The optimal diffusion of a new technology when both demand and supply are nonstatic
No full textThe investment problem of a monopolized sector selling an innovated product is explored. Learning by doing is supposed to occur on the supply side, while learning by using is introduced to explain demand growth. Pontryagin's maximum principle is applied to the resulting optimal control problem, which includes supply capacity and cumulative output as state variables. The optimal investment policy turns out to be of a very simple form: all profit is retained and invested until capacity achieves its optimal size. In spite of this, the new technology price displays a variety of time patterns that heavily depend on the actual demand and cost conditions, as one would expect in the real world
Taxing overexploited open-access fisheries: the role of demand elasticity
No full textThe paper aims at identifying the effects exerted by a tax levy on an overexploited and previously unregulated fishery. The analysis is carried out by means of a dynamic model that includes fish stock and harvesting effort as state variables. Attention is focused on the role played by demand elasticity which is shown to affect both transients and equilibria. According to the analysis, a levy induces a contraction in effort, which is sharper in the short term. As a consequence, the fish population recovers and ultimately settles at a higher equilibrium level. Therefore, a larger amount of fish is caught in the long run and sold at a lower price than in the unregulated setting. The more inelastic the demand, the smaller both the equilibrium price for fish and the tax imposed

Valutazione della sostenibilità economica e finanziaria del sistema di servizi assistenziali agli anziani non autosufficienti: il caso della provincia autonoma di Trento
No full textLa Provincia Autonoma di Trento ha da tempo avviato il processo di riordino delle
Aziende Pubbliche di Servizi alla Persona (A.P.S.P.), con l’introduzione di due
fondamentali elementi di novità: la possibilità, da parte delle strutture, di estendere i
servizi erogati; l’adozione di un modello di aziendalizzazione.
I cambiamenti hanno determinato una forte responsabilizzazione sul conseguimento
del pareggio economico in bilancio, obbligando le A.P.S.P. ad un attento governo
dell’equilibrio ricavi-costi.
Il presente lavoro mira a fornire una prima valutazione della sostenibilità economica e
finanziaria del sistema di servizi assistenziali trentini, con l’obiettivo principale di
individuare i driver di redditività, sia esaminando il ruolo e la rilevanza dei nuovi
servizi erogabili in termini di ricavi aggiuntivi, sia approfondendo le caratteristiche
delle diverse strutture di costo e le correlate modalità di gestione degli stessi.
Lo studio prende a riferimento un campione selezionato di nove aziende di dimensioni
comprese tra 45 e 90 posti letto. Attraverso l’analisi dei dati di bilancio relativi al
biennio 2008-2009, vengono evidenziati alcuni fattori potenzialmente critici per il
governo dei servizi socio-sanitari sul territorio trentin

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“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
