What happens, however, when people are asked to exchange an ambiguous alternative in their possession for an unambiguous one? We present three experiments in which individuals preferred to retain the former. This status quo bias emerged both within- and between-subjects, with and without incentives, with different outcome distributions, and with endowments determined by both the experimenter and the participants themselves. Findings emphasize the need to account for the frames of reference under which evaluations of probabilistic information take place as well as modifications that should be incorporated into descriptive models of decision making. Keywords Ambiguity, risk, status quo bias, decision making, uncertainty. JEL code: C91, D81. 2 The phenomenon of ambiguity aversion – or the preference for gambles with known as opposed to unknown probabilities – has been well documented in the literature on decision making in both psychology and economics (see, e.g., Ellsberg, 1961; Camerer & Weber, 1992; Keren & Gerritsen, 1999). -

Among other things, the authors consider some relevant facets of the social and institutional environments in which the poor interact, and they review some behavioral patterns that are likely to arise in these contexts. A behaviorally more informed perspective can help make sense of what might otherwise be considered “puzzles” in the economic comportment of the poor. A behavioral analysis suggests that substantial welfare changes could result from relatively minor policy interventions, and insightful marketing may provide much needed help in the design of such interventions. -
Cognitive Bias in Emissions Trading
sustainability Article Cognitive Bias in Emissions Trading Jae-Do Song 1 and Young-Hwan Ahn 2,* 1 College of Business Administration, Chonnam National University, Gwangju 61186, Korea; [email protected] 2 Korea Energy Economics Institute, 405-11 Jongga-ro, Jung-gu, Ulsan 44543, Korea * Correspondence: [email protected]; Tel.: +82-52-714-2175; Fax: +82-52-714-2026 Received: 8 February 2019; Accepted: 27 February 2019; Published: 5 March 2019 Abstract: This study investigates whether cognitive biases such as the endowment effect and status quo bias occur in emissions trading. Such cognitive biases can serve as a barrier to trade. This study’s survey-based experiments, which include hypothetical emissions trading scenarios, show that the endowment effect does occur in emissions trading. The status quo bias occurs in only one of the three experiments. This study also investigates whether accumulation of experience can reduce cognitive bias as discovered preference hypothesis expects. The results indicate that practitioners who are supposed to have more experience show no evidence of having less cognitive bias. Contrary to the conventional expectation, the practitioners show significantly higher level of endowment effect than students and only the practitioners show a significant status quo bias. A consignment auction situation, which is used in California’s cap-and-trade program, is also tested; no significant difference between general permission trading and consignment auctions is found. Keywords: emissions trading; cognitive bias; consignment auction; climate policy 1. Introduction Emissions trading allows entities to achieve emission reduction targets in a cost-effective way through buying and selling emission allowances in emissions trading markets [1,2]. -

Cognitive Biases in Software Engineering: a Systematic Mapping Study
Cognitive Biases in Software Engineering: A Systematic Mapping Study Rahul Mohanani, Iflaah Salman, Burak Turhan, Member, IEEE, Pilar Rodriguez and Paul Ralph Abstract—One source of software project challenges and failures is the systematic errors introduced by human cognitive biases. Although extensively explored in cognitive psychology, investigations concerning cognitive biases have only recently gained popularity in software engineering research. This paper therefore systematically maps, aggregates and synthesizes the literature on cognitive biases in software engineering to generate a comprehensive body of knowledge, understand state of the art research and provide guidelines for future research and practise. Focusing on bias antecedents, effects and mitigation techniques, we identified 65 articles (published between 1990 and 2016), which investigate 37 cognitive biases. Despite strong and increasing interest, the results reveal a scarcity of research on mitigation techniques and poor theoretical foundations in understanding and interpreting cognitive biases. Although bias-related research has generated many new insights in the software engineering community, specific bias mitigation techniques are still needed for software professionals to overcome the deleterious effects of cognitive biases on their work. Index Terms—Antecedents of cognitive bias. cognitive bias. debiasing, effects of cognitive bias. software engineering, systematic mapping. 1 INTRODUCTION OGNITIVE biases are systematic deviations from op- knowledge.

Dynamic Collective Choice with Endogenous Status Quo∗
Dynamic Collective Choice With Endogenous Status Quo Wioletta Dziuday Antoine Loeperz August 2014 First version: December 2009 Abstract This paper analyzes an ongoing bargaining situation in which preferences evolve over time and the previous agreement becomes the next status quo, determining the payoffs until a new agreement is reached. We show that the endogeneity of the status quo induces perverse incen- tives that exacerbate the players’ conflict of interest: Players disagree more often than they would if the status quo was exogenous. This leads to ineffi ciencies and status quo inertia. When players are suffi ciently patient, the endogenous status quo can lead the negotiations to a com- plete gridlock in which players never reach an agreement even though their preferences agree arbitrarily often. When applied to the legislative setting, our model predicts partisan behavior, and explains why oftentimes legislators fail to react in a timely fashion to economic shocks. JEL Code: D72.

Steele a,¤, Nalini Ambady b a Department of Psychology, York University, Atkinson Faculty of Liberal and Professional Studies, Ont., Canada M3J 1P3 b Department of Psychology, Tufts University, 490 Boston Avenue, Medford, MA, 02155, USA Received 11 May 2005; revised 6 June 2005 Available online 19 August 2005 Abstract In three studies, we examined the eVect of a self-relevant category prime on women’s attitudes towards the gender-stereotyped domains of arts (positively stereotyped) and mathematics (negatively stereotyped). In Study 1, women who were subtly reminded of the category female (Study 1a) or their gender identity (Study 1b) expressed more stereotype consistent attitudes towards the aca- demic domains of mathematics and the arts than participants in control conditions. In Study 2, women who were reminded of their female identity similarly demonstrated a stereotype-consistent shift in their implicit attitudes towards these domains relative to women in a control condition. The potential role of the working self-concept in mediating social category priming eVects as well as the practical implications of these Wndings are discussed. © 2005 Elsevier Inc.

Rule1, Jonathan B. Freeman2, and Nalini Ambady3 1Department of Psychology, University of Toronto, Toronto, Canada 2Department of Psychology, Tufts University, Boston, MA, USA 3Department of Psychology, Stanford University, Stanford, CA, USA The aim of this review is to highlight an emerging field: the neuroscience of culture. This new field links cross– cultural psychology with cognitive neuroscience across fundamental domains of cognitive and social psychology. We present a summary of studies on emotion, perspective-taking, memory, object perception, attention, language, and the self, showing cultural differences in behavior as well as in neural activation. Although it is still nascent, the broad impact of merging the study of culture with cognitive neuroscience holds mutual distributed benefits for mul- tiple related fields.
