Intermediate accounting instructors need to be engaged in the specific complexities and challenges of the new international financial reporting standards (IFRS) reality within the Canadian multi‐GAAP environment. Intermediate accounting courses are directly affected because they represent substantive coverage of the corporate reporting environment. In this article I make the case that these courses should primarily reflect IFRS standards in order to entrench IFRS competencies in students who wish to pursue a professional designation, to prepare students for the global environment, and to concentrate IFRS expertise issues in a robust instructor group. The competency maps of each of the three Canadian professional accounting bodies clearly reflect IFRS. Students can analyze the implications of major areas of policy differences between IFRS and private enterprise GAAP (PEGAAP) through specific targeted course coverage, but also through active learning elements, particularly research elements. This commentary reflects some of the active debate occurring regarding postsecondary curriculum as Canada adapts to IFRS and PEGAAP, and encourages action.  相似文献

保险公司资产组合与最优投资比例研究   总被引:1,自引:0,他引:1  
保险公司收益主要来源于承保利润和投资收益,其中承保利润受政策变动、市场条件等外部环境的影响较大,而投资收益则更多地取决于保险公司的投资能力,因此保险公司如何构建资产组合、如何确定最优投资比例就是获取投资收益最大化的重要因素。本文通过理论推导得出了保险公司的资产组合模型并运用非线性规划求解出最优投资比例,进而根据保险公司的投资数据进行了实证研究,为我国保险公司的资产组合及最优投资比例提供了一个可借鉴的思路。  相似文献

企业投资效率是影响企业价值的关键因素。本文在划分投资转化过程子阶段的基础上构建投资效率评价模型及指标体系,运用二阶段网络DEA方法测算我国创业板科技创新型上市公司2012~2014年投资效率值及非效率投资的改进程度。实证结果表明,科技创新型上市公司利润产生子阶段投资效率较低,并且研发支出、无形资产以及长期投资三方面的投资冗余现象明显,但是多数上市公司两个阶段的投资效率随着时间的推移逐渐趋向双重高效。  相似文献

本文运用全国与丝绸之路经济带沿线9省区市2003~2014年的面板数据,通过建立空间计量模型,分析了投资结构对产业结构变动的空间效应。结果表明:(1)区域产业结构的变动存在显著的空间依赖性;(2)与全国比较,丝绸之路经济带投资结构对产业结构的调整具有显著的促进作用。非公共基础设施投资对产业结构合理化、高级化的积极作用最大,尤其是对西北地区产业结构合理化,西南地区高级化的作用较大,而对全国呈现出消极效应;(3)硬性基础设施投资对西北地区产业结构合理化和高级化的积极作用最明显,而软性基础设施投资对西南地区产业高级化的贡献较大。表明调整丝绸之路经济带投资结构能够提高本地和相邻地区产业结构的优化升级。  相似文献

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.  相似文献

SUMMARY

We address the question of competition within the location choices of firms. In a framework of agglomeration effects, both spatial and temporal dimensions of the firms' decisions are studied. We show that the competition consequences of preemptive move and optimal time of entry can interfere with the geographical decisions. Our results contrast with those of agglomeration economics models which generally provide extreme results of mono-location. The equilibria described here tend to demonstrate that the relation between competition strength and spatial differentiation remains pertinent in a context of agglomeration economies. A conditional logit empirical study analyses the geographical choice of Japanese firms in Europe. Agglomeration variables, public policies and labour market determinants are tested, highlighting the existence of temporal and spatial proximity in the behaviour of firms. The competition conditions experienced by firms of each specific sector also appear to be important in the location decision of Japanese investors.  相似文献

Abstract

As Vietnam opens up its economy through a series of economic reforms, entrepreneurs from both Western and Asian economies are flocking to the country to share in its rapid growth. In view of the growing foreign interest in conducting businesses in Vietnam, this paper attempts to provide an overview of the political, economic and business environments in the country. Although the country is full of opportunities, it may pose several problems and challenges to new players as well. Thus, this paper will further discuss the possible investment issues and challenges facing foreign companies which are considering venturing into Vietnam. Some cultural characteristics and operating rules during business interactions in Vietnam are discussed. Common mistakes committed by foreign companies entering the country are also highlighted. It is hoped that this paper will provide an in-depth understanding of the Vietnamese business environment and help improve the likelihood of the successful venture performance of international investors, thus benefiting both the foreign investor and the growth of Vietnam in the global marketplace.  相似文献

Abstract

Social enterprises are being promoted as responsive and innovative way to deliver public services. As part of this promotion, these organizations are being required to demonstrate the social and economic value they generate. Social return on investment (SROI) is a performance measurement tool currently being encouraged to capture this impact. This paper draws on survey and interview data to analyse how SROI is used and understood in health and social care settings. It indicates that despite being accepted as an internationally recognized measurement tool for social enterprise, SROI is underused and undervalued due to practical and ideological barriers.  相似文献

This paper provides statistical information on internationalization, human resources and labour market outcomes in ten important developed market economies (DMEs). Such data are useful for practitioners and academics who are interested in international HRM. The article's aim is to provide easily accessible statistical tables of selected characteristics, which can be used to draw initial comparisons between countries and to test competing accounts of the impact of globalization on national patterns of employment relations. It includes standard sources so readers can elaborate and update these data.  相似文献
