L’équipe de Recherche en Couches Minces Optiques (RCMO) de l’Institut FRESNEL dispose d’un ensemble de machines de dépôt sous vide utilisant le dépôt physique en phase vapeur. La réalisation de fonctions de filtrage complexes nécessite une parfaite maîtrise du processus de dépôt ainsi qu’un contrôle précis et en temps réel de l’épaisseur optique des couches déposées.
In this paper, we investigate on 39 Variable Selection procedures to give an overview of the existing 1 literature for practitioners. "Let the data speak for themselves" has become the motto of many applied researchers 2 since the amount of data has significantly grew. Automatic model selection have been raised by the search 3 for data-driven theories for quite a long time now.
This paper studies the properties of joint-venture relationship between a technologically advanced multinational firm and a local firm operating in a developing economy where the ability to enforce contracts is weak. We formulate a dynamic model of principal-agent relationship in which at any point of time the local firm can quit without legal penalties.
This paper solves a second-best problem where a government has in particular to choose whether to tax ﬁnancial inﬂows (capital controls) or not, and when. A multi-stage optimal control technique is used to this end. First, it is shown that it is optimal to switch in ﬁnite time from capital controls to full ﬁnancial liberalization (zero tax on capital inﬂows) whenever a measure of total wealth is above a certain threshold.
This paper explores the effect of a potential joint-venture breakup on the level of technology transfer in a set-up with exploration-exploitation trade-offs in the presence of time compression costs. We consider a joint-venture relationship between a technologically advanced multinational firm and a local firm operating in a developing economy where the ability to enforce contracts is weak, and the local firm can quit without penalties.
We consider a general control problem with two types of optimal regime switch. The ﬁrst one concerns technological and/or institutional regimes indexed by a ﬁnite number of discrete parameter values, and the second features ecological-like regimes relying on given threshold values for given state variables.
The paper addresses the role of education policies for institutional change. Our paradigmatic model consists of an autocratic elite and a mass of handto- mouth workers. The elite has full political and economic control. First, it anticipates and can avoid revolutionary threats through income redistribution.
