Introduzione critica all'edizione Italiana del libro : HQE, R.Ricciotti, traduzione A. delli Ponti, Alinea Editore, 2008
No full textL'introduzione presenta ai lettori italiani il testo critico di Rudy Ricciotti (Grand Prix National de l'Architecture 2006-France). In particolare chiarendo il contesto di riferimento del testo e il quadro operativo cui l'architetto fa riferimento, specificando le leggi e le direttive UE oggetto dell'analisi di Ricciotti, permettendo cosi al lettore italiano di comprendere i moniti e i suggerimenti contenuti nell'opera. Il testo di Ricciotti, redatto tra il 2005 e il 2006, tratta infatti dell'applicazione in ambito francese di direttive ambientali Europee, che dovevano ancora trovare un riscontro nella legislazione italiana. All'introduzione, il curatore-traduttore associa un corpus di note esplicative in conclusione di volume

Implementation, Elimination of Weakly Dominated Strategies and Evolutionary Dynamics
No full textThis paper studies convergence and stability properties of Sjostrom's (1994) mechanism, under the assumption that boundedly rational players find their way to equilibrium using monotonic evolutionary dynamics and best-reply dynamics. This mechanism implements most social choice functions in economic environments using as a solution concept one round of deletion of weakly dominated strategies and one round of deletion of strictly dominated strategies. However, there are other sets of Nash equilibrium, whose payoffs may be very different from those desired by the social choice function. With monotonic dynamics, all these sets of equilibrium contain limit points of the evolutionary dynamics. Furthermore, even if the dynamics converge to the "right" set of equilibria (i.e., the one which contains the solution of the mechanism), it may converge to an equilibrium which is worse in welfare terms. In contrast with this result, any interior solution of the best-reply dynamics converges to the equilibrium whose outcome the planner desires. (Copyright: Elsevier)
GRAND PARIS III. The infrastructures of modern Paris put to the test by the Grand Paris
No full textThe Material and Immaterial infrastructures of modern Paris are currently put to the test by the Grand Paris initiative. It is difficult to reduce the complexities of the metropolis into commensurable units, symbolically unitary, spatially defined and therefore capable of helping us to find a clear
ideogrammatic synthesis, of the urban post-post-modern condition. If we were to adventure into this exercise on the territory of the Parisian metropolis a broad range of places and urban protagonists would rapidly emerge, leaving us the embarrassment (and the pleasure) of the choice.
Therefore, how can we select the points, the lines and the routes that identify and distinguish what Paris and the Grand Paris are from what they are not?
How can we define a list of the priorities and the correct dialectic relationship between reading scales and project? Beyond any possible evaluation of the seemingly neo-liberal economic-political
project which is at the origin of the initiative, we can say that the paradoxical mission that emerges from the Grand Paris’ imagination exercise is that of developing a new vision, a general theory of the metropolis, which reunifies in a retroactive unicum, the planning multiplicities in a constantly updated state on its territory, in search of a more reactive and elastic meta and macro-planning
instrument than that offered by regional urban studies with the SDRIF (Regional Directional Scheme of Ile-de-France), by many accused of being excessively “slow” compared to the dynamics of territorial development. The search for a strategic infrastructure, that keeps together the idea of a global metropolis with that of a local geography, not through the means of a mechanic neo cartesian approach, by rigidly combining scales and projects in distinctly separated units of time and space, but rather through a dialectic articulation, complex and retroactive, between different scales and different temporalities of the metropolis. How can the local integrate itself with the global in the metropolitan project? What type of gouvernance can guarantee a sustainable balance between the ambitions of two very different scales and between protagonists of metropolitan life with, at times, antagonistic requirements? Which specific metropolitan landscapes can help us in this synthesis exercise? It is probably necessary to analyse the recent transformations in the
immaterial infrastructure of the Grand Paris’ gouvernance and, at the same, observe how the material and symbolic infrastructure of the French capital can evolve in its distinctive characteristics.
In this third dossier we walk about a transversal path, moving from an initial glance at the current condition of the emerging gouvernance system, referred to as the Immaterial-Soft Structure of
this metropolis-in the making, to the design analysis of two urban metropolitan objects; two hard infrastructures charged with such a significative symbolic and strategic status that they have attracted some brilliant theoretical reflection with significative design outcome, The Boulevard Périphérique and La Défense. Two protagonists of the contemporary design literature of Paris and I-d-F. We’ve discussed of the previous topic with Prof. Bertrand Lemoine, General Director of the AIGP-Ateliers du Grand Paris, an institution midway placed between the political-territorial instituions of GP and the world of Urban Design professionals, AIGP is currently launching a wide
international consultation open to groups of Urbandesign firms on the topic of Greater Paris, Habitat and Metropolitan Systems. We’ve then met Pierre Alain Trévelo, founder, with Antoine Viger-Kohler, of TVK Architectes-Urbanistes, expert of the Boulevard Périphérique and of the Parisian metropolitan condition, as well as author of two essential books for the understanding
of the present condition of the Périphérique: No-Limit and La Ville du Périphérique.
The topic of La Défense, was deepened with the contribution of Clement Blanchet, Associated Architect at OMA and director of OMA’s French projects, author, with Rem Koolhaas of Memorandum La Défense, a comprehensive text on OMA’s projects for La Défense
Conventions and Social Mobility in Bargaining Situations
No full textThis paper studies the evolution of a population whose members use their social class to coordinate their actions in a simple tacit bargaining game. In the spirit of Rosenthal and Landau (1979), we interpret the equilibrium behaviours that the players may adopt, as a function of their class, as customs. Players may change their class depending on the outcome of the game, and may also change their custom, as a result of some learning process. We are interested in the characterization of the fixed points of the adjustment process over the space of classes and customs from a distributional point of view. We find that, although any custom (when it operates alone) generates the same limiting class distribution as any other, these limiting distributions can be ranked with respect of their mobility. If players are allowed to change their custom when they find it unsatisfactory, then social mobility appears to be the key variable to predict the type of custom which will predominate in the long run even though, in general, no one custom is dominant. In particular, customs which promote social mobility appear to exhibit, in all the cases we have analysed, stronger stability properties
Evolutionary Stability of Inequality Structures
No full textThis paper studies the evolution of a population whose members
compare their relative income to coordinate actions in a simple bargaining game. Two alternative customs are considered: one in which difference in income (i.e. difference in social class) is large enough to justify difference in behavior, and another in which difference in income is perceived as not sufficient to justify a difference in behavior. Although we constrain agents to these bargaining strategies, reference class boundaries are subjectively determined.
Our model yields the following conclusions. If individuals form fixed,
unambiguous images of their position in the social structure, then social inequality will eventually disappear, as the income of each individual converges to a uniform level.
On the other hand, if social images vary from individual to individual (and
evolve through some learning process), then social inequality may persist, with class consciousness (i.e. narrower subjective class boundaries) being most pronounced in those who occupy the extreme positions (either very rich or very poor) of the social ranking
