[Es] En este trabajo se presentan los resultados de un estudio piloto realizado en la Comunidad Autónoma del País Vasco con una muestra de sujetos con edades comprendidas entre 12 y 40 años. Dentro de una investigación más amplia donde se pretende relacionar la dieta televisiva y los valores implícitos y explícitos que se perciben en los contenidos televisivos, se exponen algunas diferencias y semejanzas respecto a los hábitos y dieta televisiva de los diferentes grupos de edad. Los datos encontrados nos permiten concluir que los programas más visionados no son los más perniciosos para adolescentes y jóvenes, ni tampoco que el visionado de la televisión impida el desarrollo de otro tipo de actividades.

A menudo, el deslumbramiento de los nuevos medios impide el reconocimiento debido a otras alternativas de comunicación social que, de manera persistente y discreta, han llegado a confundirse con nuestra propia vida. Es el caso de este medio invisible, que bien se merecía un congreso dedicado a la mejor radio y a uno de sus mayores inspiradores, Bertolt Brecht, quien ochenta años atrás imaginó una radio interactiva cuando no existía la tecnología necesaria para hacer realidad su sueño. Hoy como ayer, las voces comunicantes de la radio cuentan mil y una historias que los oyentes siguen como si les fuera la vida en ello. Quizá la radio no esté a la cabeza de las industrias creativas, pero su magia sigue desatando la imaginación y la creatividad de las audiencias. Es por eso, y por su cercanía, que da tanta confianza y es tan querida. Nada más lejos de nuestra intención que la autocomplacencia, un virus tanto o más peligroso que el ruido y la cacofonía radiofónica, que de todo hay en el dial. Los participantes en este encuentro nos hemos conjurado a favor de una radio abierta; hecha con cabeza y corazón, como la vida misma; y más acogedora con los jóvenes creadores, que no lo saben todo de la radio, pero, por eso mismo, están mejor preparados para llevar el ritmo que bailan las neuronas de las nuevas audiencias. Una radio que da la palabra a la gente, sabe escuchar, y no se agota en el ejercicio inútil de escucharse a sí misma.

In this paper we analyse the behaviour of the EU market for CO2 emission allowances; specifically, we focus on the contracts maturing in the Kyoto Protocol's second period of application (2008 to 2012). We calibrate the underlying parameters for the allowance price in the long run and we also calibrate those from the Spanish wholesale electricity market. This information is then used to assess the option to install a carbon capture and storage (CCS) unit in a coal-fired power plant. We use a two-dimensional binomial lattice where costs and profits are valued and the optimal investment time is determined. In other words, we study the trigger allowance prices above which it is optimal to install the capture unit immediately. We further analyse the impact of several variables on the critical prices, among them allowance price volatility and a hypothetical government subsidy. We conclude that, at current permit prices, from a financial point of view, immediate installation does not seem justified. This need not be the case, though, if carbon market parameters change dramatically and/or a specific policy to promote these units is adopted.

An economic expert working group (STECF/SGBRE-07-05) was convened in 2007 for evaluating the potential economic consequences of a Long-Term Management Plan for the northern hake. Analyzing all the scenarios proposed by biological assessment, they found that keeping the F in the status quo level was the best policy in terms of net present values for both yield and profits. This result is counter intuitive because it may indicate that effort costs do no affect the economic reference points. However, it is well accepted that the inclusion of costs affects negatively the economic reference points. In this paper, applying a dynamic agestructured model to the northern hake, we show that the optimal fishing mortality that maximizes the net present value of profits is lower than Fmax.

Most fisheries agencies conduct biological and economic assessments independently. This independent conduct may lead to situations in which economists reject management plans proposed by biologists. The objective of this study is to show how to find optimal strategies that may satisfy biologists and economists' conditions. In particular we characterize optimal fishing trajectories that maximize the present value of a discounted economic indicator taking into account the age-structure of the population as in stock assessment methodologies. This approach is applied to the Northern Stock of Hake. Our main empirical findings are: i) Optimal policy may be far away from any of the classical scenarios proposed by biologists, ii) The more the future is discounted, the higher the likelihood of finding contradictions among scenarios proposed by biologists and conclusions from economic analysis, iii) Optimal management reduces the risk of the stock falling under precautionary levels, especially if the future is not discounted to much, and iv) Optimal stationary fishing rate may be very different depending on the economic indicator used as reference.

Previous research has shown a strong positive correlation between short-term persistence and long-term output growth as well as between depreciation rates and long-term output growth. This evidence, therefore, contradicts the standard predictions from traditional neoclassical or AK-type growth models with exogenous depreciation. In this paper, we first confirm these findings for a larger sample of 101 countries. We then study the dynamics of growth and persistence in a model where both the depreciation rate and growth are endogenous and procyclical. We find that the model s predictions become consistent with the empirical evidence on persistence, long-term growth and depreciation rates.

[En]The present study aimed at investigating the existence of long memory properties in ten developed stock markets across the globe. When return series exhibit long memory, the series realizations are not independent over time and past returns can help predict future returns, thus violating the market efficiency hypothesis. It poses a serious challenge to the supporters of random walk behavior of the stock returns indicating a potentially predictable component in the series dynamics. We computed Hurst-Mandelbrot’s Classical R/S statistic, Lo’s statistic and semi parametric GPH statistic using spectral regression. The findings suggest existence of long memory in volatility and random walk for logarithmic return series in general for all the selected stock market indices. Findings are in line with the stylized facts of financial time series.
