Using replication research for just-in-time purchasing construct development

Using replication research, the validity of the just-in-time purchasing (JITP) construct is established. Although empirical researchers have examined JITP over the last two decades, a consistent set of valid, reliable factors has not been used. The lack of valid construct is a barrier to hypotheses testing and meta-analyses on JITP. This study confirmed the validity of six JITP factors: top management commitment, employee relations, training, supplier quality management, transportation, and quantities delivered using two different data sets and testing the first- and second-order structure of the JITP construct. Content validity, reliability, unidimensionality, convergent validity, discriminant validity, criterion-related validity, and an invariant factorial structure of the JITP construct were empirically established.

Understanding supplier structural embeddedness: A social network perspective

Despite a significant amount of attention, the potential of supplier structural embeddedness (i.e., the value of the structural position in an extended network) to improve the performance of a buying firm remains poorly understood. This study drew on the social network theory to empirically examine a conceptual framework specifying a relationship between the efforts of a buying firm to understand supplier structural configuration and operational and financial performance. This study also examines how the comprehension of structural embeddedness is transformed into performance for a buying firm through relational embeddedness (i.e., the strength of a dyadic relationship). Survey data collected from companies in the U.S. were analyzed using hierarchical regression analysis. The results indicate that the understanding of the structural dimension does help to enhance operational performance of a buying firm, but it does not lead to better financial performance. Empirical evidence shows that a buying firm does improve the quality of a dyadic relationship between the buying firm and a supplier by understanding how the supplier is connected to other firms and what positional values are produced. Further, relational embeddedness is found to mediate the influence of the enhanced understanding of the structural configuration on operational performance.     

Supply structure: The pendulum in action

Using an in-depth longitudinal case study based on an “historical retrospective”, this article focuses on how some factors (“drivers”) set into motion the pendulum of change in supply structures, a research theme neglected in the supply field. It examines, over a 20-year period, the changes made to the supply structure of a well-known organization. The data comes mainly from: (a) semi-structured interviews with 21 managers and professionals within eight operating units, and (b) documentary analyses of the archives. This article shows how to map structural changes of the supply function, while explaining the nature and the causes of these changes. Understanding the pendulum movement from one supply structure to another can be very valuable, as well for academics as for managers.     

生别调解下高卷入产品品牌体验对品牌忠诚的影响

顾客的品牌体验会影响品牌忠诚,在现有文献中已基本达成其识。本文基于进一步的维度划分,研究了品牌体验五个维度对品牌忠诚两个维度的不同影响,尤其检验了性别差异的调解作用。构建了以品牌体验为自变量,品牌忠诚为因变量,性别为调节变量的结构方程模型,进行实证研究。结果表明：品牌体验各维度对品牌忠诚的影响有不同,并且性别差异的调解效应显著。并提出企业应根据不同的目标顾客群,以不同的体验维度为重点构建品牌忠诚。从一个新的视角为品牌忠诚构建提供了理论指导。     

COEFFICIENT CHANGE,PRICE EFFECTS,AND IMPLICIT ELASTICITIES: ESTIMATING MICROECONOMIC DETERMINANTS OVER TWO TIME PERIODS

This paper presents and estimates an input–output model in which input coefficient changes are functions of changing prices. The model produces results that mirror the characteristics of input demand functions based on the model of cost minimization subject to producing a desired level of output. It does not rely on the specification of a functional form for input coefficients, and it does not require the use of assumptions regarding the elasticity of substitution. Instead, it allows the actual price and coefficient changes that occur between periods to identify the implicit elasticities and own- and cross-price derivatives. Using this model, it is shown how accurate measures of price effects, including the full array of own and cross-elasticities of demand, can be estimated for models comprising up to 15 sectors given data for only two time periods.     

Test of the MBA knowledge and skills transfer

In view of the growing popularity of the MBA degree as a management development tool, there is a need to examine knowledge and skills transfer among MBA graduates. This study then developed and tested a parsimonious model of perceived transfer of knowledge and skills of MBA graduates to the job. Respondents were those who had completed part-time MBA programmes in Hong Kong for at least one year but not more than five years. LISREL results revealed a modest fit of the model to the data. The path coefficients further revealed that seven of the fifteen predicted relationships were statistically significant and in the predicted direction. Specifically, self-efficacy, Type A personality, transfer climate, and transfer rewards were positively related to motivation to learn, while organizational commitment was negatively related to motivation to learn. The results also indicated that motivation to learn, continuous-learning culture, and utility of MBA programme were positively related to perceived knowledge and skills transfer.     

MIND THE GAP: UNEMPLOYMENT IN THE NEW EU REGIONS

Abstract.  The paper surveys the theoretical and empirical literature on regional unemployment during transition in Central and Eastern Europe. The focus is on optimal speed of transition (OST) models and on comparison of them with the neo-classical tradition. In the typical neo-classical models, spatial differences essentially arise as a consequence of supply side constraints and institutional rigidities. Slow-growth, high-unemployment regions are those with backward economic structures and constraints on factors mobility contribute to making differences persistent. However, such explanations leave the question unanswered of how unemployment differences arise in the first place. Economic transition provides an excellent testing ground to answer this question. Pre-figuring an empirical law, the OST literature finds that the high degree of labour turnover of high unemployment regions is associated with a high rate of industrial restructuring and, consequently, that low unemployment may be achieved by implementing transition more gradually. Moreover, international trade, foreign direct investment and various agglomeration factors help explain the success of capital cities compared to peripheral towns and rural areas in achieving low unemployment. The evidence of the empirical literature on supply side factors suggests that wage flexibility in Central and Eastern Europe is not lower than in other EU countries, while labour mobility seems to reinforce rather than change the spatial pattern of unemployment.     

Propensity to firm creation: empirical research using structural equations

The identification of the entrepreneurs’ characteristics and the knowledge of the entrepreneurial profile of university students have been assuming a growing importance in the development of educational programs directed towards the entrepreneurship and start-up processes. This study aims to identify the factors that most contribute for the intention to start up a business. The research also tries to identify the profile of a potential entrepreneur student concerning several characteristics: personal attributes, family, demographic variables and motivations. Research findings include the idea that entrepreneurship education is the most relevant factor in what concerns the propensity to business creation. On the other side, personal characteristics have an important role in shaping motivation to start-up a business and perceived hurdles have a negative impact in the intention to start-up. The results may be relevant when developing an adequate educational program directed to the entrepreneurship education and start-up processes.     

Forecasting government support in Irish general elections: Opinion polls and structural models

Election forecasting is a cottage industry among pollsters, the media, political scientists, and political anoraks. Here, we plow a fresh field in providing a systematic exploration of election forecasting in Ireland. We develop a structural forecast model for predicting incumbent government support in Irish general elections between 1977 and 2020 (the Iowa model). We contrast this structural model with forecasts from opinion polls, the dominant means of predicting Ireland’s elections to date. Our results show that with appropriate lead-in time, structural models perform similarly to opinion polls in predicting government support when the dependent variable is vote share. Most importantly, however, the Iowa model is superior to opinion polls in predicting government seat share, the ultimate decider of government fate in parliamentary systems, and especially significant in single transferable vote (STV) systems where vote and seat shares are not always in sync. Our results provide cumulative evidence of the potency of structural electoral forecast models globally, with the takeaway that the Iowa model estimating seat share outpaces other prediction approaches in anticipating government performance in Irish general elections.
