We measure the impact using Italian electoral data from 2018 and 2022 general elections at the municipal level through a shift-share approach, attributing the sector-level export shock to each municipality according to its employment composition. Our results show that votes to the League (the most pro-Russian party in Italy) increase by 3.8 percentage points for every 1,000 Euro of Russian per-capita export shock at the municipal level. Votes to other parties and turnout do not appear to be affected.

These include randomized feed-forward neural networks, randomized recurrent neural networks, and a novel method based on signatures of the underlying price process. Additionally, we explore potential applications on callable certificates. Furthermore, we present an innovative approach for calculating sensitivities, specifically Delta and Gamma, leveraging Chebyshev interpolation techniques.

Filippi-Mazzola) https://www.dse.univr.it/?ent=seminario&rss=0&lang=en&id=6353 Relatore: Raffaele Argiento; Provenienza: Università di Bergamo; Data inizio: 2024-10-24; Ora inizio: 12.00; Referente interno: Catia Scricciolo; Riassunto: This talk describes a new model-based approach for clustering categorical data with no natural ordering. The proposed method exploits the Hamming distance to define a family of probability mass functions to model the data. The elements of this family are then considered as kernels of a finite mixture model with an unknown number of components. Conjugate Bayesian inference is derived for the parameters of the Hamming distribution model. The mixture is framed in a Bayesian nonparametric setting, and a transdimensional blocked Gibbs sampler is developed to provide full Bayesian inference on the number of clusters, their structure and the group-specific parameters, facilitating the computation with respect to customary reversible jump algorithms. The proposed model encompasses a parsimonious latent class model as a special case when the number of components is fixed. Model performances are assessed via a simulation study and reference datasets, showing improvements in clustering recovery over existing approaches.

Decision making under ignorance compares finite sets of final consequences while decision making under objective ambiguity compares finite sets of probability distributions over those final consequences. The criteria characterized assign to every element in a set a weight that depends upon the rank of this element if it was available for sure (non-ambiguously) and that compare sets on the basis of their weighted utility for some utility function. We also discuss the implication of comparative attitudes to ignorance or ambiguity on the form of the weights and the utility functions and provide an additional characterization of a subfamily of these criteria that requires the rank-dependent weights to result from a probability weighting function.
