Human Capital Composition and Economic Growth at a Regional Level

With this paper we build a two-region model where both innovation and imitation are performed. In particular imitation takes the form of technological spillovers that lagging regions may exploit given certain human capital conditions. We show how the high skill content of each region’s workforce (rather than the average human capital stock) is crucial to determine convergence towards the income level of the leader region and to exploit the technological spillovers coming from the frontier. The same applies to bureaucratic/institutional quality which are conductive to higher growth in the long run. We test successfully our theoretical result over Spanish regions for the period between 1960 and 1997. We exploit system GMM estimators which allow us to correctly deal with endogeneity problems and small sample bias.

Estudi de l'evolució dels nivells d'immissió dels contaminant emesos per la incineradora de Campdorà (Girona)

L’ objectiu principal d’ aquest treball és l’ anàlisi de l’ evolució de l’ impacte ambiental produït per l’ emissió de gasos contaminants procedents de la incineradora de Campdorà (Girona). Els gasos contaminants objecte d’ estudi són: partícules de suspensió totals, clorur d’ hidrogen, diòxid de nitrogen, monòxid de carboni i diòxid de sofre. S’ ha realitzat la simulació de la dispersió atmosfèrica dels contaminants emesos per la incineradora de Campdorà mitjançant el programa informàtic ISC-AERMOD View. Com a resultat, s’ obtenen una sèrie de mapes de concentració on es mostren els diferents nivells d’ immissió detectats en la zona objecte d’ estudi. Els resultats mostren com la incorporació de noves tecnologies i tractaments de gasos en la incineradora de Campdorà han representat una reducció dels nivells d’ immissió de la zona, millorant la qualitat de l’ aire i disminuint l’ impacte ambiental que produeixen les emissions contaminants

Presidents and parties in regional politics: Italy and Spain compared

This article examines the relationship between political parties and regional presidents in Italy and Spain, adopting a comparative case study approach based on extensive archival analysis and in-depth interviews with regional politicians. The findings confirm a strong pattern of growing presidentialism at regional level, regardless of whether there are formal mechanisms for direct election, and regardless of the partisan composition of regional government. Regional presidents tend to exert their growing power through a personalised control of regional party organisations, rather than governing past parties in a direct appeal to the electorate. Nevertheless, parties can still present a significant constraint on regional presidents, so successful regional presidents tend to maintain a mediating form of leadership and fully exploit the opportunities for party patronage to build up their support and smooth governing tensions. An autonomist drive helps presidents hold together disparate coalitions or loose parties at regional level, but their lack of internal coherence presents major problems when it comes to political succession.

Human capital and regional development

We investigate the determinants of regional development using a newly constructed database of 1569 sub-national regions from 110 countries covering 74 percent of the world s surface and 97 percent of its GDP. We combine the cross-regional analysis of geographic, institutional, cultural, and human capital determinants of regional development with an examination of productivity in several thousand establishments located in these regions. To organize the discussion, we present a new model of regional development that introduces into a standard migration framework elements of both the Lucas (1978) model of the allocation of talent between entrepreneurship and work, and the Lucas (1988) model of human capital externalities. The evidence points to the paramount importance of human capital in accounting for regional differences in development, but also suggests from model estimation and calibration that entrepreneurial inputs and possibly human capital externalities help understand the data.

Regional industrialisation without national growth: The Catalan industrialization and the growth of Spanish economy (1830-1861)

This paper has two main objectives. First, it provides a stylised descriptionof the Catalan industrial path of the period 1830-1861. Second, it reviewsthe evolution of the Catalan industry in the Spanish context and, thus, canserve to describe the relative importance of the Catalan industrialexperience. Consequently, it is mainly devoted to computing and analysing thegrowth rates of Catalan industries during the early phase of industrialisation.The results show that Catalonia experienced a true process ofindustrialisation during the period 1830 to 1861, but that its contributionin rapid increase in Spanish GDP was relatively small.

L'esquerda ecològica: residus industrials i geografia humana

L'article presenta una visió global de la problemitica dels residus industrials des d'una doble perspectiva que destaca el caracter sbcioterritorial dels impactes, associats a la seva preskncia en el medi, i els conflictes que s'esdevenen entorn a les opcions de gestió actualment vigents. Després d'examinar els residus en relació amb la producció industrial, i la producció i "eliminació", dels residus industrials des de la dimensió territorial, es fa un reph de les polítiques de gestió, sobre la base de diferents palsos productors, i s'estudien les implicacions socio-polítiques dels models de gestió, tot centrant-se en l'analisi de les iniciatives ciutadanes alemanyes i de les mobilitzacions a Catalunya en resposta al cepla Director per a la Gestió dels Residus Industrials a Catalunyau. A les conclusions s'enceta una reflexió a l'entorn de la recerca en Geografia Humana i l'anilisi dels residus industrials, i es plantegen les implicacions tebriques i epistemologiques de cara a una visió social dels problemes ambientals.

Materials selection for superheater tubes in municipal solid waste incineration plants

Corrosion reduces the lifetime of municipal solid waste incineration (MSWI) superheater tubes more than any other cause. It can be minimized by the careful selection of those materials that are most resistant to corrosion under operating conditions. Since thousands of different materials are already known and many more are developed every year, here the selection methodology developed by Prof. Ashby of the University of Cambridge was used to evaluate the performance of different materials to be used as MSWI superheater tubes. The proposed materials can operate at steam pressures and temperatures over 40 bars and 400ºC, respectively. Two case studies are presented: one makes a balanced selection between mechanical properties and cost per thermal unit; and the other focuses on increasing tube lifetime. The balanced selection showed that AISI 410 martensitic stainless steel (wrought, hard tempered) is the best candidate with a good combination of corrosion resistance, a relatively low price (0.83-0.92 e/kg) and a good thermal conductivity (23-27 W/m K). Meanwhile, Nitronic 50/XM-19 stainless steel is the most promising candidate for longterm selection, as it presents high corrosion resistance with a relatively low price (4.86-5.14 e/kg) compared to Ni-alloys.

El efecto residual inmunosupresor de la ciclofosfamida no es necesario para evocar la respuesta inmunosupresora condicionada

El objetivo es comprobar si el efecto residual inmunodepresor de la ciclofosfamida contribuye a la evocación de la respuesta de anticuerpos condicionada. Se condicionaron ratones no consanguíneos, machos, con el estímulo condicionado sacarina al 0,15% y con el estímulo incondicionado ciclofosfamida, a 50 y 250 mg/kg. A los 4 días del condicionamiento con 50 mg/kg de ciclofosfamida, o a los 14 días del condicionamiento con 250 mg/kg de ciclofosfamida, los ratones se inmunizaron con glóbulos rojos de rata y, a continuación, bebieron la disolución de sacarina. Se comprobó que i) la dosis más baja de ciclofosfamida no generó efecto residual, mientras que la dosis más alta si, y ii) en ningún caso, la presentación de sacarina disminuyó la respuesta de anticuerpos anti-glóbulos rojos de rata. Se concluye que no se produjo condicionamiento de la respuesta de anticuerpos, tanto si el efecto residual de la ciclofosfamida está presente, como si está ausente.

Efficiency and environmental regulation: a 'complex situation'

Production of desirable outputs is often accompanied by undesirable by products that have damaging effects on the environment, and whose disposal is frequently regulated by public authorities. In this paper, we compute directional technology distance functions under particular assumptions concerning disposability of bads in order to test for the existence of what we call ‘complex situations’, where the biggest producer is not the greatest polluter. Furthermore, we show that how in such situations, environmental regulation could achieve an effective reduction in the aggregate level of bad outputs without reducing the production of good outputs. Finally, we illustrate our methodology with an empirical application to a sample of Spanish tile ceramic producers.

On the regional impact of public capital formation in Spain

The objective of this paper is to investigate, in a methodologically consistent manner, the regional effects of public capital formation and the possible existence of regional spillover effects in Spain. The empirical results are based on VAR estimates at both the aggregate and regional levels using output, employment, and private capital, as well as different measures of public capital. Empirical results suggest that public capital affects output positively at the aggregate level as well as in all but one region. For most regions, the effects of public capital installed in the region itself are important but the spillover effects induced from public capital installed elsewhere are also very important. In fact, the spillover effects account for over half of the total effects of public capital formation in Spain. Furthermore, these spillover effects have a clear geographical pattern in that they tend to be more important in the peripheral regions of the country. We also find that relative to their share of the Spanish output, the biggest beneficiaries of public capital formation are the largest regions in the country. This suggests that public capital formation has contributed to concentration of output in these regions. Finally, in terms of the effects of public capital formation on the private inputs we find that both private capital and employment are affected positively at the aggregate level as well as for most of the regions. Nevertheless, the effects on private capital seem to be larger. Also, the spillover effects are very important for private capital but not for employment. This reflects a great degree of dynamism and mobility in the capital markets as opposed to the labor markets.

Inter-regional redistribution through infrastructure investment: tactical or programmatic?

In this paper we analyze the effects of both tactical and programmatic politics on the inter-regional allocation of infrastructure investment. We use a panel of data for the Spanish electoral districts during the period 1964-2004 to estimate an equation where investment depends both on economic and political variables. The results show that tactical politics do matter since, after controlling for economic traits, the districts with more ‘Political power’ still receive more investment. These districts are those where the incumbents’ Vote margin of victory/ defeat in the past election is low, where the Marginal seat price is low, where there is Partisan alignment between the executives at the central and regional layers of government, and where there are Pivotal regional parties which are influential in the formation of the central executive. However, the results also show that programmatic politics matter, since inter-regional redistribution (measured as the elasticity of investment to per capita income) is shown to increase with the arrival of the Democracy and EU Funds, with Left governments, and to decrease the higher is the correlation between a measure of ‘Political power’ and per capita income.

Air services on thin routes: Regional versus low-cost airlines

An examination of the impact in the US and EU markets of two major innovations in the provision of air services on thin routes - regional jet technology and the low-cost business model - reveals significant differences. In the US, regional airlines monopolize a high proportion of thin routes, whereas low-cost carriers are dominant on these routes in Europe. Our results have different implications for business and leisure travelers, given that regional services provide a higher frequency of flights (at the expense of higher fares), while low-cost services offer lower fares (at the expense of lower flight frequencies). Keywords: air transportation; regional jet technology; low-cost business model; thin markets. JEL Classification Numbers: L13; L2; L93.

Regional flows of domestic tourism in Spain = Flujos regionales del turismo doméstico en España

The paper analyses the regional flows of domestic tourism that took place in Spain in year 2000, contributing to the state of knowledge on tourism required by authorities and private firms when faced with decision making, for example, for regional infrastructure planning. Although tourism is one of the main income-generating economic activities in Spain, domestic tourism has received little attention in the literature compared to inbound tourism. The paper uses among others, gravitational model tools and concentration indices, to analyse regional concentration of both domestic demand and supply; tourism flows among regions, and the causes that may explain the observed flows and attractiveness between regions. Among the most remarkable results are the high regional concentration of demand and supply, and the role of population and regional income as explanatory variables. Also remarkable are the attractiveness of own region and neighbour ones, and that domestic tourism may be acting as a regional income redistributing activity
