Mobilising supplier resources by being an attractive customer: Relevance,status and future research directions

For buying companies, supplier resource mobilisation is an essential process in gaining and sustaining preferential access to supplier resources. This editorial provides insights into the processes of supplier resource mobilisation and introduces three empirical studies on supplier resource mobilisation. We first introduce the supplier resource mobilisation cycle. This cycle may serve as a roadmap for purchasing and supply management (PSM) practitioners seeking to improve access to supplier resources. In addition, this article informs PSM scholars about the status of the supplier resource mobilisation literature and proposes avenues for future research. The cycle includes six stages: (1) becoming an attractive customer, (2) segmenting suppliers, (3) generating supplier satisfaction, (4) becoming a preferred customer, (5) engaging in supplier-oriented actions, and (6) integrating supplier resources. Finally, we introduce the articles in this issue that each examine a different stage of the supplier resource mobilisation process.     

Base stock policies with degraded service to larger orders

We study an inventory system controlled by a base stock policy assuming a compound renewal demand process. We extend the base stock policy by incorporating rules for degrading the service of larger orders. Two specific rules are considered, denoted as Postpone(q,t) and Split(q), respectively. The parameter q distinguishes between regular orders (of size less than or equal to q) and larger orders. We develop mathematical expressions for the performance measures: order fill rate of the regular orders and average on-hand inventory level. We make numerical experiments where the postpone parameter t and the base stock levels of each rule are such that all customers (of both order types) are indifferent between the two rules. When comparing the difference in the average on-hand inventory levels, we can then make an assessment of the threshold value of the cost of splitting an order (which may otherwise be hard to quantify) in the rule Split(q). Our numerical results indicate that this threshold value is increasing in the variance of the order sizes. Based on the numerical experiment our conclusion is therefore that when the variance of the order sizes is low, then Postpone(q,t) seems to be a good option, while when the variance is high, then Split(q) is more competitive.     

Smallholders' demand for and access to private‐sector extension services: A case study of contracted cotton producers in northern Tanzania

This paper examines demand for and access to private‐sector extension services by contracted cotton producers in northern Tanzania. Data from a non‐random survey of 520 smallholders show that only 21.9% received any extension and only 4.6% received extension from the cotton ginnery. Wealthier households were three times more likely to receive extension from any provider. While the public sector remains the main source of extension and is prioritized by smallholders, almost all households demanded extension from firms and are willing to invest 3 days per month mainly for advice on cotton and maize production. The involvement of third parties in the supply of extension from ginneries could not only meet smallholders' demands but could increase cotton supply and repayment rates to the firm, and thus finance the provision of missing extension advice.     

Flexible employment practices in Europe: country versus culture

Abstract This paper examines extent to which variances in flexible employment practices across fourteen European countries may be attributed to cultural variances. Data were gathered through a survey of human resource practices in 4,876 companies. The results indicate that national differences between flexible employment practices were explained by cultural differences. Specifically, we find use of part-time work is related to power distance and individualism; contract work is related to uncertainty avoidance and individualism; shift work is related to uncertainty avoidance, power distance and individualism; and telework is related to femininity.     

ICT-specific technological progress in the United Kingdom

This paper analyses the impact of rapid technological change in the information and communications technology (ICT) sector on economic growth in the United Kingdom. We find that technological progress specific to the ICT sector accounts for around 20–30% of long-run labor productivity growth. We demonstrate that a permanent increase in the growth rate of ICT-specific technological progress will increase the investment expenditure share of GDP but lower the aggregate depreciation rate, while an increase in the return to investment in ICT will increase both the expenditure share and the depreciation rate.     

A note on the existence of the power investor’s optimizer

Karatzas et al. (SIAM J. Control Optim. 29:707–730, 1991) ensure the existence of the expected utility maximizer for investors with constant relative risk aversion coefficients less than one. In this note, we explain a simple trick that allows us to use this result to provide the existence of utility maximizers for arbitrary coefficients of relative risk aversion. The simplicity of our approach is to be contrasted with the general existence result provided in Kramkov and Schachermayer (Ann. Appl. Probab. 9:904–950, 1999).     

Do Retail Foreign Direct Investment Restrictions Affect Retail Channel Structure?

The purpose of this study is to contribute to the existing retail channel structure research by investigating the impact of retail foreign direct investment (FDI) restrictions on retail channel structure as well as the moderating impact of a country's level of economic development on this relationship. Using a panel data set of 79 countries over the period 1999–2012, we show that retail FDI restrictions can influence retail channel structure development and that the relationship between retail FDI restrictions and retail channel structure is moderated by a country's level of economic development.     

Industry Interactions in Innovation Systems: A Bibliometric Study

Assorted interactions among the agents in a territory are considered as key elements for its scientific, technological, and innovation development, thus fostering the competitiveness of its business fabric and enhancing the quality of life of its residents. In this context, this article analyses this phenomenon, specifically industry relations with innovation system players (academic, scientific, technological, financing, and facilitating agents) through a bibliometric analysis. The methodology used progresses in three stages: construction of the scientific papers search strategy (published in the ISI Web of Knowledge reference database between 2001 and 2014); its implementation; and the corresponding bibliometric analysis, using the Vantage Point® software as a support tool. Among other aspects, the findings present progress achieved in the research field, together with leading authors, organizations, and countries, as well as with cooperative efforts among them, highlighting the status of this topic in Latin America. Finally, the article concludes that industry relations in innovation systems is a topic that is steadily expanding worldwide, with large numbers of cooperative projects among countries. However, it also shows that this study theme is still incipient in Latin America, not just Brazil.     

Consumer Rights: An Assessment of Justice

For the last 50 years the idea of consumer rights has formed an essential element in the formulation of policy to guide the workings of the marketplace. The extent and coverage of these rights has evolved and changed over time, yet there has been no comprehensive analysis as to the purpose and scope of consumer rights. In moral and ethical philosophy, rights are integrally linked to the notion of justice. By reassessing consumer rights through a justice-based framework, a number of key issues emerge regarding the way in which markets enable justice for consumers. The consumer rights which underpin the United Nations consumer protection guidelines address all forms of justice to some degree, but the predominant focus is on procedural justice. Our conclusions question whether this is sufficient and also whether there is a case to develop the notion of consumer ‘duties’ that complement the idea of rights.     

Using house prices to compute the price of housing in the CPI

Rental-equivalence is often used in computing price changes of owner-occupied housing in the CPI. We use an alternative approach, employing interest-adjusted house prices. For Norway 2000–2008 our method yielded a 30% CPI-increase, compared to the official 17%.
