Good to be home? Time‐use and satisfaction levels among home‐based teleworkers

Home‐based teleworking (HbTW) has the potential to provide significant benefits to both employer and employee, but also presents considerable challenges. This paper considers HbTW among UK employees, specifically exploring distinctions in the time‐use of men and women home‐based teleworkers and the impacts of HbTW on employee satisfaction levels, using cross‐section fixed effects panel regression analysis of the British Household Panel Survey. Findings reveal that total time‐use in work activities among men and women home‐based teleworkers is relatively comparable, but the distribution significantly different. For women, housework represents a particular time constraint, reflecting continued presence of the ‘double‐shift’. Homeworkers report greater levels of satisfaction, yet they are more pronounced in respect to paid work than leisure time. Extensive hours of housework reported among women may explain these differences. Nevertheless, home‐based teleworkers report greater levels of satisfaction than other workers, suggesting considerable benefits especially for working mothers.     

Record values from generalized Pareto distribution and associated inference

In this paper, we derive exact explicit expressions for the single, double, triple and quadruple moments of the upper record values from a generalized Pareto distribution. We then use these expressions to compute the mean, variance, and the coefficients of skewness and kurtosis of certain linear functions of record values. Finally, we develop approximate confidence intervals for the location and scale parameters of the generalized Pareto distribution using the Edgeworth approximation and compare them with the intervals constructed through Monte Carlo simulations.

中国消费者短视行为的理论与实证研究

借用并修改金蛋模型，以拟双曲形贴现效用函数和预算约束中的短期储蓄目标，刻画了中国消费者的短视行为。得出了中国消费者会在短视期内消费尽扣除短期储蓄目标外的所有资产，并根据当期收入水平和短期储蓄目标平滑消费的结论。通过实证检验，论证了我国消费者短视消费行为的存在，并大致确定了短视期的平均长度。

Double Lookbacks

A new class of options, double lookbacks , where the payoffs depend on the maximum and/or minimum prices of one or two traded assets is introduced and analyzed. This class of double lookbacks includes calls and puts with the underlying being the difference between the maximum and minimum prices of one asset over a certain period, and calls or puts with the underlying being the difference between the maximum prices of two correlated assets over a certain period. Analytical expressions of the joint probability distribution of the maximum and minimum values of two correlated geometric Brownian motions are derived and used in the valuation of double lookbacks. Numerical results are shown, and prices of double lookbacks are compared to those of standard lookbacks on a single asset.     

非对称信息条件下银企信贷问题的双信号博弈分析

通过研究在信息非对称条件下企业和银行的信贷问题,建立风险率、资产负债率的双信号传递博弈模型,可以得出企业风险率、资产负债率的临界值.银行可通过对企业发出的风险率以及资产负债率与其临界值的比较进行推测,从而判断是否对企业进行贷款.     

我国税收抵免制度的完善

我国现在主要采用直接抵免法，不允许采用间接抵免方法。应在国内税法中制定相应条款，明确规定税收抵免的主体和对象，完善对外税收协定。现阶段我国对外投资主要是流向了避税港，应制定避税港有关税收制度，防止纳税人国际避税。对境外盈亏应不允许互抵，实行分国不分项弥补是较可取的选择。     

高职计算机专业“双师型”教师队伍的建设

高职计算机专业教师队伍的学历结构、职称结构、知识结构等不合理。加强“双师型”高职计算机专业教师队伍的建设一方面要加强引进,一方面要加强培养,走产学研相结合的道路,注重理论的提升和技能的深化。
