SCREENING IN SPACE: RICH AND POOR CONSUMERS IN A LINEAR CITY

Unlike standard models of monopolistic screening (second-degree price discrimination), we consider a situation where consumers are heterogeneous not only vertically, in their willingness to pay, but also horizontally, in their tastes or "addresses'' a la Hotelling's Linear City. For such a screening game, a novel model is composed. We formulate the game as an optimization program, prove the existence of equilibria, develop a method to calculate equilibria, and characterize their properties. Namely, the solution structure of the resulting menu of contracts can be either a "chain of envy'' like in usual screening or a number of disconnected chains. Unlike usual screening, "almost all'' consumers get positive informational rent. Importantly, the model can be extended to oligopoly screening.

Infrascape urbanism: beyond the landscape of linear city

Across a breadth of disciplines, the criticism of automobile dependence and the re-conceptualization of mass transit infrastructure have become critical matters of concern. This thesis recognizes these concerns as architectural issues, and argues that design methodology can integrate solutions which respond to the challenges of our decentralized and fragmented urban landscape. The following thesis is an investigation of the relationship between infrastructure and architecture, which explores and identifies opportunities within the unique challenges posed by transportation within the context of the rapid densification of the Greater Golden Horseshoe Area. Rather than subscribing to the utilitarian foundation of infrastructure, this thesis recognizes the significant design potential within this operative system and morphology. In doing so, the thesis project proposes a disciplinary hybrid, which calibrates and synthesizes landscape, infrastructure and architecture.

The Territory of the Grand Tetouan as Linear City: Between Description and Project

This article, based upon pedagogical experimentation in development in a master-level architecture studio at the ULB School of Architecture (Brussels), focuses on the concept of a linear city in a metropolitan context. This concept is proposed by the Grand Tetouan (North Morocco) spatial development scheme as a framework to think about the future of this territory. The interest of the concept lies in its being both a descriptive and project-oriented tool, which allows working with students on the intricate relationship between these two moments of urban design. The coastal region has been the subject of a proposal for a “linear garden city” by a follower of Soria y Mata, Hilarión González del Castillo (1929), a project that left traces on the “palimpsest” (Corboz, 1983/2001) of the actual territory. The idea of the linear city, which has been, throughout the 20th century, a recurrent thematic in urban planning theory and practice dealing with the issue of industrial development of the modern city can be, in the specific case of the Grand Tetouan region, re-examined through the lens of tourism as an industry. The exploration is based on an analytical approach by the use of the notion of urban material (Boeri, Lanzani, & Marini, 1993; Viganò, 1999), an approach that creates the conditions of understanding (describing/designing) the existing territory through the mapping of its physical elements, a description that can then be used to develop an analysis of the forms of production of these elements and the complexity of their uses: how the city is, formally and socially, built (Secchi, 1989).
