This paper presents a comparative statics result on a rental housing market. The relationship between the qualities of apartments and their rents is investigated. Our comparative statics considers rent changes when an improvement occurs in a local area of the market. We show that rents go up locally in response to the improvement, but rents go down in the inner area of the city. To show the dis...

The aim of these lecture notes is a description of the statics and dynamics of zero-range processes and related models. After revisiting some conceptual aspects of the subject, emphasis is then put on the study of the class of zero-range processes for which a condensation transition arises. From urn models to zero-range processes: statics and dynamics 2 Introduction
