International developments in
housing markets – lessons for
Sweden
E Philip Davis
National Institute
of Economic and
Social Research
Introduction
• In this presentation we seek to give an overview
of recent developments in housing markets for 12
OECD countries, via data and relevant research
• We begin by noting key structural differences,
before looking at developments in the crisis
• We proceed to put these in a longer term context
• And finally look at key implications of house prices
for investment, consumption, public finance and
financial stability/financial regulation
Background – structural features
• Housing markets cannot be treated as
homogeneous
• Population density is correlated with dwelling
size and availability of land, although the latter is
also affected by planning restrictions
• Dwelling size and inhabitants per dwelling is
indicators of living standards in terms of housing
• Interest rate risk may affect both supply and
demand for housing, and demand may also be
affected by the prevalence of fixed rate loans

Recent house price developments
• Boom-bust cycle in housing in a number of
countries…
• US housing credit linked to global crisis directly
via falling CDO prices (note principal agent
problem in US mortgage securitisation)
• Since crisis, house price falls less marked than
widely expected, recovery in some countries
• Evidence of further financial distress with high
level of arrears and repossessions in countries
such as the US
• Less so in those such as the UK as interest
rates low and house price falls modest – and
loans recourse based

A longer term perspective
• Boom in house prices following liberalisation in
the 1980s, often leading to banking crises…
• Long term rise in real house prices (higher
income, shortage of land) – implicit
intergenerational transfers (Weale 2007)
• Rise in debt-income ratios to households
correlated with rise in house prices (house
purchase but also equity extraction)
• But credit should not drive house prices in
liberalised financial system (conventional
determinants are income, interest rates, supply
conditions, demographics, see e.g. Muellbauer
and Murphy 1997))

Housing and investment
• Housing investment typically a small proportion
of the stock, given houses are long-lived assets
• Overall housing investment has tended to
decline as a proportion of GDP in a number of
countries, even before 2008/9 when sharp falls
especially Spain and Ireland
• Key determinant Q ratio (house prices/housing
investment deflator) (Jud and Winkler (2003),
Berg and Berger (2005))
• Correlation of house price change to
investment/GDP change in 2008/9 is 0.73

House prices and consumption
• Research on wealth effect shows strong link
from house prices/housing wealth to
consumption (e.g. Barrell and Davis (2007),
Case et al (2005)), although effect on nonhomeowners should partly offset
• Simple cross section regression shows house
prices discriminated the falls in consumption
between 2008/3 and 2009/4 better than equity
prices, although RPDI and lagged debt/income
also relevant
• Collateral effect likely intensified by credit
rationing, but banking crisis dummy not
significant

Housing and fiscal position
• NIER (2010) decomposed deterioration in
fiscal position into cycle, policy changes,
bank support and residual
• Residual linked partly to revenue from
financial sector but also housing market
• Falling house prices affect tax revenues
directly (via stamp duties and profits of
construction/realtor sector) and indirectly
(via consumption taxes – to the extent
consumption fell more than in a normal
cycle)

House prices and banking crises
• Barrell, Davis, Karim and Liadze (2010) in JBF and
subsequent work were first to find role for bank
capital and liquidity in OECD crisis models
• House price bubbles matter
• Sustained deficits matter
• Using logit model together with a banking sector
sub-model of NiGEM global macro model enabled
assessment of overall costs and benefits of
regulation in the UK – optimal level of tightening
(Barrell et al (2009) FSA OP)
• Recent work looks at the split between on balance
sheet and other revenues (OBS)
• Level of OBS does not matter as it varies across countries a lot
• Faster growth of OBS activity boosts crisis probabilities
Calibrating macroprudential surveillance
• In “Calibrating macroprudential surveillance” we
put in all ‘normal’ variables including lagged
house price rises and test down with 14 OECD
countries, 12 crisis and data for 1980 to 1997
(vastly shorter sample than earlier work)
• As in earlier work, found that “traditional”
variables such as credit growth, output growth
and M2/reserves less relevant to OECD –
artefact of dominance of global samples by
emerging markets
• A researcher undertaking this work in the late
1990s could have picked the same equation
Explaining OECD Financial Crises
• We explain crisis probabilities (logit) in OECD

Model character
• Up to four lags tried in house prices, credit
growth, current account and GDP growth
– Cyclical variables drop out
– Lending growth drops out
• Lending quality matters with house price growth
and current balances as indicators

Using the model in macroprudential
policy setting
• We can invert the probability model to calculate
the additional levels of liquidity and leverage
required for the probability of a crisis to be 0.01
in each country and year
– Re-estimate each year from 1997, predict one year
– Raise capital and liquidity to get probability 0.01
• Capital and liquidity form the defences, while
house prices and current balances are the
problems we need to provision against, not
cycles or credit.
• Separate result shows credit does not Granger
cause OECD house prices either (except
Belgium, Canada and Finland)
Country and aggregate targets
• Country max
reduces
probability to
0.01 in worst
year
• The average of
these could be
used as a
criterion
• Major cross
country
differences in
warranted
tightening

Countercyclical provisioning
• Has to be calibrated on house prices and

Conclusion
• Caution needed in directly comparing housing
markets due to structural differences
• Housing finance clearly at core of recent financial
crisis – US housing loans packaged into CDOs and
recent defaults following price falls
• Falls in house prices can be related inter alia to
changes in consumption, housing investment and
fiscal deficits since the crisis
• And clear relation of lagged house price increases
to OECD banking crises – relevant to ongoing bank
regulation reform also
• Key lesson for Sweden is to avoid boom-bust
cycle in housing, given macroeconomic volatility
and systemic financial risk it generates – and
long term intergenerational implications
• Control could be via appropriate monetary and
macroprudential policies (including control of
LTVs) – possibly also planning regulations
• If using securitisation ensure system is
transparent and incentive compatible
• Ensure banks have sufficient capital as well as
countercyclical reserves based on trends in
house prices (not credit per se)
