'An awkward fence to cross': railway capitalization in Britain in the inter-war years

This paper examines the related problems of the capitalization and financial performance of the railway companies in the inter-war period. It examines the critics' view that the railways were over-capitalized, and places the debate in context by analysing the dividend and accounting policies of the companies and the consequences for investment. It also examines the conflicting views of railway management and shareholders over capital expenditure. The paper concludes that the railways were both financially over-capitalized and physically under-capitalized, and so faced very serious financial problems that were incapable of resolution within the existing ownership structure.

盈利要求与投资决策

本讨论了公司盈利要求对经理投资决策行为的影响，并进一步将该结果与社会最优结果进行了比较分析。本研究结果表明，较高的盈利要求将导致经理选择高风险的投资项目，即使该投资项目的预期收益未必高于低风险投资项目。从社会福利最优角度来看，盈利要求对社会福利的影响取决于公司所面临的投资环境和投资项目性质。

中国经济真的动态无效吗

史永东与杜两省、史永东与齐鹰飞、袁志刚与何樟勇相继考察了中国经济的动态效率,结果均表明中国经济是动态无效的.本文首先通过实证研究进一步检验上述结论,并进而追问中国经济为什么会发生动态无效.笔者的分析表明,这种无效性只是一种表象,它是由我国的粗放式经济增长方式决定的,其根源在于静态资源配置,特别是投资配置的无效性.在此基础上,本文进而指出,上述作者提出的消除无效性的政策建议是不恰当的,真正有效的途径只有转变增长方式,提高增长绩效.     

Integrating corporate ownership and pension fund structures: A general equilibrium approach

This paper studies pension fund design in the context of investment in the debt and equity of a firm. We employ a general equilibrium framework to demonstrate that: (i) the asset location ‘puzzle’ is purely a partial equilibrium phenomenon, conceived in a risk neutral setting, that disappears with the introduction of sufficient risk aversion; (ii) the inability of policy makers to manage an economy with multiple firms yields a mixed equilibrium, where bonds are observed in both taxable and tax-deferred accounts; and (iii) the Pareto-efficient pension plan comprises of a defined benefit plan.     

外资进入和我国企业的生产率：“溢出”抑或“挤出”效应

我国改革和开放是同时推进的，引进了众多外资企业来推动我国经济发展。那么，外资企业的进入是否有助于我国内资企业的成长？本文分析我国工业企业超大样本数据，探讨外资进入的影响，研究我国内资企业的生产率能否向效率前沿收敛。结果发现，我国不同类型的内资企业均存在效率前沿的收敛趋势，内外资企业生产率差距不断缩小。外资进入对我国内资企业的短期影响主要表现为溢出效应，但是对于同行业的其他外资企业呈现挤出效应，特别是其他独资外企。我们进一步发现外资进入的长期影响是挤出效应，但是对于国有企业和民营企业的影响却不尽相同。     

The impact of equity ownership groups on investment: Evidence from Ukraine

We empirically investigate the impact of different ownership groups on companies’ investment in Ukraine with a novel dynamic investment model where investment is based on present and historical levels of profitability (market-to-book value of equity) and lagged investment. Groups include state, insider, non-domestic, financial and financial and industrial group (FIG) ownership. Contrary to the literature, we find that the past level of profitability significantly affects investment; the majority presence of and increases in state ownership have a negative impact on firms’ investment, as is the case for non-domestic and financial companies’ ownership. Insider and FIG ownership have no impact on investment. We explain the results by the extent of liquidity concerns (hard and soft budget constraints), measured by cash flow interacted with a dummy variable of majority ownership of the respective group, and the extent of asset stripping for the corresponding ownership group and relate them to over- and under-investment, and to the free cash flow or cash constraint hypothesis.     

Stage-gate process for life sciences and medical innovation investment

Life science innovation has led to significant improvements in clinical outcomes and has been a source of financial growth for individuals and institutions capable of performing appropriate investments in this sector. Several groups have developed methodologies to assist medical technology innovators in the design and development activities. Unfortunately, these tools have not aided the general investment community to profit from these enterprises. This situation has contributed to a general reduction in risk capital directed towards life sciences compared to other industries. We review the current investment practices in the life science sector and present a comprehensive stage-gate model that aims to captures this investment process. An analysis of best practices and in-depth interviews with 68 life sciences investors and entrepreneurs worldwide are used to support such model. A single case-control study comparing life science investment execution within two similar investment firms was conducted to evaluate feasibility in the implementation of these practices. The stage-gate model includes (I) General vision and investment strategy definition; (II) Venture search, screening and rapid pre-evaluation; (III) Due diligence and negotiation of terms; (IV) Portfolio management, evaluation, and exit. The difference in execution of investment and results from a post-performance Root Cause Analysis were consistent with a reduction in perceived risk from the case company trained with the proposed model compared to the control. This suggests that our developed model and process may be useful in encouraging life sciences investment via evidence-based evaluations.
