17Conclusions
A synthetic screening and choice experiment is
adequate for tracing real choice processes
1
The survey proves the importance of the screening
stage for rental apartment choice
2
The screening criteria depend on individual
characteristics
3
The selection of the price criteria is related to
quality minimal requirement apartment type
4
The semi-compensatory model has an advantage in
comparison with the MNL
