State-Owned Enterprise, Mixed Oligopoly and Entry

We analyse state-owned enterprise (SOE) behaviour under pure and mixed oligopoly. An industry comprising at least two SOEs is shown not to have a symmetric stable equilibrium. This suggests the need for planning in such industries. For mixed oligopoly, we assume that an SOE has a cost disadvantage. When fixed costs must be sunk before entry, free entry implies that, if the SOE cost disadvantage is not too large, the presence of an SOE is immaterial for welfare (there is no welfare gain from privatisation). Similarly, a free-entry all-private oligopoly is welfare-superior to a public monopoly only if endowed with a significant cost advantage.state-owned enterprise, mixed oligopoly, privatisation

Forme necessarie dell’abitare: il ruolo dello spazio pubblico nei contesti informali di Bogotá e Medellín

Gli spazi collettivi rappresentano un beneficio per la comunità, specialmente in quei contesti urbani “informali”, manifestazione fisica del bisogno primordiale dell’abitare. La straordinaria e recente rigenerazione urbana e sociale conquistata dalle città colombiane di Bogotá e Medellín, è un notevole esempio di strategie politiche e progettuali innovative, risultato delle azioni congiunte di politici, professionisti e cittadinanza, che fondano le proprie radici sul riconoscimento del ruolo sociale ed urbano dello spazio pubblico, elemento ristrutturante il tessuto urbano ed umano. La progettazione di nuovi spazi collettivi nei contesti urbani più fragili, più marginali ed abbandonati della città, può dar inizio ad un rinnovamento urbano e sociale, offrire scenari di vita sostenibile e garantire il diritto alla città

Unverzeihlicher Antikonformismus: Die Schriften Hans Paasches in der Ära des deutschen Kolonialismus

In an entry of his 1916 journal, Hans Paasche (1881-1920) wrote a long reflection on metánoia, a concept indicating a radical shift in thinking. In fact, the whole life of Hans Paasche itself could be read as such a radical conversion. He was all that follows: officer in the repression of the Maji-Maji riots in the German colonies of Ostafrika, skilled hunter, volunteer in the Great War, and then vigorous pacifist, relentless opponent of alcohol abuse and fervent vegetarian, ironic writer and passionate political reformer. In a context in which attempts at change were seen as traitorous, his life shows that self-acknowledgement may lead to marginalisation and to murder. The absence of forgiveness and understanding in his case still continues and his work and thought have been almost totally removed from any public and literary discourse in Germany. This paper intends to analyze his thought through his works, mainly "Die Forschungsreise des Afrikaners Lukanga Mukara ins innerste Deutschland", highlighting how, in his later years, Paasche felt the need to communicate his traumatic experiences with the intent of avoiding their repetition

Diseño del colector y ocurrencia de deslizamiento de pezoneras durante el ordeñe de vacas y vaquillonas : (Estudio de caso)

El objetivo de este trabajo fue comparar el número de deslizamientos de pezoneras ocurridos durante el ordeñe con colectores de diferente diseño. La diferencia entre colectores consistió en la posición de los nipples que conectan la tapa del colector con las pezoneras de los cuartos traseros de la ubre. Se utilizó un colector con nipples paralelos (P) y otro con nipples no paralelos (Np) en cada ordeñe, realizando un ordeñe con cada diseño de colector. El diseño P mejoraría el posicionamiento de las pezoneras durante el ordeñe y reduciría la ocurrencia deslizamiento en comparación con el diseño Np. Este trabajo se desarrollo en un tambo comercial en donde se evalúo el número de deslizamientos ocurridos en dos ordeñes consecutivos realizados con uno u otro diseño de colector. Se ordeñaron 411 animales divididos en dos grupos cada vez (215 vacas y 196 vaquillonas), durante cada ordeñe se observo y registró la ocurrencia de deslizamiento de pezoneras en cada animal de cada grupo. El numero de animales con deslizamientos de pezoneras fue mayor cuando se utilizó el colector Np que con P, y menor en vacas que en vaquillonas
