The Cox proportional hazards model in the analysis of property transactions

The main aim of the paper is to present the methodological basis of housing transactions which uses duration analysis and Cox’ proportional hazards model. The study will take into consideration single episodes with one starting point (the purchase of a flat on the resale market) and one final point (selling the flat to another owner). The analysis has covered over 1016 transactions concerning the sale and purchase of cooperative flats in 2000-2009, including repeated transactions. For each of the transactions the date, the initial and final prices as well as the basic parameters of a flat have been given. For each of the transactions the date, the initial and final prices as well as the basic parameters of a flat have been given. The study will verify the hypothesis of the high probability of the existing owner to have further ‘lasting right’ to the flat, i.e. the correlation within times of event (sell flat) and the basic parameters of a flat.
