In this paper, we present a new methodology for modelling intraday volume, which allows for a reduction of the execution risk in VWAP (Volume Weighted Average Price) orders. The results are obtained for all the stocks included in the CAC40 index at the beginning of September 2004. The idea of considered models is based on the decomposition of traded volume into two parts: one reflects volume changes due to market evolution; the second describes the stock specific volume pattern. The dynamic of the specific volume part is depicted by ARMA and SETAR models. The implementation of VWAP strategies allows some dynamic adjustments during the day in order to improve tracking of the end-of-day VWAP. 相似文献

The performance of the New Zealand (NZ) economy is something of an enigma. Although ranked one (of 144 countries) for four important ‘growth fundamentals’ NZ is ‘middle of the pack’ when it comes to economic growth, productivity and process innovation. Using four iterations (2005, 2007, 2009 and 2011) of the Business Operations Survey, this research seeks to shed some new light on this conundrum by using a multivariate probit regression (mvprobit) approach applied to pooled samples in excess of 22,000 unit record observations of NZ firms. The results suggest that factors including firm size, high perceived quality, investment/research and development (R&D) capability, major technology change, application of formal IP protection and new export markets are systematically and positively related to innovation; while many external issues, such as those related to geography, market structure, business environment, have little influence. At the firm level, innovations in NZ are highly dependent on the firms’ internal ability to develop new technologies and market demand. The (very small) size of firms does matter in NZ, which lacks a major ‘home market’ or a major trade block on its doorstep, such that ultimately, government may need to be involved to maintain a viable scale for domestic R&D. 相似文献

With Monte Carlo experiments on models in widespread use we examine the performance of indirect inference (II) tests of DSGE models in small samples. We compare these tests with ones based on direct inference (using the Likelihood Ratio, LR). We find that both tests have power so that a substantially false model will tend to be rejected by both; but that the power of the II test is substantially greater, both because the LR is applied after re-estimation of the model error processes and because the II test uses the false model’s own restricted distribution for the auxiliary model’s coefficients. This greater power allows users to focus this test more narrowly on features of interest, trading off power against tractability. 相似文献

This paper analyzes the relationship between government expenditure, tax on returns to assets, public debt, and growth in an endogenous growth model. Public debt is composed of two components, domestic debt and external debt. We show conditions for existence, uniqueness, and multiplicity of the steady states. More precisely, existence of steady state requires a sufficiently high productivity and a sufficiently low tax on returns to assets. We also provide the effects of an increase in the tax rate on returns to assets on the steady state. In particular, the relation between public spending and the tax rate has a bell shape. Domestic debt unambiguously increases with tax whereas external debt displays an inverted U‐shaped curve. A high tax rate leads to a reallocation of public debt in favor of domestic debt (to the detriment of external debt). The effect of taxation on consumption (and production) also displays a nonlinear pattern when the output elasticity of capital is lower than unity (the effect is monotonously increasing if this elasticity is unity). We also derive the conditions under which a tax increase can boost or reduce the balanced growth rate. 相似文献

全球劳动力老化的严峻形势下,年长员工能否主动分享知识经验,对充分开发年长人力资本、促进企业可持续发展具有重要意义。基于主动动机模型,本文从责任导向视角探讨了年长员工知识分享行为的促发机制和边界条件。通过线性回归和蒙特卡洛拔靴法对200份40岁以上在职员工三时点配对数据进行分析,结果表明:责任导向会通过提升年长员工的建设性责任知觉进而激发其知识分享;反年龄歧视氛围感知对这一作用过程具有权变影响。本文丰富了年长员工知识分享行为的前因研究,对企业如何积极应对职场老龄化与年长员工知识传承具有启示意义。 相似文献

China has been losing international competitiveness in labor-intensive industries due to various factors, including the trade war with the United States and globalization. Vietnam, however, has rapidly expanded its labor-intensive exports. The paper proposes to explore the future of labor-intensive industries in Vietnam due to the U.S.-China trade war. The paper examines export performance data from United Nation Comtrade for 10 specific labor-intensive industries that serve the U.S. market between 2000 and 2020 to assess the possibility of Vietnam overtaking China's position as the world's largest manufacturer. Using situation analysis, the paper compares the competitive advantage of Vietnam in labor-intensive industries due to the U.S.-China trade war. The paper found that China's competitiveness was negatively impacted for the final two periods, while Vietnam's competitive advantage increased. 相似文献

日本的能源政策与能源安全 总被引:6,自引:1,他引:5
2004年6月新出台的日本“基本能源政策”强调,进一步寻求能源多样化鼓励使用天然气以减缓气候变化,减少石油在能源结构中的比例以有效减少对中东石油的依赖。核电政策依然是日本能源政策的核心。目前日本已经有52个核反应堆,计划到2010年和2050年,分别再建造4个和6个新的核反应堆。为了实现《京都议定书》规定的二氧化碳减排指标,日本环境省拟对石油、煤炭、天然气和电力的使用,按照碳含量征税。但该计剐目前受到来自各方的反对。2004年2月29日成立的日本石油是然气金属矿产资源机构(JOGMEC)已从即将解散的石油公团手中接管了国家石油储备的全部管理职责。原有的8家国家石油储备公司现已实行私有化。为改善地区和国家能源安全,日本政府迫切希望建立“10 8”能源安全体系和东盟的联合石油储备。同时,还鼓励中东主要石油出口国投资于日本石油的下游业。2004年8月,沙特阿美石油,公司作为沙特国家石油公司已首次投资日本炼油厂。 相似文献
