服务进口与我国全要素生产率的增长——基于VAR模型的实证研究

服务进口贸易对我国全要素生产率的增长有多大的促进作用事关我国经济增长方式的转变。实证研究结果表明,1985-2010年,服务进口贸易与我国全要素生产率的变化之间有显著的正相关关系,服务进口增长1%,全要素生产率就有0.12%的提升。基于VAR模型的脉冲响应函数分析和预测方差分解分析结果,尽管国内RD资本存量对全要素生产率的长期拉动效应更为显著,但服务进口的积极作用也不可忽视。     

广州市财政收入影响因素的实证研究——基于VAR模型分析

财政收入是衡量一国政府财力的重要指标。为了探究广州市财政收入的影响因素,以1978—2011年广州市的相关数据为例,应用VAR模型分析影响广州市财政收入的因素。研究结果表明,经济发展水平、产业结构、就业人数、固定资产投资和税收水平对财政收入存在长期稳定的协同关系,且这种均衡协同关系具有反向修正机制,各因素对财政收入的影响程度存在差异。     

The path of lease resistance: How changes to lease accounting treatment may impact your business

In this installment of Accounting Matters, we examine potential consequences of the Financial Accounting Standards Board's Proposed Accounting Standards Updates for Leases. In the context of a previous accounting change (FIN 48), we investigate how these changes will affect firms’ accounting choices, investment decisions, debt covenant requirements, and analysis of other key financial data. Changes in accounting standards may have significant indirect economic effect on companies as they can trigger debt covenant violations, restrict access to capital, and distort key financial information used by investors and lenders. New accounting standards may also directly affect the calculation of employee bonuses and incentives that utilize EBITDA or operating income as benchmarks. We include recommendations for managers and identify specific debt covenant components that may limit the negative consequences of the proposed change to lease accounting.     

人口城市化与经济增长、产业结构间的动态关系——以江苏省为例

基于已有的研究理论和经验,采用VAR模型对江苏1980-2010年间人口城市化、经济增长及产业结构之间的关系进行了研究。实证结果表明:江苏的人口城市化与经济增长、产业升级间有长期的累积循环效应,但效应较弱;人口城市化有力地促进了经济增长,而经济增长对城市化的提携作用较小;经济增长能带来产业结构的明显提升,但产业结构优化对经济增长的影响是波动和滞后的;人口城市化与产业结构的互动性很弱,甚至两不相干。

Early history of banking in Gothenburg discount house operations 1783–1818

Abstract

For many years Sweden lacked a well-developed banking system. Even by the middle of the eighteenth century, there were no established institutions for the effective mobilising and channelling of capital. However, Sweden's economic development during the eighteen century, when commerce and the production of goods were expanding swiftly, increased the need for some institutionalising of capital movements and the establishment of fixed forms, especially for personal credits. During the latter half of the century, the Swedish Rikshankdid deliberately conduct certain types of operation whose effect was to satisfy a growing demand for capital in some sectors, of the economy. This was effected through such bodies as Manufakturdiskontoen(The Manufacturers' Discount Bank), Generalassistans-kontoret(General Assistance Office), Diskontkompaniet(the Discount Company), Generaldiskontkontoret(the General Discounting Office) and Riksgäldskontoret(the National Debt Office). ¹ On this development generally see Fritz, S., Studier i svenskt bänkväsen 1772-1789, Stockholm 1967 and literature referred to therein.      

国际热钱流人及对中国经济的影响

作为短期投机资本的国际热钱是导致历次金融危机的主要元凶之一。无论是墨西哥金融危机还是亚洲金融危机都给世界人民敲晌了热钱扰害经济的警钟。由于热钱的隐蔽性和流动性往往很难把握其来龙去脉,给各国监管当局造成很大的困难。中国经济的稳定快速发展使人们担忧热钱会搅动中国经济健康发展的局面。文章首先就热钱对经济可能产生的影响进行理论分析,然后利用计量经济模型分析了影响热钱进入中国的因素以及由此给我国的相关经济变量所造成的影响,并针对热钱带来的负面影响提出趋利避害的应对建议。     

新疆公共教育支出与经济发展协调性的实证研究——基于财政性教育支出的视角

区域之间的竞争归根结底是人才的竞争,一个地区教育投入的规模始终影响着该地区教育的现状和未来发展趋势。作为落后地区,新疆跨越武发展目标的实现在很大程度上取决于教育的发展水平。本文通过对新疆财政性教育支出和全国不同区域的比较以及与经济发展水平协调性的实证检验,提出了进一步促进公共教育支出与新疆经济协调发展的政策建议。     

融资融券交易对市场和标的个股波动影响的研究

作为证券市场的重要制度之一,融资融券交易理论上应具有价格发现,价格稳定,提高流动性等基本功能。本文从融资、融券交易对市场和个股两个层面系统而全面的分析融资交易和融券交易的价格稳定作用。对市场波动性的影响的研究上主要借助GARCH族模型,VAR模型,脉冲响应和方差分解等计量分析方法;在对个股的影响上主要是借助面板数据分对个股的总体效应和个体效应展开分析。研究发现：融资交易对指数波动没有显著影响,融券交易对指数波动有一定平抑作用;融资融券交易对标的个股有价格稳定作用,除极个别个股的融资作用表现不确定。     

Labor-supply shifts and economic fluctuations

We propose a new VAR identification scheme that distinguishes shifts of and movements along the labor demand schedule to identify labor-supply shocks. According to our VAR analysis of post-war US data, labor-supply shifts account for about 30 percent of the variation in hours and about 15 percent of the output fluctuations at business cycle frequencies. To assess the role of labor-supply shifts in a more structural framework, estimates from a dynamic general equilibrium model with stochastic variation in home production technology are compared to those from the VAR.
