We analyze the welfare properties of the competitive equilibrium in a capital accumulation model where individual preferences are subjected to both habit formation and consumption spillovers. We also discuss how consumption externalities and habits interact to generate an inefficient dynamic equilibrium. Finally, we characterize optimal tax policies aimed to restore efficient decentralized paths.

We analyze the dynamic behavior and the welfare properties of the equilibrium path of a growth model where both habits and consumption externalities affect the utility of consumers. We discuss the effects of flat rate income taxes and characterize the optimal income taxation policy. We show that, when consumption externalities and habit adjusted consumption are not perfect substitutes, a counter-cyclical income tax rate allows the competitive equilibrium to replicate the efficient path. Our analysis highlights the crucial role played by complementarities between externalities and habits in order to generate an inefficient dynamic equilibrium.

The objective of this paper is to estimate a petrol consumption function for Spain and to evaluate the redistributive effects of petrol taxation. We use micro data from the Spanish Household Budget Survey of 1990/91 and model petrol consumption taking into account the effect that income changes may have on car ownership levels, as well as the differences that exist between expenditure and consumption. Our results show the importance that household structure, place of residence and income have on petrol consumption. We are able to compute income elasticities of petrol expenditure, both conditional and unconditional on the level of car ownership. Non-conditional elasticities, while always very close to unit values, are lower for higher income households and for those living in rural areas or small cities. When car ownership levels are taken into account, conditional elasticities are obtained that are around one half the value of the non- conditional ones, being fairly stable across income categories and city sizes. As regards the redistributive effects of petrol taxation, we observe that for the lowest income deciles the share of petrol expenditure increases with income, and thus the tax can be regarded as progressive. However, after a certain income level the tax proves to be regressive.

In this paper we analyze the determination of "key" sectors in the final energy consumption. We approach this issue from an input-output perspective and we design a methodology based on the elasticities of the demands of final energy consumption. As an exercise, we apply the proposed methodology to the Spanish economy. The analysis allows us to indicate the greater or lesser relevance of the different sectors in the consumption of final energy, pointing out which sectors deserve greater attention in the Spanish case and showing the implications for energy policy.

Enfront les metodologies tradicionals centrades en la figura del professor i la utilització de manuals d’aprenentatge de caràcter conductista, la utilització de metodologies cooperatives per a l’ensenyament i l’aprenentatge musical incrementa significativament el debat a l’aula i proporciona una perspectiva heurística del fet creatiu, que afavoreix la construcció del coneixement musical.

Treball de recerca realitzat per un alumne d’ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l’any 2008. El nombre d’or és un recurs matemàtic que utilitza el compositor per dissenyar una estructura que li permeti organitzar el material del discurs musical que ha estat dictat per la seva inspiració, de forma que, tot i mantenir-se fidel als punts que defineixen l’estructura fonamentada en el nombre d’or, la seva llibertat creativa no es veu limitada. El fet de sotmetre el discurs musical espontani a uns paràmetres matemàtics concrets dóna a l’obra coherència i ordre. Aquest és precisament l’efecte cercat per tots els compositors que han utilitzat el nombre d’or en les seves composicions. S’ha procedit a la recerca de bibliografia específica en la matèria. Posteriorment, s’ha desenvolupat l’anàlisi de diverses obres estructurades d’acord amb els cànons auris seguint les pautes d’anàlisi obtingudes a partir de la bibliografia. Finalment, s’ha compost una obra musical estructurada segons les directrius àuries a partir dels elements explicitats per l’anàlisi.

The sequence of pitches which form a musical melody can be transposed or inverted. Since the 1970s, music theorists have modeled musical transposition and inversion in terms of an action of the dihedral group of order 24. More recently music theorists have found an intriguing second way that the dihedral group of order 24 acts on the set of major and minor triads. We illustrate both geometrically and algebraically how these two actions are dual. Both actions and their duality have been used to analyze works of music as diverse as Hindemith and the Beatles.

Treball de recerca realitzat per un alumne d'ensenyament secundari i guardonat amb un Premi CIRIT per fomentar l'esperit científic del Jovent l'any 2009. L’objectiu d’aquest treball de recerca és la creació d’un dispositiu encarregat de centralitzar totes les necessitats multimèdia de casa nostra i distribuir aquest contingut a tots els terminals de la xarxa local d’una manera senzilla i automatitzada. Aquest dispositiu s’ha dissenyat per estar connectat a una televisió d’alta definició, que permetrà la reproducció i l’organització de tot el nostre multimèdia d’una manera còmoda i fàcil. El media center s’encarrega de gestionar la nostra filmoteca, fototeca, biblioteca musical i sèries de TV de manera transparent i automàtica. A més a més, l’usuari pot accedir a tot el multimèdia emmagatzemat al media center des de qualsevol dispositiu de la xarxa local a través de protocols com CIFS o UPnP, en un intent de replicar el cloud computing a escala local. El dispositiu ha estat dissenyat per a suportar tot tipus de formats i subtítols, assegurant la compatibilitat total amb arxius lliures de DRM. El seu disseny minimalista i silenciós el fa perfecte per a substituir el reproductor de DVD de la sala. Tot això sense oblidar el seu baix consum, de l’ordre d’un 75% inferior al d’un PC convencional.

The main goal of this research is explain the impact of the new trends of wine consumption, and the way these enterprises adapted to the circumstances. The hypothesis is that the Spanish companies had to start a deep and traumatic restructuring process, with the aim of surviving adequately in the changeable wine national and international markets. Heavy technological investments were made, with serious finance problems, during the eighties and nineties. We will see this from two specific cases, the Cooperatives "San Isidro" and "Rosario", located in the Region of Murcia, in the Spanish southeast.

This paper analyzes the role of the energy transformation index and of final energy consumption per GDP unit in the disparities in energy intensity across countries. In that vein, we use a Theil decomposition approach to analyze global primary energy intensity inequality as well as inequality across different regions of the world and inequality within these regions. The paper first demonstrates the pre-eminence of divergence in final energy consumption per GDP unit in explaining global primary energy intensity inequality and its evolution during the 1971-2006 period. Secondly, it shows the lower (albeit non negligible) impact of the transformation index in global primary energy inequality. Thirdly, the relevance of regions as unit of analysis in studying crosscountry energy intensity inequality and their explanatory factors is highlighted. And finally, how regions around the world differ as to the relevance of the energy transformation index in explaining primary energy intensity inequality.

Growth of 'global cities' in the 1980s was supposed to have involved an occupational polarisation, including growth of low paid service jobs. Though held to be untrue for European cities, at the time, some such growth did emerge in London a decade later than first reported for New York. The question is whether there was simply a delay before London conformed to the global city model, or whether another distinct cause was at work in both cases. This paper proposes that the critical factor in both cases was actually an upsurge of immigration from poor countries providing an elastic supply of cheap labour. This hypothesis and its counterpart based on growth in elite jobs are tested econometrically for the British case with regional data spanning 1975-2008, finding some support for both effects, but with immigration from poor countries as the crucial influence in late 1990s London.
