Defence contractors and diversification into the civil sector: Rolls-Royce, 1945–2005

A number of studies have shown that defence contractors have exhibited a marked reluctance to diversify away from defence and develop civil applications. However, the aero engine manufacturer Rolls-Royce is one defence contractor to which this does not apply. Over a 60-year period it has moved from being almost entirely dependent on defence work to a point where defence now constitutes barely one-fifth of its turnover. This article examines the development of the company's civil aerospace business over the period since 1945. It focuses specifically on the strategies used by Rolls-Royce in the civil aerospace field. These strategies are explored in the context of changes in market conditions, technology, and governance arrangements. The effectiveness of the various strategies, including their contribution to the company's current position, is evaluated.

Bank capital regulation, diversification loss and the probability of bank failure

This paper investigates the effect of bank capital regulation on the probability of bank failure. Utilizing a two-parameter approach, it is shown that the relationship between bank capital ratio and probability of bank failure is not necessarily negative, and that capital ratio regulation may increase the probability of bank failure. This is because an increase in bank capital ratio may lead to diversification loss via a decrease in the number of borrowers to which a bank offers loans.     

“Effectively organic”: Environmental gains on conventional farms through the market?

Qualitative field research in England identified a cohort of farmers practicing what they self-defined as ‘effectively organic’ or ‘semi-organic’ farming. Utilising Ajzen's theory of planned behaviour as a framework for analysis, reducing inputs was found to be primarily a response to financial pressures, also reflected in changing substantive norms towards balancing risks and potential returns against investment, rather than optimising production. However, despite the apparent ease of converting to organic farming from low input practice, formal conversion to organic farming was not found to be the automatic outcome of this trajectory: instead, organic farming was identified as only one of a number of options for increasing the financial viability of the farming operation, which included other niche markets, pluriactivity and contracting land to and from other farmers. The affiliation of low input farmers with organic production denotes positive attitudes towards both organic farming and environmental practices, but a lack of understanding about organic farming techniques. The author argues that due to declining returns/input ratios, future conversion to organic farming may reflect the value placed on other aspects of organic production, such as increased labour, risk reduction and environmental ideals, and highlights the environmental implications of the ongoing ‘cost price squeeze’ on farming households.     

Rao’s quadratic entropy and maximum diversification indexation

This paper proposes a new formulation of the maximum diversification indexation strategy based on Rao’s Quadratic Entropy. It clarifies the investment problem underlying this diversification strategy, identifies the source of its out-of-sample performance, and suggests new dimensions along which this performance can be improved. We show that these potential improvements are quantitatively important and are robust to portfolio turnover, portfolio risk, estimation window, and covariance matrix estimation.     

公司多元化战略对资本结构影响的研究——基于面板数据的实证分析

从战略管理和财务理论融合的角度,利用762家上市公司的面板数据对公司多元化战略与资本结构之间的关系进行实证分析,研究发现:公司的债务水平与多元化程度存在显著的正相关关系,并且单一业务型公司的负债水平最低,主导业务型和相关业务型公司的居中,非相关业务型公司的债务水平最高.因此,公司战略的制定与实施应考虑其财务影响;同样,资本结构决策也应该考虑如何与公司战略相配合,以从资本结构决策中获得竞争优势.     

中国艺术品投资收益:离岸与在岸市场的特征和互动

文物艺术品既是一个国家的历史印记和文化瑰宝,也是情感资产和动产。本文基于2000-2017年全球艺术品核心市场--北京、香港、纽约和伦敦核心拍卖行中国书画的微观数据,使用特征价格法构建全球中国艺术品市场价格指数,展示全球中国艺术品拍卖市场发展的全貌,同时创新性地使用重复交易数据探讨离岸和在岸中国艺术品市场投资特征和互动关系。研究表明:北京和香港市场作为中国艺术品最大的在岸和离岸拍卖市场价格相互联动,走势基本一致;艺术品财务收益和精神回报是艺术品投资收藏和消费的主要原因,不同市场间财务收益和风险分散的差异是艺术品市场资产配置和资金流动的动力;纽约和伦敦市场中国艺术品投资收益率低于北京和香港,香港是全球中国艺术品投资收益率最高的地区,重复交易中的北京-香港交易策略占优,离岸香港市场得天独厚的环境优势使香港中国艺术品市场未来发展前景可期。     

中国特色先进国防科技工业体系内涵与实现路径

中国特色先进国防科技工业体系是由“国防科技研发—武器装备生产—制度环境”三大核心要素相互耦合而成的共生系统。党的领导是中国特色先进国防科技工业的“特色”之处,“先进性”体现在国防科技工业体系开放程度高、运行高效、布局合理、结构优化等方面,并且具有军民融合、创新驱动、绿色环保、动态调整的特点。构建中国特色先进国防科技工业体系,要从现有国防科技工业体系与目标体系的差距入手,综合运用市场和政府两种手段,针对市场准入、产业结构和布局调整、军工企业改革、鼓励创新与军民融合等方面进行综合设计。     

中间品进口多样化、企业创新与工资水平

基于2000-2006年中国制造业企业数据库以及进出口海关数据库的匹配数据引入企业创新机制效应检验中间品进口多样化的工资溢出效应。研究表明中间品进口多样化、企业创新均能显著提高企业的工资水平。进一步考察企业的出口状态、所有制结构及企业所属地区差异后发现中间品进口多样化对出口企业、外资企业以及东部地区企业的工资影响更为显著。分位数回归结果进一步显示中间品进口多样化及企业创新对工资分布高分位企业的工资影响更为显著。基于中介效应模型的传导机制检验,认为中间品进口多样化通过节约成本、提升生产率及企业创新影响中国制造业企业工资水平的利润共享机制存在。在控制成本效应及生产率效应两种机制之后,企业创新成为中间品进口多样化作用于企业工资的新机制。
