Career Patterns of Supply Chain Executives: An Optimal Matching Analysis

This exploratory study analyzes the careers of 307 supply chain executives (SCEs). Motivated by career theory, our findings create new knowledge about the educational backgrounds and career paths that lead to SCE positions. Based on an optimal matching analysis, we are able to distinguish among six career patterns for SCEs. They differ in terms of the individuals’ previous professional experience, educational background, and the time they needed to arrive in an executive position. By characterizing the backgrounds and career paths of SCEs, we show that supply chain management (SCM) is truly a cross‐functional profession. Our findings suggest that previous staff responsibility appears to be a more important hiring criterion than extensive SCM experience. While 56% of the executives had prior staff responsibility, only 12% of the cumulated careers were actually spent inside the SCM function.     

Modeling the Factors Affecting Organic or Local Cucumber Purchasing Motivations in Northern Iran

This article has attempted to examine the impact of motivation on the purchasing and represents a model for organic or local cucumbers buying dimensions. Data were collected by a sample of 300 people in two northern provinces of Iran during 7 months and were tested using structural equation modeling (SEM) technique. Results indicate that not using pesticides, preserving people’s health, conservation, better taste, and region of origin of organic or local cucumbers have significant positive impacts on purchasing dimensions and persistence has no significant effect on purchasing dimensions.

The impact of relative residence times on the distribution of heavy drinkers in highly distinct environments

Alcohol consumption is a function of social dynamics, environmental contexts, individuals' preferences and family history. Empirical surveys have focused primarily on identification of risk factors for high-level drinking but have done little to clarify the underlying mechanisms at work. Also, there have been few attempts to apply nonlinear dynamics to the study of these mechanisms and processes at the population level. A simple framework where drinking is modeled as a socially contagious process in low- and high-risk connected environments is introduced. Individuals are classified as light, moderate (assumed mobile), and heavy drinkers. Moderate drinkers provide the link between both environments, that is, they are assumed to be the only individuals drinking in both settings. The focus here is on the effect of moderate drinkers, measured by the proportion of their time spent in “low-” versus “high-” risk drinking environments, on the distribution of drinkers.A simple model within our contact framework predicts that if the relative residence times of moderate drinkers are distributed randomly between low- and high-risk environments then the proportion of heavy drinkers is likely to be higher than expected. However, the full story even in a highly simplified setting is not so simple because “strong” local social mixing tends to increase high-risk drinking on its own. High levels of social interaction between light and moderate drinkers in low-risk environments can diminish the importance of the distribution of relative drinking times on the prevalence of heavy drinking.     

The influence of website quality dimensions on e-purchasing behaviour and e-loyalty: a comparative study of Egyptian travel agents and hotels

Websites have become a channel for tourism enterprises to market and sell their services online. These enterprises are committed to improving their online services to retain customers and improving their competitiveness. This study aims to measure the effect of website quality dimensions on customer purchasing behaviour, and how this behaviour affects customer electronic (e)-loyalty. It compares the perceptions of 275 customers of travel agencies and 355 hotels using structural equation modelling. Findings revealed that website quality dimensions significantly affect the customer purchasing behaviour. The study highlighted the dimensions with a negative effect to help managers improve their website quality.     

论我国西部区域间经济发展格局的变动

西部大开发的10年中,西部各地区都取得了巨大的发展成就,但彼此间的发展进度并不一致,导致了经济发展格局的变动。经过数据分析发现,西部各区域间发展差距有扩大的趋势,并且经济发展重心也有较大变化。认真分析这一变化,对于因地制宜的制定区域发展政策,促进区域协调发展具有重要指导意义。     

Money Allocation to Out-of-Home Leisure Activities and the Organization of These Activities in Time and Space

Monetary budgets influence activity participation and related travel as they demarcate limits on how people organize their activities in time and space. In this paper, we are interested in money allocation to out-of-home leisure activities and how this is affected by duration, sociodemographics, and time-location variables. Analyses were carried out by applying a seemingly unrelated regression model to a leisure activity data set. The analyses revealed that expenditures for out-of-home leisure activities are influenced by the variables mentioned above. Moreover, the results indicate that there is a substitution between expenditure of each activity.     

政府采购中寻租行为的经济学分析

政府采购中项目剩余和信息不对称的存在,加之市场发育不完善,导致寻租行为的产生。公开交易信息,加大寻租成本,建立事前监督、事后惩罚制度,是遏制寻租行为产生的重要手段。     

人民币购买力平价成立吗?——基于人民币兑欧元的多样本协整分析

选取人民币兑非主权国家货币——欧元的名义汇率,中国CPI指数及欧元区调和HICP指数的数据,以欧元正式成为欧元区唯一合法货币的起点2002年7月到2018年12月为样本,依据影响中欧汇率的重要节点事件对样本进行分段与结合,对人民币兑欧元购买力平价(PPP)成立与否进行协整检验。实证结论有:人民币汇率形成制度改革及欧元平稳运行后的(2005年8月—2018年12月)人民币兑欧元购买力平价协整检验成立;非主权国家货币欧元同样适用经典的购买力平价理论;2008年金融危机是影响汇率市场的重要节点事件,但长期不影响人民币兑欧元购买力平价成立;对PPP冲击影响最大的首先是汇率本身,其次依次是欧元区HICP、中国CPI。因此,购买力平价在一定程度上能够解释人民币兑欧元汇率,对中欧经贸往来有一定的指导作用。     

劳动要素报酬、人口结构与中国居民储蓄

以动态一般均衡模型为出发点,分析劳动要素报酬、人口结构对居民储蓄率的影响,并运用中国1978～2009年的数据对劳动要素报酬、老人赡养比、儿童抚养比与中国居民储蓄率进行实证检验。研究发现,市场经济转型以来的劳动要素报酬高速增长、老人赡养比上升以及儿童抚养比的下降导致中国储蓄率不断升高,在此基础上给出相应的政策建议。
