“¿Cómo ha ido la Feria?” Estimación del impacto económico de acontecimientos turístos: tres estudios de caso

Los acontecimientos pueden contribuir al desarrollo turístico de una ciudad y beneficiar a sus habitantes y empresas. Sin embargo, para poder diseñar los acontecimientos correctamente, es necesario comprender qué características determinan su impacto económico. Esta investigación pretende contribuir a tal entendimiento mediante la estimación y comparación del impacto económico de tres acontecimientos. Para estimar el impacto económico adoptamos un modelo básico de tres factores: (1) número de visitantes por (2) gasto medio por turista por (3) multiplicador. Primero estimamos el número de visitantes particulares y profesionales mediante diversos sistemas de conteo, encuestas personales e información suministrada por el organizador de los eventos. En segundo lugar, obtuvimos los importes y componentes del gasto de los visitantes por medio de una encuesta; también contamos los gastos de organización de los eventos a partir de sus respectivos presupuestos. Y, tercero, utilizamos multiplicadores de tablas input-output para analizar el impacto de los gastos directos sobre la producción, el valor añadido y el empleo y su distribución entre sectores económicos. Además, calculamos y comparamos ratios de rentabilidad de los tres eventos y dimos recomendaciones para aumentar su impacto económico.

The economics of infertility

Infertility is a growing issue that affects thousands of Spanish couples; increasingly there are more and more people who cannot raise a family by themselves. Instead they have to resort to ART, adoption -local or international- or surrogacy abroad, a practice that many couples consider but that isn’t legalized in Spain. In this paper we have broken down each option in detail by analysing the market, differentiating its variants and specific steps, calculating its “price” and suggesting possible improvements that could be made from an economic perspective. We end our paper with the “SWOT” analysis of a hypothetical surrogacy market in Spain by calculating an estimated price, using the US as a reference, and the degree of acceptance it would have, based on the results of random surveys.

Evolució i anàlisi del metabolisme ambiental del polígon industrial. El cas de Maó (Menorca)

El polígon industrial de Maó, POIMA, és un dels principals motors econòmics de l’illa de Menorca. La Universitat Autònoma de Barcelona (UAB) en col·laboració amb l’Observatori Socioambiental de Menorca (OBSAM), ha fet un projecte d’anàlisi de l’evolució històrica i del metabolisme actual del polígon. L’estudi es centra en 5 vectors; usos del sòl, energètic, hídric, materials i mobilitat dels quals les dades han estat obtingudes a partir d’enquestes, entrevistes a les empreses i observacions directes semi-quantitatives. Com a resultat es presenten diverses propostes de millora per augmentar l’eficiència de POIMA, analitzant el potencial d’autosuficiència energètic i hídric, reduint l’impacte ambiental i reutilitzant els residus com a recursos entre empreses, sinèrgies.

European Integration: Partisan Motives or Economic Benefits?

In this paper we examine the influence of economic factors to explain partisan support for European integration over the last three decades. We find that partisan support is larger in `poorer' countries with direct economic bene fits from EU membership. On the contrary, parties in countries aff ected by the Maastricht criteria are more Euro-sceptical. Moreover, we find weak evidence for larger partisan support in countries with more developed welfare states, and that the support for European integration fluctuates in parallel with the business cycle. Finally, our results indicate that the importance of economic factors in determining partisan support for European integration has grown in recent periods. JEL classi fication: F15, F42, F53, F55, H60. Key words: European Integration; Partisan Ideology; Maastricht Criteria; European Budget; Benefi ts from Trade.

Demand-based structural change and balanced economic growth

[eng] We analyze the equilibrium of a multi-sector exogenous growth model where the introduction of minimum consumption requirements drives structural change. We show that equilibrium dynamics simultaneously exhibt structural change and balanced growth of aggregate variables as is observed in US when the initial intensity of minimum consumption requirements is sufficiently small. This intensity is measured by the ratio between the aggregate value of the minimum consumption requirements and GDP and, therefore, it is inversely related with the level of economic development. Initially rich economies benefit from an initially low intensity of the minimum consumption requirements and, as a consequence, these economies end up exhibiting balanced growth of aggregate variables, while there is structural change. In contrast, initially poor economies suffer from an initially large intensity of the minimum consumption requirements, which makes the growth of the aggregate variables unbalanced during a very large period. These economies may never exhibit simultaneously balanced growth of aggregate variables and structural change.

Nonequilibrium phase transition in a model for the propagation of innovations among economic agents

We characterize the different morphological phases that occur in a simple one-dimensional model of propagation of innovations among economic agents [X. Guardiola et al., Phys. Rev E 66, 026121 (2002)]. We show that the model can be regarded as a nonequilibrium surface growth model. This allows us to demonstrate the presence of a continuous roughening transition between a flat (system size independent fluctuations) and a rough phase (system size dependent fluctuations). Finite-size scaling studies at the transition strongly suggest that the dynamic critical transition does not belong to directed percolation and, in fact, critical exponents do not seem to fit in any of the known universality classes of nonequilibrium phase transitions. Finally, we present an explanation for the occurrence of the roughening transition and argue that avalanche driven dynamics is responsible for the novel critical behavior.

Economic evaluation of the levonorgestrel-releasing intrauterine system for the treatment of dysfunctional uterine bleeding in Spain

To compare the cost and effectiveness of the levonorgestrel-releasing intrauterine system (LNG-IUS) versus combined oral contraception (COC) and progestogens (PROG) in first-line treatment of dysfunctional uterine bleeding (DUB) in Spain. STUDY DESIGN: A cost-effectiveness and cost-utility analysis of LNG-IUS, COC and PROG was carried out using a Markov model based on clinical data from the literature and expert opinion. The population studied were women with a previous diagnosis of idiopathic heavy menstrual bleeding. The analysis was performed from the National Health System perspective, discounting both costs and future effects at 3%. In addition, a sensitivity analysis (univariate and probabilistic) was conducted. RESULTS: The results show that the greater efficacy of LNG-IUS translates into a gain of 1.92 and 3.89 symptom-free months (SFM) after six months of treatment versus COC and PROG, respectively (which represents an increase of 33% and 60% of symptom-free time). Regarding costs, LNG-IUS produces savings of 174.2-309.95 and 230.54-577.61 versus COC and PROG, respectively, after 6 months-5 years. Apart from cost savings and gains in SFM, quality-adjusted life months (QALM) are also favourable to LNG-IUS in all scenarios, with a range of gains between 1 and 2 QALM compared to COC and PROG. CONCLUSIONS: The results indicate that first-line use of the LNG-IUS is the dominant therapeutic option (less costly and more effective) in comparison with first-line use of COC or PROG for the treatment of DUB in Spain. LNG-IUS as first line is also the option that provides greatest health-related quality of life to patients.

Cultural events and tourist development in Catalonia (Spain)

From the point of view of local development cultural tourism events represent an opportunity since they are distributed homogeneously by the Catalan territory and are experiencing a vertiginous growth as a way to differentiate the existing supply. In our study a sample of 264 telephone surveys made to organizers of events in Catalonia has been compiled, with the purpose of characterizing the existing supply, thematic typologies, management models, commercialization inputs and economic impact. The results allow us to characterize events from the point of view of their tourist potential. Finally some recommendations are set out to develop future tourism policies based on events according to product differentiation, seasonality, competitiveness and creativity.

Impact of quality and environmental investment on business competitiveness and profitability: The case of travel agencies

Few studies have examined the combined effect of implementing quality and environmental management within the service sector. This void is more evident if we focus on segments in which small businesses predominate and even more so if we look for highly competitive sectors that are very variable and that have high business mortality. After analysing 198 surveys of Spanish travel agency managers using structural equations, it can be concluded that practices of quality management have a significant direct impact on business competitiveness but not on this business's financial results, at least directly. However, there is a significant relationship between environmental management practices and economic benefits. This article suggests that commitment to quality and the environment can allow small businesses in the service sector to have a competitive advantage that will separate surviving and ceased operations, particularly in sectors that are rapidly evolving and highly competitive.

Interrelation among Economic Growth, Income Inequality, and Fiscal Performance: Evidence from Anglo-Saxon Countries

The interrelation among economic growth, income inequality, and fiscal performance is very complex. The paper provides the analysis of the interrelations among these variables jointly by the structural VAR methodology, examining also transmission channels among them. This approach allows exploring dynamic interactions among them and feedback effects on each other. The empirical analysis is implemented for the Anglo-Saxon countries, the UK, the USA, and Canada. We find that income inequality has negative effect on economic growth in the case of the UK. The effect is positive in the cases of the USA and Canada. The increase in income inequality worsens fiscal performance for all the countries

Rentabilidad económica del regadío de los canales de Urgell (Lleida, España)

En este trabajo se presentan resultados de indicadores de eficiencia productiva y económica en el uso del agua de riego en el área regable de los Canales de Urgell (Lleida). Se ha realizado un estudio de costes, ingresos, márgenes brutos y beneficios de los principales cultivos de la zona: trigo, maíz, alfalfa, manzana var. Golden, pera var. Conference y pera var. Blanquilla, todos ellos mediante riego por superficie. La recogida de datos proviene de la realización de entrevistas a 24 agricultores de la zona de estudio. Los resultados muestran que los frutales presentan mayores índices de eficiencia productiva, entre 1,9 y 6,6 kg/m3 de agua aplicada, respecto a los cultivos extensivos, que presentan un índice entre 0,7 y 1,8 kg/m3. En cuanto a los índices de eficiencia económica, también se han obtenido valores más elevados en el caso de los frutales, entre 0,4 y 1,7 €/m3, frente a 0,06 – 0,20 €/m3 en extensivos para el ratio Margen bruto / agua aplicada, y entre 0,3 y 1,3 €/m3 para el ratio Beneficio / agua aplicada en frutales, frente a 0,04 – 0,16 de los extensivos.

The economic relevance of climate variables in agriculture: the case of Spain

We estimate how climate variables affect price and acreage of productive farmland using the Ricardian approach. Furthermore, we use our estimations to evaluate the joint effects of possible cli- mate changes within the time horizon of 2010 and 2050. Our results show that the price of rainfed land in Spain tends to increase but rainfed acreage decreases. On the other hand, the effect on irrigated farmland price and acreage presents some mixed results, however, in the long run the dominant pattern is clearly increasing for both prices and acreage.

The economic relevance of climate variables in agriculture: The case of Spain

We estimate the impact of the different climate variables on the value of Spanish farmland. We distinguish between irrigated and non-irrigated lands and use data on temperature, precipitations, physical and socioeconomic characteristics to measure these effects on farm prices and in the number of hectares of farmland. We conclude presenting the main results of our analysis, region by region, and examining the policies that could be more effective to prevent undesired effects.
