association with demand for trips, although its coefficient is significant only at the 10%.
Most important, the demand for trips is greater among persons who regard the cultural
heritage site to be in good shape. Persons who hold this opinion visit about 52% more
often—on average, 1.5 times a year more—than the others.

7. Discussion and Conclusions
We have conducted a travel cost study with the purpose of placing a value on
conservation of cultural monuments in Armenia. The study gathered information about
trips to four cultural heritage sites—Garni, Haghardzin, Khor Virap and Tatev—by
administering a carefully designed questionnaire to domestic visitors that were
intercepted on site.
