The study looked at how house prices and household debt affect economic growth in OECD countries. They used data from 2007 to 2017 and found that GDP per capita is significantly related to house prices, household debt, and inflation. Population and interest rates didn't have a significant impact on economic growth. The researchers suggest that policymakers should control property prices to prevent asset bubbles and recommend including more variables like household income and interest rates on housing loans in future studies.
