Holistic trajectories: a study of combined employment, housing and family careers by using multiple-sequence analysis

Summary.  Social science applications of sequence analysis have thus far involved the development of a typology on the basis of an analysis of one or two variables which have had a relatively low number of different states. There is a yet unexplored potential for sequence analysis to be applied to a greater number of variables and thereby a much larger state space. The development of a typology of employment experiences, for example, without reference to data on changes in housing, marital and family status is arguably inadequate. The paper demonstrates the use of sequence analysis in the examination of multivariable combinations of status as they change over time and shows that this method can provide insights that are difficult to achieve through other analytic methods. The data that are examined here provide support to intuitive understandings of clusters of common experiences which are both life course specific and related to socio-economic factors. Housing tenure is found to be of key importance in understanding the holistic trajectories that are examined. This suggests that life course trajectories are sharply differentiated by experience of social housing.     

FDI的工资效应研究——基于江苏省制造业面板数据的分析

利用江苏省制造业2000--2006年的面板数据，从行业角度分析FDI对于江苏省制造业平均工资以及国有企业工资的影响，结果表明外资企业的进入可以通过提高整体的劳动生产率水平从而间接提高整体平均工资水平；劳动力工资与加工贸易的开放程度之间呈正相关关系，而与行业规模大小呈负相关．外资对于国有企业劳动力工资存在正的工资溢出，但是国内资本对于劳动力工资水平的影响与外商直接投资相比相差不大，甚至可以超过外商直接投资的贡献。

On calculating the fisher information in order statistics

This article gives a simple result for the expression of the Fisher information in order statistics. This result enables us to calculate easily the Fisher information in any set of order statistics whose details have been known to be messy and complicated. We consider here its application in the optimal spacing problem where the exact Fisher information in order statistics has been approximated with the asymptotic information or the reciprocal of the variance of a suitable estimator.

Sampling Returns for Realized Variance Calculations: Tick Time or Transaction Time?

This article introduces a new model for transaction prices in the presence of market microstructure noise in order to study the properties of the price process on two different time scales, namely, transaction time where prices are sampled with every transaction and tick time where prices are sampled with every price change. Both sampling schemes have been used in the literature on realized variance, but a formal investigation into their properties has been lacking. Our empirical and theoretical results indicate that the return dynamics in transaction time are very different from those in tick time and the choice of sampling scheme can therefore have an important impact on the properties of realized variance. For RV we find that tick time sampling is superior to transaction time sampling in terms of mean-squared-error, especially when the level of noise, number of ticks, or the arrival frequency of efficient price moves is low. Importantly, we show that while the microstructure noise may appear close to IID in transaction time, in tick time it is highly dependent. As a result, bias correction procedures that rely on the noise being independent, can fail in tick time and are better implemented in transaction time.     

A regression-based smoothing spline Monte Carlo algorithm for pricing American options in discrete time

American options in discrete time can be priced by solving optimal stopping problems. This can be done by computing so-called continuation values, which we represent as regression functions defined recursively by using the continuation values of the next time step. We use Monte Carlo to generate data, and then we apply smoothing spline regression estimates to estimate the continuation values from these data. All parameters of the estimate are chosen data dependent. We present results concerning consistency and the estimates’ rate of convergence.     

FDI、要素成本与东道国产业发展

论题拓展了James R Markusen（1997）的基本模型，重点纳入外商直接投资进入东道国对其要素市场的影响，分析了FDI与东道国产业的关联效应以及在要素市场的竞争效应对东道国产业发展的影响。外商直接投资将通过关联效应和要素市场的竞争对东道国产业发展产生一个动态二阶段影响过程：在初始阶段外商直接投资的进入将引导东道国发展最终消费品产业，从而促进产业结构变动；但在东道国产业发展到一定阶段后外商直接投资与东道国产业在要素市场的竞争加剧将阻碍东道国产业发展。     

Some Notes on Workplace Equality Renewal in the Swedish Labour Market

In 2001, Swedish authorities imposed a new obligation upon all firms with ten or more employees to undertake annual wage surveys, ‘workplace equality audits’ in which it is possible to ascertain, remedy and prevent unwarranted wage differentials and other unfair employment terms between men and women. An important implication of the new system, called ‘workplace equality renewal’ (självsanering), is that, at the level of the firm all Swedish employers must explain what they mean by work of ‘equal value’ as opposed to ‘different value’. This article discusses the practical pros and cons of the new system, and considers how the surveys can be used in research into the present state of gendered work division. A main finding is that the introduction of this new legislation in the long run might change the Swedish industrial relations system as well as the preconditions for many companies’ human resource management policies. Yet, neither the governmental agencies involved nor the parties’ confederate organizations have been able to clarify what the issue is really about to the single, small business employer or to the local trade union branches. Many employers find any interference, whatever it may be, threatening and trade unions have not realized the potentialities of the system from an employee perspective, potentialities connected to the fact that companies are now more or less forced to make transparent their wage policies at large.
