I specifically aimed to answer the following questions: Research Question #1: Do marketing researchers separate the concepts of response rate from response bias? Research Question#2: How exactly should data quality be measured? Is it about sample representativeness, minimizing non- response bias or just solely Increasing the response rate? Research Question#3: What are researchers doing to assess and minimize response bias? Research Question#4: Do additional efforts put forth by survey researchers, such as reminder letters and incentives, for the purpose of increasing survey response rate affect additional sampling bias? Research Question#5: Are the common techniques used by survey researchers to increase response rate equally effective? In an attempt to answer the research questions stated, I have collected both primary and secondary data. The primary data was collected from the Academy of Marketing Science active members. Eight versions of an excerpt was prepared that is taken from an actual article that was accepted for publication recently. The experimental design adopted was 2x2x2 with each treatment trying to answer one of the research questions stated in this study. iii iv The first treatment was regarding the consideration of population. The subjects were manipulated with two versions of the excerpt of which one was with a Canadian sample and the second was with a so called North American sample. The second treatment was about the manipulation of the initial number of surveys sent out which as a result would change the response rate percentage. The two different versions included 500 vs. 5000 initial surveys sent out varying the response rate from 5.1% to 50.2%. The third treatment included the manipulation of Armstrong and Overton (1977) citation. The over use of this citation in the marketing literature has been noteworthy. In an attempt to investigate this matter further, this treatment was created. First version contained a sentence that stated that the early and the late respondents were compared and no significant differences were found as evidence of no response bias including the citation of Armstrong and Overton (1977). The second version of the excerpt included a table with the expected demographics regarding the population of interest. In addition to these, the subjects were also assigned to two different conditions where they were asked to evaluate the excerpt as an author or as a reviewer. In the invitation email respondents were asked to toss a coin or to click on a web link that would toss the coin for them and select the appropriate link that corresponds with their choice. In order to assess the popular techniques of enhancing response rate, I have divided the sample into several groups as the pre-notification, the reminder and the pre- notification and reminder groups and a control group that received neither the reminder V nor the pre-notification treatment. The results revealed that, according to my sample none of the techniques mentioned above, improve the response rate. The secondary data was collected from major outlets of the marketing science {Journal of Marketing- JM, Journal of Marketing Research-JMR, and Journal of the Academy of Marketing Science-}AMS) during the periods of 2005-2010. The final sample consisted of 68 JM, 23 JMR and 84 JAMS articles. In addition to these, I also randomly selected 31 rejected articles from the Journal of Business Research (JBR) archives. The results of the study revealed that, survey researchers do not clearly grasp the concepts of response rate and response bias. In addition, the results demonstrated that the data quality should be measured by the sample's representativeness of the population and the researcher's capability of decreasing the response and the non-response biases. Further, the techniques used to enhance response rate such as reminder and pre- notification letters as well as incentives are not as effective and are likely to introduce additional response bias to a study. The results also showed that the optimal data collection method researchers should consider adopting is the combination method. The study ends with the discussion of the implications of these results and possible future extensions of this study.

    Running head: GENERAL MISCONCEPTIONS AND THINKING STYLES 1 A new measure of general misconceptions: Relations with rational, intuitive, critical thinking, and monetary incentives Marle Wortelboer Master thesis Economic Psychology Tilburg School of Social and Behavioral Sciences 1st Supervisor: W.W.A. Sleegers 2nd Supervisor: F. van Leeuwen March 22th 2019 GENERAL MISCONCEPTIONS AND THINKING STYLES 2 Abstract Past research indicated several issues regarding measurements of (psychological) misconceptions. In this paper, it was aimed to develop a new Test of General Knowledge and Misconceptions (TOGKAM) based on recent suggestions to address previous limitations of Bensley et al. (2014). In order to validate this TOGKAM, relations with rational- and intuitive thinking styles and critical thinking dispositions were tested. It was hypothesized that an Intuitive-Experiential thinking style was positively correlated with TOGKAM scores, whereas a Rational-Analytic thinking style and Critical Thinking dispositions were negatively correlated with TOGKAM scores. In addition, it was examined whether monetary incentives decreased the endorsement of misconceptions. Hypothesized was, that incentivized participants were more likely to use rational and analytic thinking styles and subsequently endorsed fewer misconceptions. Results of this study supported all the hypotheses. Keywords: misconceptions, intuitive- and rational thinking styles, critical thinking, dual- processing. GENERAL MISCONCEPTIONS AND THINKING STYLES 3 A new measure of general misconceptions: Relations with rational, intuitive, critical thinking, and monetary incentives Misconceptions are widely held beliefs that contradict established scientific evidence (Gardner & Brown, 2013; Sak, 2011). Misconceptions, or sometimes called myths, are stable and often deeply rooted beliefs about the world. Common misconceptions such as ‘bats are blind and navigate through echolocation’ or ‘the Chinese wall is the only man-made structure visible from space with the naked eye, are often part of ‘folk wisdom’ (McCutcheon, 1991).

Models for Anchoring and Acquiescence Bias in Consumption Data Arthur van Soest and Michael Hurd NBER Working Paper No. 10461 April 2004 JEL No. C81, D12 ABSTRACT Item non-response in household survey data on economic variables such as income, assets or consumption is a well-known problem. Follow-up unfolding bracket questions have been used as a tool to collect partial information on respondents that do not answer an open-ended question. It is also known, however, that mistakes are made in answering such unfolding bracket questions. In this paper, we develop several limited dependent variable models to analyze two sources of mistakes, anchoring and acquiescence (or yeasaying), focusing on the first bracket question. We use the experimental module of the AHEAD 1995 data, where the sample is randomly split into respondents who get an open-ended question on the amount of total family consumption - with follow-up unfolding brackets (of the form: is consumption $X or more?) for those who answer “don’t know” or “refuse” - and respondents who are immediately directed to unfolding brackets.

  • Using Construal Level Theory to Deter the Social Desirability Bias
    Using Construal Level Theory to Deter the Social Desirability Bias A dissertation submitted to the Division of Research and Advanced Studies Of the University of Cincinnati in partial fulfillment of the requirements for the degree of DOCTORATE OF PHILISOPHY (PH.D.) in the department of Marketing of the College of Business 2012 by Scott A. Wright B.S., Boston College Committee Members: Frank R. Kardes, Ph.D., James J. Kellaris, Ph.D., David J. Curry, Ph.D., and Rebecca Walker Naylor, Ph.D. 1 ABSTRACT Leveraging Construal Level Theory to Attenuate the Social Desirability Bias by Scott A. Wright Chair: Frank R. Kardes, Ph.D. The social desirability bias is the tendency of respondents to adjust their responses or behavior in such a way as to present themselves in socially acceptable terms. The systematic bias introduced by the social desirability bias threatens the legitimacy of empirical research by confounding a phenomenon of interest with impression management behavior, thus obscuring research results and potentially triggering false conclusions. When the social desirability bias is a concern (e.g., when asking socially sensitive, embarrassing, or private questions), researchers commonly use techniques such as indirect questioning to avoid this bias. By asking respondents how most or the typical person would respond (i.e, referring to a third party target) the respondent transcends from an egocentric focus on his or her own unflattering attitudes or behavior onto that of an ambiguous target. Given the target‘s indistinctness respondents project their own feelings, attitudes, behaviors, or beliefs when responding while remaining psychologically distanced from the true, yet socially undesirable response.

  • Lump Sum Versus Annuity: Choices of Kentucky Farmers During the Tobacco Buyout Program
    Journal of Agricultural and Applied Economics, 41,3(December 2009):613–624 Ó 2009 Southern Agricultural Economics Association Lump Sum versus Annuity: Choices of Kentucky Farmers during the Tobacco Buyout Program Helen Pushkarskaya and Maria I. Marshall Our study uses the data collected during the implementation of the tobacco buyout program in Kentucky to evaluate how rural households, diverse in income, age, family structure, location, education level, and other characteristics, made a choice between annuities and a lump-sum payment. Subjects in our field experiment did not have to retire or change their employment, as did subjects in many field studies of the choice between annuities and lump-sum payments, which allowed us to evaluate the relationship between the option choice and a decision whether to exit the tobacco market. Our results suggest that while discounted utility theory gives ac- ceptable predictions of the farmers’ behavior, other factors have to be taken into consideration. First, there are consistent biases that describe individual intertemporal behavior, such as availability bias or acquiescence bias. Second, there is a certain degree of heterogeneity in individual intertemporal preferences that correlates with their personal characteristics, such as education and production status. Third, our analysis revealed that the decision to exit the tobacco market positively correlated with the decision to take a lump-sum payment.

E-mail: [email protected] Abstract The objective of this work was to analyze, by means of an experiment, if the type (positive or nega- tive) and the level (simple or complex) of economic-financial information influence the anchoring effect of accountants and managers in a process of managerial decision-making. To do so, an exper- imental methodology targeting a sample of 86 Accountants, 68 Managers and 118 people with different professional activities (control group) was used. The results showed, in the first test with- out differentiation of factors (type and level), that about 96% of the participants have the anchoring effect, leaning towards minimum and maximum estimates of sales revenue, operating expenditure and result. In addition, the ANOVA and the Approximate Permutation Test brought significant evidence that the anchoring effect in minimum projections can be influenced by the type of infor- mation, not being significant for anchoring in maximum projections and for the level of information on both estimates (minimum and maximum).
