The organizational design literature strongly supports the notion of “structure follows strategy”, and suggests that a misfit between the two has a negative effect on performance. Building on this line of argument, we examine to what extent the (mis)fit between purchasing strategy and purchasing structure impacts purchasing performance. We focus on cost and innovation purchase category strategies, and examine how the deviation from an ideal purchasing structure defined along three dimensions (centralization, formalization, and cross-functionality) impacts purchasing performance. Analysing data collected from 469 firms in ten countries, we demonstrate that a strategy-structure misfit negatively impacts purchasing performance in both cost and innovation strategies. We also find that purchasing proficiency is a mediator in this relationship between misfit and performance. Our findings aid managerial decision making by empirically validating the necessity of having the right purchasing structure for successfully executing different purchasing strategies.  相似文献

We document a robust pattern of beta declining over the age of a firm. We find that changes in systematic risk via firm characteristics and life-cycle stages are insufficient to explain this pattern. Moreover, standard proxies for the quantity and quality of information also explain this pattern only partially. To fully explain this pattern we rely on the increasingly important role of familiarity in financial decision making: familiarity is a determinant of beta and firm age is a proxy for the degree of familiarity that investors feel toward individual stocks. To illustrate the implication of our findings, we document that when we control for firm age there is support for the CAPM and its use as an input for the cost of equity capital calculation.  相似文献

The main purpose of the study is to analyze the changing behavior of the customers on various products by conducting a customer review. The analysis is performed in three major steps such as, calculating customer review quality, calculating behavior quality of customer and review comparison. Behavioral analysis is a kind of science which helps to study and understand the behavior of human beings. It studies the factors that influence the behavior of living beings and non-living beings on a larger aspect. A special emphasis is placed on understanding, describing, predicting and changing behavior. Understanding the behavior of individuals is a tedious job to be performed and hence to evaluate the final result, the study used Chi-Square Method. As a tool, the paper employs customer reviews to gather primary and secondary data. These reviews inform, educate and explain the benefits of using customer reviews in gathering data. It is one of the best and easiest methods to formulate the score of comparison between customer's profile and their review. Findings of the study proved that depending on the customer's profile, the quality of the product varied. Furthermore, high rates of efficiency and accuracy is observed in gathering information on the products via customer's profile and review. Study authenticates an inclusive approach to explain factors manipulating consumer awareness, observation and sensitivity on product value. A depth analysis was carried out to identify the purchase decision, brand behavior, price influence the buying behavior and opinion of the customers. However, the factors such as high quality, social media networking sites and customer's profiles had a greater impact on buying behavior of the customers.  相似文献

文章基于2008-2017年制造业上市公司信贷数据,采用Dagum基尼系数、Kernel密度估计等方法实证考察了中国三大地区及四大行业群信贷配置的差距及其动态演进,并利用空间面板数据对信贷配置的时空收敛性进行检验。研究结果表明:(1)总体来看,中国信贷配置水平呈上升趋势,但信贷资金的地区配置和行业配置存在明显差距。(2)从地区角度,中国信贷配置总体差距、地区内差距和地区间差距均呈下降趋势,东部地区信贷配置较为均衡,未出现分化现象,中、西部地区的信贷配置在部分年份具有极化现象,且极化程度有所差异。具体来看,超变密度是总体差距的主要来源,各地区内省份之间信贷配置水平的非均衡性不断加强,地区内差距的贡献率逐渐上升,而地区间差距对总体差距的贡献率呈现下降的态势。(3)从行业角度,各行业群信贷配置差距的波动更加明显,呈现行业内差距和行业间差距演变趋势不一致的走向,其中资本投入拉动型行业群的内部差距呈扩大趋势,技术创新驱动型行业群的内部差距波动最大,劳动密集优势型行业群与技术创新驱动型行业群间差距最大。(4)此外,考虑时间和空间因素的收敛模型表明,在2008-2013年和2014-2017年两个样本时间段中,尽管中国信贷配置的时空收敛速度存在差距,但其时空收敛性是明显的,从经济进入新常态以来,外围区域向中心区域的追赶速度降低了。  相似文献

本文选取我国大陆31个省(市、自治区)2007年-2018年的面板数据,综合运用系统GMM和差分GMM估计方法,实证检验了沿海与内陆、沿边与非沿边、享受优惠政策高与低、金融控制强与弱等4类不同省区金融发展对经常项目余额的影响。研究结果表明:使用全部样本估计时,金融发展显著负向影响经常项目余额,这一结论经稳健性检验后依然成立。使用不同区域的子样本估计时,金融发展对沿海省区、非沿边省区、享受优惠政策高以及金融控制弱省区的经常项目余额的抑制作用较大,而在其他省区作用较小。因此,各地区应充分利用金融手段来调整进出口余额,以保证经常项目的持续平衡。  相似文献

This article analyses the overall profitability efficiency (PE) of Microfinance Institutions (MFIs) in Latin America. The PE of each MFI in the study is broken down into two components: pure technical efficiency and scale efficiency. One data envelopment model is used to analyse each component. Each MFI was labelled as either a bank, cooperative and credit union, nonbanking financial institution or non-governmental organization, and then the analysis was performed on each separate group. The results suggest that, on average, banks are the most efficient MFIs; while NGOs are, on average, the least efficient MFIs. On average, all 4 groups are more pure technically efficient than scale efficient. Banks, nongovernmental organizations, nonbanking financial institutions, cooperatives and credit unions all seem to have problems with scale efficiency. Many MFIs seem to be operating on the increasing returns to scale frontier and are in a more favourable position for expansion.  相似文献

It is documented in the literature that due to estimation errors, mean-variance efficient portfolios deliver no higher out-of-sample Sharpe ratios than does the naïve equally-weighted portfolio (EWP). This paper demonstrates how the out-of-sample performance of the minimum-variance portfolio (MVP) can be improved in the presence of estimation errors by combining the MVP and EWP. Our results indicate that an appropriate combination of the MVP and EWP can enhance Sharpe ratios under any scenarios considered, and can also reduce the portfolio risk if short-selling is allowed. However, the combination strategy is not able to generate a lower risk level than the MVP when a short-selling restriction is imposed. We find that the optimal combination coefficient depends on the factors that greatly impact estimation errors in the MVP, including sample size, estimation method, no-short-selling restriction, and length of the out-of-sample period under consideration.  相似文献
