Building internal business scenarios based on real data from a performance measurement system

This paper presents a new methodology to build internal business scenarios from the data gathered by some key performance indicators (KPIs) defined within a performance measurement system. The application of the principal components analysis technique leads to the identification of latent relationships between KPIs that underlies some important business aspects. Further, this methodology allows to represent not only the temporal evolution of the organisation as a function of these business aspects but also the definition and determination of internal business scenarios, being therefore the source of meaningful managerial information. At the end of the paper, results of a practical application are presented and discussed, as well as their importance for the organisation from a decision making point of view.

A note on how to measure hubbing practices in airline networks

Benefits and costs associated to hubbing practices of airlines are still subject to much debate. In the previous literature, some standard spatial concentration indices have been proposed to measure it. However, we show that these indices are “ill-defined” because they do not take into account the salient characteristic of hubbing: connecting passengers. The purpose of this research is to present a new methodology which avoids the pitfalls of other methods. Our new methodology also analyzes the level of concentration of the connecting passengers studying two different dimensions: hub airports and routes. Finally, we apply our methodology to some US carriers.     

Testing prospect theory in airline demand

The article tests for the existence of reference dependence, loss aversion and diminishing sensitivity in airline demand, in the context of price responsiveness amongst low cost, regular and charter airlines. We incorporate the reference-dependent model into a mixed model to control for heterogeneity. The application finds considerable differences between reference and actual prices in decision-making, confirming that reference dependence exists. People react more strongly to price increases than to decreases relative to their reference price supporting the loss aversion phenomenon and that there is diminishing sensitivity for losses only.

Is the January effect still alive in the futures markets?

The January effect concerns the fact that small capitalization stocks have historically outperformed large capitalized stocks in January. We analyze evidence as to whether this anomaly can be exploited in the futures markets as a speculative investment or to add risk-adjusted value to portfolio performance. We find that the January effect is still alive in the futures markets on the Value Line minus S&P 500 spread trade, but that the marginal liquidity of the Value Line stock index futures contract has made it very risky to exploit the effect. Historically from 1982/3 to 2004/5, the trade has been profitable. This anomaly was also exploitable through a Russell 2000 minus S&P 500 spread trade from 1993/4 to 2004/5.

网络环境下经济行为边界的确定

现代社会是信息社会,互联网和计算机应用是最明显的特征。人们基于网络参与经济决策与市场交易活动,道德理念、行为准则和行为安排发生了较大的变化。网络技术:一方面,极大地降低了交易费用;另一方面,由于经济行为的隐蔽性,追求经济利益的行为缺乏有效监督,人的趋利避害和机会主义倾向更容易诱发蓄意性诱导行为。在网络环境下,如何界定“经济人”的行为模式,怎样减少经济行为负的外部效应成为经济学理论研究的问题。本文主要讨论网络环境中“经济人”经济行为边界的确定。

人才政策可以促进企业全要素生产率增长吗*——基于地方政府人才治理视角的研究

本文使用2001—2016年我国国家法律法规数据库中针对人才出台的地方性法规及部门规章对人才政策予以定量识别,并与上市企业数据进行匹配,实证检验了地方人才政策对企业全要素生产率的影响。研究发现,人才政策能够显著促进企业全要素生产率增长。具体而言,人才政策出台数量平均每增加1条,能够促进企业全要素生产率增长约0005。机制检验证明,人才政策通过提高企业技术创新水平和纠正人力资本在企业间的错配两条路径促进企业全要素生产率增长。此外,企业及行业异质性研究发现,人才政策对非国有企业及高技术产业全要素生产率的影响大于国有企业及非高技术产业。以上发现对于当前地方政府人才治理体系建设具有较大意义,对如何完善政府人才政策促进中国经济高质量发展也具有一定启示。
