Estrategias de fijación de precios de las aerolíneas de bajo coste: una aproximación al modelo de la rivalidad ampliada

En la presente tesis doctoral se realiza una aproximación a las estrategias de fijación de precios de las aerolíneas de bajo coste europeas a partir del estudio de su entorno (demanda, proveedores, rivales, productos sustitutos, etcétera). Para ello se emplea el marco del modelo de las cinco fuerzas descrito por Michael Porter. Para su análisis, se utiliza un método combinado de Análisis Factorial (ACP) y datos de panel.

From privatisation to nationalisation: Repsol-YPF, 1999–2012

In April 2012 Argentinean Government nationalized 51% of Repsol shares in YPF. Expropiation of YPF is a new step in a broad list of protectionist and interventionist decisions, such as the nationalization of Aerolíneas Argentinas, nationalization of private pension plans, or the amendments of the Central Bank regulations to make the use of reserves more flexible. Institutions set the rules of the game for citizens and companies, allowing incentives and creating expectations. Nationalization of the above mentioned Argentinean companies has created legal uncertainty bringing a relevant increase in the risk premium as a result. Privatization of YPF and its later nationalization, together with the company shareholder composition, and resulting international disputes will be addressed in this article.
