Propriété privée | EPFL Graph Search

La propriété privée correspond au droit d’user, de jouir et de disposer d’une chose de manière propre, exclusive et absolue sous les restrictions établies par la loi. Il s'agit de la propriété qui appartient en propre à un individu, ou à plusieurs personnes privées, ou encore, depuis le , à une entreprise ou une autre personne morale. Histoire Il est probable que la propriété privée n'apparaît pas au début de la préhistoire. Elle est certainement absente du paléolithique, période des chasseurs-cueilleurs. C'est le fameux thème ou mythe du « communisme primitif ». Au mésolithique, la règle du partage communautaire persiste. La propriété privée a dû apparaître au néolithique (agriculteurs-pasteurs, domestication des animaux, culture de la terre, sédentarisation), peut-être avec les premiers villages. Douglas North (Structure and Change in Economic History, 1981) place la première révolution industrielle au néolithique, 14.000 ans av. J.-C., sur les rives de l’Euphrate et du

The Advent of the Sharing Culture and its Effect on Product Pricing

Maryam Razeghian Jahromi, Thomas Alois Weber

Empirical observations suggest that consumers' propensity towards sharing varies with culture and the individuals' socio-demographic characteristics. In an economy with overlapping generations of heterogeneous consumers, we study optimal dynamic selling by a durable-goods monopolist in equilibrium. Feasible dynamic pricing strategies include second-degree price discrimination offering intertemporal consumption bundles in the form of rental and/or purchase options. We find that as the population's peer-trade propensity increases, possibly due to a cultural shift from private ownership to collective consumption, the durable-goods monopolist's optimal strategy shifts from unbundling (offering exclusively rentals), via mixed bundling (offering the options of rental and purchase side-by-side), to pure bundling (offering purchase only). We show that an increase in peer-trade propensity has an ambiguous effect on the firm's profit. Cultural shifts from low to high peer-trade propensity may be delayed by a firm's attempts to artificially disable sharing markets by offering overly low rental rates. However, beyond a certain threshold of peer-trade propensity, the firm prefers a cultural transition to an access-based economy. The underlying reason is that the asset base of a sharing economy ultimately depends on the firm's output, so that a portion of the anticipated rents from sharing can be captured by the durable-goods monopolist.

Re-imagining the collective space

Valentin Daniel Maurice Bourdon

Reproduction can be perceived in two opposite ways from the urban planning point of view, both as a driving force and as a braking weight. Driving force because urban phenomena are precisely produced by re-producing, and especially by reproducing the fundamental relation between public space and private volumes. Strength and longevity of traditional cities usually come from continuities, and peculiarly from this elementary one. The renunciation of this substantial quality is undoubtedly one of the main criticisms addressed to the modern movement. Rediscovered at the end of the 20th century, it could again be underestimated at the dawn of this new century, characterized by reinvention, rupture and search for alternatives. Nowadays, reproduction is widely associated to a deep negative connotation: as an obstacle to personal overtaking, or a resistance to collective innovation. But according to sustainability perspectives, there are probably still lessons to be learned from the urban capacity to cross time with the same intensity. Even to support alternatives, part of continuity can be useful, by imputing historical thickness in vulnerable innovations. While keeping a critical attention, it may be appropriate, even today, to consider reproduction as an urban potentiality. As Bernardo Secchi noted in La ville des riches et la ville des pauvres, urban planning - but also architecture in the largest sense - should take advantage of the capacity of space to oppose the resistance of its own inertia to social change (SECCHI, 2013). He also attributes to space the capacity of proposing an oriented trajectory, linked to this pre-existing form. In this context, the ambiguous trajectory given by the powerful relationship between public and private space deserves to be attentively studied. A careful reading of the evolution of this central dualism reveals the relatively silent presence of a third entity: the collective space. In comparison with the importance of a third way in economic and political fields (OSTROM, 1990), architecture seems to suffer from a significant gap. This transdisciplinary approach brings to light, in the architectural domain, the theoretical discontinuity that has long been given to intermediate space, between public space and private property. The architectural challenge around its own third way has long been reduced to the gradual register, without asserting itself as a status, necessary and complementary to the other two components of urbanity. As a very ancient urban element, and relatively recurrent in the formation of cities, collective space presents both all the transcendent abilities of reproduction, but also a precious flexibility mainly linked to its absence of theoretical formulation. Let's give a new emancipated orientation to this underestimated component, overshadowed by a rooted binary reading of the city.
