Effects of competition over quality-adjusted price indexes: an application to the Spanish automobile market

Using a newly constructed data set, we calculate quality-adjusted price indexes after estimating hedonic price regressions from 1988 to 2004 in the Spanish automobile market. The increasing competition was favoured by the removal of trade restrictions and the special plans for the renewal of the Spanish automobile fleet. We find that the increasing degree of competition during those years led to an overall drop in automobile prices by 20 percent which implied considerable consumer gains thanks to higher market efficiency. Additionally, our results indicate that loyalty relevance and discrepancies in automobile reliability declined during those years. This is captured.

Subsistemas input-output y contaminación: una aplicación al sector servicions y las emisiones de CO2 en España

El análisis de subsistemas input-output nos proporciona una herramienta de gran utilidad para estudiar la estructura productiva de los diferentes sectores que componen una economía. En el presente trabajo se ha desarrollado este análisis para estudiar las emisiones de CO2 relacionadas con el conjunto de ramas productivas que conforman el sector servicios. La descomposición de la producción total del subsistema servicios nos permite obtener las emisiones de CO2 relacionadas con diferentes efectos (escala, propio, feed-back y spill over). De los resultados obtenidos, destaca el diferente papel de las distintas ramas productivas de servicios. Las actividades de transporte serían las responsables de las mayores emisiones generadas directamente en el sector. Estas actividades son demandadas por el resto de sectores de la economía en mayor grado que su propia demanda final, teniendo mayor responsabilidad la producción vendida a otros sectores que la propia demanda final. No obstante, para el resto de actividades las emisiones directas e indirectas asociadas a la demanda final son mucho más importantes, por el fuerte efecto de arrastre sobre otras ramas de la economía que ejercen las actividades de servicios. A este respecto, destacan los servicios de Comercio, Hostelería, Inmobiliarias y servicios empresariales y la Administración pública, actividades que reciben escasa atención en el diseño de políticas orientadas a reducir las emisiones, pero que tienen una responsabilidad muy destacable en el fuerte aumento de emisiones experimentado en los últimos años.

Actividad económica, consumo final de energía y requerimientos de energía primaria en Cataluña, 1990-2005. Análisis mediante el uso de los balances energéticos desde una perspectiva input-output

Este trabajo analiza la evolución de los consumos finales de energía en Cataluña durante el periodo 1990-2005. En conjunto, los consumos finales de energía crecen por encima del crecimiento del PIB en términos reales. La disponibilidad actual de datos permite una desagregación en cinco actividades: sector primario; sector industrial; sector servicios; transporte; y sector doméstico. Los aumentos relativos más importantes se dan en los sectores servicios, doméstico y transporte. Es esta última actividad (que incluye el transporte privado y comercial) la que experimenta un mayor aumento en términos absolutos, hasta llegar a representar un consumo final de energía.

Actividad económica y emisiones de CO2 derivadas del consumo de energía en Cataluña, 1990-2005. Análisis mediante el uso de los balances energéticos desde una perspectiva input-output

A lo largo del trabajo hemos analizado, tanto desde una perspectiva agregada, como posteriormente con todo el detalle posible, la evolución experimentada por estas emisiones, teniendo en cuenta las limitaciones de información . Para hacerlo se han utilizado conceptos y precisiones metodológicas ampliamente utilizadas en la literatura científica sobre el tema. Del estudio realizado en la primera parte del trabajo resulta evidente que el importante crecimiento de las emisiones en Cataluña durante el periodo considerado, de un 60.1%, muy superior a la media española (50,5%), se explica como principal factor por el aumento en el PIB per cápita, con un crecimiento del 33,35% . El crecimiento demográfico también habría contribuido de forma importante al incremento en las emisiones totales, con un aumento del 10,5% de la población; sobre todo a partir de 1999, ya que en la década de los noventa la población se mantuvo estable con pocas.

Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MUSIASEM): an outline of rationale and theory

This paper presents an outline of rationale and theory of the MuSIASEM scheme (Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism). First, three points of the rationale behind our MuSIASEM scheme are discussed: (i) endosomatic and exosomatic metabolism in relation to Georgescu-Roegen’s flow-fund scheme; (2) the bioeconomic analogy of hypercycle and dissipative parts in ecosystems; (3) the dramatic reallocation of human time and land use patterns in various sectors of modern economy. Next, a flow-fund representation of the MUSIASEM scheme on three levels (the whole national level, the paid work sectors level, and the agricultural sector level) is illustrated to look at the structure of the human economy in relation to two primary factors: (i) human time - a fund; and (ii) exosomatic energy - a flow. The three levels representation uses extensive and intensive variables simultaneously. Key conceptual tools of the MuSIASEM scheme - mosaic effects and impredicative loop analysis - are explained using the three level flow-fund representation. Finally, we claim that the MuSIASEM scheme can be seen as a multi-purpose grammar useful to deal with sustainability issues.

An application of MSIASM to Chinese exosomatic energy metabolism

The methodology of Multi-Scale Integrated The methodology of Multi-Scale Integrated Analysis of Societal Metabolism (MSIASM) is applied to analyze the Chinese economy. This paper presents four tasks: (i) identifying a set of benchmarks that makes it possible to compare various characteristics of the Chinese economy with those of other country groups and the world (level) average; (ii) explaining the differences over the selected set of benchmarks, by looking at the characteristics of the various sub-sectors of the Chinese economy; (iii) understanding existing trends and future feasible future development paths for China by studying the existence of reciprocal constraints between the whole economy and its sub-sectors; and (iv) examining plausible future scenarios of development.

Different trajectories of exosomatic energy metabolism for Brazil, Chile and Venezuela: using the MSIASM approach

Economic development goes hand in hand with an increase in the consumption of natural resources. Some analysts use material flows to describe such relationship [Eurostat 2001, Weisz et al., 2006], or exergy [Ayres et al., 2003]. Instead this paper will use a characterisation of the exosomatic energy metabolism based on expected benchmark values to describe possible constraints to economic development posed by available human time and energy. The aim of the paper is to identify types of exosomatic energy metabolism of different societies to interpret its consequences for economic development. This is done with the application of the accounting methodology called Multi-Scale Integrated Analysis of Societal Metabolism (MSIASM) to the particular case of energy metabolism for the analysis of the economies of Brazil, Chile and Venezuela.

Los Distritos industriales en la Europa mediterránea: los mapas de Italia y España

El presente trabajo ofrece una comparación de los mapas de distritos industriales marshallianos de España e Italia elaborados a partir de la metodología Sforzi - ISTAT (2006). Como principales similitudes se destaca que los distritos industriales son una realidad generalizada en ambos países y su importancia relativa es equivalente. se especializan principalmente en industria ligera y mecánica. y muestran una elevada concentración territorial. Como principales diferencias se destaca la mayor especialización relativa de los distritos industriales de España en productos para la casa e industria alimentaria. mientras que en Italia es superior la especialización relativa en industria mecánica. y en textil y confección; la menor dimensión de los distritos industriales españoles respecto de los italianos; y que los distritos industriales españoles tienen una dinámica positiva y superior a la del resto del país. mientras en Italia su dinámica negativa contrasta con la del resto de la economía.

Do creative industries cluster? mapping creative local production systems in Italy

An important debate on the role of creativity and culture as factors of local economic development is distinctly emerging. Despite the emphasis put on the theoretical definition of these concepts, it is necessary to strengthen comparative research for the identification and analysis of the kind of creativity embedded in the territory as well as its determinants. Creative local production systems are identified in Italy and Spain departing from local labour markets as territorial units, and focusing on two different kinds of creative

Why Catalonia will see its energy metabolism increase in the near future: an application of MuSIASEM

This paper applies the so-called Multi-Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) to the economy of the Spanish region of Catalonia. By applying Georgescu-Roegen's fund-flow model, it arrives at the conclusion that within a context of the end of cheap oil, the current development model based on the growth of low productivity sectors such as services and construction must change. The change is needed not only because of the increasing scarcity of affordable energy carriers, or because of the increasing environmental impact that the present development represents, but also because of an ageing population that demands labour productivity gains. This will imply industry requiring more energy consumption per worker in order to increase its productivity, and therefore its competitiveness. Thus, we conclude that energy intensity, and exosomatic energy metabolism of Catalonia will increase dramatically in the near future unless major conservation efforts are implemented in both the household and transport sectors.

Industrial districts, innovation and I-district

The I-district effect hypothesis establishes the existence of highly intense innovation in Marshallian industrial districts due to the presence of external localization economies. However, industrial districts are characterized by specific manufacturing specializations in such a way that this effect could be due to these dominant specializations. The objective of this research is to test whether the effect is explained by the conditions of the territory or by the industrial specialization and to provide additional evidence of the existence and causes of the highly intense innovation in industrial districts (I-district effect). The estimates for Spain of a fixed effects model interacting territory and industry suggest that the high innovative performance of industrial districts is maintained across sectors whereas the industrial specialization behaves differently depending on the type of local production system in which it is placed. The I-district effect is related to the conditions of the territory more than to the industrial specialization. The territory is a key variable in explaining the processes of innovation and should be considered a basic dimension in the design of innovation and industrial policies.

Labor supply response to international migration and remittances in the Republic of Haiti

The Republic of Haiti is the prime international remittances recipient country in the Latin American and Caribbean (LAC) region relative to its gross domestic product (GDP). The downside of this observation may be that this country is also the first exporter of skilled workers in the world by population size. The present research uses a zero-altered negative binomial (with logit inflation) to model households' international migration decision process, and endogenous regressors' Amemiya Generalized Least Squares method (instrumental variable Tobit, IV-Tobit) to account for selectivity and endogeneity issues in assessing the impact of remittances on labor market outcomes. Results are in line with what has been found so far in this literature in terms of a decline of labor supply in the presence of remittances. However, the impact of international remittances does not seem to be important in determining recipient households' labor participation behavior, particularly for women.

Tourism and urban transport: holding demand pressure under supply constraints

Scholars and local planners are increasingly interested in tourism contribution to economic and social development. To this regard, several European cities lead the world rankings on tourist arrivals, and their governments have promoted tourism activity. Mobility is an essential service for tourists visiting large cities, since it is a crucial factor for their comfort. In addition, it facilitates the spread of benefits across the city. The aim of this study is to determine whether city planners respond to this additional urban transport demand pressure by extending supply services. We use an international database of European cities. Our results confirm that tourism intensity is a demand enhancing factor on urban transport. Contrarily, cities do not seem to address this pressure by increasing service supply. This suggests that tourism exerts a positive externality on public transport since it provides additional funding for these services, but it imposes as well external costs on resident users because of congestion given supply constraints.

Scheduled service versus personal transportation: the role of distance

This paper analyzes both theoretically and empirically the relationship between distance and frequency of scheduled transportation services. We study the interaction between a monopoly firm providing high-speed scheduled service and personal trans- portation (i.e., car). Most interestingly, the carrier chooses to increase frequency of service on longer routes when competing with personal transportation because provid- ing a higher frequency (at extra cost) it can also charge higher fares that can boost its profits. However, when driving is not a relevant option, frequency of service de- creases for longer flights consistently with prior studies. An empirical application of our analysis to the European airline industry con?rms the predictions of our theoretical model.

Assessing the assignation of public subsidies: Do the experts choose the most efficient R&D projects?

The implementation of public programs to support business R&D projects requires the establishment of a selection process. This selection process faces various difficulties, which include the measurement of the impact of the R&D projects as well as selection process optimization among projects with multiple, and sometimes incomparable, performance indicators. To this end, public agencies generally use the peer review method, which, while presenting some advantages, also demonstrates significant drawbacks. Private firms, on the other hand, tend toward more quantitative methods, such as Data Envelopment Analysis (DEA), in their pursuit of R&D investment optimization. In this paper, the performance of a public agency peer review method of project selection is compared with an alternative DEA method.
