Change within purchasing and supply management organisations – Assessing the claims from maturity models

It is a wide-held assumption that professional development and change within purchasing and supply management (PSM) organisations can be explained and guided by a maturity model. In this paper the guidance which the maturity model concept offers to understand a PSM organisation's performance is assessed. The methodology is based on the outcomes of a literature review of PSM maturity models, development of an organisational change framework and the learning from three qualitative case studies. An alternative understanding of the development of the PSM organisation is offered through an organisational change framework, composing 1) movement transitions, 2) scalability of change, 3) acceptability of change, and 4) the substantive element of change. The research found that extant PSM maturity models are too rigid for PSM managers to apply, and although maturity models are commonly accepted in PSM literature, in practice, they may produce the opposite effect of what is promised. The PSM maturity models suggest that their application will lead to increased status and influence of PSM within the organisation; expectations that may not be met. PSM organisations’ change processes are subjected to a range of situational and contextual power relations which must be considered in order to advance the specific PSM organisation roles and responsibilities.     

Firm age and performance

Amid increasing interest in firm age and its effects on firm performance, this special issue offers an exhaustive review of the literature and a novel collection of evidence on the effects of firm age on performance, including a special focus of interest on innovation performance, financial performance, exports, survival and growth. This editorial positions the theme in the extant literature, and provides key definitions and challenges ahead in the field of evolutionary economics. It introduces the collection of articles composing the special issue. The papers offer a diversity of country contexts, as well as analytical approaches and methods. They include an exhaustive review of the literature on age and firms’ performance, and present original empirical studies focusing on the effects of age on firms’ economic outcomes on the one hand, and on innovation outcomes on the other hand. While most of the papers use econometric analysis, the level of analysis ranges from firm to individual.     

Modelling purchases as a function of advertising and promotion

This article describes the preliminary studies of the effect of advertising and promotion on purchases. The British single-source database Adlab has been the basis for this study of advertising and promotion effectiveness. The ST AS measure and logit modelling have been used to estimate the effect of advertising. The results from the two measures have been compared to determine the extent to which the two measures give occasion for the same conclusions. To indicate the accuracy of the two measures, their respective levels of significance have been studied. Two logit models have been estimated; one only includes the effect of TV exposure, while the other also includes the effect of promotions. The results from the two logit models are compared to determine which model gives the most accurate estimate of the effect of advertising. When comparing the results from the STAS measure with the parameter estimates from the second logit model, it is found that these two different measures largely lead to similar conclusions. Suggestions for further research and developments of the models are given.

The Impact of Private Interest Contributions on RPS Adoption

In the last two decades, many U.S. states introduced policies to promote electricity generation from renewable energy sources (RES‐E). Renewable portfolio standards (RPS) are considered to be the key RES‐E policy tool to date. This article tackles the question on why some state legislators were front‐running the trend of RPS implementation whereas others adopted policies just recently, and why others have not adopted them at all. We compile data on financial contributions of conventional energy interest groups (CEI) and renewable energy interest groups (REI) to state‐level policy‐makers between 1998 and 2010. By means of hazard and tobit regressions, we test the effect of these financial contributions on the probability of RPS adoption and on RPS stringency. The article provides evidence in favor of interest group theory. First, CEI have donated more to state‐level legislators affiliated with the Republican Party than to Democrats while contributions from REI went largely to the latter. Second, there are statistically significant links between the likelihood of RPS adoption and private interest contributions. Contributions from CEI have a negative effect on the likelihood of RPS adoption whereas REI contributions have a positive effect.     

Gender-Based Focal Points

The subjects behaved significantly more “hawkish” in an experimental battle of the sexes game when the co-player was a woman compared to when it was a man. Discrimination helped the parties to coordinate and increase the average earnings in the subject group of mixed sex, compared to the unisex groups.

Freeing work from the constraints of location and time

Information technology makes possible working patterns with flexibility in location and time. But traditional assumptions of managerial control serve as a strong deterrent. This article deals with these issues through an analysis of interviews at ICL and Texaco UK, with managers and high-level employees who work partially at home. Rank Xerox networkers are used as a point of comparison .     

Creating value through mutual commitment to business network relationships

A structural model of business relationship development in a business network context is formulated and tested on data from the European International Marketing and Purchasing (IMP) project. The empirical analysis demonstrates a causal chain from business network connection through mutual commitment and mutual dependence to value creation in the relationship. The results show that mutuality in business network relationships is critical in developing interfirm systems of workflow interdependence that promote the creation of value. This also implies that, through their interaction in business network relationships, firms in business markets organize and share an unbounded structure of interdependent activities, enabling them to achieve greater value than would be the case if they did not engage in relationship development.

Consumer understanding of food labels: toward a generic tool for identifying the average consumer

The ‘average consumer’ is referred to as a standard in regulatory contexts when attempts are made to benchmark how consumers are expected to reason while decoding food labels. An attempt is made to operationalize this hypothetical ‘average consumer’ by proposing a tool for measuring the level of informedness of an individual consumer against the national median at any time. Informedness, i.e. the individual consumer's ability to interpret correctly the meaning of the words and signs on a food label is isolated as one essential dimension for dividing consumers into three groups: less-informed, informed, and highly informed consumers. Consumer informedness is assessed using a 60-question test related to information found on a variety of Danish everyday food products and divided into factual questions and informedness about signpost labels. A test was made with 407 respondents who participated in four independent studies on fairness in consumer communication, and the average score for all was 57.6% of correct answers. A score of 64% and beyond would place a consumer in the upper quartile (the group of highly informed consumers), whereas a score of 52% or below would place the individual in the lower quartile (the group of less-informed consumers). Female respondents performed better than males on label recognition, and those around 40 years of age irrespective of gender performed best on factual knowledge, whereas those aged around 30 performed best on label recognition. It is foreseen that independent future studies of consumer behavior and decision making in relation to food products in different contexts could benefit from this type of benchmarking tool.     

On the optimality of differentiated SPR tests of composite hypotheses

Summary It is shown that differentiated SPR tests, which are limiting cases of ordinary SPR tests, are asymptotically optimal in a decision-theoretic formulation for composite hypotheses in one-parameter problems. It is also given some results connected with comparisons of different tests in this case.
