从国际经济学理论视角看企业竞争优势——兼议国际经济学优势思想的演进

本文通过回顾和分析国际经济学中国际贸易理论和国际直接投资理论优势思想的发展和]进,说明了理论研究可以通过对各种市场结构的细分,把优势分析引入到企业内部,并通过对分工、市场结构与交易费用之间的矛盾关系的深入研究,探讨内生优势与外生优势之间的对立统一关系,而企业竞争优势的培育则是一个建立在企业自身独特能力基础上的、综合利用企业内外部各种比较优势的动态累积发展过程。     

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.     

Learning minimum variance discrete hedging directly from the market

Option hedging is a critical risk management problem in finance. In the Black–Scholes model, it has been recognized that computing a hedging position from the sensitivity of the calibrated model option value function is inadequate in minimizing variance of the option hedge risk, as it fails to capture the model parameter dependence on the underlying price (see e.g. Coleman et al., J. Risk, 2001, 5(6), 63–89; Hull and White, J. Bank. Finance, 2017, 82, 180–190). In this paper, we demonstrate that this issue can exist generally when determining hedging position from the sensitivity of the option function, either calibrated from a parametric model from current option prices or estimated nonparametricaly from historical option prices. Consequently, the sensitivity of the estimated model option function typically does not minimize variance of the hedge risk, even instantaneously. We propose a data-driven approach to directly learn a hedging function from the market data by minimizing variance of the local hedge risk. Using the S&P 500 index daily option data for more than a decade ending in August 2015, we show that the proposed method outperforms the parametric minimum variance hedging method proposed in Hull and White [J. Bank. Finance, 2017, 82, 180–190], as well as minimum variance hedging corrective techniques based on stochastic volatility or local volatility models. Furthermore, we show that the proposed approach achieves significant gain over the implied BS delta hedging for weekly and monthly hedging.     

Incumbency advantage and its value

Markets with network effects are typically concentrated. The aim of this paper is to discuss some recent work on “incumbency advantage.” That is, the fact that firms already installed generate higher profits than entrants even if the latter offer identical or even better terms (in terms of price and quality) to consumers. In particular, we review recently known sources of the advantage and potential mitigating factors and point to a number of open issues.     

Innovation in start-ups: Ideas filling the void or ideas devoid of resources and capabilities?

We investigate how access to different types of resources affects the success of entrepreneurial start-up firms at early stages of development in small isolated economies by studying 12 start-ups based in New Zealand. We find that successful commercialization of innovations depends on the availability of complementary assets, and that capability-based resources, especially dynamic capabilities, have a greater impact on competitive advantage of start-ups than other intangible and tangible assets. For the start-ups in our study, alliances with partners are particularly important, and so the ability to form alliances is a key capability. Successful start-ups leverage their available resources to attract alliance partners in order to access necessary complementary resources. The start-ups in our study clearly demonstrated the ability to attract partners locally but struggled to do so internationally, thereby limiting their growth potential.     

Distributional consequences of political representation

We investigate, both theoretically and empirically, the effect of the geographic concentration of representatives on the geographic distribution of fiscal transfers. Our theoretical model predicts that more representatives residing in a geographic area leads to higher government funds to that area. Our empirical analysis uses the fact that in Germany, due to Germany׳s electoral rules in state elections, the number of representatives varies across electoral districts. Controlling for various socio-economic, demographic, and political variables and using a variety of estimation methods, we find that districts with a greater number of representatives receive more government funds.     

Dynamic capabilities and entrepreneurial management in large organizations: Toward a theory of the (entrepreneurial) firm

Mainstream economic theory has generally excluded consideration of the role of managers, which has, in turn, impaired its ability to explain resource allocation by, and heterogeneity among, firms. In the real world, managers are called on to fill entrepreneurial and leadership roles: sensing opportunities, developing and implementing viable business models, building capabilities, and guiding the organization through transformations. These entrepreneurial management tasks are part of the organization׳s capabilities, which also encompass embedded organizational processes that can be slow to change. An understanding of entrepreneurial management and organizational capabilities will contribute to more realistic economic models and a better understanding by policy makers of industrial dynamics and the requirements of innovation.     

Stakeholder Engagement: Defining Strategic Advantage for Sustainable Construction

Although sustainable development is increasingly becoming a part of business plans, it is unclear what makes the economic, social and environmental dynamics strategically compatible. This research examines which of the following in sustainable development – government policy, managerial attitude and stakeholder engagement – is the most influential on the profitability of companies in the UK construction sector. Quantitative and qualitative analyses were rendered through a survey and semi‐structured interviews. Patterns of ambiguity in legislation were discovered as an obstacle for changing the sector's mind‐set. Stakeholder engagement was identified as the defining factor increasing managers' awareness, helping legislation to be effectively implemented and making sustainability highly appealing to clients. These findings indicate that to gain competitive advantage, companies should embark on long‐term strategic alliances which adopt the proposals of environmental non‐governmental organisations and closely follow public opinion. This, strengthens brand equity, allows for premium pricing, increases market share and maximizes profit. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.
