The Fair Trade Idea: Towards an Economics of Social Labels

The concept of Fair Trade is applied to the marketing of a variety of goods. In recent years it has met a continually increasing interest among consumers. Different Fair Trade organizations are trying to accomplish an improvement in working and living conditions in developing countries by means of Fair Trade certificates and by paying a price markedly above world market standard. This is meant to lead to the attainment of basic social standards, especially in agricultural production. The article deals with how Fair Trade works and whether the social aims can be achieved by the application of this trade concept. Our main result is that even though efficiency of redistribution through the Fair Trade institutions is lower than through traditional relief organizations, the Fair Trade concept provides an additional incentive to support better living conditions in the Third World. Moreover, it provides a stimulus for producers to reorganize the production process in a socially more acceptable manner even when this is not rewarded by the Fair Trade company.

Financial fairness and conditional indexation

Collective pension contracts can generate advantages for their participants by implementing forms of risk sharing. To ensure the continuity of a collective scheme, it has to be monitored whether the contracts offered to participants are financially fair in terms of their market value. When risk sharing is implemented by means of optionalities such as conditional indexation, the analysis of financial fairness is not straightforward. In this paper, we use a stylised overlapping generations model to study financial fairness for a conditional indexation scheme. We find that financial fairness for all participants at all times is not feasible within a scheme of this type, unless the nature of indexation is such that the scheme is reduced to DC. However, financial fairness for incoming generations at the moment of entry can be realised. We show how to compute the fair contribution rate as a function of the current nominal asset/liability ratio for a given level of nominal entitlements. At low levels of the ratio, the fair contribution for incoming generations is also relatively low; nevertheless, the joining of a new generation still has a positive effect on the asset/liability ratio.     

Zur Verteilung der Abschlusskosten in deutschen Lebensversicherungen

It will be shown that an amortization spread of the acquisition costs to the first N years of a classical german life insurance policy or lifelong annuity always leads to a non negative technical provision at the end of the first year if \( N\,{=}\,5 \) (and the technical provision starting with zero). For usual combinations of the age at entry and the policy duration even \( N\,{=}\,3 \) is sufficient for this purpose. The legal specification given by the new version of VVG in Germany concerning surrender value (i.e. positive value even in case of early lapse) is therefore consistent with the requirement of a amortization spread to 5 years. Additionally a recursion formula for the technical provision with N years spreaded acquisition costs is proven.

Understanding the Antecedents,Contingencies, and Performance Implications of Process Innovation: A Dynamic Capabilities Perspective

This paper examines one of the most important sources of competitiveness in dynamic industries—the capability of firms to introduce process innovations. While the management of product innovation has received considerable theoretical and empirical attention in the literature, our knowledge about how firms become process innovators—and why many firms fail to do so—remains underdeveloped. In order to provide novel insights into the configuration of firms' process innovation activities and their performance implications, this paper draws on the dynamic capabilities approach. More specifically, this study aims to shed light on the antecedents, contingencies, and performance consequences of interfirm differences in process innovation success, that is, firms' propensity and effectiveness of implementing new production, supply chain, or administrative processes. Particular emphasis is placed upon the analysis of potential complementarities or substitution effects between innovation activities such as internal and external research and development, prototyping, external knowledge acquisition, and employee training. Cross‐sectional data from a large‐scale survey of German manufacturing and service firms serves as the basis for testing the hypotheses advanced in this paper. Findings suggest that by engaging in a broad range of different innovation activities, firms can indeed increase the likelihood of achieving process innovation success, which is in turn positively related to firm financial performance. Yet decreasing marginal returns to innovation activities have to be considered as process innovation propensity was found to increase with the number of activities pursued simultaneously only up to a point, after which negative marginal returns set in (inverted U‐shaped relationship). Furthermore, while environmental turbulence was found to have surprisingly little influence when it comes to translating process innovation success into firms' subsequent financial performance, industry membership as well as the nature of the innovation process (i.e., internal generation, external adoption, or cocreation of an innovation) emerged as key contingency factors. These findings have important theoretical as well as practical implications for managing new process introductions.     

Impacts of mobile Internet use intensity on the demand for SMS and voice services of mobile network operators: An empirical multi-method study of German mobile Internet customers

Scholarly and business publications alike convey the message that past and future strong growth in mobile Internet (MI) access and service demand has solely positive commercial implications for mobile network operators (MNOs). This position neglects the possibility that increasing MI use intensity may lead to demand decreases for the highly profitable short messaging service (SMS) and mobile voice telephony. The extant literature provides few insights on relations between MI use intensity, on the one hand, and SMS as well as mobile voice call use intensities, on the other hand. This study developed hypotheses concerning the presence or absence of impacts of MI use intensity and circumstances of MI use (e.g., device type, tariff scheme) on the demand for SMS and mobile voice telephony at the individual customer level. The hypotheses were tested by analyzing actual use behaviors of 304 MI adopters in Germany, for whom objective use intensity data were extracted from the billing system of an MNO. These non-reactive measures were combined with responses collected from the adopters through a telephone survey. Multivariate regression results suggest that though MI use intensity significantly negatively affected both number of SMS sent and received, these effects were so small that their practical relevance is highly doubtful. Further, customers who used MI more intensively did not generate lower volumes of outgoing or incoming mobile voice connection minutes. Conclusions are drawn for MNO, telecommunications sector regulators and scholarly researchers seeking to explain the acceptance of mobile communications services.     

Creating shareholder value via collaborative innovation: the role of industry and resource alignment in knowledge exploration

Collaborative innovation provides firms with a privileged opportunity to perform exploration in an externally oriented mode. The central challenges in exploration via collaborative innovation lie in the selection of relevant partners and in gaining access to potentially valuable external knowledge that the focal firm lacks. This article focuses on two aspects of inter-organizational alignment that affect knowledge differences and may thus help explaining the shareholder value implications arising from collaborative innovation: industry and resource alignment. Relying on data covering 97 bilateral collaborative innovations (194 innovation partners) in R&D intensive high-technology industries, we used event study methodology and follow-up hierarchical regression analyses to test our conceptual framework. With regard to industry alignment, results suggest that investors value greater industry distance between collaborating partners, especially when the partner firm provides high-level R&D resources. Furthermore, the results show a positive effect of supplementary resource alignment (i.e., a focal firm's R&D resources are supplemented by a partner firm's R&D resources) and, notably, a negative effect of complementary resource alignment (i.e., a focal firm's R&D resources are complemented by a partner firm's marketing resources) on investors' valuation of the collaboration's expected future performance. They, thus, contribute to research on shareholder value implications of collaborative innovation. From a managerial perspective, the study provides a better understanding of partner selection and shows how managers should position a collaboration to signal the shareholder value-creating potential to investors.     

Mapping the Topic Landscape of JPIM, 1984–2013: In Search of Hidden Structures and Development Trajectories

During the three decades since its inception in 1984, the JPIM has shaped the evolution of innovation research as a scientific field. It helped create a topic landscape that is not only more diverse and rich in insights, but also more complex and fragmented in structure than ever before. We seek to map this landscape and identify salient development trajectories over time. In contrast to prior citation‐based studies covering the first two decades of JPIM research, we benefit from recent advances in natural language processing and rely on a topic modeling algorithm to extract 57 distinct topics and the corresponding most common words, terms, and phrases from the entire full‐text corpus of 1008 JPIM articles published between 1984 and 2013. Estimating the development trajectory of each topic based on yearly publication counts in JPIM allows us to identify “hot,” “cold,” “revival,” “evergreen,” and “wall‐flower” topics. We map these topics onto the Product Development and Management Association (PDMA) Body of Knowledge categories and discover that these categories differ significantly not only in terms of their internal topic diversity and relative prevalence, but also—and arguably more importantly—in terms of their publication and citation trajectories over time. For instance, the PDMA category “Codevelopment and Alliances” exhibits only moderate topic diversity (7 out of 57 topics) and prevalence in JPIM (161 out of 1008 articles). That said, it is among the most dynamic categories featuring two evergreen topic (“Users and Innovation” and “Tools and Systems for Technology Transfer”) and three hot topics (“Open Innovation,” “Alliances and Cooperation,” and “Networks and Network Structure”) as well as a sharply growing annual number of citations received. Our findings are likely to be of interest to all those who are keen to (re)discover JPIM's topic landscape in search of hidden structures and development trajectories.
