“…Others, such as Perez and Sampol (2000), Wang et al (2006), Apostolakis and Jaffry (2009), Marrocu et al (2015), and Serra et al (2015) use daily personal expenditure, thereby acknowledging that daily spending and length of stay are two different decisions, albeit interrelated. This, in turn, gives rise to the analysis of length of stay independently, such as the works of De Menezes et al (2008), Barros and Machado (2010), Thrane and Farstad (2012b), Montaño et al (2019), Vieira et al (2021), and Atsız et al (2022). Whether modeling daily spending or length of stay, literature repeatedly reports measures of tourists’ socioeconomic characteristics, trip-specific choices, and psychological attributes as valid exogenous determinants of both decisions, thereby lending collective support to reduced-form modeling of both decisions as one construct in the form of total expenditure, without disentangling potential asymmetries in the two processes.…”
