民营经济融资的P2P模式探析

民营经济在国民经济和社会生活中均扮演着重要角色,在增加税收及就业方面发挥了重要作用,但民营经济存在的融资困境是其发展瓶颈。通过对民营经济自身制度的缺陷、内源融资比重过高、商业银行贷款门槛高、放贷意愿低等融资现状的分析,并结合互联网金融大环境下P2 P融资模式的创新,提出利用P2 P融资模式在门槛低、交易成本低、资金运用效率高等方面的优势是解决民营经济融资困境的首要选择。     

Decision Support Systems in Marketing

The practical application of decision support systems in marketing is still in its infancy, even though academic research has been recommending the use of such systems for years. This is largely due to the lack of a single, generally applicable decision support system. The specific requirements and problems of management are too dissimilar to make the development of one universal decision support system feasible. However, improved PC performance, enhanced market survey methods such as conjoint measurement, and further developed programming tools permit the varying requirements to be fairly flexibly met. The following article describes state-of-the-art know-how regarding the practical utilization of such systems, and addresses the preconditions for employing them. We have included many examples gathered from our own experience with numerous applications.     

The effects of integration agreements in Western Hemisphere trade, 1970–2014

The paper analyzes the effects of four regional integration agreements (Common Market of the South [MERCOSUR], Andean Community [ANCOM], Central American Common Market [CACM] and North America Free Trade Agreement [NAFTA]) on bilateral trade in 19 countries from the Western Hemisphere for the period 1970–2014. For this purpose we estimate different gravity models to control for trade creation and diversion, export diversification and intra-industry trade using OLS log-linearized gravity model and Poisson pseudo-maximum-likelihood panel data estimators that allow controlling for zero-value trade flows. We find trade creation for ANCOM, MERCOSUR and CACM and trade diversion for NAFTA and MERCOSUR countries. Export diversification negatively affects bilateral trade in all American agreements, while intra-industry trade has contributed to trade expansion in ANCOM and the opposite for NAFTA, MERCOSUR and CACM. Global supply chains may help us explain these results. Finally, we find anticipatory effects on trade several years before the signing of the agreements, but only NAFTA countries seem to be natural trading partners in the region while the rest of Latin American regional agreements have not resulted in a comprehensive, profound and consolidated common market.     

Combining revealed and stated preferences data

Our objective is to develop a unifying framework for the incorporation of different types of survey data in individual choice models. We describe statistical methodologies that combine multiple sources of data in the estimation of individual choice models and summarize the current state of the art of data combination methods that have been used with market research data. The most successful applications so far have combined revealed and stated preference data. We discuss different types of market and survey data and provide examples of research contexts in which one might wish to combine them. Although these methods show a great deal of promise and have already been used successfully in a number of applications, several important research issues remain. A discussion of these issues and directions for further research conclude the paper.     

代际再分配与我国养老保险模式的选择

代际再分配是指收入在不同代之间进行的又一次分配,在代际交叠模型中,经济是由不同代的年轻人和老年人组成的。在竞争市场均衡的代际交叠模型中,现收现付制与完全基金制两种保险模式对资本存量以及不同人福利有着不同的影响。人口年龄结构的变化,将对养老保险中的代际再分配产生怎样的影响,是一个颇具新意而且具有现实意义的问题。     

FDI、国际贸易及我国经济增长的协整分析与VECM模型

本文利用我国1983-2004年的经济数据进行实证检验,根据协整理论建立向量误差修正模型(VECM)。实证结果说明外国直接投资、国际贸易与经济增长间具有长期均衡关系,且我国国内生产总值的增长与外国直接投资有双向因果关系,但相互影响的程度不同;我国为出口导向型经济增长国家且外国直接投资对国际贸易具有促进作用.     

航空客运收益管理中的渠道管理问题研究

传统的存量控制研究的解决方案是以直接面对最终顾客为前提的,没有将销售渠道的需求分布考虑在内,因而也就不能把分配给各个销售渠道的机票数量进行科学控制和优化。不同的销售渠道对同种类型机票的需求分布不同,并且给航空公司带来的最终收入不同,因此,随着联网售票系统的完善和电子商务的发展,如何更好地管理销售渠道,给那些能给航空公司带来更多收益的销售渠道预留足够的座位,已经成为航空公司不容忽视的问题。     

房地产上市公司资本结构的影响因素分析

房地产上市公司资本结构的影响因素有其行业的特殊性,利用随机前沿面模型实证分析表明：偿债能力与总资产负债率呈显著的负相关关系,而且短期偿债能力主要通过影响短期负债对总资产负债率产生巨大的影响;ROA与总资产负债率负相关,ROE与总资产负债率正相关,而且ROA对总资产负债率的影响要大得多,短期负债对ROA的影响更加明显;成长性和公司规模都对资本结构具有正面影响;非国有控股比国有控股房地产上市公司更有利用财务杠杆的动机,而且明显倚重短期负债。房地产上市公司应努力改善资本结构,特别是需要降低短期负债比重,提高短期偿债能力来有效化解财务风险,应建立更加严格的风险防范体系。     

专业市场形成与发展的制度求解

专业市场是在我国经济体制改革大背景下,适应商品经济发展而创新形成的一种制度安排。它并不是基于原有制度安排基础上的转换和修正,而是一种新的流通组织形式。为此,从制度变迁的三个经典理论模型出发,探寻专业市场形成与发展的制度求解。     

基于多Agent的协同供应链模型

供应链通过获取原材料,转换成最终产品,交付最终用户等一系列过程将供应商、制造商、仓储、分销中心以及零售商等形成一个巨大的网络体系。当前,随着企业经营模式的变化,协同与伙伴管理成为供应链变革的推动力量。而协同供应链能够对市场变化和用户需求形成快速响应。将Agent理论应用于协同供应链管理,分析协同供应链的主要特征,并提出基于多Agent的协同供应链模型。
