Measuring Rent Affordability and its Regional Gap in Korea

We design a new frame on measuring rent affordability considering the level of income and wealth of a household by region since it is problematic to directly adopt several methods of measuring housing and rent affordability devised in aboard due to complicatedly segmented rent system such as regular monthly rent, joense (key money deposit), and monthly rent with lump-sum deposit etc. in Korea. By applying this novel approach on rent market, it enables us to visualize affordability and to quantify its degree by so-called rent affordability distribution curve and score respectively. We find that rent affordability is distinctly differentiated by region, income and wealth of a household but rent affordability is widely increasing in all regions over the sample period 2012-16.
