The economic cost of social distancing during a pandemic: an optimal control approach in the SVIR model
Springer Science and Business Media LLC -
Alessandro Ramponi, Maria Elisabetta Tessitore
AbstractWe devise a theoretical model for the optimal dynamical control of an infectious disease whose diffusion is described by the SVIR compartmental model. The control is realized through implementing social rules to reduce the disease’s spread, which often implies substantial economic and social costs. We model this trade-off by introducing a functional depending on three terms: a social cost ... hiện toàn bộ

Time-consistency of risk measures: how strong is such a property?
Springer Science and Business Media LLC - Tập 42 - Trang 287-317 - 2019
Elisa Mastrogiacomo, Emanuela Rosazza Gianin
Quite recently, a great interest has been devoted to time-consistency of risk measures in its different formulations (see Delbaen in Memoriam Paul-André Meyer, Lecture notes in mathematics, vol 1874, pp 215–258, 2006; Föllmer and Penner in Stat Decis 14(1):1–15, 2006; Bion-Nadal in Stoch Process Appl 119:633–654, 2009; Delbaen et al. in Finance Stoch 14(3):449–472, 2010; Laeven and Stadje in Math ... hiện toàn bộ
Su alcunieffetti dell'adozione di iniziali finitamente additive quando il modello di base appartiene alla classe esponenziale troncata
Springer Science and Business Media LLC - Tập 11 - Trang 147-161 - 1988
Cinzia Carota, Francesco Corielli
In questo lavoro si adottano particolari iniziali finitamente additive volte a massimizzare l'associazione tra gli elementi di un processo scambiabile e vengono discussi effetti e significato complessivo di tale adozione (par. 1 e 2). Nell'ipotesi che tali distribuzioni si riferiscano al parametro di un modello appartenente alla classe esponenziale troncata si ottiene (par. 3) la corrispondente es... hiện toàn bộ
Non-compliant behaviour in public procurement: an evolutionary model with endogenous monitoring
Springer Science and Business Media LLC - Tập 44 Số 1 - Trang 459-483 - 2021
Raffaella Coppier, Francesca Grassetti, Elisabetta Michetti
AbstractIn recent years, the study of the evolution of non-compliant behaviour in public procurement has been widely developed due to the growing economic relevance of this phenomenon. When such a question is formalized in terms of a dynamical model, new insights can be pursued, related to the possible evolution from a situation with low dishonesty level to high dishonesty level or vice versa. The... hiện toàn bộ
On the computability of quasi-transitive binary social choice rules in an infinite society and the halting problem
Springer Science and Business Media LLC - Tập 32 - Trang 67-78 - 2009
Yasuhito Tanaka
This paper investigates the computability problem of the existence of a vetoer and an oligarchy for quasi-transitive binary social choice rules (Mas-Colell and Sonnenschein in Rev Econ Stud 39:185–192, 1972) in a society with an infinite number of individuals (infinite society) according to the computable calculus (or computable analysis) by Aberth (Computable analysis, McGraw-Hill, New York, 1980... hiện toàn bộ

Un algoritmo misto per il problema dell'assegnazione pluridimensionale
Springer Science and Business Media LLC - Tập 6 - Trang 67-78 - 1983
Paola Olivo
In questa nota si studia il problema di assegnazione 3-dimensionale con una estensionek-dimensionale, e si propone un algoritmo risolutivo misto derivato dall'algoritmo Ungherese e dalle tecniche «branch and bound».
On the aubin-like characterization of competitive equilibria in infinite dimensional economies
Springer Science and Business Media LLC - Tập 19 - Trang 187-203 - 1996
Achille Basile, Anna De Simone, Maria Gabriella Graziano
For an exchange economy with finitely many agents and a commodity space which is infinite dimensional, it is proved that competitive equilibria are the same as allocations belonging to the fuzzy core of the economy. The latter is further characterized as a subset of the ordinary core of a suitably associated continuum economy.
Grey Verhulst model and its chaotic behaviour with application to Bitcoin adoption
Springer Science and Business Media LLC - Tập 45 - Trang 327-341 - 2022
P. Gatabazi, J. C. Mba, E. Pindza
The study applies the grey model (GM(1,1)) to the Verhulst differential equation for forecasting the Bitcoin transaction counts. The grey Verhulst model (GVM) is based on the data set of Bitcoin as recorded along 10 years from the 1st August 2010. The model accuracy is checked by the mean absolute percentage error (MAPE), while the model predictability is assessed by analysing a plot of the Verhul... hiện toàn bộ
