通过构建包含贸易条件的DSGE模型和SV-TVP-FAVAR模型,依次对中国贸易条件变动的宏观经济效应展开理论解析和动态计量检验。研究发现:(1)贸易条件变动对宏观经济的冲击很大程度上依赖于贸易弹性的高低,当贸易弹性较高时,贸易条件恶化尽管有助于促进就业和经济增长,但对消费和投资将产生显著的"挤出效应";(2)货币政策目标对贸易条件变动的动态传导机制具有重要影响,以价格稳定为目标的货币政策能够有效缓解贸易条件恶化对消费和投资的"挤出效应";(3)中国贸易条件恶化对宏观经济主要变量的影响在短期内和中长期内存在明显不同,并且在不同时期也表现出显著的阶段性差异,相比于两次金融危机时期,经济新常态下贸易条件恶化的产出效应和价格效应相对较小,并且对消费和投资产生的"挤出效应"也有所下降。 相似文献

In order to mobilize the necessary resources for innovation forecasts are unavoidable. However, a forecast is never a neutral or objective assessment. Given an interdependent business landscape, there are at least two major context-related aspects that affect an innovation forecast. First, the actor that makes the forecast is embedded into a specific context. Secondly, the potential innovation stems from a specific environment, and will during the innovation journey be related to other environments in a producing and a using setting, and thus to other investments in place. In this paper we examine the development of one innovation and the forecasts made by three different economic actors. There is an interesting variation in the forecasts that can be explained as a variation of contexts of the actors. The contexts influence the way that the forecasts are done and especially in terms of what the context of the innovation is assumed to be. The empirical findings suggest that the results of the innovation forecast are highly dependent on the actors' abstraction of the business landscape which in turn is affected by the contexts of the actors. 相似文献

ABSTRACTPoor Data Quality (DQ) is amajor culprit in the failure of ERP implantation. Previous DQ solutions focus more on technical approaches, ignoring the importance of seeking the root causes. Therefore, this paper proposes aprocess-driven DQ monitoring framework by Information Product Map (IPMAP). First, IPMAP is applied to visualizethe manufacturing process of critical information products. Then, the potential deficiencies that may arouse DQ problems are examined from the aspects of process and human. Finally, the corresponding DQ improvement strategies are put forward and validated in case study. The results indicate that the framework provides helpful guidance for promoting ERP DQ. 相似文献

This article introduces the special issue that seeks to spur the debate on the challenges of managing people in organizations in Africa. The debate on HRM in Africa has proceeded with tentative steps and now clearly needs to be located firmly within the international management context. It is not the purpose of this special issue to discover or develop an over-arching model of HRM. That has been attempted elsewhere. Our purpose is to bring together the various threads that characterize the on-going debate and hopefully move towards a more specific research agenda which captures the complexity of managing on the African continent. Some of these threads include the formulation of new perspectives on HR research, finding common ground with diverse disciplines and tackling enduring problems like ethnicity and discrimination. 相似文献

The Lake Wobegon Effect (LWE) describes the potential measurement-error bias introduced into survey-based analyses of education issues. Although this effect potentially applies to any student-report variable, the systematic overreporting of academic achievements such as grade point average is often of preeminent concern. This concern can be easily circumvented if official records data are available; however, many researchers can only access student-reported data. In this article, the authors examine whether using student-survey data in place of official records data meaningfully biases regression estimates. They motivate their contribution by noting a useful statistical feature of overreporting on bounded variables such as grade point average. Specifically, the misreports will be negatively correlated with the true grade point average, yielding a form of nonclassical measurement error that actually counteracts the bias. The authors connect this observation to reliability ratios used in labor economics, which are simple ways to adjust for attenuation bias, when needed. In two applications, we find that it is unnecessary to correct for the LWE bias because it is so small. 相似文献

网络点击合同的效力不等同于传统格式合同效力,从主体缔约能力的确定、意思表示的真实性、电子格式条款的效力判定分析有助于维护消费者权益,实现网上交易的公平。设立网店实名制度和撤销权制度等配套制度、规制网络点击合同电子格式条款是网络消费者权益保护的法律应对措施。 相似文献
