2,000 psychologists about their involvement in questionable research practices. The impact of truth-telling incentives on self-admissions of questionable research practices was positive, and this impact was greater for practices that respondents judged to be less defensible. Combining three different estimation methods, we found that the percentage of respondents who have engaged in questionable practices was surprisingly high. This finding suggests that some questionable practices may constitute the prevailing research norm.
