The goal of the study was to create a way to measure how housing prices in Bucharest change over time. Researchers looked at over 15,000 housing transactions from 2013 to 2015 to do this. They found that the housing market in Bucharest is influenced by factors like how easy it is to get a loan and how many homes are available. By analyzing the prices of homes before they were sold, the researchers were able to develop a method to track changes in housing prices over time.
