The frontier of indeterminacy in a neo-Keynesian model with staggered prices and wages
We consider a neo-Keynesian model with staggered prices and wages. When both contracts exhibit sluggish adjustment to market conditions, the policy maker faces a trade-off between stabilizing three welfare relevant variables: output, price inflation and wage inflation. We consider a monetary policy rule designed accordingly: the Central Banker can react to both inflations and the output gap. We generalize the Taylor principle in this case: it embeds the frontier of determinacy derived with staggered prices only, it is also symmetric in price and wage inflations. It follows that when staggered labour contracts are considered, wage inflation is also an illegible and efficient target for the Central Banker
A RAINBOW INVERSE PROBLEM
Abstract. We consider the radiative transfer equation (RTE) with reflection in a three-dimensional domain, infinite in two dimensions, and prove an existence result. Then, we study the inverse problem of retrieving the optical parameters from boundary measurements, with help of existing results by Choulli and Stefanov. This theoretical analysis is the framework of an attempt to model the color of the skin. For this purpose, a code has been developed to solve the RTE and to study the sensitivity of the measurements made by biophysicists with respect to the physiological parameters responsible for the optical properties of this complex, multi-layered material
Imaginaire et patrimoine dans la recomposition des territoires du quotidien en Chine. L’exemple des maisons de thé de Chengdu (Sichuan)
Ă€ l’heure oĂą la Chine connaĂ®t de rapides mutations urbaines et sociales, la ville de Chengdu fournit un terrain d’étude privilĂ©ÂgiĂ© pour la comprĂ©hension des nouveaux modes de loisirs et de leur relation aux territoires du quotidien. Les maisons de thĂ© Ă Chengdu, lieux de sociabilitĂ© centraux tout au long du XXe siècle, voient aujourd’hui leur existence menacĂ©e par les reconÂfigurations urbaines, et la modernisation a laissĂ© place Ă de nouvelles formes de lieux de loisirs que certains dĂ©finissent comme des maisons de thĂ© quand d’autres dĂ©jĂ sonnent le glas de leur disparition. De leur confrontation avec le tourisme de masse, la sociĂ©tĂ© de consommation et la concurrence des cafĂ©s, bars et karaokĂ©s, rĂ©sultent de multiples Ă©volutions des formes et des pratiques : installation dans des immeubles, morcelleÂment de l’espace intĂ©rieur, diversification des activitĂ©s. Elles sont la manifestation d’une polarisation sociale croissante, d’une « folklorisation » de la culture populaire et d’une perte d’importance des lieux de quartier et de proximitĂ©, au profit de lieux dĂ©territorialisĂ©s, situĂ©s en ville ou en pĂ©riphĂ©rie.As China goes through rapid urban social changes, the town of Chengdu provides a prime field of study for understanding the latest forms of leisure and the way they are related to everyday life territories. Tea houses in Chengdu, which have been central sociable places throuÂghout the 20th century, now feel threatened by urban reconfigurations, whilst modernization gave way to new leisure places that some define as tea houses when others sound the knell of their disappearance. Because of mass tourism, consumer society and competition with cafes, bars and karaokes, forms and practices have evolved in many ways such as setting up inside buildings, division of inside space, diversificaÂtion of activities. They are the sign of an increasing social polarization, of the folklorisation of popular culture and of a substantial loss of local and easily accessible places to the benefit of deterritorialized places located in towns or on the outskirts
