External constraints and endogenous growth: Why didn't some countries benefit from capital flows?

Empirical evidence on the growth benefits of capital inflows is mixed. The growth benefits accruing from capital inflows also appear to be larger for high savings countries. We explain this phenomenon using an OLG model of endogenous growth in open economies with borrowing constraints that can generate both positive and negative growth effects of capital inflows. The amount an economy can borrow is restricted by an endogenous enforcement constraint. In our setting, with physical capital and a pay-as-you-go pensions system, the steady state is unique. However, it can either be constrained or unconstrained. In a constrained economy, opening up to equity and FDI inflows can be bad for growth because it makes the domestic interest rate too low, which endogenously tightens borrowing constraints. Agents decrease savings and investment in productivity-enhancing activities resulting in lower growth. Results are reversed in an unconstrained economy. We also provide a quantitative analysis of these constraints and some policy implications.     

我国油气资源税由从量计征改为从价计征的政策效应——基于双重差分法的计量分析

基于双重差分法,对西部地区油气资源税由从量计征改为从价计证的政策效果进行评估,以单位产值能耗、污染排放量和人均资源税收入作为政策效果变量,实证研究表明,油气从价税改革促使西部地区单位产出能耗相对于样本均值下降了7.90~8.55个百分点,污染排放量减少约1556吨,人均资源税收入相对于样本均值增加了2.74~3.03个百分点,通过采用不同处理方法进行稳健性检验后,以上结论仍然成立。     

股票资金流强度的实证研究及评测

在资金博弈的股票市场中,资金流向确认与计算是金融工程的一大理论难题,国内有学者在现有资金流计算方法基础上,提出了股票资金流强度模型和构建了股票资金流指数指标体系。根据统计分析方法利用SPSS软件对股票资金流强度和股价波动环比增长率进行相关性分析,进而实证股票资金流强度指标的有效性。实证结果表明股票资金流强度与股价波动环比增长率呈线性趋势,从而利用股票资金流强度指标可以很好地预测股价的变化。     

The external wealth of nations mark II: Revised and extended estimates of foreign assets and liabilities, 1970-2004

We construct estimates of external assets and liabilities for 145 countries for 1970-2004. We describe our estimation methods and key features of the data at the country and global level. We focus on trends in net and gross external positions, and the composition of international portfolios. We document the increasing importance of equity financing and the improvement in the external position for emerging markets, and the differing pace of financial integration between advanced and developing economies. We also show the existence of a global discrepancy between estimated foreign assets and liabilities, and identify the asset categories accounting for this discrepancy.     

Liquidity implications of reverse logistics for retailers: A Markov chain approach

The reverse logistics process can generate periodic negative cash flows that are difficult to predict and account for, but are important when managing retailer liquidity. Uncertainties surrounding reverse logistics create the possibility that the retailer may be strained in meeting short-run financial obligations or opportunities. The current research offers a Markov chain approach to modeling the expectations, risks, and potential shocks associated with cash flows stemming from retail reverse logistics activities. Managerial recommendations for avoiding liquidity problems stemming from reverse logistics activities are provided.     

物流文化的作用及其建设思路

在激烈竞争的形势下,加强我国物流文化建设非常必要。为此,物流企业必须准确把握物流文化建设的基本目标,强化物流文化的塑造过程,积极学习新知识,不断丰富物流文化内涵。     

物流过程中的可再生资源的回收和利用

企业再生资源是企业生产加工制造过程中,尚有使用价值的排放物。企业可再生资源种类繁多,地点分散,因此,对再生资源的回收和利用提出了特殊要求。本文从我国可再生资源的概念、种类和物流特点分析入手,并在此基础上提出我国企业对可再生资源的回收利用途径。     

中国地区间研发资源错配测算与影响因素分析

随着中国的研发投入总量进入世界第一梯队,研发投入(资源)的配置状况成为决定研发产出效率的关键因素之一。本文基于一个包含研发资源价格扭曲的多部门竞争均衡模型,以2001—2016年各省份规模以上工业企业数据为样本,对中国地区间研发资源错配情况及其影响因素进行全面考察。研究发现:(1)各省份之间的研发劳动错配高于研发资本错配,多数省份倾向于过度配置研发资源,省份之间研发资源配置效率总体上呈逐步改善趋势,纠正错配可以使研发产出提升约16%;(2)东部各省份研发资源配置相对较为合理,但研发劳动配置略有不足,中部、西部和东北各省均存在不同程度的研发资源过度配置现象,东部和西部的研发资源配置效率一直在改善,东北和中部则没有表现出持续的改进态势;(3)市场发育程度、偏向性政策扶持、地区创新环境是研发资源错配的主要影响因素,在研发资源过度配置地区,这些因素的作用更为显著。本文的启示是,在当前全面实施创新驱动发展战略的大背景下,政府相关部门在积极引导全社会加大研发投入力度的同时,还应以市场为导向,进一步优化不同地区间的研发资源配置,实现研发效率的提升和经济的高质量发展。     

人民币汇率价格信息传导机制研究 ——基于离岸和在岸即期市场的实证分析

随着人民币国际化进程的不断推进,离岸与在岸的人民币即期汇率市场之间开始有均值(或波动)的相互影响。该价格信息传导机制具体表现为:两个市场之间存在均值和波动溢出效应,并且均值溢出效应不太稳定,波动溢出效应相对稳定;内部因素的变化往往会改变价格信息传导的方向和作用,而外生冲击的影响则相对有限;当期升值较快的市场往往会主导均值溢出效应,但波动溢出效应是由受政策预期影响的在岸市场所主导;利好消息会减少离岸市场的波动,但会加大在岸市场的波动。     

浅析文化企业人力资源创新——基于美术文化企业人力资源管理现状分析

竞争日益激烈的文化市场竞争使越来越多的文化企业尤其是美术文化企业开始意识到仅仅重视文化本身和营销并不能使其保持优势,只有将人力资源与企业本身结合,才能衍生出企业独特的优势。本文试图通过美术文化企业人力资源管理的现状,探讨人力资源管理在企业中的作用,并探讨实现人力资源最优化的创新策略。
