“…Over the past decade, the Hawkes model has become very popular in financial applications, mostly for modeling highfrequency fluctuations of prices and limit order book dynamics (Bowsher, 2007;Bauwens and Hautsch, 2009;Toke, 2011;Cont, 2011;Aït-Sahalia et al, 2011;Filimonov and Sornette, 2012;Bacry et al, 2012;Chavez-Demoulin and McGill, 2012;Hardiman et al, 2013), and for the modeling of sequences of lower-frequency extreme events (Chavez-Demoulin et al, 2005;Errais et al, 2010;Embrechts et al, 2011). In this section, we present a data-driven motivating example for applications of the RHawkes model within the context of quantitative finance.…”
