A comparative economic analysis of torrefied pellet production based on state-of-the-art pellets
2017
Abstract Torrefied pellets have fuel properties superior to those of conventional wood pellets and potentially allow greater rates of co-firing and thus larger reductions in net CO 2 emissions. Despite the growing amount of scientific output on torrefaction, the economic feasibility of torrefied pellet production is still a topic of considerable uncertainty. This is an obstacle for decision makers looking to implement sustainable energy policies. This paper compares the economics of torrefied pellets to conventional wood pellets. Working backwards from demonstrated pellet properties, this work attempts to answer the following question: Based on state-of-the-art torrefied pellets, what would…
A novel thermoeconomic analysis under dynamic operating conditions for space heating and cooling systems
2019
Abstract Thermoeconomic analysis allows for a deep understanding of the cost formation process within an energy system, providing insights into the possible routes for improvement. Several thermoeconomic approaches are well-established for application in systems with steady operating conditions, such as power plants, while a limited number of applications to air-conditioning systems in buildings have been proposed, due to the difficulties in dealing with very irregular load profiles and unsteady plant operating conditions. This study investigates the potential of Thermoeconomics as a support for decision making in building energy systems, proving its capability to identify trade-offs betwee…
A Simulation Analysis of the Microstructure of an Order Driven Financial Market with Multiple Securities and Portfolio Choices
2005
In this paper we propose an artificial market where multiple risky assets are exchanged. Agents are constrained by the availability of resources and trade to adjust their portfolio according to an exogenously given target portfolio. We model the trading mechanism as a continuous auction order-driven market. Agents are heterogeneous in terms of desired target portfolio allocations, but they are homogeneous in terms of trading strategies. We investigate the role played by the trading mechanism in affecting the dynamics of prices, trading volume and volatility. We show that the institutional setting of a double auction market is sufficient to generate a non-normal distribution of price changes…
Devenir chercheur ou enseignant chercheur : le goût pour la recherche des doctorants à l'épreuve du marché du travail
2016
Faire une thèse pour devenir chercheur ou enseignant-chercheur est souvent considéré comme un parcours difficile dont le résultat est incertain. Plus que dans d’autres pays, les diplômés de doctorat en France connaissent de fortes difficultés de stabilisation sur le marché du travail. Notre recherche s’interroge sur les raisons qui conduisent les jeunes à obtenir un doctorat puis à choisir une carrière de chercheur ou d’enseignant-chercheur et enfin, à s’y stabiliser. À partir d’une enquête du Céreq, nos résultats montrent que l’intérêt pour la recherche qu’ils ont manifesté dès le début des études supérieures et le capital social vont fortement structurer leur parcours universitaire et pro…
Transport infrastructures, spillover effects and regional growth: evidence of the Spanish case
2005
The impact of transport infrastructures on the economic growth of both regions and sectors, distinguishing among modes of transport, is analysed. An attempt is also made to capture the spillover effects associated with transport infrastructures. Two different methodologies are used: the first adopts an accounting approach based on a regression on indices of total factor productivity; the second uses econometric estimates of the production function. Very similar elasticities are obtained with both methodologies for the private sector of the economy, both for the aggregate capital stock of transport infrastructures and for the various types of infrastructure. However, the disaggregated result…
La Psicologga Financiera Y La Estructura De Capital De Las Pymes (The Financial Psychology and SME's Capital Structure)
2015
Spanish Abstract: El objetivo de este trabajo es estudiar las Teorias de la Estructura de Capital para detectar aquellas variables que pueden determinar el nivel de endeudamiento elegido por una empresa. Para ello se examina la naturaleza y dificultades financieras de las pymes, y se realiza una comparativa con la piramide de Maslow para mostrar la vertiente psicologica de la estructura de capital de las companias. Estos argumentos posteriormente son contrastados con un analisis empirico de las pymes de la Comunidad Valenciana, complementado con varias entrevistas a pymes valencianas para conocer la opinion y experiencia de las personas mas cercanas a estas. Entre otras cosas, se concluye q…
La formation du capital et le financement de l'amortissement chez Walras et Keynes
1985
L'explication de la formation du capital dans les systèmes de Walras distingue les entrepreneurs des capitalistes. Les premiers organisent la production, les seconds épargnent une partie de leur revenu tiré de la rémunération des services producteurs. Walras distingue essentiellement trois facteurs de production, le travail, la terre et le capital. (...)
Building a model of corporate social responsibility in the old industrial region(in the case of Upper Silesia): a sociological perspective
2009

Evaluación de las tarifas de las pensiones de accidentes de trabajo y enfermedades profesionales (2011-2015)
2017
Este trabajo analiza si las tarifas que se aplican para la determinación del denominado capital coste de pensiones derivadas de los accidentes de trabajo y enfermedades profesionales son las adecuadas. A partir de los datos de la Muestra Continua de Vidas Laborales y de la evolución de la longevidad de la población general en España, se estiman tablas de mortalidad para las contingencias de viudedad e invalidez que, combinadas con los parámetros económicos y financieros apropiados, permiten construir las bases técnicas actuarialmente justas para cada uno de los años objeto de análisis. Los resultados obtenidos sugieren que las tarifas aplicadas en el periodo 2011- 2014 han sido muy superior…
