Economic and legal analysis of mandatory non-recourse mortgages with applications to Spain

“The liquidity crisis of the Spanish banks is largely due to the lack of confidence of foreign investors and, therefore, the changes that occur in the legislation should not affect the credibility, stability, legal certainty, predictability that markets expect”.Sergio Nasarre (2011)In the current situation of economic crisis, many people have found they can no longer pay back the mortgage loans that were granted to them in order to purchase a dwelling. It is for this reason that, in light of the economic, political and social problems this poses, our paper studies the state of the Spanish real-estate system and of foreclosure, paying special attention to the solution that has been proposed recently as the best option for debtors that cannot make their mort-gage payments: non-recourse mortgaging. We analyze this proposal from legal and economic perspectives in order to fully understand the effects that this change could imply. At the same time, this paper will also examine several alternatives we believe would ameliorate the situation of mortgage-holders, among them legal reforms, mortgage insurance, and non-recourse mortgaging itself.

The External validity in economic experiments

One of the most important questions regarding experimental economics is the external validity of laboratory experiments. This paper goes through a study that tests the generalizability of a Dictator Game as a laboratory analogue for a naturally occurringdecision-making context of teacher absenteeism. Because lab and naturally-occurring environments systematically differ we then discuss other factors that might strongly affect the choices that individuals make. We conclude that the dichotomy drawn between labexperiments and data collected from natural settings is a false one. A combination of the two would provide deeper and better insights than either separately.

Estudi de les aigües salines a la conca del riu Llobregat i Cardener : implicacions ambientals

L’increment de la salinitat a les aigües subterrànies a prop de la zones de les explotacions mineres salines representa un problema ambiental amb moltes implicacions socio-econòmiques. La part mitja de la conca del riu Llobregat i Cardener és un clar exemple d’aquesta problemàtica. En molts casos l’origen de la salinitat és dubtós, ja que pot provenir del contacte de l’aigua de l’aqüífer amb formacions geològiques salines naturals o per l’afectació de les escombreres produïdes per l’explotació minera de potasses que es troba en aquesta regió. L’objectiu d’aquest treball és demostrar que el Ra pot ser un bon traçador per determinar l’origen de la salinitat de les aigües i complementar les analítiques químiques elementals i dels isòtops del sofre i de l’oxigen del sulfat (δ34SSO4 i δ18OSO4). La presència dels diversos isòtops del Ra en les aigües subterrànies dependrà de la geologia i del temps de residència de l’aigua dins l’aqüífer. L’anàlisi de 12 mostres de la comarca indica que el 226Ra és el millor dels isòtops del Ra que permet diferenciar l’origen de les aigües subterrànies.

Análisis, zonificación y manejo de la estación de monitorización Madre Selva

Este artículo es la síntesis del trabajo realizado en Costa Rica en la finca “Madre Selva” donde se encuentra una estación de monitoreo de aves. Los objetivos finales del proyecto son el análisis socioambiental, la zonificación de toda el área de la finca y el desarrollo de las vías y programas de manejo para que todas las actividades realizadas sean respetuosas con el medio ambiente. Madre Selva ocupa una superficie de 160ha y está situada en la “Reserva Forestal Los Santos” a una altura de 2600m. En esta superficie se han registrado un total de 200 especies diferentes de avifauna. Las dos actividades que se llevan a cabo son la monitorización como actividad científica y la ganadería como actividad económica. La razón por la cual se ha efectuado este estudio es la conservación del ecosistema para que las aves habiten en sus condiciones naturales y la actividad científica se realice de manera efectiva. La zonificación de Madre Selva refleja los diferentes usos del suelo y funciones del territorio. Concretamente, la finca ha quedado dividida en 7 zonas descritas con sus valores y sus correspondientes vías de manejo. Finalmente, se describen los programas de manejo que se llevan a cabo actualmente y se proponen nuevos programas así como propuestas de mejora. Se destaca la oportunidad de desarrollar nuevas actividades como la educación ambiental y el ecoturismo.

Iron mining in Goa (India) : an interdisciplinary study

En aquest article es presenten breument els diferents capítols d’un treball interdisciplinari per tal d’entendre el context de prohibició de la mineria de ferro a Goa a finals del 2012 i proporcionar la informació necessària per tal d’orientar i gestionar la presa de decisions sobre l’activitat minera en un futur. Els sis primers capítols consisteixen en l’estudi del medi abiòtic, medi biòtic, fluxos de materials, aspectes socials, aspectes econòmics i finalment aspectes polítics. En canvi, en els dos últims capítols s'avaluen i es gestionen els impactes ambientals de la mineria mitjançant, per una banda, una anàlisi DPSIR i, d'altra banda, es proposen tres escenaris per integrar les diferents variables i fomentar la participació en la presa de decisions. S’ha dut a terme una extensa recerca mitjançant la recopilació de dades, entrevistes i visites a les zones d’estudi d’interès per tal d’entendre el conflicte de la mineria a Goa.

Flora ornamental de Cerdanyola del Vallès, idoneïtat respecte les al·lèrgies i mesures pal·liatives

El pol·len de plantes alliberat durant la pol·linització pot produir al·lèrgies a persones sensibles amb tendència ascendent en el temps, provocant malestar i elevades pèrdues econòmiques. La mala planificació en flora ornamental urbana és, en part, responsable; aquest estudi identifica, ajudant-se de plànols de simple interpretació, els principals problemes d’aquesta en relació a les al·lèrgies en Cerdanyola. S’observa una elevada presència de gèneres amb alta al·lerginicitat, molts concentrats en determinades localitzacions, essent especialment perillosos en març i abril, i una sobreplantació d’Acer negundo. Millorar la qualitat de vida dels afectats passa principalment per disminuir el nombre d’espècies altament al·lergògenes prioritàriament en les localitzacions amb més perill, tasca que ha de ser idealment realitzada per un equip d’experts.

Pla de gestió de senglars (Sus scrofa) en zones altament antropitzades. Parc Natural de la Serra de Collserola

By studying documents that define the species, as management experiences in Spain and the rest of the world, we have designed a new management plan. This Plan incorporates guidelines for cooperation and networking, as the newest techniques and technologies in the field of wildlife management. During this project, has highlighted the need for a protocol to monitor the effects caused by the animals, in order to define and optimize the actions and resources to use.

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.

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.

Els suburbia al Mediterrani de la Hispania Citerior, o els termòmetres de la salut de l’Imperi

Reflexión sobre los suburbios costeros de las principales ciudades de la provincia Hispania Citerior en base a criterios de dinamismo económico, concebidos como la causa principal de la aparición de las áreas periurbanas. Los procesos expansivos o regresivos se interrelacionan con la vitalidad de las actividades portuarias, determinantes en el crecimiento periurbano, o en la génesis de núcleos alejados de las ciudades ubicadas a escasa distancia de la costa. Este documento intenta aportar los rasgos comunes propios de la uniformidad urbanística del período altoimperial, y que desaparecieron en la antigüedad tardía como consecuencia de los procesos específicos de cada núcleo urbano, condicionado por la viabilidad de su modelo económico y su rol geoestratégico. De este modo, el análisis de las zonas suburbiales se manifiesta como el principal índice de prosperidad económica y urbanística. No en vano, estas mantuvieron su funcionalidad en época tardía, mientras la ciudad altoimperial fue desestructurándose.

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
