Dinamiche della disuguaglianza e della robotizzazione: Un'analisi longitudinale
2022
Il crescente trend di automazione dei processi produttivi sta alimentando non poche preoccupazioni circa la possibilità che, in un futuro non troppo remoto, una quota rilevante di lavori tradizionali sarà rimpiazzata tout-court dai robot o dall’intelligenza artificiale, esacerbando, conseguentemente, le disuguaglianze. Con particolare riferimento all’impatto dei robot su svariati indicatori del mercato del lavoro, la letteratura empirica, attualmente, si è rivelata infruttuosa nel fornire risposte definitive ed esaustive, producendo evidenze contrastanti. Il presente contributo si inserisce nel dibattito in corso, proponendo un’indagine sulle dinamiche della robotizzazione e delle disparità…
Stochastic differential calculus for wind-exposed structures with autoregressive continuous (ARC) filters
2008
In this paper, an alternative method to represent Gaussian stationary processes describing wind velocity fluctuations is introduced. The technique may be considered the extension to a time continuous description of the well-known discrete-time autoregressive model to generate Gaussian processes. Digital simulation of Gaussian random processes with assigned auto-correlation function is provided by means of a stochastic differential equation with time delayed terms forced by Gaussian white noise. Solution of the differential equation is a specific sample of the target Gaussian wind process, and in this paper it describes a digitally obtained record of the wind turbolence. The representation o…
Quadratic backward stochastic differential equations
2017
Tässä tutkielmassa analysoimme takaperoisia stokastisia differentiaaliyhtälöitä. Aloitamme esittelemällä stokastiset prosessit, Brownin liikkeen, stokastiset integraalit ja Itôn kaavan. Tämän jälkeen siirrymme tarkastelemaan stokastisia differentiaaliyhtälöitä ja lopulta takaperoisia stokastisia differentiaaliyhtälöitä. Tämän tutkielman pääaiheena on takaperoiset stokastiset differentiaaliyhtälöt kvadraattisilla oletuksilla. Näillä oletuksilla todistamme olemassaoloteoreeman ja tietyt säännöllisyysehdot takaperoisen stokastisen differentiaaliyhtälön ratkaisulle. In this thesis, we analyze backward stochastic differential equations. We begin by introducing stochastic processes, Brownian moti…
Operator splitting methods for American option pricing
2004
Abstract We propose operator splitting methods for solving the linear complementarity problems arising from the pricing of American options. The space discretization of the underlying Black-Scholes Scholes equation is done using a central finite-difference scheme. The time discretization as well as the operator splittings are based on the Crank-Nicolson method and the two-step backward differentiation formula. Numerical experiments show that the operator splitting methodology is much more efficient than the projected SOR, while the accuracy of both methods are similar.
