Do monetary subjective well-being evaluations vary across space? Comparing continuous and discrete spatial heterogeneity

Using subjective well-being estimations, this study analyzes whether compensating variations vary across space using a cross-sectional data set from Chile. To achieve this goal, it describes and compares two econometric ways of modelling unobserved spatial heterogeneity. Both approaches allow compensating variations to vary across spatial units by assuming some distribution a priori. One method assumes that the spatial heterogeneity can be represented by a discrete distribution (a group of regions that share the same coefficient) and the other that the preferences can be represented by a continuous distribution (each region has a different coefficient). The results show that focusing just on the average estimates of compensating variations, as the applied studies have done so far, masks useful local variation. More empirical studies are needed to assess the advantages and disadvantages of both econometric approaches and how their results compare across a wide range of conditions and samples.     

中国大中城市商业地产开发环境评价——基于时序全局主成分分析

2007年爆发的金融危机不但改变了全球经济格局,也增加了中国房地产市场的不确定性因素。随着住宅开发的竞争越来越激烈,其利润率呈现走低趋势。越来越多的房地产开发商从住宅地产转向商业地产领域,以期获得更加丰厚的回报。选取中国35个大中城市的42个变量共计近6000个数据,利用时序全局主成分分析法对后金融危机时期的这些城市商业地产开发环境进行了系统研究,建立了比较科学的评价指标体系。     

管理学视角下知行难易关系之辨

＂知＂和＂行＂是一对重要的哲学范畴,知行难易关系众说纷纭。文中根据现代管理学权变理论和沟通原理,重新解读傅说＂知易行难＂说、程颐＂行难知亦难＂说、孙中山＂知难行易＂说和胡适＂知难行亦不易＂说,并提出先贤们各不相同的知行难易学说,是基于沟通对象不同、方向不同、目的不同的主旨思想。

THE BIAS OF THE MULTIPLIER MATRIX WHEN SUPPLY AND USE TABLES ARE STOCHASTIC

The literature on stochastic input–output (I–O) analysis has paid considerable attention to the bias in the Leontief inverse. This paper extends previous studies by assuming supply and use tables (SUTs rather than I–O tables or input coefficients matrices) to be stochastic. This is a natural starting point because SUTs have become the basic data sources for I–O applications. In a Monte Carlo simulation experiment, a given SUT is randomized in two different ways and the effects are determined for eight different multiplier matrices. The analysis is carried out for Spain, Italy, the Netherlands, Germany and Finland, using their SUTs for 2006. The findings indicate that, in general, biases are statistically significant but negligibly small. This corroborates earlier findings obtained for stochastic I–O tables.     

Improving the Sustainable Development of Firms: The Role of Employees

Stakeholders have been found to be an important driver of organizations' sustainable development. In particular, customers, governments and non‐governmental organizations push firms towards sustainability. But to what extent is sustainability really and deeply embedded within an organization's structures and processes? And what is the role of an important, but frequently neglected, stakeholder group for successful sustainability implementation: employees? The objective of this research is to better understand the impact that organizational change for sustainability has on firm performance. Also, this study seeks to understand how the consideration of employees into the process of organizational change for sustainability moderates the organizational change and performance relationship. Using data from 92 German companies from the manufacturing and services sector, the study finds that the structural implementation of sustainability is positively related to firm performance and that employee integration moderates this relationship to some extent.

On the relationship between supplier integration and time-to-market

Recent operations management and innovation management research emphasizes the importance of supplier integration. However, the empirical results as to the relationship between supplier integration and time-to-market are ambivalent. To understand this important relationship, we incorporate two major recent developments. First, the literature has started to redefine supplier integration into two dimensions, supplier product integration and supplier process integration. Second, recent research has begun to examine spillover effects that extend beyond the direct costs and benefits of the supplier contract. Using survey data of 116 firms in the industrials, health care, and information technology industries, the results confirm our hypotheses and show that supplier product integration decelerates time-to-market while supplier process integration accelerates time-to-market. The results also show a positive relationship between supplier integration and the adoption of external technologies, which either decelerates or accelerates time-to-market depending on the level of internal exploration activities. Our research, thus, helps to open the ‘black-box’ of the relationship between supplier integration and time-to-market, and provides a theoretically grounded explanation to the apparent contradictory results in prior research about the influence of supplier integration on time-to-market. In addition, we contribute to research on spillover effects by emphasizing that information technology adoption and assimilation is an important spillover effect of supplier integration.     

城乡关系变迁的新动力——基于城乡复合型二元结构视角的分析

在市郊农村,由于在原有城乡二元结构基础上嵌入了新的一元——外来移民,产生了原住民(主要是当地农民)与外来移民(主要是流动民工)之间的新二元差别,从而形成了当代中国城乡关系中特有的一种新型二元结构——复合型二元结构。这种新型二元结构一方面由于其普遍性和梯度型非连续分布,在现时期呈现出阶段性、长期性的特征,另一方面由于其流动性、动态性、非稳定性的属性,在我国的社会主义新农村建设中往往被忽略。尝试借助复合型二元结构概念分析城乡关系问题,揭示城乡关系变迁的新动力。     

欧美城市贫困集中研究述评及对我国的启示

从城市地理学、城市规划学和城市社会学的视角,综合评述了欧美国家城市贫困集中的现象,分析了贫困集中所造成的居民收入和就业机会下降、社会隔离及歧视加剧、社会治安环境恶劣、孩子遭受不良影响和公共配套设施短缺等问题,探究了市场、政府、特殊人文因素和产业结构转型等因素对贫困集中的影响。欧美城市经验为我国城市发展提供了有价值的启示,为了减少贫困集中以及由此引发的社会问题,政府应主动进行调控,缩小居民过大的收入差距,避免经济适用房和廉租房住区的集中布局,建设多样化混合社区,以及使公共住房政策由供给导向向需求导向转变。
