The Effects of Occupational Injuries After Returns to Work: Work Absences and Losses of On-the-Job Productivity

We extend the research on postinjury employment by estimating productivity losses for workers with permanent partial disabilities (PPDs) in the first three years after injury. Our method distinguishes between productivity losses attributed to spells of work absence versus reduced earnings during spells of employment. The method is applied to data for 800 Ontario workers with PPDs. The results document large productivity losses persisting at least three years after injury, with different loss patterns for workers returning to stable versus unstable employment. Human capital investments or job accommodations can reduce productivity losses, but the significant determinants of losses differ for the stable versus unstable employment groups.     

不同财务管理目标下业绩评价选择及其关系处理

从财务管理目标出发考察企业业绩评价方法的演变过程，是为了在它们之间建立一种联系。不同的财务管理目标下，企业的业绩评价选择会有很大的差异，而其总体趋势是选择综合业绩评价方法。在不同的财务管理目标下选择不同的业绩评价指标时，又要处理好三对关系：短期发展与长期发展、局部利益与全局利益、财务指标与非财务指标。     

英国生产服务业发展现状分析

本文利用1968-2002年间的英国投入产出表,将英国服务业中用于中间需求的部分界定为生产服务业,并由此分析了英国生产服务业的发展趋势及现状。分析发现,英国生产服务业增加值占服务业和GDP比重不断上升,与人均GDP之间存在显著的正相关关系。生产服务业中为农业、工业服务的部门比重不断下降,而为服务业服务的部门比重不断上升。文章最后分析了英国生产服务业发展变化趋势对我国的几点启示。

Gentlemanly capitalism in New Zealand

This article responds to McAloon's contribution to this journal criticising the argument advanced by P.J. Cain and myself in British Imperialism . McAloon's research on Canterbury and Otago merits serious attention, but it is argued here that he is mistaken in claiming that it disproves the case we made for applying our concept of gentlemanly capitalism to New Zealand. Both the structure of 'settler capitalism' and the social characteristics of the settlers themselves provide a good fit with our interpretation. Nevertheless, McAloon deserves credit for putting this subject on the agenda, and it is to be hoped that other historians of New Zealand (and also of Australia) will now reconsider the relationship between the 'rules of the game' established by the imperial centre and the degrees of dependence experienced by the constituent parts of the empire.     

我国港口投融资政策的思考

一、我国港口投融资现状与问题目前我国有近1500个港口,对外开放的港口达130个,每年接纳世界100多个国家和地区的36000多艘船舶,基本上形成了大中小配套、通用性和专业化兼备的港口体系。这些港口的建设资金,从投资来源上讲,主要是国家、省、市财政投资和企业自有资金的投入。它有力地保证了港口设施建设,促进了港口的发展,为经济发展起到了重要的作用。但随着改革的不断深入,单纯依靠国家财力和企业自有资金来从事港口建设,已越来越不能满足经济发展的需要。近年来,尽管国家对港口建设的投资力度在不断加大———1995年投资68亿元,2000年81…     

Estimating the Size of a Criminal Population from Police Records Using the Truncated Poisson Regression Model

The truncated Poisson regression model is used to arrive at point and interval estimates of the size of two offender populations, i.e. drunk drivers and persons who illegally possess firearms. The dependent capture–recapture variables are constructed from Dutch police records and are counts of individual arrests for both violations. The population size estimates are derived assuming that each count is a realization of a Poisson distribution, and that the Poisson parameters are related to covariates through the truncated Poisson regression model. These assumptions are discussed in detail, and the tenability of the second assumption is assessed by evaluating the marginal residuals and performing tests on overdispersion. For the firearms example, the second assumption seems to hold well, but for the drunk drivers example there is some overdispersion. It is concluded that the method is useful, provided it is used with care.     

Dividend reinvestment plans: An empirical analysis

This study examines the effect of initiating discount and no discount dividend reinvestment plans on shareholder wealth. The results show a negative response to DRP announcements, which is significantly smaller than that found in studies of new equity offerings. These results are consistent with the Scholes and Wolfson (1989) hypothesis that managers in need of equity capital use DRPs to mitigate the adverse stock price effects of new equity issue announcements. Furthermore, there is a significant difference in the price response of discount and no discount DRPs for industrial firms. This result is supportive of the signaling potential of discount DRPs. Supportive evidence is also found in the analysis of firm characteristics for industrial firms.     

TESTING FOR INTEGRATION IN EUROPEAN COMMUNITY AGRICULTURAL PRODUCT MARKETS

The degree of spatial market integration in European Community agricultural product markets is investigated. The methodology is based on co-integration analysis. A two-step testing procedure is applied to test the existence of the ‘Law of One Price’ which should be in force if these markets are truly integrated. The results show that market integration has not been achieved in a number of cases even when MCAs are subtracted from the price series used.
