Aspectes econòmics de l'evolució del sistema públic d'ensenyament superior a Catalunya, 1985-1992

L'educació superior espanyola ha sofert un procés d'expansió generalitzat a partir de la segona meitat de la decada deis vuitanta. Malgrat aixo, aquesta expansió no pot ser analitzada conjuntament, ates que durant el mateix període es fan efectives les transferencies de competencies en materia d'educació a set comunitats autonomes que comencen a dur a terme polítiques universitaries no sempre concurrents. En aquest article abordarem el model catala d'expansió úniversitaria i el seu finançament, fent emfasi en els problemes derivats dé l'expansió i les seves possibles solucions. Per fer-ho, utilitzarem la següent estructura: en primer lloc, en l'apartat 2 es descriuen els elements basics del procés d'expansió (especialment la creació de les cinc noves universitats) i la situació resultant tal i com es presenta en l'actualitat. Sense aquestes descripcibns no cobrarien sentit les analisis més específiques sobre el finançament, que es presenten en els apartats 3 i 4.

Signalling and Productivity Effects of Overeducation: Is It Really a Waste of Resources?

Overeducation raises concerns that governments may be overinvesting in education. To inform the debate, this paper studies the impact of overeducation on productivity. We advance the literature by considering that returns to overeducation may be due both to productivity and signalling effects. To disentangle both effects, we apply Wolpin’s (1977) methodology and compare the rates of return of screened (employed) and unscreened (selfemployed) workers. To overcome well-known endogeneity problems due to unobserved heterogeneity, we estimate a panel with individual and employment-status fixed effects. Our results show that signalling effects are relevant and that overeducation does not carry a productivity penalty. Keywords: Overeducation, signalling model, human capital model, unobserved heterogeneity. JEL classification: I20, J24, J31.

Why do we ignore risk in schooling decisions?

While uncertainty abounds in almost any decision on investment in schooling, it is mostly ignored in research and virtually absent in labour economics tekst books. This paper documents the scope for risk, discusses the tough disentanglement of heterogeneity and risk, surveys the analytical models, laments the absence of a good workhorse model and points out the challenges worth tackling: document ex ante risk that investors face, develop a tractable and malleable analytical model and integrate the option of consumption smoothing in analytical and empirical work. Hedging labour market risk in the stock market can be safely ignored.

Financiación de la formación: inicial, ocupacional y continua

La formación, en su vertiente inicial, ocupacional y continua se considera un eje fundamental para el correcto funcionamiento del mercado de trabajo, para la promoción personal y profesional de los trabajadores y como factor esencial para la competitividad de las empresas y la calidad de los servicios y los productos. La importancia del argumento anterior obliga a analizar las principales características de organización y financiación del sistema español de formación, sin olvidar la función de apoyo y complemento de las políticas comunitarias en este ámbito

The private and fiscal returns to schooling and the effect of public policies on private incentives to invest in education: a general framework and some results for the EU

This paper develops a comprehensive framework for the quantitative analysis of the private and fiscal returns to schooling and of the effect of public policies on private incentives to invest in education. This framework is applied to 14 member states of the European Union. For each of these countries, we construct estimates of the private return to an additional year of schooling for an individual of average attainment, taking into account the effects of education on wages and employment probabilities after allowing for academic failure rates, the direct and opportunity costs of schooling, and the impact of personal taxes, social security contributions and unemployment and pension benefits on net incomes. We also construct a set of effective tax and subsidy rates that measure the effects of different public policies on the private returns to education, and measures of the fiscal returns to schooling that capture the long-term effects of a marginal increase in attainment on public finances under c

Deficit, human capital and economic growth dynamics

Long-run economic growth arouses a great interest since it can shed light on the income-path of an economy and try to explain the large differences in income we observe across countries and over time. The neoclassical model has been followed by several endogenous growth models which, contrarily to the former, seem to predict that economies with similar preferences and technological level, do not necessarily tend to converge to similar per capita income levels. This paper attempts to show a possible mechanismthrough which macroeconomic disequilibria and inefficiencies, represented by budget deficits, may hinder human capital accumulation and therefore economic growth. Using a mixed education system, deficit is characterized as a bug agent which may end up sharply reducing the resources devoted to education and training. The paper goes a step further from the literature on deficit by introducing a rich dynamic analysis of the effects of a deficit reduction on different economic aspects.Following a simple growth model and allowing for slight changes in the law of human capital accumulation, we reach a point where deficit might sharply reduce human capital accumulation. On the other hand, a deficit reduction carried on for a long time, taking that reduction as a more efficient management of the economy, may prove useful in inducing endogenous growth. Empirical evidence for a sample of countries seems to support the theoretical assumptions in the model: (1) evidence on an inverse relationship betweendeficit and human capital accumulation, (2) presence of a strongly negative associationbetween the quantity of deficit in the economy and the rate of growth. They may prove a certain role for budget deficit in economic growth

Valoració de la qualitat de vida dels familiars de pacients amb fibromiàlgia

Fonament i objectiu: La Fibromiàlgia (FM) és una malaltia reumàtica caracteritzada per dolor generalitzat, que afecta a un tant per cent elevat de la població general , majoritàriament dones i d’etiologia desconeguda, i que pensem que no afecta tan sols als qui la pateixen, sinó que també als seus familiars. En aquest estudi s’han avaluat diferents variables com l’impacte emocional, la vida social, aspectes econòmics i laborals i altres activitats en familiars de primer grau de pacients amb FM. L’objectiu principal és determinar quin és el grau d’afectació negativa en la seva qualitat de vida. Material i mètodes: Es va fer un estudi observacional clínic a un grup de 27 familiars de 1er grau que convivien a la mateixa casa que els respectius afectats per FM. Se’ls va passar un qüestionari ad- hoc de 16 preguntes tancades, basades en estudis previs , i també una entrevista oberta amb l’objectiu de reforçar les dades estadístiques. Les entrevistes es varen fer a la Unitat de Fibromiàlgia de l’Hospital Santa Maria de Lleida. Resultats: Es va entrevistar a 27 familiars, 85’2 % homes, la majoria de entre 51 – 70 anys (63%). El 85’2 % eren casats, amb estudis primaris el 59’3% i el 88% tenien coneixements sobre la malaltia del familiar afectat. El percentatge de familiars que van opinar que hi havia una minva del grau de felicitats amb la malaltia era del 74’1%. El 85% no havia pensat mai en trencar la relació familiar. El 70% referien canvis en la vida social i relacional arrel del diagnòstic de FM , un 88’9% havien tingut que augmentar l’ajut en tasques domèstiques i el 70’4% patien efectes econòmics negatius arrel de la malaltia. La relació sexual es va veure afectada en un 85% dels casos, en canvi no es varen veure alteracions del son ni de la percepció de salut. Conclusions: El fet de conviure amb una persona afectada de FM suposa pèrdua del grau de felicitat i canvis en la vida social, relacional i sexual amb empitjorament del nivell econòmic.

La Solvencia financiera del asegurador de vida y su relación con el coste de capital

Esta investigación relaciona el margen de solvencia que normativamente deben acreditar los aseguradores de vida con los recursos propios que cualquier empresa debe poseer para poder ejercer su actividad. Analizaremos la incidencia que la remuneración de esos recursos tiene en la propia actividad de comercialización de los seguros demostrando su relación inversa con el tipo de interés garantizado en los contratos. Analizaremos asimismo la incidencia que los eventuales cambios en los tipos de interés pueden tener en la remuneración que puede ofrecerse a esos recursos y propondremos una ecuación que incorpore todos estos aspectos, comprobando que las relaciones que actualmente ofrece la disciplina académica son casos particulares de la ecuación general, casos que demostraremos que incorporan unas hipótesis implícitas bastante restrictivas.

Endeudamiento y ciclos políticos presupuestarios: el caso de los ayuntamientos catalanes

Este trabajo de investigación se dirige sobre el ámbito de los gobiernos locales y su objetivo es el de analizar cuál es el papel del endeudamiento en los ciclos políticos presupuestarios, contrastando si, en la utilización de este instrumento financiero, se da una distribución temporal estratégica en torno a las citas electorales, y si la existencia de estos ciclos puede resultar un factor explicativo del endeudamiento acumulado en los gobiernos locales. Para el contraste empírico se utilizan datos presupuestarios de los ayuntamientos catalanes con una población superior a los 10.000 habitantes, para los cuales disponemos de datos durante el periodo 1988-1999, en total 86 municipios. La metodología empleada está basada en una Prueba T para muestras relacionadas.

Innovación tecnológica y resultado exportador: un análisis empírico aplicado al sector textil-confección español

En los últimos años, la relación entre tecnología y resultado exportador ha sido objeto de algunos estudios centrados en explicar la relación existente entre los distintos indicadores de las actividades tecnológicas y la performance internacional de las empresas. Sin embargo, la mayoría de las investigaciones centradas en este tema tienden a aproximar la estrategia innovadora de una empresa a partir de sus gastos en actividades de I+D cuando, en realidad, el concepto de innovación tecnológica podría resultar más amplio que la mera realización formal de actividades de I+D. En este trabajo en primer lugar se identifican aquellos factores que aproximan, de una forma más exhaustiva, las actividades de innovación tecnológica que realiza una empresa y, en segundo lugar, se averiguará su relación con el resultado exportador de la misma. Los resultados que se obtienen son satisfactorios ya que demuestran que la probabilidad y la intensidad exportadora de las empresas españolas del sector textil-confección dependen no sólo de sus inversiones en I+D, sino también de otras variables vinculadas a su estrategia innovadora.

La Perspectiva biofísica de la relació home-natura: economia ecològica

L'estudi de la relació entre l'activitat econòmica i el medi que ens envolta és antiga en economia. No obstant és cert que darrerament la teoria econòmica sembla haver-la oblidada. És per això que quan sortí la disciplina que avui s’anomena "economia ecològica" va implicar una ruptura amb la manera amb la qual la teoria econòmica convencional descrivia nostra relació amb el medi ambient. El present capítol pretén descriure breument el que creiem són les característiques principals que la fan diferent de la resta de disciplines: la inconmensurabilitat de valors, la seva anàlisi en termes biofísics, i les seves repercussions al nivell de la generació de polítiques, que la fan ser un exemple del que es coneix com a ciència post-normal.

Empiricism in ecological economics: a perspective from complex systems theory

Economies are open complex adaptive systems far from thermodynamic equilibrium, and neo-classical environmental economics seems not to be the best way to describe the behaviour of such systems. Standard econometric analysis (i.e. time series) takes a deterministic and predictive approach, which encourages the search for predictive policy to ‘correct’ environmental problems. Rather, it seems that, because of the characteristics of economic systems, an ex-post analysis is more appropriate, which describes the emergence of such systems’ properties, and which sees policy as a social steering mechanism. With this background, some of the recent empirical work published in the field of ecological economics that follows the approach defended here is presented. Finally, the conclusion is reached that a predictive use of econometrics (i.e. time series analysis) in ecological economics should be limited to cases in which uncertainty decreases, which is not the normal situation when analysing the evolution of economic systems. However, that does not mean we should not use empirical analysis. On the contrary, this is to be encouraged, but from a structural and ex-post point of view.

Ecological economics

Ecological economics is a recently developed field, which sees the economy as a subsystem of a larger finite global ecosystem. Ecological economists question the sustainability of the economy because of its environmental impacts and its material and energy requirements, and also because of the growth of population. Attempts at assigning money values to environmental services and losses, and attempts at correcting macroeconomic accounting, are part of ecological economics, but its main thrust is rather in developing physical indicators and indexes of sustainability. Ecological economists also work on the relations between property rights and resource management, they model the interactions between the economy and the environment, they study ecological distribution conflicts, they use management tools such as integrated environmental assessment and multi-criteria decision aids, and they propose new instruments of environmental policy.
