外来者劣势与海外并购企业的生产率提升

海外并购已成为新兴经济体企业对外投资和实现国际化扩张的重要战略选择。外来者劣势是中国企业海外并购活动面临着的诸多困难之一。“外来者”身份会对企业并购后的整合与生产率提升这一关键问题产生负面影响,化解负面影响需作深入的细化研究。选取2008-2015年中国上市企业共计197起海外并购事件,以制度距离、文化距离以及地理距离分别作为外来者劣势中合法性缺失和信息不对称的替代变量,分析外来者劣势对海外并购企业生产率提升的作用机制。结果显示,合法性缺失导致的外来者劣势对海外并购企业的生产率提升有显著负影响,但信息不对称对生产率的影响并不显著。调节效应检验结果表明,国内投资能显著弱化制度距离和文化距离引致的外来者劣势对海外并购企业生产率的负影响,国际化经验和出口能克服制度距离带来的合法性问题,但对文化距离带来的合法性缺失的弱化效果并不明显。     

产业链的合作机制选择与低碳产品定价及碳减排策略

生产链上下游企业选择合适的合作机制对低碳产品定价及碳减排有重要影响。通过构建博弈模型分析三种不同合作机制下的低碳产品定价及碳减排问题:第一种合作机制即制造商与零售商进行合作,当两条生产链都选择这种合作机制时,能带来较高的碳减排率和较低的零售价格,这对制造商、零售商、消费者和环境都是有利的。第二种合作机制即两条生产链的制造商之间、零售商之间分别合作,这会带来较低的碳减排率和较高的零售价格,对两个制造商有利,而对零售商和消费者不利。分析前两种合作机制的利与弊提出第三种合作机制,即零售商和制造商共享利润下的有利于碳减排的策略。最后,结合案例讨论和数值分析的研究结果表明:当制造商和零售商收入共享比在一定范围内时,第三种合作机制可以给制造商和零售商带来更高的利润。由此为企业选择最佳的合作机制及合理的碳减排策略提供了理论指导。     

Profitability and Efficiency of High Nature Value Marginal Farming in England

The UK Brexit vote triggered a new wave of policy developments for a future outside the EU. In this context, we analyse the business performance of English hill and upland farms, characterised by marginal economic conditions but also high nature value (HNV). The analysis aims to help identify farm-level management and policy options for greater economic, environmental and social sustainability. Business performance is measured as technical efficiency and the occurrence and persistence of abnormal profits, estimated through stochastic frontier analysis and static and dynamic panel-data methods. The results help indicate rationales for recent trends including farm enlargement, farm family diversification, and agri-environment scheme entry. The single farm payment is found to be negatively associated with farm technical efficiency while agri-environmental subsidies were positively associated to short-term farm profitability. Farm adaptation and resilience during a period of likely turbulence in external circumstances is discussed in light of these findings, as well as potential parallels with marginal HNV areas across Europe.     

Competition in the stock market with asymmetric information

We build a game theoretical model to examine how the level of information advantage of insiders and the competition between insiders and sophisticated investors affect stock price movements and traders’ trading strategies and profits. We show that the competition between insiders and sophisticated investors can reduce the losses of less sophisticated investors, and thus alleviates the disadvantaged position of the less sophisticated investors. Further, traders’ profits are affected by the accuracy of insiders’ private information, and the number of days that insiders have obtained the information in advance. These findings show the importance of information transparency and the role of sophisticated investors in limiting insiders’ trading advantages and mitigating the expropriation of investors by insiders.     

How to measure competition in an economy in transition

This paper attempts to find a robust method of measuring competition when firms' operational activities are subject to frictions. The first part theoretically tests the indicative quality of two competition measures, the price‐cost margin (PCM) and the profit elasticity, in a model of monopolistic competition. The second part studies the empirical performance of the indices for a panel of Ukrainian manufacturing firms. This study offers a new approach to measuring profit elasticity that relies on structural estimation of a production function. The estimation methodology retrieves a productivity index that is adjusted to imperfect competition. The proposed method of measuring profit elasticity is found to be robust to frictions, but the PCM and traditional profit elasticity are biased, especially when the intensity of competition is low. Empirical findings show that competition exhibits a significantly positive correlation with aggregate productivity performance, while its impact on firm productivity is nonlinear.     

The Labor-Managed Firm: Permanent or Start-Up Subsidies?

We explore a new argument that seeks to explain the near absence of the labor-managed firm or cooperative, despite a range of inefficiencies attributed to the present-day capitalist firm. We derive the crucial condition for the emergence of labor-managed firms and show that it is unduly restrictive from an efficiency point of view. The policy implication is that public intervention to promote labor-managed firms should primarily be in the form of start-up subsidies rather than in providing permanent tax subsidies.

The Greek economic crisis: causes and alternative policies

The Greek economic crisis is primarily structural and the result of an international economic impasse that developed in 2007, with devastating implications for the struggling peripheral economies of Europe. This article suggests that falling profitability led to the stagnation of profits, which in turn discouraged new investment, decreased production and increased unemployment. The resulting recessionary economic environment, in conjunction with the mounting public debt and the austerity policies imposed on the Greek economy by the so-called ‘troika’ of creditors in 2010, has decimated the Greek economy even further, causing one of the worst economic crises since the Second World War. The article also provides some broad guidelines for an alternative economic policy.

A Micro-Approach for Testing Marx's LTRPF: Evidence from Greece, 2000 and 2009

This article develops a novel micro-approach for the empirical evaluation of Marx's law of the tendency of the rate of profit to fall. Contrary to the traditional method which uses national macroeconomic data, this approach utilises data taken directly from company reports and accounts. The principal advantage of this approach is that it provides an accurate measurement of the value composition of capital, devoid of the measurement limitations of the traditional method regarding variable capital which stem from the inability to distinguish productive from unproductive labour. A disadvantage, however, is that this approach does not cover the entire national economy. The application of the proposed micro-approach to the ongoing Greek crisis yields results which are congruent with the traditional method and reinforce other recent studies linking the current crisis with low profitability.
