No full textVariations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Optimal investment with vintage capital: Equilibrium distributions
No full textThe paper concerns the study of equilibrium points, or steady states, of economic systems arising in modeling optimal investment with vintage capital, namely, systems where all key variables (capitals, investments, prices) are indexed not only by time but also by age. Capital accumulation is hence described as a partial differential equation (briefly, PDE), and equilibrium points are in fact equilibrium distributions in the variable of ages. A general method is developed to compute and study equilibrium points of a wide range of infinite dimensional, infinite horizon, optimal control problems. We apply the method to optimal investment with vintage capital, for a variety of data, deriving existence and uniqueness of equilibrium distribution, as well as analytic formulas for optimal controls and trajectories in the long run. The examples suggest that the same method can be applied to other economic problems displaying heterogeneity. This shows how effective the theoretical machinery of optimal control in infinite dimension is in computing explicitly equilibrium distributions. To this extent, the results of this work constitute a first crucial step towards a thorough understanding of the behavior of optimal paths in the long run

Reglering med int\ue4ktstak - incitament p\ue5 kort och l\ue5ng sikt
No full textI denna rapport konstateras att int\ue4ktstak \ue4r en regleringsmodell som dras med tv\ue5 mycket allvarliga l\ue5ngsiktiga problem. F\uf6r det f\uf6rsta m\ue5ste regleraren best\ue4mma parametrarna i modellen med omsorg, s\ue5 att den inte ger felaktiga styrsignaler. Eftersom de styrsignaler modellen ger baseras p\ue5 int\ue4ktstakets lutning i f\uf6rh\ue5llande till monopolets kostnadsfunktioner p\ue5 kort och l\ue5ng sikt kan det vara sv\ue5rt eller om\uf6jligt att fastst\ue4lla modellparametrar som styr "r\ue4tt" p\ue5 b\ue5de kort och l\ue5ng sikt, d\ue5 dessa kostnadsfunktioner normalt sett \ue4r olika. F\uf6r det andra kr\ue4vs att regleraren har tillg\ue5ng till detaljerad information om monopolets kostnadsvillkor p\ue5 b\ue5de kort och l\ue5ng sikt f\uf6r att kunna avg\uf6ra hur olika v\ue4rden p\ue5 int\ue4ktstakets parametrar p\ue5verkar monopolets beteende
