刍议完善我国粮食安全预警机制的三个核心问题

我国的粮食安全预警机制的完善涉及到三个核心问题。一是有关粮食安全预警的组织机构问题。缺乏一个权责明确的预警机构,粮食安全预警机制作用就难以发挥。二是有关粮食安全预警的信息采集问题。粮食安全的信息量十分巨大,其撷取的方法是否精准及衡量粮食安全的指标体系的选择是否得当,直接关系到粮食安全预警的效用与价值。三是如何将粮食安全预警的信息传递给有关职能部门的问题,这需要构建一套规范的运作程序。     

激励在医院人力资源管理中的应用

激励是人力资源的重要内容。激励体系应用于医院人力资源管理之中,就是要激发医务工作者的工作动机,使他们的积极性和创造性继续保持和发扬。因此能否建立起科学有效的激励体系,将影响到医院的长远发展。本文介绍了激励及激励体系的基本内涵,指出了现有医院激励体系存在的问题,对医院激励体系的设计和优化进行了探讨。同时提出了医院激励体系在设计和优化过程中应注意的几个问题。     

我国入境旅游者流动行为机理分析——对旅游热点城市西安的实证研究

旅游者流动机理是旅游地理学与旅游者行为学交叉研究的重要内容。推—拉理论是解释游客流动原因的一种有效方法。以西安入境旅游者为研究对象,从推—拉理论的视角,运用因子分析、单因素方差分析和皮尔逊相关分析等方法对来华入境游客的流动机理进行研究,得到的主要结论有:①明确了西安入境旅游者推力维度和拉力维度的各个因子;②检测了推拉维度的各因子受社会人口统计学变量的影响;③测度了推拉维度各因子之间的相互关联性及影响因素。研究成果对指导我国各主要旅游城市进行针对性的产品开发和市场营销具有一定的实践价值,同时在理论上也拓展了国内旅游流推力与拉力之间关系研究的范畴。

Managers’ Escalation Behavior in Equity Investment Decisions and the Role of Corporate Governance

The aim of this study is to investigate the relationship between free cash flows and escalation behavior in the long-term stock buying decisions for the firms listed in Taiwan. The main findings include: (1) Managers tend to exhibit the escalation behavior in the long-term equity investment. (2) There is a positive association between the level of free cash flows and the magnitude of managers’ behavioral escalation. (3) The corporate governance mechanisms play a contributory role in mitigating the escalation behavior. The evidence is robust across subsamples for electronic versus non-electronic industries, growth versus value firms, and loss versus gain firms.     

What constrains firms from divesting their legacy business?

This study focuses on a unique business phenomenon, legacy divestitures, which refers to the sale or spinoff of a firm's original business. I argue that firms may be prevented from engaging in legacy divestiture by organizational inertia, which become increasingly stronger as the legacy business gets older. I also examine factors that help firms overcome the constraints of inertial forces on firms' legacy divestitures. Hypotheses are tested using a sample of 108 diversified American companies, 27 of which divested legacy businesses between 1980 and 2017. Firms are less likely to divest their legacy businesses as the legacy units get older. The negative relationship is weakened by two factors, performance–aspiration gaps and R&D intensity.     

Pricing risky corporate bonds: An empirical study

This paper empirically studies a model for pricing risky corporate bonds proposed by Baaquie—based on the seminal Merton. The proposed model provides an exact solution for the price of a risky corporate bond with a finite maturity and explains the market price of corporate fixed coupon bonds as being the result of the market risk that is carried by the bond. Baaquie's model is empirically tested using 42 fixed coupon bonds issued by 23 US corporations, between 2011 and 2017. It is found that the proposed model estimates most bond prices quite accurately. Market time (similar to the concept of psychological time), which is distinct from calendar time, is quantified in the paper and is an exogenous behavioral parameter that plays a pivotal role in improving the accuracy of the pricing model for long-maturity risky bonds.     

Media visibility and corporate social responsibility investment evidence in Spain

Despite the extensive research in both the determinants and the results of corporate social responsibility (CSR), relatively few studies have considered extra-legal institutions as potential determinants of CSR. Our work fills this gap by looking at how media attention affects CSR over a long-term period in a continental European setting. Our results show that media coverage positively affects CSR. Additional scrutiny triggered by media coverage encourages dominant owners to signal their commitment to limiting self-dealing transactions and their orientation toward stakeholders' needs through CSR investments. Additionally, our results reveal that this signaling device offers greater benefits and lower costs in firms where controlling owners show a voting-cash flow wedge. Our results are relevant to different actors such as investors, auditors, and policy makers as they provide solid evidence that media coverage is an important driver of CSR orientation in a continental European setting.
