Limits to creative destruction and technologies in practice: the case of ham radio

Drawing on the structurationist notion of ‘technologies-in-practice’, this article analyses the different types of technological actions that users perform, after technological change, in order to keep a declining technology alive over time. The research question of the article is: How do technologies-in-practice based on the application of new technology hamper the creative destruction of old technology? The case study of ham radio technology and amateur radio operators is explored. The results of the investigation support the development of a technology-in-practice ‘experimentation’ and four inductive research propositions.     

AHP-based approaches for supplier evaluation: Problems and perspectives

Supplier evaluation has assumed a strategic role in determining competitiveness of large manufacturing companies. An increasing number of researches have been devoted to the development of different kind of methodologies to cope with this problem. Nevertheless, while the number of applications is growing, there is little empirical evidence of the practical usefulness of such tools with a dichotomy between theoretical approaches and empirical applications. Considering this evidence, the goal of this paper is to contribute to understand the above dichotomy by implementing, in a corporate environment, a model for supplier evaluation based on the Analytical Hierarchical Process (AHP), one of the most prominent methodologies used to address the problem. The analysis of the implementation process of the methodology allows the identification of strengths and weaknesses of using formalized supplier selection models to tackle the supplier evaluation problem, also highlighting potential barriers preventing firms to adopt such methods. Relevant issues arising from the application and managerial implications for both customer and suppliers are discussed.     

A note on the Bourguignon–Fields class of poverty indices

Current poverty measurement methodology does not allow a definitive analysis of changes in distribution, through time or between countries, which involve changes in the number or proportion of poor people. By revisiting the continuity and transfer axioms, we show that within the Bourguignon and Fields (1997) class of poverty indices a range of value judgements can be accommodated as to what happens (or should happen) in the case that poverty-line crossings result from regressive transfers. In exposing this, we hope to provide empirical analysts with wider scope to use the Bourguignon–Fields poverty indices in an informed way.     

Interindustry differences in advertising in U.S. manufacturing: 1963–1977

Although there has been substantial research on the nature of the advertising-concentration relationship, there has been virtually no systematic investigation of the intertemporal stability of that relationship. The purpose of this study is not only to determine whether concentration has a linear or non-linear effect on advertising but also if this effect is stable over the 1963–1977 period. A consistent model and sample are maintained over the entire time period which eliminates the possibility that any differences in empirical results over time are due to differences in either the sample or model used in the analysis. The major findings are that the magnitude of the effect of concentration on advertising intensities has, in general, been stable over time and that the relationship has been quadratic in nature.

The precision of statistics of international migrations--a study of flows between Italy and the Federal Republic of Germany

The authors compare the quality of data concerning migration between Italy and the Federal Republic of Germany. Data are from the population registers of both countries. The analysis finds that German sources show migration levels between the two countries to be twice as high as do the Italian sources. Reasons for these discrepancies are discussed.     

Eliciting,Applying And Exploring Multidimensional Welfare Weights: Evidence From The Field

By combining primary data on dimension importance collected in the field from three different samples and nationally representative survey data from the Dominican Republic, we offer a twofold contribution. The first one comes from an unincentivized questionnaire experiment, where the significance of the treatment effect shows that life domains are valued differently in a poverty vs a well‐being framework. This poses important questions on the anatomy of dimension importance and on the use of weights in empirical analyses, and opens the door to what we call a “concordance paradox” related to the very essence of the constructs of poverty and well‐being. As a second contribution, we employ the sets of weights collected in the field to assess the trend of multidimensional poverty and well‐being in the country. We find that the picking one set of weights or another is not a trivial choice, as they lead to opposite assessment results.     

Relative Deprivation and School Enrolment. Evidence from Mexico

Using a large dataset (2.9 million households), we provide solid evidence of relative deprivation as being a negative correlate of school enrolment in Mexico, absolute standard of living being controlled for. This result is robust to a number of specifications, and to the use of linear and less than linear indices of relative deprivation. In addition, we find that marginal effects of relative deprivation are stronger at higher standards of living and for older children.

The Seminal Concept of Fast Expanding Markets

The circular pathway, also called the “cradle-to-cradle” model, is more than just recycling and environmental concerns. It is about a new way of thinking how we could grow without resorting to just expending resources. Its rapid expansion, as a new norm for companies, has characteristics of a Fast Expanding Market, given its exponential growth. In this article, we examine how the circular model is pushing companies and entities to come up with disruptive technology and business models that are based on longevity, renewability, reuse, repair, upgrade, refurbishment, servitization, capacity sharing and dematerialization. © 2015 Wiley Periodicals, Inc.
