Regulation and investment behaviour in the telecommunications sector: policies and patterns in US and Europe

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings.

Calibrating an algorithm for estimating transactions from FXFX exchange rate quotes

In this paper we investigate the efficiency of a class of transaction-generating algorithms, originally suggested in Bollerslev and Domowitz (1993). Our comparison utilizes real transaction data recorded over Reuters D2000-2 electronic broking system for 7 h in June 1993 and transaction data generated from FXFX quotations over an identical period. Results suggest that, at this high-frequency data sampling, the performance of these transaction-generating algorithms is poor, with the most likely explanation of this outcome due to the high-frequency characteristics of FXFX spreads and quotation intensity.     

Valuation of vulnerable American options with correlated credit risk

This article evaluates vulnerable American options based on the two-point Geske and Johnson method. In accordance with the Martingale approach, we provide analytical pricing formulas for European and multi-exercisable options under risk-neutral measures. Employing Richardson’s extrapolation gets the values of vulnerable American options. To demonstrate the accuracy of our proposed method, we use numerical examples to compare the values of vulnerable American options from our proposed method with the benchmark values from the least-square Monte Carlo simulation method. We also perform sensitivity analyses for vulnerable American options and show how the prices of vulnerable American options vary with the correlation between the underlying assets and the option writer’s assets.      

关于无形资产评估中折现率确定方法的探讨

折现率的预测和确定是无形资产评估中的难点问题之一。由于折现率是影响评估结果准确度的重要参数,所以在当前对高质量资产评估结果的需求日益迫切的背景下,有必要再度探讨无形资产折现率确定方法的相关问题。本文提出应根据引起无形资产评估的具体情况来选择合理的折现率确定方法;同时也提出了无形资产折现率确定方法运用和发展的几点建议:科学性和合理性相结合、静态分析与动态分析相结合、因素分析与模型分析相结合。     

Can employee ownership and human resource management policies clash in worker cooperatives? Lessons from a defunct cooperative

The article analyzes the interaction between employee ownership, HRM policies and practices, and HRM outcomes in what was the world's biggest industrial worker cooperative for decades, and now defunct, Fagor Electrodomésticos. Using longitudinal internal data and detailed interviews with key stakeholders, this paper sheds light on how employee ownership conditioned HRM policies. HRM outcomes—such as job satisfaction and absenteeism—are also analyzed over a long period of time. Chronic nepotism when recruiting new members, failures in the training policy, impoverished and Taylorist working systems, and reverse dominance hierarchies are analyzed as factors that increased free riding and caused low satisfaction and the disengagement of working members. This case study contributes to the literature on HRM and worker cooperatives as it provides some insights that are rarely found in that literature. It also provides guidance to worker cooperatives about increasing the fit between employee ownership and HRM policies and outcomes.     

基于决策树的土地利用覆盖分类及变化研究——以济宁市任城区为例

以济宁市任城区为研究对象,获取研究区域2001年、2006年和2011年三期Landsat ETM与TM影像,通过ENVI遥感影像处理软件分析了研究区影像的光谱特征以及植被归一化指数（NDVI）、建筑归一化指数（NDBI）以及水体归一化指数（NDWI）,利用决策树算法确定各地类的综合阈值,建立决策树模型,得到了土地利用覆盖分类结果并取得了良好的分类精度。同时通过对研究区2001至2011年的土地利用动态度及土地利用转移矩阵的分析得出研究区在研究期内的土地利用覆盖变化特征,最终得出结论：（1）利用决策树分类能够获得较高的分类精度;（2）任城区城镇化发展迅速,城镇化在区域土地利用覆盖变化过程中起到了主导性的作用。
