The purpose of the paper is to provide an econometric classification and evaluation of 100 published empirical studies on modelling international tourism demand, according to the recognition and type of omitted explanatory variables, number and type of proxy variables used, method of estimation, and use of various diagnostic tests of the auxiliary assumptions of the various models. An analysis of the adequacy of model specifications and the statistical deficiencies of existing empirical tourism demand models will permit a greater appreciation of the factors which determine changes in international tourism demand and will aid in forecasting future tourism demand.
