“…Consequently, a large number of studies in tourism have investigated the determinants of tourism expenditure (e.g., Cai, 1999;Cai, Hong and Morrison, 1995;Dardis, Derrick, Lehfeld and Wolfe, 1981;Dardis, Soberon-Ferrer and Patro, 1994;Davies and Mangan, 1992;Fish and Waggle, 1996;Hsieh, Lang and O'Leary, 1997;Nicolau and Mas, 2005). A related stream of research has investigated patterns in tourist expenditures and how these expenditures might differ between a priori defined segments of tourists (for instance, Hong, Kim and Lee, 1999;Jang, Bai, Hong and O'Leary, 2004;Opperman, 1996).…”
