Critical study of the quantity theory of money in the history of prices crisis
2014
The Quantity Theory of money which always links the increase in the high-Powered money supply and the general rise in prices is one of the oldest concepts in economics. After to have been the subject of many controversies at different times, it seems nowadays to hold less attention from the economists because the dispute is dissipated in a kind of religious choice to believe or not to believe to quantity theory. This theory officially influences the monetary policy of most of central banks in the world that bind conventional measures to control the money supply to curb inflation process. In many orthodox economics’ textbooks, the quantity theory is still deployed in perpetuum to explain the…
Étude d’une pépinière créative : enseignements issus de la théorie de la proximité
2016
International audience; Cette communication s’intéresse au fonctionnement des pépinières créatives créées à l’initiative des pouvoirs publics. Développées sur le concept de proximité, celles-ci visent à favoriser les interconnexions entre les activités dans un même espace pour augmenter la capacité créative. Nous étudions le cas du Mixeur à Saint-Etienne, à partir d’entretiens auprès des acteurs publics en charge du projet et d’entrepreneurs de la pépinière créative. Nous cherchons à comprendre quels types de proximités sont mobilisés pour alimenter l’innovation dans une pépinière créative. Adoptant une approche qualitative, nous nous demandons en quoi la proximité est-elle un levier de dév…
La crise inscrit-elle les jeunes en France dans une dynamique de gagnants-perdants ?
2016
International audience; L'entrée des jeunes dans la vie active est particulièrement sensible aux aléas conjoncturels. L'objet de cette communication est d'appréhender les conséquences de la crise financière de 2008 sur les premières années de vie active des jeunes en mobilisant la théorie de la segmentation du marché du travail formulée par Doeringer et Piore (1971). Dans le sens de cette théorie, les emplois précaires ou instables seraient davantage l'apanage des jeunes en début de vie professionnelle. Mais qu'en est-il en temps de crise ? S'agit-il d'un point de passage plus ou moins inévitable pour toutes et tous, ou l'emploi précaire demeure-t-il pour une main-d'oeuvre captive tels les …
On some aspects of Borel-Moore homology in motivic homotopy : weight and Quillen’s G-theory
2016
The theme of this thesis is different aspects of Borel-Moore theory in the world of motives. Classically, over the field of complex numbers, Borel-Moore homology, also called “homology with compact support”, has some properties quite different from singular homology. In this thesis we study some generalizations and applications of this theory in triangulated categories of motives.The thesis is composed of two parts. In the first part we define Borel-Moore motivic homology in the triangulated categories of mixed motives defined by Cisinski and Déglise and study its various functorial properties, especially a functoriality similar to the refined Gysin morphism defined by Fulton. These results…
Le marché du travail des scientifiques : capital humain, incitations, proximité
2011
The aim of that thesis is to bring a micro level contribution to the economics of innovation when using original datasets on the French case. Here the manuscript is structured in three chapters: the labour market of scientists and engineers, the incentives for innovation in the private sector and the existence of spatial spillovers in the school to work transition for graduates in science and engineering (S & I). In the first chapter of this thesis, we focus on the labour market for scientists and engineers. First, we identify the different characteristics of this labour market. We then analyze the determinants of access to R & D for young graduates in S & I. Finally, we question more broad…

Prevention of occupational injuries moral hazard and complex agency relationship
2001
This paper exploits the results of agency theory with the aim of contributing a new viewpoint and a form for analysis of the current functioning of the occupational injury and disease section of the Social Security system in its mission of providing incentives for prevention. After outlining the organization and specific features of insurance against occupational risks, an initial level of analysis highlights the presence of moral hazard in relations between insurer and company and between company and employee. A second level of analysis and resort to complex agency relationship models, multitask model and third-party model, is necessary to take into account the consequences for occupationa…
The Thunen's rent rediscovered (some reflections on the history of spatial thought)
1989
Von Thünen’s thought about land rent has often been oversimplified by modern economists: the aim of this paper is to analyse the properties of the original rent function of The Isolated State. We give a mathematical reformulation of Thünen’s reasoning and we show its richness, its curiosities and olso its limits. None of the Thünen’s rent functions is linear, and the original model is anable to assure that they are decreasing with distance to the center.

The Dark Side of Value Co-Creation: The Example of French Commercial Architecture
2018
Innovation is a network activity where different actors collaborate. An ethnographic survey of the French commercial architecture industry highlights the ambivalence of this co-production process. The results identify the sources of co-creation and co-destruction related both to the motivations of the actors and their interactions and examines their consequences. Retailers are encouraged to reposition themselves as project leaders, responsible for both assigning roles and mediating between the creative and technical functions. The development of new communication platforms to overcome interpretive biases between the diverse set of actors is also recommended.
