There are, by now, several long term, time series data sets on important housing & macro
variables, such as land prices, house prices, and the housing wealth-to-income ratio.
However, an appropriate theory that can be employed to think about such data and associated
research questions has been lacking. We present a new housing & macro model that is
designed specifically to analyze the long term. As an illustrative application, we demonstrate
that the calibrated model replicates, with remarkable accuracy, the historical evolution of
housing wealth (relative to income) after World War II and suggests a further considerable
increase in the future. The model also accounts for the close connection of house prices to
land prices in the data. We also compare our framework to the canonical housing & macro
model, typically employed to analyze business cycles, and highlight the main differences.
The IMF Working Papers series is designed to make IMF staff research available to a wide audience. Almost 300 Working Papers are released each year, covering a wide range of theoretical and analytical topics, including balance of payments, monetary and fiscal issues, global liquidity, and national and international economic developments.
