基于动态调整模型的最优资本结构影响因素实证研究

本文引入调整成本这一概念,构建了资本结构的动态调整模型。并基于面板数据分析方法,采用我国上市公司的最新财务数据和宏观经济指标,对动态调整模型进行了实证分析。实证结果表明,我国上市公司的资本结构的确存在向最优值部分调整的现象,在动态调整过程中的交易成本较小,这使得我国上市公司的资本结构调整到最优资本结构的比例较高。     

新常态下贸易调整与中国经济周期波动

本文构建了小型开放经济下多部门动态随机一般均衡模型,通过分析进口占比和国内外产品替代 弹性的动态变化来研究贸易调整时期宏观经济的动态调整机制。数值模拟结果表明,贸易调整的策略和路径对不 同冲击下经济运行的影响存在差异;国内经济冲击下的贸易调整会对经济稳态产生影响,国外经济冲击下的贸易 调整对国内经济长期运行影响不显著,但是会影响短期经济调整;进口占比主要影响消费、资本、投资和实际汇率, 国内外产品替代弹性则主要影响资本、经常账户和实际汇率。

通货膨胀福利成本研究述评

通货膨胀福利成本问题不仅是货币政策理论的一个重要内容,也是国家宏观经济政策制定的重要依据。本文在对国内外有关通货膨胀福利成本研究成果进行系统述评的基础上指出,由于中国二元经济特征及资本市场的不成熟,仅仅简单地按照国外研究中已有的模型对我国通货膨胀福利成本进行估算存在较多的局限性,因此,必须根据中国的现实约束条件,提出适合中国国情的理论框架与实证研究。     

财政政策、货币政策调控与宏观经济稳定——基于新凯恩斯主义垄断竞争模型的分析

本文基于包含金融加速器的新凯恩斯主义垄断竞争框架,研究了财政政策和货币政策冲击对我国宏观经济的影响。实证结果表明,财政政策能够解释部分就业、消费和资本存量波动;货币政策冲击则能够解释大部分通货膨胀、就业波动,以及部分产出、消费和投资波动。总体上,模型能够较好地刻画中国宏观经济波动特征。本文认为今后一段时期内,应当将财政政策更多转向民生领域和基础设施建设,重视货币政策调控,从而更有效地调控宏观经济运行。     

通胀形势凸显经济深层次矛盾

3月份宏观经济数据再次凸显中国经济深层次调整的巨大压力。一面是生产价格指数(PPI)在28个月以来首现负增长,一面却是消费价格指数(CPI)同比上涨3.6%,PPI与CPI之间的"价格差"越拉越大。PPI的负增长表面,实体经济需求不足,企业难以把上游的成本

Development in Information and Communications Technology (ICT) Statistics at the Australian Bureau of Statistics

This paper outlines the ICT statistical developments that the ABS has undertaken over recent years. These developments have been on both the supply side (ICT industry) and the demand side (use of IT by sector). The content of ABS ICT surveys has changed significantly over the last few years and are expected to develop further in line with industry changes and emerging policy needs.
Recent developments in household collections have been the inclusion of IT use questions in the 2001 Census of Population and Housing and in various ABS social surveys such as Children's Participation in Culture and Leisure Activities. Annual business IT use surveys are now conducted and include topics such as Internet commerce and IT security. Biennial ICT industry surveys are conducted to provide data on ICT production, imports and exports, ICT industry employment, performance and structure information. An Internet activity survey is run every six months and provides regional Internet access details and infrastructure details on Internet service providers.
A major development for 2002–03 will be the compilation of an ICT satellite account. ABS intends to produce an ICT Information Development Plan to guide its future statistical development work in the ICT field.     

Value at Risk in the Suburbs: Eminent Domain and the Geographical Politics of the US Foreclosure Crisis

Several US counties and local governments have recently considered a novel solution to the foreclosure crisis. They plan to use eminent domain to compel the owners of mortgage debt—and specifically of private‐label mortgage‐backed securities—to sell the debt to the government at a price reflecting the loan's market value. The government would then restructure the debt and resell it to new investors. The plans are striking because—in contrast to both development‐driven eminent domain and the federal subprime bank bailout—they would force investors to assume asset devaluation and increased long‐term risk. Notably, the plans have emerged as an instance of financialization‐focused politics in suburbs and suburban cities of color, specifically majority‐black and ‐Latino/a suburbs. Local support for the plans, we argue, is rooted in the long‐term disinvestment of these ‘suburbs of exception', which became targets of subprime lending and eventually sites where the ‘financial exception' has been localized. But these demographic shifts, fragmentation and fiscal pressures have at the same time created a suburban political terrain in which the plans have gained their strongest political support.     

Towards a Theory of Serendipity: A Systematic Review and Conceptualization

Serendipity – the notion of making surprising and valuable discoveries – plays a major role in the success of individuals and organizations alike. Previous research has established the importance of serendipity and identified important individual- and organizational-level antecedents. However, the literature has been dispersed and the boundaries of the concept have been blurry, leading to a lack of conceptual clarity and structure, and thus limiting validity and managerial actionability. Based on a systematic literature review, I synthesize existing management-related research on serendipity and explicate the emergence and composition of serendipity in the organizational context. I first identify three necessary conditions that differentiate serendipity from related concepts such as luck or targeted innovation: agency, surprise, and value. Then, I draw from the literature on sensemaking, event-based theorizing, and quantum-based approaches to management to conceptualize the process of cultivating serendipity in the organizational context as a process of enabling potentiality and materialization, and develop a multi-level theory of (cultivating) serendipity. This conceptualization contributes to our collective understanding of how, why, and when (i.e., under what conditions) organizations can leverage the value in the unexpected, which opens up fruitful avenues for further research.     

Accountability of NGOs in Bangladesh A critical overview

NGOs in Bangladesh have been recognized as effective change agents in the socio-economic arena throughout the world. Their contributions in micro credit, non-formal education and primary health care are widely known. NGOs play a significant role in society. NGO accountability, as a result, has become a critical issue. NGO accountability in Bangladesh has been examined here in relation to patrons, clients and themselves. Of the three relationships only accountability to patrons is in a near satisfactory state. Accountability to clients is handicapped by lack of opportunities of beneficiaries to participate meaningfully in NGO policy making. Accountability to themselves is adversely affected due to the adherence to a strictly hierarchical system and the influence of founding and charismatic NGO leaders.     

Towards an Asian model of human resource management? A comparative analysis of China,Japan and South Korea

There has been much discussion regarding the possible decline and weakening of national systems of human resource management (HRM). Yet, culture and institutions are often cited as the major stumbling blocks to this outcome. Such constraints may dissipate in the analysis, particularly if ‘regional clusters’ are considered where geographic and cultural closeness and ‘openness’ to similar economic pressures exist. In such cases, it might be postulated that convergence in HRM will occur. We argue that China, Japan and South Korea represent such a cluster. This article examines these countries, to see if a degree of convergence is taking place and if it is towards an identifiable ‘Asian’ model of HRM. A model of change is presented that distinguishes between levels of occurrence and acceptance. Details of the development and practice of HRM in each country are then set out. The article ends with a discussion and implications section and a brief conclusion.     

The Creation of the Office for National Statistics

A new Office for National Statistics was created in the United Kingdom in 1996 following a series of developments designed to strengthen the relevance and integrity of statistics. This paper describes these fundamental changes and sets out a blueprint for future progress. It also sets current developments in the United Kingdom in an historical and international context.     

What helps? Women engineers' accounts of staying on

We have considerable understanding of the obstacles that women engineers encounter and the reasons that they leave the field, but we know less about what enables them to remain. Adopting an interpretivist approach, this article examines how a group of British women engineers in two FTSE 100 companies account for “staying on” in their male‐dominated work settings. We delineate four specific forms of help that facilitate women's retention in the field. We argue that exposure to help leads to women developing a habitus that enables them to continue working in engineering. To conclude, we draw on our findings to outline HR practices that will facilitate supportive relationships in the workplace and pave the way towards developing more positive organisational climates.

Export Composition and Manufacturing Employment in the US during the Economic Downturn of 1991-92

This paper examines the effect that export composition had upon manufacturing employment in the US during the 1991 recession. Although it takes, on average, approximately $66 000 in exports to create one job, the exact gains in terms of total employment depend upon the labour-intensity of the products being exported. Foreign sales by the chemical and textile industries result in a far greater increase in employment than exports by the petroleum refining or steel industries. This analysis estimates the employment effects of manufacturing exports over the 1989-95 period, utilizing an input-output model to capture both direct and indirect effects. The results demonstrate that export composition has, at times, both strengthened and reduced demand for labour. Consequently, if job-creation is a national goal, it may be in the interests of the US to promote exports from sectors that are labour-using.
