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.

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.
