The aim of this paper is to contribute to the debate on the usefulness of public libraries. Through a literature review, we document the shift in their core mission as they transition from codex curators to community builders. This reflects a change in service logic, moving away from the mobilization of technical capabilities in a low interactivity...

This chapter is devoted to an advocacy for innovation in services, which cannot be done without a more general advocacy in favor of services, insofar as it is impossible to dissociate the negative view of innovation in services from the negative view of services themselves. The supposedly deficient innovative capacity of services is just one of man...

Social entrepreneurship research remains largely conceptual and qualitative, which makes the comparisons with profit-seeking entrepreneurship difficult. This paper is an attempt to fill in this empirical divide. As such, we perform a statistical study of the characteristics of the social entrepreneurial city. Using a nationwide dataset on social ve...

This article is devoted to “public service innovation networks for social innovations” (PSINSIs) – collaborative systems that are being established, within public services, to design and implement social innovations. Drawing on a database of 24 case studies collected in different European countries and different areas of wicked social problems, thi...

This article is devoted to a new network form that is developing within the New Public Governance paradigm, namely “Public Service Innovation Networks” (PSINs). PSINs are multi-agent collaborative arrangements that develop within public service(s), spontaneously or at the instigation of local, national or European public policies. They mobilize a v...

Social innovations are often seen as the product of social entrepreneurs. This paper instead asserts that social innovations are also routinized. This is the result of the appearance of a new type of actors: Knowledge Intensive Social Services (KISS). Like Knowledge Intensive Business Services (KIBS), KISS are consultancy organizations that provide...

Literature on value co‐creation often postulates that a greater degree of co‐production increases the potential of value co‐creation. To test this hypothesis, we build a computational model of value proposition inspired by March’s model of organizational learning. The model allows us to represent various cases of co‐creation: (i) without coproducti...

This article is dedicated to a consideration of the tertiarization of innovation networks. While the concept of traditional innovation network has been the object of an extensive literature, new expressions of the innovation network appear in a service economy: in particular Public Private Innovation Networks in Services, Market Service Innovation...

The objective of this paper is to study the supply side of the silver market, which is usually neglected by research on this topic. Adopting a systemic approach to innovation, our main goals are to identify the nature of the innovations developed, the way innovations are created, and the issues related to their emergence and diffusion. Our research...

The paper presents a model of economic growth based on a population of heterogeneous and interacting agents. This model succeeds to generate - in a single framework - GDP growth and cycles as well as product life cycles. Contrary to the existing literature, we find that an increasing variety of consumer goods is not a necessary condition for sustai...

Gabriel Tarde est un auteur français que la sociologie redécouvre de manière récurrente. Les économistes de l’innovation se sont insuffisamment intéressés à un auteur qui a pourtant consacré une grande partie de son œuvre aux lois de l’imitation et de l’invention. L’objet de ce travail est triple. Il est, tout d’abord, de rendre compte, de manière...

The objective of this trial is to investigate the possibility, in feeding fattening rabbits under real production conditions, to reduce feeding costs by supplementing the commercial pellet feed with local green forage Sulla flexuosa orHedysarum flexuosum. In a growth trial, 80 rabbits of the local white population weaned at 35 days with an average...

Innovation is a condition for the survival of businesses, companies, territories, and nations. The concept of “open innovation” is used to review a number of key aspects of the innovation issue. This metaphor is used to try to report on the major contemporary openings made by experts in “innovation studies,” and in so doing, a number of important c...

Le concept de réseau d’innovation est un concept bien établi qui a fait l’objet d’une abondante littérature. Nous nous intéressons dans ce travail à des réseaux d’innovations particuliers, encore peu connus, mais qui se développent dans une économie de service dominante : les réseaux d’innovation public-privé dans les services (RIPPS). Les RIPPS dé...

The purpose of this work is to examine the extent to which services and service innovation can contribute to sustainable development in its environmental dimension. The supposed immateriality of services seems to argue in favour of their natural sustainability. This is actually just a myth – one we examine the roots of and which we refute. This cal...

Service innovation is a young but prolific research field, with a rapidly increasing number of publications being dedicated to the area. This new title provides a collection of the most significant articles that have helped build and develop this subject from a theoretical, empirical and methodological perspective. Together with an original introdu...

Notre question de recherche porte sur l’appréciation des performances de production et l’analyse de la « faible » commercialisation des produits de l’exploitation caprine (en particulier le lait). Seize exploitations caprines situées en zone montagneuse de Tizi-Ouzou ont été suivies pendant une année 2012-2013. Les résultats montrent que les élevag...

The aim of the present work is to study the effect of the season of birth and the sex on the growth of the lambs of the race Ouled Djellal before weaning. The survey is achieved with a strength of 30 lambs distributed in 2 independent shares; 15 born in the spring and 15 born in autumn. The data are collected with the help of the individual cards a...

Public-private innovation networks in services (PPINS) are a new expression of traditional innovation networks (INs) in contemporary service economies. There are a number of ways in which this new expression differs from the other. It differs from it, first of all, by its emphasis on market services and on public and non-market services in the dyna...

An important and highly debated question in economic geography is how to explain the dynamics of industrial clusters, i.e. their emergence and evolution through time. Two main theories are generally explored, without being confronted: the cluster life cycle theory-which mainly adopts an aggregate point of view-and the network-based approach. Althou...

The supposed immateriality of services seems to argue in favour of their natural sustainability. This is actually just a myth – one we examine the roots of, and which we refute. This ca...

Paradoxically, despite the extent of their contribution to wealth and employment, services are regularly blamed (in both political discourses and certain theoretical works) to be directly or indirectly responsible for the economic crisis. This short note aims at refuting such a paradox, arguing that the service economy is an economy of knowledge, s...

Ce papier a deux objectifs principaux. Il s’agit, tout d’abord, d’éclaircir, sous un angle essentiellement théorique, les liens existants entre les compétences dites dynamiques (celles qui traduisent la flexibilité de l’entreprise, sa capacité d’adaptation) et l’innovation. Il s’agit ensuite d’envisager, de façon plus concrète, la manière dont le m...

Gabriel Tarde was a French sociologist and criminologist whose work is rediscovered from time to time. Economists of innovation have paid insufficient attention to an author who devoted a large part of his work to the laws of imitation and invention. The purpose of this paper is threefold. The first is to give a succinct account of these laws of im...

Service innovation was neglected for a long time, but by the first years of this century it was clear that some maturity had been reached. Innovation in the public sector has been even more neglected in the mainstream of innovation studies. This paper explores the scope for fruitful integration of work on this topic into innovation studies more gen...

Contrary to a widely held prejudice, service activities are polluting because they make use of physical tools and require travel, both of which give rise to externalities. In order to deal with these externalities, service firms can implement eco-innovations. The aim of this article is to evaluate the sensitivity of this eco-innovation to environme...

The goal of this paper is to (re)assess the relationship between knowledge intensive business services (KIBS) and the economic growth. Taking into account various conflicting relationships between KIBS and growth, we build a multi agent-based system involving industrial firms, consumer-services firms, consumers, KIBS firms and a banking system. Our...

Does tertiarization foster the production of municipal waste ? The discussion of a paradox on the basis of a multi-agent model This article proposes an explanation for the paradox of the polluting tertiarization. We are particularly interested in the growth of municipal wastes which seems to follow the tertiarization process in developed economies....

ABSTRACT: In Algeria, the raising of the rabbit for meat develops more and more these last years. Several segments of this young sector have been studied as the feeding and reproduction. However, the segment of marketing has not been approached yet. This paper provides an overview of the rabbit meat marketing system in the Tizi-Ouzou area. To meet...

The concept of productivity is at the heart of economic theory, management science and operational management of firms and organizations. Despite the theoretical and operational importance of this concept, in recent years, its absolutism has been challenged. Services are often at the heart of this critical debate. Both conceptually and methodologic...

This article proposes an explanation for the paradox of the polluting tertiarization. We are particularly interested in the growth of municipal wastes which seems to follow the tertiarization process in developed economies. Relying on recent evolutionary works proposing a microfoundation of structural change based on the agents'adaptative behaviors...

This chapter is based on the analysis of two case studies in France (see Appendix for a description of the cases): a new advisory service for farmers based on satellite technologies (case FARMSTAR) and a new authentication and geo trace ability system for securing the environmental and organoleptic quality of wine (case GEOWINE). Thus, the cases de...

Social innovation and service innovation issues have developed separately over the last two decades, with too rare intersections between them. Both issues share many points in common, however, and sometimes even describe the same socio-economic reality. This contribution aims to help establish dialogue between these two still marginal but promising...

Innovation in Public Services After a long period of disregard and underestimation, the issue of innovation in services is now being taken seriously in economic theory, as well as in public policy. This is not yet the case for innovation in public services. The objective of this paper is to propose a re-interpretation of the literature on innovatio...

Innovation sociale et innovation de service Social innovation and service innovation issues have developed separately over the last two decades, with too rare intersections between them. Both issues share many points in common, however, and sometimes even describe the same socio-economic reality. This paper aims to help establishing a dialogue betw...

The concept of productivity is at the heart of economic theory, management science and operational management of firms and organizations. Despite the theoretical and operational importance of this concept, in recent years, its absolutism has been challenged. Services are often at the heart of this critical debate. Both conceptually and methodologic...

La question de la mesure et de l’amélioration de la productivité des services est récurrente dans les débats politiques, comme dans les travaux académiques, depuis plusieurs décennies. Le concept de productivité, qui a été élaboré initialement pour des économies industrielles et agricoles, pose peu de difficultés, lorsqu’on a affaire à des produits...

Le concept de réseau d'innovation est un concept bien établi qui a fait l'objet d'une abondante littérature théorique et empirique. Nous nous intéressons dans ce travail à des réseaux d'innovations particuliers, encore peu connus, mais qui se développent dans une économie de service dominante : les réseaux d'innovation public-privé dans les service...

Alors que dans le monde entier l’utilisation des ressources naturelles ne cesse de croître et l’environnement de se dégrader, les économistes,les managers et les politiques s’inquiètent avant tout de la perte de compétitivité de leurs entreprises et de leurs économies. Ils focalisent aussi leur attention sur les performances financières des système...

The aim of this article is to explain the overall shape of the waste stream of durable goods in the US economy. For this purpose we construct an agent-based model of economic growth and waste generation and compare this latter variable to the amount of waste of durables generated in the USA between 1960 and 2008. The model highlights a particularly...

Ce travail est consacré à l’analyse de la relation innovation-performance dans les économies développées contemporaines. Il met en évidence un double «gap » relatif à l’innovation et à la performance. L’« innovation gap » traduit la différence entre la réalité de l’innovation produite dans une économie et ce que les indicateurs traditionnels de l’i...

Résumé Contrairement à un préjugé fréquent, les prestations de service sont polluantes car elles mobilisent des outils matériels et nécessitent des déplacements, sources d'externalités. Pour faire face à ces exter-nalités, les entreprises de services peuvent mettre en oeuvre des éco-innovations. L'objectif de cet article est d'évaluer la sensibilit...

Productivity in its relationships with services raises two issues: a definition and measurement issue, on the one hand, and an issue related to the productivity strategies implemented, on the other hand. This article addresses both issues, focusing more on the latter. Our goal is to account for the various productivity strategies implemented within...

This special issue of the Journal of Innovation Economics is given over to services considered from the point of view of innovation and performance and against a background of sustainable development. Although contemporary economies are undeniably service economies, since services are now our main source of wealth and jobs, the relationship between...

The questions of innovation in services, on the one hand, and sustainable development , on the other, are relatively recent concerns for economic theorists and public policymakers alike. They have become key issues, which pose considerable academic, economic and political challenges. However, these two questions, and the problems they raise, have e...

This work is devoted to an analysis of the innovati on-performance relationship in contemporary developed economies. It reveals a doub le « gap » relating to innovation and performance. The « innovation gap » reflects the di fference between what traditional innovation indicators (R&D, patents) capture, and t he reality of innovation produced in an...

The concept of innovation network (IN) is a well-established one that has been the object of an extensive theoretical and empirical literature. Our subject in this paper is a particular kind of innovation network, as yet relatively unknown but which is developing against the background of economies dominated by service industries; we term them publ...

'The Handbook of Innovation and Services is an exceptional volume. Its contributors, including FaïGallouj, William Baumol, Jean Gadrey, and Pascal Petit, are among the major thinkers in both the fields of the economics of services and the economics of innovation. Selected topics include the "cost disease", services innovation in the global economy,...

Over the last decade, in France as in most Western economies, the employment and turnover of high-technology consultancy activities have shown two-digit growth rates. Consultancy in computer and communication technology in particular, as well as related management consultancy, have expanded to make France the second largest producer in the world of...

This work is devoted to an old question, but which faces a sharp renewed interest: productivity in its relationship with public services. Public services constitute a particularly difficult challenge for productivity (its definition, its evaluation, but also its strategic implementation), insofar as they add to the traditional difficulties induced...

Feed autonomy is appreciated on the level of 6 exploitations with 261 cows, by calculating the proportion of feed produced (forage and concentrate) on the exploitation compared to those consumed. It is declined according to the nature of feed (forage, concentrate) and according to their composition (total dry matter, energy value (UFL), proteins (M...

This paper examines the question of innovation in a particular group of services, namely 'assembled' services, such as hotels, retailing and distribution, hospitals, theme parks, etc. These are complex services produced by combining a variable number of other constituent services. Drawing on findings from the economics of services and the economics...
