Augmenting short Cheap Talk scripts with a repeated Opt-Out Reminder in Choice Experiment surveys (2014, result): “…effect of CT has been tested extensively in subsequent CVM studies, and the results here are much more ambiguous (Aadland and Caplan 2003; 2006; Ami et al. 2009; Barrage and Lee 2010; Brown et al. 2003; Carlsson and Martinsson 2006; List 2001; 2003; Morrison and Brown 2009; Murphy et al. 2005a).”
What's to Know About Hypothetical Bias in Stated Preference Valuation Studies? (2011, unknown): “Limited existing evidence suggests that recoding respondents who report a level of certainty less than ‘seven’ on a 1–10 certainty scale, or less than ‘definitely sure’ in the narrative scale, as ‘no’ responses yields a hypothetical WTP that matches actual cash WTP reasonably well (Ethier et al., 20”
From Exxon to BP: Has Some Number Become Better Than No Number? (2012, background): “Morrison and Brown (2009) provide a summary and reference list of studies related to both the cheap talk, and certainty scale follow-up, methods.”
Hypothetical bias in stated choice experiments: Part II. Macro-scale analysis of literature and effectiveness of bias mitigation methods (2021, result): “Similar promising findings were reported for other CV methods (Blumenschein et al., 2007; Harrison and Rutström, 2008), including referendums (Morrison and Brown, 2009), dichotomous choice experiments (Brouwer, 2011; Vossler et al., 2003) and auctions (Furno et al., 2019).”
2013WAEA Keynote Address: Strategies for Overcoming Hypothetical Bias in Stated Preference Surveys (2014, methodology): “The limited evidence suggests that recoding respondents with a certainty level of less than seven (or definitely sure in the narrative scale) matches actual cash donations reasonably well (Ethier et al., 2000; Morrison and Brown, 2009; Blumenschein et al., 2008).”
Understanding Hypothetical Bias: An Enhanced Meta‐Analysis (2018, unknown): “As stated before, some studies (e.g., Loomis et al. 1996; Morrison and Brown 2009) report multiple measures of WTP, such as mean and median WTP, per good.”
