Return of the inoperability

There has been unrest in the research community investigating the inoperability of an economic system under disaster situations. The inoperability input–output model (IIM), which is very popular in the risk management field, has become a center of argument, particularly from the input–output researchers, that IIM is a straightforward application of the standard Leontief input–output model. This paper revisits the concept of inoperability, rather than IIM, and proposes its new role in disaster impact analysis using a conventional tool, i.e. the RAS method, for illustrating how the inoperability of an economic system in the aftermath of disaster can be evaluated. The proposed framework is employed to examine the inoperability of industries resulting from the 1995 Kobe earthquake. The findings of the analysis reveal the usefulness of inoperability concept that can even incorporate resilience (gained operability) using the proposed framework of this paper.     

Measuring industrial upgrading: applying factor analysis in a global value chain framework

ABSTRACT

A key question for promoting international competition is how to improve the position of countries and industries in global value chains (GVCs). The first step is to properly measure industrial upgrading in GVCs. This is not a trivial issue because upgrading has not been defined unambiguously. Several authors have used different (and sometimes related) measures, all of which indicate certain aspects of upgrading. Rather than trying to find the single, ultimate measure of upgrading, we propose a different approach. We examine the multidimensionality of industrial upgrading, using eight indicators in factor analysis. Four of the eight indicators adopt the GVC perspective and include, for example, the growth of the share in value-added exports. We provide three quantitative dimensions of industrial upgrading: process upgrading, product upgrading, and skill upgrading. With these dimensions, we compare and analyze the upgrading of different countries and industries using the World Input–Output Database.     

Towards a hybrid model? A systematic review of human resource management research on Chinese state-owned enterprises (1993–2017)

Abstract

Over the past two decades, there has been a proliferation of research on human resource management (HRM) in Chinese state-owned enterprises (SOEs) as a result of the wide-reaching state-sector reform of the late 1980s. This article aims to provide a systematic review of literature on this topic and capture the nature of HRM in Chinese SOEs, both in research and practice. The article draws on 178 studies from 43 English academic journals over a period of 25?years (1993–2017). In analysing this literature and by taking stock of theoretical frameworks, research methods, themes and analysis of academic articles in this area, we have gained a number of insights. The study has found that the research methods used have shifted from qualitative and interpretive methodology toward quantitative and sophisticated modelling. A further insight is that there has been a relatively heavy reliance on institutional theory in the earlier studies reviewed, and since then a switch towards organizational behaviour perspectives. The level of analysis has moved from macro to micro level and thematic foci have become more diverse and complex. We highlight a number of avenues, theoretical and empirical, for future studies in this field.     

领导风格和团队冲突控制的实验研究

在团队决策过程中,冲突在所难免。单纯的任务冲突能促使成员交换不同意见,更深刻地理解团队任务,有利于提高团队决策绩效;但任务冲突往往又会引发关系冲突,关系冲突一旦产生,就会对整个团队的决策绩效产生较大的负面影响。要提高团队决策绩效,关键在于有效抑制任务冲突向关系冲突的转化。鉴于团队领导能够显著影响团队的内部互动及团队结果,本研究在团队决策过程中引入了领导风格这一变量,通过行为实验模拟团队决策过程,来对比研究务实型领导风格和魅力型领导风格对任务冲突和关系冲突之间关系的影响。结果表明,务实型领导风格比魅力型领导风格更能有效抑制任务冲突向关系冲突的转化。     

Organizational Culture,Leadership Behaviors,and Employee Attitude in Chinese SMEs＂ Empirical Evidence

This study examines the impact of organizational culture on leadership behaviors, as well as the influence of leadership behaviors on employee attitude in Chinese small and medium-sized enterprises （SMEs）. Based on previous researches, this study establishes a conceptual model that indicates the two types of influential relationship. Data are collected from 515 subordinates of 23 SMEs in Chengdu of Sichuan province. By using statistical methods, findings of this study are concluded. Directions for future research are also discussed.     

Fair value disclosures and crash risk

In response to the public criticism of the inadequate disclosures mandated by SFAS No. 157, Fair Value Measurements, the FASB issued ASU (Accounting Standards Update) 2010–06, Improving Disclosures about Fair Value Measurements, and ASU 2011–04, Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements, in an effort to increase the reporting transparency. We examine whether the increased fair value disclosures required by these two updates effectively decrease crash risk, defined as the frequency of extreme negative stock returns. In support of the hypothesis, we find that increased transparency from these updates reduces crash risk among U.S. banking firms and that the reduction is greater in banks that have a higher level of Level 3 financial assets.     

论公共和市场两种不同类型的失信惩戒机制及其互补关系

失信惩戒机制是社会信用体系的核心构件之一,完整的失信惩戒机制由公共型失信惩戒机制和市场型失信惩戒机制共同组成.公共型失信惩戒机制使用公权力,可用作政府治理社会和市场信用监管的工具,主要在信控的事后处理区段对严重失信违规的市场主体实施行政处罚,其惩戒力度和震慑力非常强.它虽然只作用于国内,却能覆盖市场和社会领域.市场型失...     

住宅市场量价关系分析——基于香港数据的实证研究

本文基于滤波方法-9向量自回归模型，对香港十多年的住宅交易量和价格数据进行实证研究。结果显示，考察1996．1-1997．6区间的样本交易量与价格互为格兰杰因果关系，表现出正反馈效应，投机现象非常明显。但当选取1997．7-2007．7区间的样本则仅发现价格是交易量的格兰杰原因，并不存在双向因果关系。方差分解结果表明，交易量波动对于价格波动的影响要大于价格波动对于交易量的影响。     

Optimal pair-trading strategy over long/short/square positions—empirical study

Suzuki [Automatica, 2016, 67, 33–45] solves the optimal, finitely iterative, three-regime switching problem for investing in a mean-reverting asset that follows an Ornstein–Uhlenbeck price process and find explicit solutions. The remarkable feature of this model is that the investor can explicitly take either a long, short or square position and can switch the position, with transaction costs, during the investment period. We run empirical simulations of such multiple-regime switching models. There are very few such attempts in the existing literature because it is difficult to find, first, an explicit solution to the problem and second, appropriate financial assets that follow the artificial stochastic process required by the mathematical model. According to the Monte Carlo simulations of the optimal pair-trading strategy, the mean daily Sharp ratio is more than 2.3, whereas the mean Sharp ratio for the historical simulation of the ‘stub’ pairs (combinations of parent/subsidiary companies) is 0.6886. We believe that the results obtained from performing the empirical simulations are remarkable and consider that the optimal switching strategy of the rigorous mathematical model is applicable to businesses in the real world. For the reference many pseudo-program codes are added, which can help to replicate the optimal trading strategies.     

The role of perceived costs and perceived benefits in the relationship between personality and risk‐related choices

This paper considers how perceptions of costs and benefits can influence the association between personality and risky choice behaviour. We assessed perceptions and behaviours in six domains (ethical; investment; gambling; health and safety; recreational; social) using the DOSPERT and measured personality using the NEO PI‐R. Results from structural equation modelling showed that personality had a direct effect on risky choice behaviour in four domains (social, ethical, gambling and recreational risk‐taking). In addition, perceived costs and benefits mediated the relations between personality and risk‐taking in the five domains (social, ethical, gambling, recreational and investment risk‐taking). Evidence for a mechanism that integrates both direct and indirect effects of personality on behaviour is discussed.
