Tourism multipliers allow researchers to analyze the effect or consequences caused in tourism development of an area or country by a unit of added tourism expenditure. The development and implementation of tourism multiplier models is proportional to the progress of the aggregate economic theory which in many cases has defined the sense and contents of tourism development. Researchers and investigators of tourism activity have been dealing with the issue of the capacities and constraints of these tourism multipliers for the evaluation of the developmental impact of tourism. The analysis of the topic in question generates various conclusions on the suitability of the major tourism multiplier models, the limits of their capacities and their constraints and also the comparability of the values of the various categories of multipliers arising from different models and concerning economically heterogeneous tourism locations/countries.
