Non-Price Competition and Exchange Rate Pass-Through

A substantial body of empirical works document that exchange rate pass-through to consumer prices is incomplete. This evidence has cast doubts on the ability of flexible exchange rates to generate expenditure switching. In a dynamic stochastic discrete-time duopoly game, non-price competition among .rms endogenously originates a degree of exchange ratepass-through close to zero together with an expenditure switching e¤ect stronger than in the standard models.pass-through, non-price competition, expenditure switching

Racconti di guerra dall’Unione Sovietica. La ricezione dell’opera di Alja Rachmanova nell’Italia fascista

Il contributo è incentrato sull'analisi delle ragioni per cui in Italia nel corso degli anni '30 del Novecento si è assistito al proliferare di edizioni italiane delle opere della scrittrice russa dell'emigrazione Alja Rachmanova, testimone dei sanguinosi fatti che accompagnarono l'ascesa del potere bolscevico in Unione Sovietica

Probabilistic approach to non-local equations

The work focuses on probabilistic representation of solutions of non-local equations, where the considered non-local operators are either Caputo-type derivatives or trasformations of the Laplace operator via Bernstein functions. The first chapter is devoted to the introduction of the main tools, that is to say Bernstein functions, subordinators and their inverse processes, Caputo-type derivatives and Bochner subordination. In the second chapter we focus on theoretical results concerning probabilistic representation of non-local equations involving Caputo-type derivatives. First we study a general theory for abstract Cauchy problems involving such kind of derivatives, focusing also on the eigenfunctions of such Caputo-type derivatives and Gronwall-type inequalities. Then we exploit the link between time-changed birth-death processes and abstract Cauchy problems in suitable Banach sequence spaces, via a spectral decomposition approach. Then we consider how the Fokker-Planck equation of a non-Markov Gaussian process changes after applying a time-change via the inverse of a subordinator. Finally, we consider exit times of time-changed processes, their asymptotic problems and the link between their survival probability and solutions of non-local (in time) parabolic PDEs. The third chapter is devoted to applications of the previously presented theoretical results. In particular we focus on queueing theory and computational neuroscience. Moreover, we also exploit some simulation properties to work with such processes. In the fourth and last chapter we focus on non-local operators in space with two exemplary problems. The first one concerns the integral representation of Bernstein functions of the Laplace operator. In particular we prove asymptotic properties of the singular kernel of such integral representations depending on asymptotic properties of the Levy measure of the considered Bernstein function. The second problem deals with spectral properties of a Marchaud-type operator on the sphere. In particular, we prove an identity involving the first eigenvalue of the aforementioned operator and moments of the length of random segments in the unit ball

A preliminary numerical and experimental investigation on the shear stress distribution on multi-row bolted FRP joints

The first results of a numerical and experimental investigation on the shear forces distribution in a bolted joint made entirely from FRP materials are presented. It is also proposed an experimental equipment for investigating the strains and stresses distributions around the holes of the connection as well as the bearing stresses at the interface between plate and steel bolt. A good agreement between numerical and experimental results allows to use the proposed testing set-up for analysing the bearing failure of several joint configuration with different lamination scheme, geometry and type of load

Motor activities and paddle during COVID-19

The purpose of this research work is to highlight the contribution that a motor and sports practice such as Paddle can provide during a particular period like the current one, marked by the presence of the COVID-19 virus which negatively affects the development of social, relational, and educational aspects of any person practicing this sport. This paper aims to highlight the educational importance of the movement through the sports discipline of Paddle, especially in a negative period like the one we are going through, due to the health and social pandemic of "Corona Virus"
