Se vi interessa inviare un articolo potete scrivere a Lorenzo Torricelli e/o a me. Grazie per l'attenzione e cordiali saluti, Enrico Scalas -- Call for Papers Special Issue on Non-Markovian dynamics in finance: factor modelling and beyond Guest Editors: Enrico Scalas (Department of Statistical Sciences, Sapienza University of Rome) Lorenzo Torricelli (Department of Statistical Sciences, University of Bologna) Scope and Objectives Factor models are an established framework in financial modeling, essential for capturing the inherent complexity of market dynamics. Recent research has increasingly moved toward relaxing the Markov property of underlying stochastic drivers, primarily for two reasons: to achieve a more robust fit for the statistical properties of volatility, and to account for the empirical reality of periods of price staleness and non-exponential inter-trade durations. This special issue serves as a forum for these two methodological strands to converge, highlighting their synergies or, more ambitiously, discussing unified frameworks for their joint implementation. Topics of Interest Contributions on option pricing, portfolio selection, market microstructure and other relevant problems in quantitative finance are welcome. Theoretical contributions are also welcome, provided they have demonstrable applicability in finance.
