Abstract:

In recent years, the scale of China's household debt continues to grow. At the same time, China's housing prices and real estate investment show a rapid upward trend, while the growth rate of GDP, consumption and fixed asset investment has decreased to varying degrees. This is the phenomenon of “shifting from real to fictitious”. It intends to interpret the above economic phenomenon from the perspective of housing price expectation in this paper. Based on the statistical data from 2007 to 2019, it is found that: household debt continues to increase, but the volatility is small; household debt and the main macroeconomic variables show a weak positive correlation. Then a DSGE model is built which including heterogeneous households, credit constraints and GHH utility function. Numerical simulation shows that under the impact of technology shock and weak expectation shock of housing price rising, the model can explain the cyclical characteristics of household debt, real estate market and real economy. When the wealth effect of technology shock is greater than the speculative effect of weak expected shock of house price rising, the wealth effect dominates, the total demand increases, and the household debt forms a positive co-movement with the real estate market and the real economy. If the expectation of house prices rising becomes stronger, speculative effect will dominate, and household debt, real estate market and real economy will move in reverse. Once a strong expectation of rising house prices is formed and speculative effect is dominant, household debt will restrain aggregate demand and crowd out the real economy. And then household debt, house prices and real estate investment will rise rapidly, while GDP, consumption and fixed asset investment will decline. That is to say, household debt, real estate market and real economy will move in reverse, and credit constraints will have amplification effect. The counterfactual simulation shows that the strong expectation of house price rising will lead to the problem of “shifting from real to fictitious”. And then the strong expectation of house price falling has significant “deleveraging” and tightening effect on household debt and real estate market. Therefore, the expectation of house price stable can avoid the ups and downs of the macro-economy, which is conducive to the smooth operation of the macro-economy.

Key words: household debt, shifting from real to fictitious, stable expectation, wealth effect, speculative effect
