Intraday return and volatility relationships between the Ibex 35 spot and futures markets

This paper analyses the intraday lead-lag relationships between returns and volatilities in the Ibex 35 spot and futures markets. Using hourly data, we jointly analyze the interactions between markets, estimating a bivariate error correction model with GARCH perturbations which captures stochastically the presence of an intraday U-shaped curve for both spot and futures market volatility. Our findings show a bidirectional causal relationship between market volatilities, with a positive feedback. This two-way transmission of volatility is consistent with market prices evolving according to a long-run equilibrium relationship, and shocks affecting both markets in the same direction. Our empirical results also support a unidirectional cross interaction from futures to spot market returns. This pattern suggests that the futures market leads the spot market in order to incorporate the arrival of new information.     

Worker Turnover, Job Turnover and Collective Bargaining in Spain

This paper analyses the relationship between the presence of organized labour in firms (approximated by the scope of collective bargaining) and the extent of gross worker and job flows. According to the voice theory of Freeman, those firms having a union presence will have lower worker mobility. However, there is no analysis of the effects of the presence of organized labour on gross job flows. Using a Spanish data base, we find evidence of the existence of a voice effect on gross worker flows but not clear support for a voice effect on gross job flows.     

Feature selection methods involving support vector machines for prediction of insolvency in non‐life insurance companies

We propose two novel approaches for feature selection and ranking tasks based on simulated annealing (SA) and Walsh analysis, which use a support vector machine as an underlying classifier. These approaches are inspired by one of the key problems in the insurance sector: predicting the insolvency of a non‐life insurance company. This prediction is based on accounting ratios, which measure the health of the companies. The approaches proposed provide a set of ratios (the SA approach) and a ranking of the ratios (the Walsh analysis ranking) that would allow a decision about the financial state of each company studied. The proposed feature selection methods are applied to the prediction the insolvency of several Spanish non‐life insurance companies, yielding state‐of‐the‐art results in the tests performed.

Partial Horizontal Inequity Orderings: A Non‐parametric Approach*

We provide a partial ordering view of horizontal inequity (HI), based on the Lorenz criterion, associated with different post‐tax income distributions and a (bistochastic) non‐parametric estimated benchmark distribution. As a consequence, several measures consistent with the Lorenz criterion can be rationalized. In addition, we establish the so‐called HI transfer principle, which imposes a normative minimum requirement that any HI measure must satisfy. Our proposed HI ordering is consistent with this principle. Moreover, we adopt a cardinal view to decompose the total effect of a tax system into a welfare gain caused by HI‐free income redistribution and a welfare loss caused by HI, without any additive decomposable restriction on the indices. Hence, more robust tests can be applied. Other decompositions in the literature are seen as particular cases.

高技术企业知识体系概念框架及其内部互动模型——一个解释知识创新过程的新框架

企业知识是组织内部个人知识的集合体 ,但不是个人知识的简单加总。基于这个认识 ,本文构建了一个由知识员工、知识链和知识场构成的点、线、面互动的企业知识体系研究框架。高技术企业是追求持续知识创新的知识体系 ,知识创新通过知识点之间的互动完成 ,如同电荷之间的运动通过电场来进行 ,知识点通过知识场发生相互作用。本文提出了知识场的概念 ,分析了其与Nonaka的“巴”的区别与联系 ,并对其进行了分类。进一步的 ,根据高技术企业知识体系运行的基本路径 ,文章分别研究了体系内知识点通过知识场进行互动的基本模式与作用机制。文章试图提出一个能够解释知识创新过程的新框架。
