Identifying residential sub-markets using intra-urban migrations: the case of study of Barcelona’s neighborhoods

The dynamic evolution of the real estate market, as well as the sophistications of the interactions of the actors involved in it have caused that, contrary to classical economic theory, the real estate market is increasingly being thought of as a set of submarkets. This is because, among other things, the modeling of a segmented housing market allows, on the one hand, to design housing policies that are better adapted to the needs of the population, but on the other hand, it allows the generation of both marketing and supply strategies Oriented to specific population sectors. Such strategies in theory should behave as options with relatively low uncertainty, thus representing an attractive offer to all market players. However, in praxis, the segmentation of the real estate market is usually modeled on the offer. It is therefore that this paper proposes a modeling from observed preferences3 seen through intraurban migrations. In particular, it is proposed to model the market through the interaction value of Coombes, scaling the results in order to visualize the resulting submarket structure from the construction of a PAM (Partitioning Algorithm Medoids).Peer ReviewedPostprint (published version

Spatially Integrated Social Research and Official Statistics: Methodological Remarks and Empirical Results on Local Development

This paper aims to elucidate some aspects of confluence of thedevelopments in modern methods of spatial analysis and in the public statistics’data generating processes, along with empirical illustration of theseinterconnections from the development policy evaluation standpoint. Especially,how the growing availability of data at the finest level of territorial division(such as commune/gmina-level data within the Local Data Bank system) mayimprove decisional processes at the regional and local level, while payingspecial attention to allocation of resources assuming geographic system oftargeting public support or intervention. Three interrelated questions that areempirically treated in the context of both β-convergence and σ-convergence issues at the local level involve (i) measurement of the level of local(under)development /local deprivation; (ii) assessment of how responsive andequitable are distributive policies in the domain of area-addressed publicresources; and (iii) evaluation of their impacts in terms of convergence andsocial cohesion, which are among chief objectives of development policy(especially in the ‘new’ EU member states).Celem artykułu jest podkreślenie współzależności pomiędzy rozwojem nowoczesnych metod analizy przestrzennej a podażą odpowiednich danych generowanych w ramach statystyki publicznej. Przedmiotem rozważań jest sposób w jaki rosnąca dostępność danych na poziomie jednostek terytorialnych (gmin), może zwiększyć efektywność procesów decyzyjnych zachodzących na szczeblu lokalnym i regionalnym, ze szczególnym uwzględnieniem decyzji dotyczących alokacji publicznych środków rozwoju (lokalnego) poprzez tzw. geograficzne adresowanie interwencji publicznych
