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

The uneven price impact of energy efficiency ratings on housing segments and implications for public policy and private markets

In the literature, there is extensive, although in some cases inconclusive, evidence on the impact of Energy Performance Certificates (EPC) on housing prices. Nonetheless, the question of whether such an impact is homogenous across residential segments remains highly unexplored. This paper addresses this latter issue utilizing multifamily listing data in metropolitan Barcelona. In doing so, first the entire sample is analyzed using a hedonic model. Second, the sample is split on the basis of a multivariate segmentation. Finally, separated hedonic models are specified again. The results suggest that in general, there is a modest impact of EPC ratings on listing prices, nonetheless it is not homogeneous across housing segments: (1) for the most modern apartments, with state-of-the-art features and active environmental comfort, energy ratings seem to play a null role in the formation of prices; (2) conversely, for the cheapest apartments, apartments boasting the most basic features, and apartments located in low-income areas, the “brown discount” is enormously significant, potentially depreciating the equity of those who have the least resources to carry out an energy retrofit. These results have implications for the assessment of the EPBD and its Spanish transposition, since a very well-intentioned environmental policy could have potentially harmful social repercussions in the absence of corrective measures.Peer ReviewedPostprint (published version

The dynamic effects of shocks to wages and prices in the United States and the euro area

This paper investigates the dynamics of aggregate wages and prices in the United States (US) and the Euro Area (EA) with a special focus on persistence of real wages, wage and price inflation. The analysis is conducted within a structural vector error-correction model, where the structural shocks are identified using the long-run properties of the theoretical model, as well as the cointegrating properties of the estimated system. Overall, in the long run, wage and price inflation emerge as more persistent in the EA than in the US in the face of import price, unemployment, or permanent productivity shocks. This finding is robust to the changes in the sample period and in the models’ specifications entertained in the paper.

The impact of real estate projects and their sustainability characteristics on land values: cause or consequence? two case studies from Santiago, Chile

From the point of view of developers, there is the belief that location determines the main characteristics of real estate projects. On the contrary, the bid rent theory proposes that land receives value from that which it supports, as expressed by means of architectural attributes. In light of two case studies in Santiago, Chile, the relationship between land value and real estate value was studied with the aim of identifying the meaning of this causality and the role of sustainability characteristics – as an expression of emergent architectural attributes – in price formation. It was observed that the interaction between land value and architectural characteristics generates property price through circular causality, where there is a certain typology for each location that can produce submarkets. In this sense, sustainability attributes effectively influence the creation of value – but not linearly – which clearly suggests the presence of housing submarkets according to price level, and a new element in the relationship between land and architectural attributes.Postprint (published version

The great good place : coworking como espaço para aprender design uma framework exploratória

Abstract : In this paper we explore a conceptual framework based on three lines of thinking/work from Patrick Cohendet (Underground/Middleground/Upperground), Ray Oldenburg (The Great Good Place), and Fred Garneti (Heutagogy or Self-determined Learning). To demonstrate the relevance and feasibility of our proposed concept, we review the key factors and definitions of these authors and their work. Although not a theoretical framework, the present paper aims to help us map a part of our research work within the context of the Doctoral Programme in Design at IADE / Universidade Europeia, which triangulates Coworking, Design Learning, and Heutagogy or selfdetermined modes of learning. Ultimately, the aim is to generate new evidence on how such a model of Coworking Design Learning can benefit and betier suit contemporary Design learners.Neste artigo, exploramos uma estrutura conceptual baseada em três linhas de pensamento dos autores Patrick Cohendet (Underground / Middleground / Upperground), Ray Oldenburg (The Great Good Place) e Fred Garneti (Heutagogy or Self-determined Learning). Para demonstrar a relevância e a viabilidade da nossa proposta conceptual, revisitamos os principais fatores e definições destes autores e dos seus trabalhos. Embora não constitua uma framework teórica, o presente trabalho tem como objetivo ajudar a mapear parte do nosso trabalho de pesquisa no contexto do Programa de Doutoramento em Design do IADE / Universidade Europeia, que triangula Coworking, Aprendizagem de Design e Heutagogia ou modos autodeterminados de aprendizagem. Em última instância, o objetivo é tentar produzir novas evidências sobre como um modelo de aprendizagem de Design baseado em espaços de Coworking pode beneficiar e adequar-se melhor aos actuais alunos de Design.info:eu-repo/semantics/publishedVersio

Quantity v/s quality of scientific publications: an analysis for main cities of Spain (2001-2007)

Since the last quarter of the 20th century, most of the world population has experimented an important process of globalization, mainly due to; the accelerated knowledge production, the increase of intangible capital on a macroeconomic scale, the increase in levels of innovation, and the ICT revolution that have democratized access to information and knowledge dissemination. This new economic base, located in cities, is supported on knowledge and information as sources of production and competitiveness. The number of scientific publications on indexed journals is a scale, often used to measure the degree of strength of the scientific sector of a particular place. But this scale ignores the quality of the counted works, i.e. the impact they have generated in the scientific world. This work seeks to highlight the dynamics of scientific production in Spain. Specifically, it aims to analyze the quantity and quality of scientific publications in the period between 2001 and 2007. For this analysis, the quantity is measured by the number of scientific papers published by researchers from a city and the quality by the number of times that works signed by scientists from a city, have been cited by researchers around the world. In this study we establish a bibliometric analysis based on: 1) the number of scientific contributions to municipalities of more than 30,000 people whose information is derived from the SCI-E and 2) the number of citations for the top 10 cities with information derived from Scopus. Finally, we contrast the results of the more representatives cities, with the aim of clarify the relationship between the quantity and quality between quantity and quality of the scientific publication. The results suggest a concentration of quantity and quality of the scientific production in the Spanish metropolitan areas. However, we can provide that ranking who have the main cities in the context of national scientific publication is not similar for both parameters.

Consumer Expenditure and Cointegration

In this paper we estimate the Almost Ideal Demand System (AIDS) for the Portuguese economy. The budget shares and real per capita income are found to be integrated of order one, I(1), but prices seem to be better classified as I(2). This raises new problems, as it is not possible to test for homogeneity and symmetry in a straightforward way. As cointegration is not rejected after the imposition of homogeneity and symmetry restrictions, we conclude that the AIDS is an acceptable characterisation of the Portuguese data on consumer expenditure.
