Rail freight transport and demand requirements : an analysis of attribute cut-offs through a stated preference experiment
2014
This paper analyses the choice between road and rail in Spain where rail market share for freight is still residual. Discrete choice models are estimated with data obtained through a two-phase fieldwork, thus allowing us to carry out a stated preference efficient design for each interviewee. We analyse the existence of attribute cut-offs and the presence of a segment of the population with a zero value of frequency. Our results show that ignoring the existence of cut-offs and segments of the population with polarised valuations can lead to erroneous conclusions in terms of the possibilities of rail for absorbing significant quota.

Macro-uncertainty and financial stress spillovers in the Eurozone
2020
Abstract This paper studies macro-uncertainty and financial distress spillovers within the Eurozone. We propose a novel methodology to derive the indices of spillovers, by using a Global Vector autoregressive model fitted to data sampled at mixed-frequencies. We find that macro-uncertainty and financial stress are relatively disconnected in the Eurozone. We also show that connectedness between core and periphery Eurozone countries mainly operates through financial stress and it decreases since the outbreak of the Eurozone sovereign debt crisis (with an increasing role played by peripheral countries). As a result, investors and policymakers should monitor separately macro-uncertainty and fin…
The Classical Notion of Competition Revisited
2013
This article seeks to fill a lacuna within classical economics concerning the process of market price determination in situations of market disequilibrium. To this aim, first we distinguish the classical notion of free competition from the Walrasian notion of perfect competition and we argue that the latter is beset with some theoretical difficulties alien to the former. Second, we reconstruct in some detail Smith’s and Marx’s views concerning market price determination and show that Marx’s extensive use of metaphors and numerical examples foreshadows the modern taxonomy of buyers’ market, sellers’ market, and mixed strategy equilibrium in the capacity space of a standard Bertrand duopoly m…
Multiproduct trading with a common agent under complete information: Existence and characterization of Nash equilibrium
2014
This paper focuses on oligopolistic markets in which indivisible goods are sold by multiproduct firms to a continuum of homogeneous buyers, with measure normalized to one, who have preferences over bundles of products. Our analysis contributes to the literature on private, delegated agency games with complete information, extending the insights by Chiesa and Denicolò (2009) to multiproduct markets with indivisibilities and where the agent's preferences need not be monotone. By analyzing a kind of extended contract schedules -mixed bundling prices- that discriminate on exclusivity, the paper shows that efficient equilibria always exist in such settings. There may also exist inefficient equil…
ANTERIOR OPEN BITE TREATED WITH E F APPLIANCE: A CASE REPORT
2014
Aim. Current trends in pediatric orthodontics aim to identify incorrect development of occlusion and medium/lower facial third as early as possible. Functional appliances are a popular type of device used for treating malocclusion in patients who are growing. Among the functional orthodontic devices intended for this purpose, “Education Functional” is highlighted. It was developed by Dr. Daniel Rollet. In fact, in the occlusal alterations, early preventive treatment with elastodontic devices resulted in avoiding dysfunctional forces from acting on the skeletal pattern, thus reaching a balance between bone basis and muscular components. This report describes a clinical case of a patient (9-y…
La metodología de la Flipped Classroom (FC) en la práctica didáctica de los docentes universitarios. Hacia una definición del modelo didáctico a part…
2022
El trabajo de investigación que se presenta aborda el tema de la implementación del Flipped Classroom, o clase invertida, en el contexto universitario. Flipped Classroom es un método formativo activo, que consiste en invertir los tiempos y espacios de aprendizaje. Al implementarlo, el profesor prepara y proporciona al alumnado los contenidos a estudiar con antelación, de manera que, en el tiempo de clase, hay más posibilidades para hacer ejercicios y practicar los conceptos aprendidos durante el autoestudio. Además, en este proceso juega un papel fundamental el feedback que el docente da a sus alumnos sobre su nivel de comprensión, así como los resultados del aprendizaje y los comentarios q…
