HOUSING AND THE MACROECONOMYTHE ITALIAN

The Macroeconomics of housing markets
Session 1A Housing and the business cycle -
Domestic features
  • Paris, 3-4 December 2009

Bank of Italy, Department of Economic Outlook
and Monetary Policy Studies

Motivations
  • Rising housing prices, indebtedness and
    imbalances (graphs)
  • Real house prices in Italy have increased by 40
    since last cyclical trough
  • Households debt (as of GDP) has doubled in the
    last 10 years
  • Local nature of housing markets, cross-country
    heterogeneity (graphs)
  • High home-ownership rate (72)
  • Low (but increasing) level of indebtedness of
    Italian households
  • Incomplete housing finance markets (products
    variety, transaction costs)
  • Empirical evidence
  • Existing empirical evidence mainly focused on
    Anglo-saxon countries

3
Aim of the paper
  • Searching for stylized facts of the Italian
    housing market
  • Over the cycle growth cycle approach
  • In reaction to a monetary policy shock SVAR
    analysis

4
The Housing market Cycle descriptive statistics
5
The Housing market Cycle GC approach
  • Focus on cycles as deviationd from trend
  • Cycle defined as fluctions with period between 3
    and 10 years as shortest cycle is 26 quarters and
    longest is 46 quarters
  • Use of band pass filter (Baxter and King)

6
The Housing market Cycle Synchronization I
  • Lead/lag relationships analyzed through
    cross-correlations
  • Residential investment leads real house price by
    3 quarters
  • GDP and demand components (C and I not shown)
    lead house price by 7 quarters
  • Inflation and policy rate lead house price by 1
    and 3 quarters

7
The Housing market Cycle Synchronization I
  • Lead/lag relationships analyzed through
    cross-correlations
  • GDP and demand components (C and I not shown)
    lead res. inv. by 2 quarters
  • Inflation and policy rate lag house res. inv. By
    1 and 4 quarters

8
The Housing market Cycle Synchronization II
  • Lead/lag relationships
  • analyzed through cross-
  • concordance
  • Residential investment lead real house price by 5
    quarters
  • GDP and demand components (C and I not shown)
    lead house price by 7 quarters
  • Inflation and policy rate lead house price by 5
    and 1 quarters

9
The Housing market SVAR analysis I
  • VARIABLES
  • Endogenous CPI, GDP, Nominal House price index
    (PH), real residential investment (INV), Policy
    rate (P.rate)
  • Exogenous dummy variables, World commodity price
    index
  • DATA
  • Quarterly data 1990-2008
  • All variables (except policy rate) in log-levels
  • IDENTIFICATION
  • Recursive (Cholesky)
  • Sign restrictions on impulse-reponses
  • Notes
  • In the following graphs, the response of real
    house price is obtained by construction
  • P. rate is the bank of Italy repo rate until
    1999 and rate on main refinancing operation of
    ECB from 1999

The Housing market SVAR analysis

At business cycle horizons, monetary policy
shocks account between 10 and 15 of variance of
residential investment and around 10 of variance
of nomina house price but less then 10 of
variance of real house prices
14
Conclusions
  • To summarize
  • Housing cycles are longer than cycles in macro
    variables
  • Housing cycles are asymmetric in terms of
    duration, intensity and price adjustment
  • GDP and components lead housing cycle
  • Inflation and interest rates are more coincident
  • Monetary policy shocks have modest but
    significant and long-lasting effects on housing
    variables (maximum impact between 0.2 and 1 for
    res. investment and between 0.1 and 0.5 for
    real house price)
  • Monetary policy shocks explains around 10-20
    percent of variability of housing variables at
    the 2-5 years horizons their role is
    insignificant at shorter horizons
