L'uso della metafora bellica nella definizione del fenomeno pandemico
No full textThe cataclysm triggered by the emergence of Covid-19 led from a justified (and healthy) fear of contagion to a form of moral panic and consequently to the demand for greater security. The current state of emergency has tested and will continue to test the institutions and their ability to find and implement solutions that minimize the damage suffered without restricting individual freedoms. Those who felt entrusted with the institutional and political responsibility of explaining to the masses once again focused on the same event as it had “inevitably” not happened for almost twenty years, using the most basic rhetorical figures, which at the same time were more effective in terms of communication. Since the beginning of the epidemic, first in China, then in Italy and Europe and finally throughout the world, politicians, journalists, doctors, economists and opinion leaders have defined the health emergency as “war”. From the beginning, the metaphor of war was used and abused, and the first and most vocal spread of the concept of war and related terms were politicians
Democratizzazione e demercificazione del lavoro al servizio della riconversione ecologica post Covid-19
No full textIl Covid-19 ha stravolto la vita quotidiana dell’intera popolazione mondiale producendo un mutamento sociale epocale. Durante le prime settimane di febbraio 2020, quando gli italiani stavano prendendo coscienza di quello che stava accadendo, ci siamo interrogati spesso sul ruolo che le scienze sociali e, in particolare, la sociologia avrebbero dovuto svolgere durante l’emergenza sanitaria e la sua narrazione pubblica.
Il bisogno di reagire alla difficile situazione ci ha portati ad offrire al dibattito pubblico il nostro contributo di studiosi e ricercatori di scienze sociali. Questa spinta, con il passare del tempo, si è tradotta nella costruzione e organizzazione di un nuovo progetto scientifico ed editoriale che integrasse l’approccio tipico dell’inchiesta e dell’analisi sociale con lo strumento dell’intervista radiofonica. Così è nata, dunque, Radio Covid, un contenitore digitale all’interno del quale si sono alternati illustri esponenti della sociologia italiana.
Questo libro vuole raccogliere quella condivisione di sapere sociologico che si è dialetticamente costruito durante l’emergenza pandemica, con l’obiettivo di dare il giusto valore al contributo che la teoria sociale e la ricerca empirica hanno proposto al dibattito pubblico e alla riflessione generale intorno al Covid-19.
Gli ospiti delle puntate di Radio Covid hanno affrontato moltissimi temi di rilievo presenti nell’agenda sociopolitica che ha imposto il Coronavirus: dall’impatto ambientale al problema della sicurezza e delle regole del gioco democratico; dal ruolo giocato dall’Unione Europea e dall’Organizzazione Mondiale della Sanità alle politiche di welfare sanitario e alle problematiche relative al Sistema Sanitario Nazionale; dalle questioni relative alla comunicazione istituzionale e massmediatica alle ripercussioni sul mercato del lavoro e sui flussi di migranti; dagli stravolgimenti causati nel mondo dello sport a quelli registrati nella sfera religiosa; dalla crisi del sistema scolastico alle nuove forme di didattica a distanza.
Un testo agile che vuole dare l’opportunità agli addetti ai lavori e a un pubblico più vasto interessato alle dinamiche sociali, di orientarsi nel più grande cambiamento della nostra vita quotidiana sopraggiunto dopo la tragedia della Seconda Guerra Mondiale.Covid-19 has disrupted the daily lives of the entire world's population and brought about epochal social change. Consequently, during the last month of February, as Italians became aware of what was happening, we often wondered what role Social Sciences, and sociology in particular, had to play in the health emergency and its public presentation. The need to respond to the difficult situation and to contribute to the public debate therefore led us to launch a new editorial project integrating social research and the radio interview approach, in order to start interpreting the Covid-19 phenomenon from a sociological perspective. Thus, Radio Covid was born and we started our interviews with well-known guests from the Italian civil society and sociological community. Building on the experience of Radio Covid, this book presents the efforts of sociological intervention during a pandemic emergency and shows the contribution that Public Sociology can make not only to the Covid-19 debate but also to the good practices applied in an emergency. Guests on the talk shows of Radio Covid have become authors addressing many important issues on the socio-political agenda imposed by the coronavirus. Many topics have been analyzed on the radio shows: the impact of Covid-19 on the environment, the security problem and the democratic rules of the game, the role of European Union and the World Health Organization, health policy and the problems associated with National Health System, institutional and mass media communication issues, the impact on the labor market, upheavals in the world of sports, and concerns in the area of religiosity. In sum, the reader can use this volume as a nimble guide to help both professionals and a broader audience interested in social dynamics navigate the greatest change in our daily lives since the tragedy of World War II

Taming the Spread of an Epidemic by Lockdown Policies
Full text linkFederico S, Ferrari G. Taming the Spread of an Epidemic by Lockdown Policies. Center for Mathematical Economics Working Papers. Vol 639. Bielefeld: Center for Mathematical Economics; 2020.We study the problem of a policymaker who aims at taming the spread of an epidemic
while minimizing its associated social costs. The main feature of our model lies in the fact that the
disease's transmission rate is a diffusive stochastic process whose trend can be adjusted via costly
confinement policies. We provide a complete theoretical analysis, as well as numerical experiments
illustrating the structure of the optimal lockdown policy. In all our experiments the latter is characterized
by three distinct periods: the epidemic is first let freely evolve, then vigorously tamed, and
finally a less stringent containment should be adopted. Moreover, the optimal containment policy is
such that the product "reproduction number x percentage of susceptible" is kept after a certain date
strictly below the critical level of one, although the reproduction number is let oscillate above one in
the last more relaxed phase of lockdown.MSC2010 subject classification: 93E20, 49N90, 92D30, 97M4
Singular Control of the Drift of a Brownian System
Full text linkFederico S, Ferrari G, Schuhmann P. Singular Control of the Drift of a Brownian System. Center for Mathematical Economics Working Papers. Vol 637. Bielefeld: Center for Mathematical Economics; 2020.We consider a standard Brownian motion whose drift can be increased or decreased in a possibly singular manner. The objective is to minimize an expected functional involving the time-integral of a running cost and the proportional costs of adjusting the drift. The resulting two-dimensional degenerate singular stochastic control problem is solved by combining techniques of viscosity theory and free boundary problems. We provide a detailed description of the problem's value function and of the geometry of the state space, which is split into three regions by two monotone curves. Our main result shows that those curves are continuously di fferentiable with locally Lipschitz derivative and solve a system of nonlinear ordinary diff erential equations.MSC2010 subject classification: 93E20, 91A55, 49L25, 49J40, 35R35, 91B6

On the singular control of exchange rates
Full text linkFerrari G, Vargiolu T. On the singular control of exchange rates. Annals of Operations Research. 2020;292:795-832.Consider a central bank that wants to manage the exchange rate between its domestic currency and a foreign one. The central bank can purchase and sell the foreign currency, and each direct intervention on the exchange market leads to a proportional cost whose instantaneous marginal value depends on the current level of the exchange rate. The central bank aims at minimizing the total expected costs of interventions on the exchange market, plus a total expected running cost. We formulate this problem as an infinite time-horizon bounded-variation stochastic control problem. The exchange rate evolves as a general one-dimensional diffusion, and it is linearly controlled by two nondecreasing processes modeling the cumulative amount of foreign currency that has been purchased and sold by the central bank. We provide a complete solution to this problem by finding the explicit expression of the value function and a complete characterization of the optimal control. At each instant of time, the optimally controlled exchange rate is kept within a band whose size is endogenously determined as part of the solution to the problem. We also study the expected exit time from the band, and the sensitivity of the width of the band with respect to the model's parameters in the case when the exchange rate evolves (in absence of any intervention) as an Ornstein-Uhlenbeck process, and the marginal proportional costs of controls are constant. The techniques employed in the paper are those of the theory of singular stochastic control and of one-dimensional diffusions
