A quoi bon former des médecins généralistes ? Un modèle d’apprentissage et un modèle professionnel sous tensions
2014
Cet article retrace les transformations intervenues dans la formation des medecins generalistes en France et interroge leurs effets en termes de construction d’une specialite medicale « medecine generale » comme de renouvellement de l’offre de soins. Il prend principalement appui sur une enquete ethnographique au long cours dans le milieu des enseignants de medecine generale et sur le suivi d’une cohorte d’anciens internes de la filiere. La premiere partie privilegie le point de vue de la construction de l’offre de formation specifique a la medecine generale, qui a justement fait de la pedagogie son fer de lance. La deuxieme partie interroge la reception qu’en ont les jeunes medecins, dans …

Explanations of success and failure in management learning : What can we learn from Nokia's rise and fall
2016
International audience; In this paper, we study the changing explanations of success and failure over the course of a firm's history. We build on a discursive approach that highlights the role of narrative attributions in making sense of corporate performance. Specifically, we analyze how the Nokia Corporation was framed first as a success and later as a failure and how these dimensions of performance were explained in various actors' narrative accounts. In both the success and failure accounts, our analysis revealed a striking black-and-white picture that resulted in the institutionalization of Nokia's metanarratives of success and failure. Our findings also reveal a number of discursive a…
Modeling foreign exchange market activity around macroeconomic news: Hawkes-process approach
2015
We present a Hawkes-model approach to the foreign exchange market in which the high-frequency price dynamics is affected by a self-exciting mechanism and an exogenous component, generated by the pre-announced arrival of macroeconomic news. By focusing on time windows around the news announcement, we find that the model is able to capture the increase of trading activity after the news, both when the news has a sizable effect on volatility and when this effect is negligible, either because the news in not important or because the announcement is in line with the forecast by analysts. We extend the model by considering noncausal effects, due to the fact that the existence of the news (but not…

Operating leverage and the cost of debt in European agri-food firms
2020
Aim of study: To analyse the effect that operating leverage exerts on the cost of debt of agri-food firms in Europe, both in isolation and indirectly through its other risk factors.Area of study: We used panel data made up of 18,360 European firms from 2009 to 2016 (146,880 observations).Material and methods: The data were extracted from the ORBIS database and EUROSTAT. The econometric approach was estimated by the Generalized Method of Moments.Main results: The results obtained confirm that operating leverage or cost structure, in addition to affecting the cost of debt, also affects the relationship between that cost and other sources of risk. More specifically, indebtedness, size, specifi…
