A cognition paradigm clash: Simon,situated cognition and the interpretation of bounded rationality

Simon’s notion of bounded rationality is deeply intertwined with his activity as a cognitive psychologist and founder of so-called cognitivism, a mainstream approach in cognitive psychology until the 1980s. Cognitivism, understood as ‘symbolic information processing,’ provided the first cognitive psychology foundation to bounded rationality. Has bounded rationality since then fully followed the development of cognitive psychology beyond symbolic information processing in the post-Simonian era? To answer this question, this paper focuses on Simon’s opposition during the 1990s to a new (paradigmatic) view of cognition called situated cognition, which has since put into question the entire view in cognitive psychology of humans as symbolic information processors. This paper then reads the cognitivism/situated cognition debate through the lens of current bounded rationality research in economics, in order (i) to inquire into whether it has tackled the issues in that controversy; (ii) to envisage possible new foundations for a cognitive psychology-based bounded rationality.     

Hooliganism and Demand for Football in Italy: Attendance and Counterviolence Policy Evaluation

This paper empirically investigates the relationship between stadium attendance, hooliganism and counter‐violence policy measures in Italian Serie A. In particular, this paper analyses the impact of counter‐hooliganism policies adopted in 2007 on the quantity of game tickets sold. The counter‐hooliganism measures, grounded on an entry card, namely a ‘fidelity card’, were designed to keep out hooligans from stadiums so favouring the attendance of either occasional spectators or uncommitted fans. According to our econometric investigation the expected substitution between committed fans and uncommitted fans did not take shape. In sum, the ‘fidelity card’ did not turn to be successful if evaluated on the average attendance perspective.     

The evolution of rationality and the Red Queen

Strategic rationality is subjected here to natural selection. In a zero-sum repeated game of incomplete information, one long-run individual is informed of the state of the world, and plays against a sequence of short-run opponents who are not. Strategies are noisy and have bounded recall. An equilibrium in these is shown to exist. Relative to any such equilibrium, sufficiently greater recall enjoys an advantage that is not decreasing in the original level of recall, thus capturing the Red Queen effect. The selection pressure to reduce a small amount of noise is less than that to increase recall.

西藏旅游人力资源需求内因分析

西藏旅游企业从业人员规模还十分弱小,特别是旅游企业中导游队伍有待开发.而随着社会经济的发展以及结构的调整,旅游就业总量将不断增长,就业结构也会趋于合理;同时,西藏旅游开发战略模式决定了其从业人员的专业性和多样性,西藏4A级旅游区(点)的发展及扩增也将扩大就业人群.     

开放催生“双城记”

在中国,省会城市无疑是各省的龙头,在方方面面遥遥领先省内其他城市。尤其是前些年,省会城市在省内处于绝对的“垄断”地位。然而,改革开放以后,情况就大不一样,有发展较快的城市敢与省会叫板,致使省会城市“一城独大”的地位在削弱。笔者认为这是好现象,城市问可以在互相挑剔、取长补短、比拼式发展中跳跃前行……。     

并购商誉、商誉减值与股票错误定价

以近年来上市公司频发的并购重组为背景,选取2007—2019年我国沪深A股上市公司为研究样本,实证检验了并购商誉对股票错误定价的影响。研究发现,商誉加剧了并购方的股票错误定价,高商誉的公司股价被严重高估,计提商誉减值能够向投资者传递增量信息,缓解商誉导致的股票错误定价。进一步研究发现,会计稳健性和投资者情绪在并购商誉对股票错误定价的影响中发挥了部分中介作用。商誉对股票错误定价的影响在管理层持股高、分析师跟踪人数多的情况下更为显著,上市公司大股东及管理层存在利用并购商誉导致的股价高估实现高位减持的行为。研究结论有助于投资者对并购商誉正确定价,提高资本市场定价效率。

An updated ranking of academic journals in economics

Abstract We conduct an update of the ranking of economic journals by Kalaitzidakis, Mamuneas, and Stengos (2003) . However, our present study differs methodologically from that earlier study in an important dimension. We use a rolling window of years between 2003 and 2008, for each year counting the number of citations of articles published in the previous 10 years. This allows us to obtain a smoother longer view of the evolution of rankings in the period under consideration and avoid the inherent randomness that may exist at any particular year, because of new entrants.
