The effects of quantification on persuasion in unfamiliar contexts: The case of information systems controls

The purpose of this study is to more fully understand when quantitative analyses are more persuasive than qualitative analyses. Forty-seven executives responded to an experiment where they evaluated a business proposal recommending an increase in the information systems controls budget, where potential benefits were presented via either a quantitative or qualitative analysis. When the executives were familiar with the context, the quantitative analyses were more persuasive. However, when the executives were less familiar with the context, qualitative analyses that were framed negatively were more persuasive than quantitative analyses. These findings are important theoretically and pragmatically. From a theoretical standpoint, I demonstrate that familiarity with the context predicates how quantification affects decision-makers. In addition, I offer evidence that qualitative analyses that emphasize what has been, or could be, avoided may be a viable persuasive tactic when the decision-maker is unfamiliar with the context.     

Relevance or irrelevance of capital structure?

In this paper we examine the effects of asymmetric information on the nature of financial equilibrium and on the capital structure of firms. In the first model presented, the financial contracts on offer involve pooling equilibrium with no adverse selection. However, in the special case analyzed, where contracts are of mixed form, there may be a separating equilibrium and also equilibrium may not exist. Interesting result is that the separating equilibrium found is not economically efficient since aggregate investments falls short of first-best level. More importantly, capital structure does matter. The relative magnitude of outside equity makes a real difference to the quantity of aggregate investment in equilibrium.     

在线广告发布的位置模式对消费者品牌选择影响的仿真研究

在线广告发布的位置模式的选择要考虑在预算约束的情形下实现投资回报最大化，对于厂商在线营销具有重要意义。文章以消费者低程度介入的快速消费品为研究对象，使用消费者品牌选择研究中常用的多项Logit模型就在线广告发布的位置模式对消费者选择的影响进行了仿真研究。在线广告发布的位置模式主要分为水平式、上升式、下降式和交替式四种模式。研究发现，上升式的位置模式发布广告对消费者的品牌选择效果最好，水平式次之，交叉式第三，下降式最差。     

技术扩散和经济增长：一个空间计量模型研究

本文在扩展空间MRW模型的框架下基础考虑各经济变量之间的相互依赖性，并放弃技术进步是外生的假设，将其内生化，认为技术的进步对于经济增长作用显著。另外强调了技术在空间上的扩散，经济集聚等因素对于经济增长的重要作用，本文建立的扩展的RWM理论模型认为一个地区的技术进步率，储蓄率，人口增长率以及相邻地区的加权储蓄率加权人口增...     

城市客运交通系统结构研究

在解析城市客运交通系统合理结构的基础上,根据居民出行方式选择随距离和综合交通条件而变化的内在规律,以居民出行距离分布特征为基础,论证常规公交与城市轨道交通出行全过程广义效用值边际效应,综合构建城市客运交通方式出行选择模型。以某中心城市为例,计算结果表明:以出行距离分布特征为基础,考虑城市综合交通条件,结合未来客运结构辨识而建立的城市出行方式选择模型具有较好的拟合特征和适用性。     

区域经济协调发展的GACH-X作用机制的实证研究

笔者从区域经济发展的社会、经济、资源与环境子系统的关联性出发,基于增长、依附、竞争、和谐的内在机理,探讨了区域经济协调发展的GACH-X作用机制。基于结构方程模型,利用全国区域经济相关数据,对该机制进行实证研究,研究结果表明:增长、依附、竞争、和谐4个要素均与区域协调发展之间具有正相关关系。     

财政压力、土地财政与区域房价的时空演化--基于GTWR模型的实证研究

通过分析财政压力与土地财政对区域房价的影响机理,来构建三者之间的关系模型,同时考虑到财政压力与土地财政对区域房价的影响存在时空异质性,采用GTWR模型对模型参数进行估计,研究了财政压力、土地财政对房价的直接效应与间接效应,并对其时空异质特征进行了实证研究。结果显示:财政压力、土地财政对房价整体上具有正向直接效应;财政压力通过土地财政对区域房价起到正向的间接效应;财政压力和土地财政及两者互动对房价的影响效应存在较大的时空差异,其中东部地区和中部地区由于较高的土地财政依赖而以间接效应为主,而西部地区则以财政压力对房价的直接效应为主。最后,提出相应的政策建议。     

个人消费者网络虚拟团购模型构建及优化

本文在分析研究目前网上拍卖所存在的问题的基础上,构建了基于消费者采购目标的网络虚拟团购模型,在此模型中,个人消费者采购的产品的价格将大大降低,无论是企业消费者还是个人消费者都将享受数量折扣和累加数量的价格折扣,从而保证虚拟团购的顺利实施.

Integrating the Dirichlet-multinomial and multinomial logit models of brand choice

This paper discusses the interpretative benefits that arise from merging the Dirichlet-multinomial (DM) model as a loyalty variable in the multinomial logit (MNL) model of brand choice. The estimated parameters of this hybrid model compare favorably to those of a pure DM model (with no marketing mix variables) as well as those of a standard MNL model with an exponentially smoothed loyalty measure. The hybrid model offers an index of consumer heterogeneity and estimates of each brand's preference share, adjusted for the effects of price and promotional activities. We illustrate the unique interpretations offered by these parameters across four different product categories, showing how changes in heterogeneity (across categories or model specifications) are closely related to changes in the overall impact of marketing mix variables.The author is grateful to Bruce Hardie, Barbara Kahn, Jim Lattin, Len Lodish, Bob Meyer, and Don Morrison for their comments and suggestions.
