An analysis on travel party composition and expenditure: a discrete-continuous model

While the interrelated nature of tourism decisions is well recognised, there is a significant gap between conceptual understanding and modelling practice. Empirically, the interrelations between tourism decisions are often not tested and quantified because the research technique does not embody the capacity to test for the correlations between these decisions. This research aims to empirically investigate these interrelationships by using a multinomial discrete-continuous model estimated with trip expenditure hazard-based function. In the context of domestic tourism in Australia, this study adds to the emerging body of research by finding quantifiable evidence that travel party choices, travel mode choices, and expenditure decisions are interrelated, contributing towards developing a more nuanced understanding of these decisions.
