“…Tourism demand studies generally assume that the effects of income and price on demand for tourism remain stable across the business cycle (Crouch, 1995;Lim, 1997;Li et al, 2005;Song and Li, 2008;Song et al, 2010;Schiff and Becken, 2011). In contrast to these studies, the modified growth rate (MGR) model and the time-varying parameter (TVP) model dilute the assumption of parameter constancy (Harvey, 1990;Song et al 2009;Smeral, 2009Smeral, , 2010Smeral, , 2011Smeral, , 2012. Moreover, applying the recursive ordinary least square (OLS) method shows that the assumption of constant parameters is too restrictive (Song and Witt, 2000).…”
