A Supply Function Competition Model for the Spanish Wholesale Electricity Market

We model the Spanish wholesale market as a multiplant linear supply function competition model. According to the theory, the larger generators should have supply curves for each plant which are to the left of the supply curves of plants owned by smaller generators. We test this prediction for fuel plants using data from the Spanish Market Operator (OMEL) from May 2001 to December 2003. Our results indicate that the prediction of the model holds.

Imperfect Competition

Para quien es de utilidad: •Alumnos de Tª Microeconómica IV, curso 3º LE. •Alumnos de las asignaturas de Tª de Juegos y Organización Industrial del Máster en Economía: Instrumentos del Análisis Económico. Estas notas sobre competencia imperfecta están dedicadas al estudio de estructuras de mercado caracterizadas por la existencia de poder de mercado. Se estudia en primer lugar el monopolio, dedicando una atención especial a los diferentes tipos de discriminación de precios. A continuación se presenta la Tª de juegos no cooperativos y se muestra su utilidad para analizar diferentes fenómenos económicos caracterizados por la interdependencia estratégica. Finalmente, se estudian diferentes modelos de competencia oligopolística y la estabilidad de los acuerdos colusivos.

Reform of Spain's profesional services market: Implementation of the EU Services Directive

The implementation of the European Commission Services Directive initiated the modernization process of services markets within the European Union. The objective was to guarantee the creation of a single market by ensuring the freedom of establishment and circulation. The transposition of the Directive in Spain triggered an initial wave of reforms in the Spanish legal system. A second package of reforms is currently underway, following recommendations by the EC, IMF and OECD, which highlight the relative lack of competition in Spain’s services as one of the major imbalances in its economy, alongside the public deficit and unemployment. Both the implemented and planned reforms represent a major step forward. Nevertheless, the government has recently announced modifications to the draft bill of the Professional Services and Associations Law, which is expected to soon be submitted for parliamentary debate and approval. Taking into consideration modifications already introduced, together with anticipated further changes, it will be important to maintain the main points of the draft bill and to introduce a deeper review of the legal framework for professional services, of the professional associations themselves, and for the activities that are subject to compulsory membership within a professional association. Spain’s territorial map of professional associations must too be redrawn.

A genealogical map of the concept of habit

The notion of information processing has dominated the study of the mind for over six decades. However, before the advent of cognitivism, one of the most prominent theoretical ideas was that of Habit. This is a concept with a rich and complex history, which is again starting to awaken interest, following recent embodied, enactive critiques of computationalist frameworks. We offer here a very brief history of the concept of habit in the form of a genealogical network-map. This serves to provide an overview of the richness of this notion and as a guide for further re-appraisal. We identify 77 thinkers and their influences, and group them into seven schools of thought. Two major trends can be distinguished. One is the associationist trend, starting with the work of Locke and Hume, developed by Hartley, Bain, and Mill to be later absorbed into behaviorism through pioneering animal psychologists (Morgan and Thorndike). This tradition conceived of habits atomistically and as automatisms (a conception later debunked by cognitivism). Another historical trend we have called organicism inherits the legacy of Aristotle and develops along German idealism, French spiritualism, pragmatism, and phenomenology. It feeds into the work of continental psychologists in the early 20th century, influencing important figures such as Merleau-Ponty, Piaget, and Gibson. But it has not yet been taken up by mainstream cognitive neuroscience and psychology. Habits, in this tradition, are seen as ecological, self-organizing structures that relate to a web of predispositions and plastic dependencies both in the agent and in the environment. In addition, they are not conceptualized in opposition to rational, volitional processes, but as transversing a continuum from reflective to embodied intentionality. These are properties that make habit a particularly attractive idea for embodied, enactive perspectives, which can now re-evaluate it in light of dynamical systems theory and complexity research.

Modelling Lipid Competition Dynamics in Heterogeneous Protocell Populations

Recent experimental work in the field of synthetic protocell biology has shown that prebiotic vesicles are able to 'steal' lipids from each other. This phenomenon is driven purely by asymmetries in the physical state or composition of the vesicle membranes, and, when lipid resource is limited, translates directly into competition amongst the vesicles. Such a scenario is interesting from an origins of life perspective because a rudimentary form of cell-level selection emerges. To sharpen intuition about possible mechanisms underlying this behaviour, experimental work must be complemented with theoretical modelling. The aim of this paper is to provide a coarse-grain mathematical model of protocell lipid competition. Our model is capable of reproducing, often quantitatively, results from core experimental papers that reported distinct types vesicle competition. Additionally, we make some predictions untested in the lab, and develop a general numerical method for quickly solving the equilibrium point of a model vesicle population.
