Abstract

Purpose

Bat algorithm (BA) is a global optimization method, but has a worse performance on engineering optimization problems. The purpose of this study is to propose a novel chaotic bat algorithm based on catfish effect (CE-CBA), which can effectively deal with optimization problems in real-world applications.

Design/methodology/approach

Incorporating chaos strategy and catfish effect, the proposed algorithm can not only enhance the ability for local search but also improve the ability to escape from local optima traps. On the one hand, the performance of CE-CBA has been evaluated by a set of numerical experiment based on classical benchmark functions. On the other hand, five benchmark engineering design problems have been also used to test CE-CBA.

Findings

The statistical results of the numerical experiment show the significant improvement of CE-CBA compared with the standard algorithms and improved bat algorithms. Moreover, the feasibility and effectiveness of CE-CBA in solving engineering optimization problems are demonstrated.

Originality/value

This paper proposed a novel BA with two improvement strategies including chaos strategy and catfish effect for the first time. Meanwhile, the proposed algorithm can be used to solve many real-world engineering optimization problems with several decision variables and constraints.

Abstract

Purpose

This study examines how Confucianism, as an informal system, alleviates manager–shareholder conflicts and thus decreases managerial behavior of keeping higher levels of cash reserves. This study also investigates whether formal governance mechanisms (state ownership and institutional investors) moderate the relationship between Confucianism and cash holdings.

Design/methodology/approach

This study opts a sample of Chinese listed firms over the period of 2004–2015. The geographical-proximity-based method was followed to measure Confucianism, which is the distance between a firm's registered address and the national Confucianism centers.

Findings

The results indicate that Confucianism adversely influences cash holdings. The authors’ findings illustrate that Confucian culture promotes ethical behavior, and therefore, firms in a strong Confucianism environment keep a lower level of cash reserves. The authors further document that the effect of Confucianism on cash holding is weaker for state-owned firms but stronger for firms with low institutional ownership.

Practical implications

The findings provide implications for policymakers, academicians, and corporations. The results suggest that culture can reduce cash holdings. Especially, in emerging markets, such as China, where formal mechanisms are relatively less effective, informal institutions can serve an alternative system for alleviating adverse effects of agency conflicts.

Originality/value

This study contributes to the literature in two ways. First, this study contributes to cash holdings literature by showing that culture (Confucianism) is negatively associated with cash holdings. Second, this study extends the incumbent literature that seeks to explore how Confucian culture influences corporate behavior. To the best of the authors knowledge, this is the first study that identifies that Confucianism is associated with cash holdings.

Abstract

Purpose

Anchored in the role of a social arbiter, the purpose of this study is to examine whether and how media coverage has an impact on CEO overconfidence and further explore how media ownership and Confucianism affect the relationship in the Chinese context.

Design/methodology/approach

Using a sample of 1,492 Chinese listed companies from 2010 to 2015, the study adopts random effects models to empirically analyze the effect of media coverage on CEO overconfidence and the roles of media ownership and Confucianism.

Findings

The paper finds that media coverage is significantly and positively associated with CEO overconfidence, and the positive relationship between media coverage and CEO overconfidence becomes stronger for state-controlled media. What is more, the influence of media coverage on CEO overconfidence is attenuated for those firms located in stronger Confucianism atmosphere. A further analysis reveals that different tenors of media coverage yield asymmetric effects.

Originality/value

The paper provides a new and solid support for the argument that media praise stimulates CEO overconfidence and increases the knowledge about under what conditions CEO overconfidence varies, broadly speaking which fosters the development of upper echelons theory (UET). Meanwhile, the results extend the literature on media effect and information processing. The findings are also beneficial to improve corporate decisions and government regulation on Chinese media systems.

Abstract

Wonders whether, owing to severely restricted access, China’s government policy towards digital communications will remain in a constant state of flux – or will it gain economic benefits without a social penalty? Concludes that China has to link the forces of change to channel and deflect domestic resistance.
