Sunk cost sensitivity in mice, rats, and humans on the Restaurant Row and WebSurf tasks cannot be explained by attrition biases alone

In a recent bioRxiv preprint, Ott et al. argue that sensitivities to sunk costs that have been reported in two serial foraging tasks (the Restaurant Row task in mice and rats, and the Web-Surf task in humans) may be due to simple consequences of the way that subjects perform these tasks and not due to an actual sensitivity to sunk costs. However, several variants of these tasks have been studied, in which the sensitivity to sunk costs changes. In order to test the Ott et al. model against these experimental observations, we simulated the model under these additional experimental conditions. We find that it is incompatible with the actual data. While we applaud the simplicity of the Ott et al. model, we must reject it as an explanation for the observed sensitivity to sunk costs seen in these tasks. We thus conclude that the alternative explanation - that mice, rats, and humans are sensitive to actual sunk costs in these tasks - is a better explanation for the data.

Environmental Management through Coopetitive Urban Waste Recycling in Eco-Industrial Parks

In this article, we consider the coexistence of competing actors within a specific eco-industrial park. The competing firms dynamics evolves by means of an interplay agreement determined among the competitors themselves. In particular, we show a possible scenario in which the selected eco-industrial competitors could greatly benefit from a coopetitive interaction, within their common eco-park, while improving the general conditions of a near residential area. The associated dynamical coopetitive agreement, aims at the growth and improvement of the firms themselves and of their industrial network (within a virtuous environmental path). As an example, we assume the existence of two competitors selling the same good on the same market, so that, from a competitive point of view, we construct a classic Cournot duopoly model upon which we build up a multidimensional coopetitive agreement. Our eco-friendly deal allows to “enlarge the pie” of possible gains by diminishing sunk costs and other forms of costs, especially the environmental costs associated to the management of urban waste recycling. Consequently, we suggest production methods and production quantitative profiles in order to “share the gains fairly”. We show a complete mathematical analysis of our new economic game and show some of its possible and relevant solutions.

Escalation of Commitment: Supporting Role from Accountants

Previous research has mostly examined the phenomenon of escalation of commitment in the context of decision making by managers in an investment project. However, in the capital budgeting process, before making investment decisions managers tend to consider information produced by accountants. This study examines the phenomenon of escalation of commitment using the perspective of supporting role of accountants as the party that provides information for investment decision making by managers, especially in the presence of sunk costs. This study uses a laboratory experimental method. The sample in this study are 156 undergraduate students majoring in Accounting who had passed Financial Accounting and Management Accounting courses. Based on the results of the independent sample t-test, it shows that accountants who experienced sunk cost conditions tend to provide reports that directed managers towards escalation of commitment behavior compared to accountants who do not experience sunk cost conditions. The presence of sunk cost makes accountants have better mind frame to get the possibility of profit compared with a definite loss so that the decisions they make tend to provide reports that lead to the escalation of commitment behavior.

O efeito Sunk Cost no Processo Decisório dos discentes de Instituições de Ensino Superior

O objetivo deste estudo foi verificar a influência do efeito sunk cost nas decisões, gerenciais e pessoais, tomadas pelos discentes do Curso de Ciências Contábeis das Instituições de Ensino Superior. A pesquisa caracterizou-se como descritiva e de levantamento com abordagem quantitativa. Foram aplicados questionários a discentes de cinco Instituições de Ensino Superior que possuíam o curso Ciências Contábeis, na modalidade presencial. A coleta de dados, realizada nos meses de outubro e novembro de 2019, foi realizada fazendo uso de um questionário, adaptado do modelo de Domingos (2007), Rover et al. (2009) e Segantini et al. (2011) e, quanto aos dados levantados, utilizou-se a análise descritiva das respostas dos participantes e também se empregou o teste estatístico do qui-quadrado (χ2) para testar a significância entre as respostas obtidas. Os resultados encontrados evidenciaram que o valor do custo irrecuperável pode influenciar na ocorrência do efeito sunk costs. Isto pode ser constatado, pois à medida que diminuía o montante do custo perdido, menor era a disposição dos discentes em prosseguir investindo nos cursos de ação que deveriam ser abandonados. Quando a decisão é voltada para o contexto pessoal, os discentes levaram em consideração a premissa de aversão ao desperdício e senso de responsabilidade.
