An extension of the research would be to include in one empirical study companies playing a dual role as both visitors and exhibitors at TSs. This would give a different and very promising perspective. This empirical setting would allow for an accurate analysis of the differences between exhibitors and visitors in the TSE model.
It would also be very interesting to consider an empirical setting in which to explore the dynamic aspects of TS participation. By collecting information from a panel of visitors, it would be possible to analyze the effects of past experience on the assessment of TSs.
