Cue-recognition effects in the assessment of movie trailers

In the past, the role of recognition in inferential choice has often been investigated within the recognition heuristic (RH) that focuses on the recognition of options. In the present study I investigate instead whether the recognition of a cue influences the assessment of movie trailers. This extension of the RH to cues provides important and more comprehensive insights into recognition in everyday decision-making. One hundred and eighty-eight participants were randomly assigned to one paired comparison and had to decide which of two movie trailers (Epic and The Croods) was about to become more successful. All pairwise comparisons consisted of the same two unknown animated movie trailers. They differed merely from a fade-in of a short unknown or known movie title (e.g., “From the makers of Ice Age”). The central objective of this study was to test whether or not the participants judged movie trailers to be more successful and likeable when associated with the famous movie title and thus decide on the basis of the recognition of this cue. In fact, it was shown that people in this context often revert to this recognition cue. However, the prerequisite for this effect was that the faded-in title should be appropriate for the trailer. Furthermore the preference of animated films was identified as a key factor. Volunteers who liked animated films less, often decided due to the recognized cue. Moreover it is shown that participants increasingly use the recognized cue to decide if they specify a preference and high success for this faded-in movie.

出口信用保险市场是否存在代表性启发效应

基于贝叶斯概率模型,采用2009—2019年的省级面板数据,通过动态GMM回归分析出口信用保险市场是否受到代表性启发效应的干扰。研究表明：受制于代表性启发的决策者扭曲未来损失的概率估计,形成损前投保不足、损后过度投保的需求模式;代表性启发确实影响我国出口信用保险的需求市场,但时间递减效应不显著。     

Is Process as Important as Outcome？ Empirical Evidence from the Chinese Context

Although the relationship between pay level and pay satisfaction has been verified as one of the most robust relationships in the literature of pay satisfaction, scholars have not yet reached an agreement regarding its underlying mechanisms. The present paper aims to investigate the link between absolute pay level and pay level satisfaction by introducing both distributive and procedural fairness perceptions as mediators in accordance with fairness heuristic perspective. A sample of 298 employees from various types of organizations completed a survey, and a series of models were compared to evaluate if the hypothesized theoretical model fits our data. We also constructed bias-corrected bootstrap confidence intervals to test the hypothesized mediation effects. The suggested theoretical model is supported, and future research directions are discussed.

Proximity changes to what and for whom? Investigating sustainable accessibility change in the Gothenburg city region 1990–2014

This paper operationalizes the concept of sustainable accessibility by emphasizing the environmental and social dimensions of sustainability from a spatial perspective. In doing so, we develop a heuristic model that focuses on the crucial dimensions of who gets access to what by using sustainable means of movement. We apply our conceptual approach in an examination of trends in sustainable accessibility for different social groups living in Gothenburg, Sweden between 1990 and 2014. On the basis of welfare-related and time-geographical considerations, we investigate accessibility by proximity for low- and high-income earners, people with small children, and elderly people. We investigate to what extent proximity to fundamental facilities increases or decreases over time, indicating changing conditions for sustainability. The results show that opportunities for living a local life and achieving accessibility via proximity differ socially. Low-income earners and the elderly generally live closer to the facilities important for daily life than do high-income earners and parents of young children. We also show that the opportunities for various social groups to obtain access by proximity change over time. For example, we observe a trend in which over time older people face reduced opportunities to reach daily facilities in their local neighborhoods.     

The Effect of CEO Extraversion on Analyst Forecasts: Stereotypes and Similarity Bias

In an experiment with professional analysts, we study their reliance on CEO personality information when producing financial forecasts. Drawing on social cognition research, we suggest analysts apply a stereotyping heuristic, believing that extraverted CEOs are more successful. The between‐subjects results with CEO extraversion as treatment variable confirm that analysts issue more favorable forecasts (earnings per share, long‐term earnings growth, and target price) for firms led by extraverted CEOs. Increased forecast uncertainty leads to even stronger stereotyping. Additionally, personality similarity between analysts and CEOs has a large effect on financial forecasts. Analysts issue more positive forecasts for CEOs similar to themselves.
