TEORIE DEL CICLO ECONOMICO. Il dibattito macroeconomico moderno su instabilità e equilibrio
No full textTrade unions, differential games and economic cycles
No full textIn this paper an integration is developed between the dynamic models formulated by the microeconomic theory of trade unions and the differential games approach. The resulting Nash differential game between firms and unionised workers describes the process of distributive conflict in a simplified capitalist economy. Moreover, the solutions of this dynamic game imply a cycle in the wage share of product and the employment rate. We then determine the Pareto efficient solution, and we show that the these trajectories are cyclical for the same parameter values of the Nash game; nonetheless these cycles are different from those derived from the noncooperative solution. These results are obtained by use of the Hopf theorem on local bifurcations
La teoria economica del sindacato e la prospettiva europea
No full textIn questo articolo viene fornita una presentazione critica dei principali contributi offerti dalla recente analisi economica al dibattito sul ruolo economico del sindacato nel contesto dell’unificazione monetaria europea. Viene presentata una sintetica rassegna dei principali risultati raggiunti dalla teoria economica in merito all’analisi del comportamento delle organizzazioni sindacali e della contrattazione salariale. Questi modelli economici di sindacato sono stati impiegati estesamente nell’economia
del lavoro, nelle recenti analisi macroeconomiche e nelle analisi di politica economica. Relativamente al rapporto tra sindacati ed unione monetaria europea, la teoria economica recente mette in luce due questioni. In primo luogo, la necessità per le autorità di politica economica nazionali di individuare nuovi strumenti di politica per l’occupazione, come la gestione o regolazione degli orari di lavoro. In secondo luogo emerge la questione della struttura della contrattazione a livello europeo, articolata in tre temi specifici: livelli multipli di contrattazione, struttura per gruppi della contrattazione e decentramento o centralizzazione della contrattazione stessa
Cooperative and noncooperative differential games between firms and trade unions
No full textIn this paper we integrate the dynamic models formulated by the microeconomic theory of trade unions and the differential games approach. We demonstrate that the results of the dynamic monopoly union model, elaborated by Kidd and Oswald (1987) and Jones and McKenna (1994), can be obtained as solutions of a Stackelberg differential game between a firm and a union under particular assumptions on union’s membership dynamic. We then turn our attention to the cooperative bargaining case, and we show how the optimal threat strategies can be determined, allowing to calculate the threat point payoffs
I siti web della salute: aspetti normativi e criteri di qualità.
No full textL'articolo prende in considerazione i criteri di qualità per i siti web proposti dal W3C e dalla Commissione delle Comunità Europee per i siti contenenti informazioni di carattere medico. Inoltre si propone un excursus sulla normativa italiana di riferimento., augurandosi che si vada verso un accordo condiviso e formalizzato sui criteri di valutazione dei siti relativi ai temi di salute

Reti sociotecniche e vita quotidiana Uno studio sul malfunzionamento tecnologicoe le dinamiche sociali nell'ospedale Sant'Anna di Ferrara
No full textIn this work I will deal with the subject of the society-technology relation by investigating some phenomena associated with a series of information systems' failures that affected an important italian hospital. I will assume (this is my starting hypothesis) that an unexpected system crash is associated with some specific social dynamics so that the failure itself can be seen as a “revealer phenomenon” that is able to show a set of shared practices, representations and rhetorics about the role of technology in everyday life.
In order to verify this theory, I paid attention to the case of some serious system failures that happened at Sant'Anna Hospital of Ferrara (Italy) in 2008. By using an ethnographic research approach I interviewed 15 employees of the hospital. In order to have a good set of point of views, I chose some employees belonging to the organizational-administrative side and some others to the health one.
The main results can be placed on three main levels.
From a micro point of view I pointed out that the system crash was associated with some relevant phenomena concerning the individual and the relational sphere of the employees, even if with important a between the administrative employees and the health ones. Everyone asserted the absolute necessity of computers and information system, however while administrative employees assumed the importance of such technology simply as an exploitable mean, on the other side the health workers considered the same technology and the computerized objects as something more, that is as entities contributing to the construction of their own professional identity and activity. As a result, the system failure generates a greater sense of anxiety and a notable increase of social interactions as the result of the sudden creation of two new patients looking for some treatment: the health worker, assumed as an hybrid entity temporarily crippled, and the computer or the information system itself, that does not work or does not work properly.
From a mesoscopic point of view, the workers constantly attempted to locate the cause of the computer crash in the process of innovation that regards the implementation of the computerized infrastructure that occurred in the last 7 years. As the outcome of that innovation process is described as the result of disputes, conflicts and negotiations between many actors, there is a common propensity to underline an association of the computer system failure with an organizational failure.
Finally, from a macro point of view, the whole accounts showed to be directed towards a common perspective that assumes computer systems as a characteristic element of modernity, whose management is a prerogative of hi-tech personnel
Modelli dinamici del sindacato: estensioni e critiche
No full textIn this paper we will describe the basic features of the standard dynamic model of monopoly union
in a critical perspective; starting by the Kidd - Oswald - Jones - McKenna dynamic models, we will suggest
some extensions and developments, aimed to underline the importance of the strategic aspects ignored
by the standard literature. By means of the theorems and concepts peculiar to the differential game
theory, we will show the different solutions, in terms of wages and employment, due to the explicit analysis
of the strategic-dynamic interaction between union and firms, together with the biases due to the use
of the static models

No full textL'articolo presenta i risultati di una ricerca condotta su 200 siti internet italiani relativi ai temi del benessere e della sanità. Partendo da venti parole chiave, di cui dieci appartenenti all'area "medicina-sanità" e dieci all'area benessere, si è selezionato un campione di spazi web emersi dal motore di ricerca Google. Si tenta di dare, pertanto, una descrizione del panorama italiano dei siti sanitari e benessere, facendo emergere alcuni nodi problematici che verranno affrontati in ulteriori approfondimenti
