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...
Article
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...

Article
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...
Article
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...

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...

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...

Article
Full-text available
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...
Article
Full-text available
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...

Full-text available
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...
Article
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...
Article
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...

This article proposes an explanation for the paradox of the polluting tertiarization.

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...

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...
