Analyzing the relationships between information technology, inputs substitution and national characteristics based on CES stochastic frontier production models

This research examines four interrelated issues at the country level: the value of information technology (IT), inputs substitution and complement, the complementarity phenomenon created by IT and national characteristics, and the productivity paradox, jointly and critically from a global perspective, using the so-called productive efficiency as the performance measure. To that end, we develop the three-factor constant elasticity of substitution (CES) stochastic production frontier model and apply it to a set of panel data from 15 countries over the period 1993–2003, along with the traditional two-factor CES models, within the one- and two-equation frameworks. In the two-equation setting, six national characteristics are selected as the contributing factors of the productive efficiency. The findings include: (i) the value of IT as measured by the productive efficiency is duly recognized: (ii) the productivity paradox is found to be absent from the production process in a majority of developed and developing countries considered, rejecting the existing argument that the paradox exists only in developing economies but does not exist in developed countries; however, the developed countries have used IT capital in their production systems more productively efficiently than the developing nations; (iii) traditional capital (non-IT capital), traditional labor, and IT capital are not pairwise substitutable, contrary to the notion that they are pairwise substitutable at the firm level; (iv) constant returns to scale, as commonly assumed, are not supported by the data; (v) different national characteristics affect a country's output (represented by gross domestic product or GDP) and its productive efficiency differently; and (vi) the complementarity phenomenon is observed in most of the countries (developed and developing) under study.     

风险-收益悖论与绩差基金的业绩持续性

绩差基金的业绩具有持续性,这种现象为何产生,现有文献对此缺乏研究。文章从前景理论和金融市场的异常现象——风险-收益悖论出发,分析绩差基金业绩持续的原因,并提出一种解释这种原因的假说。文章利用我国开放式基金的数据,对这个假说进行了实证检验,检验结果证实：业绩排名落后时基金经理偏好冒险的决策行为,承担高风险却没有得到高收益补偿,是绩差基金业绩持续的重要原因。

The paradox of employee psychological well-being practices: an integrative literature review and new directions for research

Abstract

It is well established that many HR practices aimed at increasing employees’ psychological wellbeing (PWB) and organisational performance conflict and even contradict one another. We address this long-standing issue by undertaking an innovative integrative literature review using the paradox metatheory as a lens. Unlike the contingency approach, a paradox perspective deems real-world tensions as normal, which can also be harnessed, and benefit employees and the organisation. We make three contributions; firstly, we identify contradictory employee PWB and organisational performance HR practices; secondly, we offer a solution in addressing the inherent tension between PWB and organisational performance by developing a new sensemaking conceptual framework; and thirdly, we offer a more nuanced perspective of prevailing arguments by distinguishing endogenous factors that organisations can influence to enhance the synergies between employee PWB and organisational performance HR practices. The intended impact of this paper is to instigate a paradigm shift and shape a new trajectory of thinking about how employee PWB and organisational performance practices can exist side-by-side.     

Ambidextrous leadership,paradox and contingency: evidence from Angola

Abstract

The study departs from two assumptions. First, it considers that organizations, their leaders and the HRM function are inherently paradoxical and that, in that sense, dealing with paradox is a necessary component of the leadership process which requires ambidexterity capabilities. Second, it explores whether the paradoxes of leadership may manifest differently in different contexts. We explore the emergence of paradox in the leadership of Angolan organizations. Angola is an economy transitioning from a centrally planned to a market mode, and this makes it a rich site for understanding the specificities of ambidextrous paradoxical processes in an under-researched, ‘rest of the world’, context. The findings of our inductive study led to the emergence of four interrelated paradoxes and highlight the importance of ambidextrous paradoxical work as a HRM contingency.     

A Synthetic Control Assessment of the Green Paradox: The Role of Climate Action Plans

This paper extends the green paradox literature by providing empirical insights into its existence. To check the green paradox theory, I analyse the production of coal in four major coal‐producing US states that announced a greenhouse gas action plan. To form a statement on whether there is a treatment effect caused by the green policy, I employ Synthetic Control Methods to calculate counterfactual coal production trajectories. I find that Montana experienced a high and statistically significant increase in coal production that is supported by a set of validity indicators. However, there is no evidence for a paradox in Kentucky, Pennsylvania and Virginia.     

中国劳动生产率的“地区—产业收敛悖论”——基于差异分解的实证研究

文献分析和收敛实证检验发现,中国劳动生产率在国家层面上和产业层面上存在相反的结论,可谓之"地区—产业收敛悖论"。运用偏离—份额分析方法将1980—2009年各省份的劳动生产率差异分解成产业结构效应、纯生产率效应和配置效应,并利用统计数据检验每种效应的收敛性。实证结果表明,第一、二产业的纯生产率效应存在绝对收敛,但是产业结构效应和配置效应是发散的。这正是"地区—产业收敛悖论"存在的内在原因,即地区间生产率的收敛并不唯一地由产业的纯生产率决定,还要取决于产业结构效应和配置效应,而这两个效应在中国恰恰是发散的。     

控制权私利下并购成功悖论形成机制研究

并购成功悖论一直困绕着企业并购理论与实务界。本文从控制权私利视角研究了成功悖论形成机制,得到三点结论:一是无论激励为主还是自利为主的控制权私利均有利于控制权人,因而,控制人控制的企业会积极实施并购;二是在自利为主的控制权私利下,并购必然不利于中小股东利益,因而主并方并购绩效为负值;三是以激励为主的控制权私利下,并购并不必然有利于中小股东,提升大小股东共有收益,并保证中小股东得到应有收益份额才有利于改善并购绩效。主并方并购绩效多为零或负值说明制度上重新设计以保障提升共有收益更符合控制权人利益是必要的。     

三元悖论框架下德国经济政策组合研究及启示——以1971—1990年为例

三元悖论理论因为其直观性被当做相关制度选择的标准,在研究了1971—1990年间德国的经验后发现,尽管在三元悖论框架下选择浮动汇率制度和资本开放,获得货币政策的独立性是可行的,但德国中央银行为了经济的良好运行,会有选择性地放弃货币政策的独立性。德国的经验告诉我们,资本账户的开放应该以货币政策的有效性为基础,一国经济政策的选择应该以经济长期稳定均衡发展为依据,单纯以货币政策的独立性作为政策选择的参考标准会有失偏颇。     

On the “merger paradox” in price competition with asymmetric product differentiation

By assuming asymmetric product differentiation, we consider the “merger paradox” in price competition (or the incentive to collude in prices). We investigate whether the emergence of the merger paradox depends on the degree of product differentiation between firms. In particular, unlike Deneckere and Davidson (1985), we demonstrate that if the degree of product differentiation between the insider and outsider is sufficiently small, then they are strategic substitutes, and thus, the merger paradox arises in price competition.
