MONETARY POLICY AND HOUSING PRICES BOOMS IN US: WHAT
CONTRIBUTE THE MOST NOMINAL OR REAL INTEREST RATES.
Abstract
The purpose of the present study is examine the role of the monetary policy in US housing prices
boom. Specifically, it is whether the US housing prices rise is the result of the nominal or real
interest rate fluctuations. Monthly data for the period January-2000 to December- 2015 has been
used for the empirical estimation of the results. Hodric Prescott Filter method has been used for
the stationarity of the data. Moreover, Ordinary Least Squares method, Granger Causality test
and Vector Auto Regression has been applied for the computation of the results.
Overall the main findings of the study are that nominal interest alongwith inflation and
population growth rate does contribute to the US housing Price rise. Whereas, the relationship
between the real interest rate and housing price index seems to be ambiguous. It is suggested that
the Federal Reserve can used nominal interest as an effective tool for controlling the US housing
price boom.Keywords: Housing Price Index, HP filter method, Vector Autoregression
1. IntroductionHousing sector is considered one of the important sectors of the economy. It plays a key role in
the economic activity of a country and the central banks around the world uses the benchmark
lending rate / interest rate as a monetary policy tool to regulate the economic activities. About
250 ancillary industries, such as cement, steel, brick, timber and building materials, are
dependent on the real estate industry (Singh, 2015). The housing sector plays a major role in
economic growth and stabilization through the creation of jobs in construction and materials and
demand for financial services. It also has the potential of absorbing a large number of skilled and
unskilled workforce, significantly reducing unemployment and, thereby, reducing poverty in the
country. This attribute of housing, coupled with its size and its multiplier effect on the economy,
gives it the role of a leading indicator of the imminent state of health of the economy at large
(The Ministry of Commerce, Government of Pakistan, 2006).
Housing may be considered an ordinary part of a household’s everyday life. However, it can also
be a rather complex economic phenomenon, as dwellings can have several functions. Apart from
2
being the traditional ‘roof over one’s head’, a house can serve as a source of wealth
accumulation, a valuable item for bequest motives, or a form of investment. Another distinctive
characteristic of housing is its sizeable share in household wealth, implying its importance in the
household’s decision-making process. As a result, shocks to the housing market can have a
significant impact on household behavior and on the economy as a whole (Kiss and Vadas,
2005).
Housing construction activity and productivity has been rising in Pakistan in recent years from
very low levels. However, the housing sector in Pakistan is still in its infancy when compared
with other developing and developed countries. There is a tremendous potential for growth in
Pakistan’s economy, given a relatively stable and growing economy, a rapidly increasing
population, unmet housing demand, and a growing awareness of housing finance options. There
is a need to have a well-developed housing finance market/system to help the housing sector. In
Pakistan, housing finance market is still in its nascent stage compared to other countries. At
present, twenty four commercial banks, House Building Finance Company Limited (HBFCL)
and one microfinance bank are catering to the housing finance needs (State Bank of Pakistan,
2015).
Housing price fluctuations affect private consumption as these tend to generate wealth effects
which in turn affect households’ lifetime wealth and consequently determine their spending and
borrowing plans. According to the (Boone and Girouard, 2002), housing wealth accounts for a
large share of household wealth and in some countries is the principal component of total wealth,
so the wealth effect of house price movements is expected to be stronger than that of any other
financial asset. For this reason, housing wealth may cause a higher marginal propensity to
consume than stock market wealth does (Ludwig and Slok, 2004). Furthermore, rising housing
prices tend to stimulate residential investment, thereby increasing economic activity, while
increasing real estate prices lead to increases of the value of firms’ and households’
collateralizable assets, affecting their ability to borrow and to further finance business investment
and consumption (Girouard and Blondal, 2001), with this increase in credit demand affecting
bank lending. Moreover, rising housing prices increase both banks property’s value as well as the
value of loans secured by housing collateral. Consequently, the transmission of monetary policy
may also be influenced by the housing market via its effect on the cost of capital, housing supply
and demand, households’ wealth and bank credit (Mishkin, 2007).

On contrary, the recent boom in housing prices observed in most of the developed countries
refreshed the debate that “asset prices can and do run wild at rates capable of negative effects on
real economic activity1”. The rise in the US house prices and also in other parts of the world
since 2000 has been described by The Economist magazine2 as the “biggest bubble in history”.
Since 2000 the Economist has estimated that the value of residential property in developed
countries rose by more than $30 trillion. This sharp upward tendency in housing prices has
several economic effects working through both the real and nominal sides of the economy. When
the housing prices are rising, this results in substantial increase in investment in new houses lead
to more job opportunities and economic activities in housing market but less activity in other
sectors of the economy. Similarly, when there is a rise in house prices, this increase household
wealth and consumption in the housing market against the other sectors affecting the economy.
This boom and bust in the housing prices and its adverse consequences for the economies
renewed the interest of the researchers in the debate whether the central banks should response to
it or not? The subject is debatable in the literature. Some economists’ mentioned that central
banks should only focus on its key policy goals of price stability and output growth (See,
Bernanke and Gertler,2001). However, the opposed view is that the central should use monetary
policy tools for controlling the boom and bust in housing prices. This will reduce the expected
bubbles in housing prices which will in turn reduce the risk in investments in housing market
(See, Cecchetti, et al; 2002; Mishkin, 2007). However, the literature shows that the central banks
monetary policy targeting housing market bubbles can only be effective if it focus on the drivers
bringing this up and downward trend in housing prices. But exposing the factors determining the
housing prices is also a controversial issue in the literature. Rajan (2009) showed that excessive
financial innovation resulted in the misallocation of capital to the housing sector. Whereas,
Caballero et al. (2008) and Warnock and Warnock (2009) mentioned that excessive saving in
financially weak countries led to the continuous capital inflows to the rich countries is the main
cause of housing prices bubbles in these developed world. However, other economists mentioned
that monetary policy transmission channels particularly low interest rates made the credit
cheaper and raised the demand for real state led to the higher prices in the housing market (Hume
and Sentance, 2009; Taylor, 2009).

The case of the US also became as of special interest because of its unique upward trend in
housing prices recently. This development in the housing market has attracted a renewed interest
of the policy makers and researchers on the drivers of housing prices boom in US because of its
implications for the macroeconomic performance. Specifically, a number of studies have been
carried out to answer the question whether this upward swing in the housing prices is the result
of the fed looser monetary policy? However, when we study all the previous studies conducted
for the US or other economies, most of these studies focused on the impact of housing boom or
busts on macroeconomic conditions of US economy. Similarly, some studies analyzed this
housing prices boom issue in light of the Taylor rule. Despite of all these great interests in the
issue, no effort has been made in the literature to find out whether this boom in housing prices
resulted because of the fall in the nominal or real interest? Covering this gap in the literature we
will try to answer the following research questions.
1.1 Research Questions
Q1. Are housing prices respond to the fluctuations in the nominal or real interest rate?
Q2. Is there any direct relationship b/w the nominal interest rate and housing prices or this
influence comes indirectly through the real interest rate?
Q1. Is the interest rate affect the housing prices only in short run or also in long run?
1.2 Purpose of the Study
The main purpose of the present study is to examine the role of interest rate in US housing prices
determination.
2. Review of LiteratureThe present section deals with the reviews of the studies previously conducted on the issue of
interest rate as a tool of monetary policy and its effects on house prices for different economies
with different time periods.
Phiri (2016) investigates the asymmetric pass-through effects from monetary policy to housing
prices in South Africa by using time series data collected on monthly basis from January 1967 to
December 2015. The study uses the average real house price growth and government securities
5
treasury bills as proxies for house price inflation and monetary policy instrument, respectively.
The study uses a momentum threshold autoregressive model and a corresponding threshold error
correction model (MTAR-TECM). The empirical results reveal a negative and significant
relationship between the prime interest rates and real house price inflation even though the
degree of pass-through is found to be quite low. In particular, the empirical results indicate that
an interest rate change of 1 percent will result in an opposite movement of house price inflation
of 0.02 percent.
Kuttner (2012) uses a cross-sectional regression model to evaluate the relationship between
monetary conditions and housing market. The compact form of the model he uses in the study is
of the following form;
Yi = β0 + β1rLi + β2rS
i + β3%∆MBi + β4Dieu + β5Di
em + ui
where; Y is the dependent variable which represents the real property price or the growth in
housing credit. The regressors include rS which represents the average real short-term interest
rate; rL which represents the average real lending rate and %∆MB which represents the
annualized average change in the real monetary base. Deu and Dem are the dummies used for euro-
area emerging market/transition economies. The results of the study suggest that the impact of
interest rates on house prices appears to be quiet modest while credit conditions play a larger role
in house price booms.
O’meara (2015) quantifies the extent of house price overvaluation in 10 Organization for
Economic Cooperation and Development (OECD) countries. The study specifies demand side
and supply side equations to estimate the equilibrium (fundamental) price of housing. This
approach is previously used by Muellbauer & Murphy (1997).The demand price for housing is
specified as:
Pft = αt + β1yt + β2popt – β3mortt – β4supplyt + β5rentt + ԑt
where (Pft) represents fundamental house prices which is a function of real disposable income per
capita (yt), the total population of the country (popt), the real (inflation adjusted) mortgage
interest rate (mortt), the supply on new dwellings (supplyt) and the real cost of renting a property
(rentt). The estimated supply equation is given by:
6
Supplyt = αt + β1permitt – β2costt + β3rinvt + ut
Whereas, permitt is the number of permits issued for the construction of new housing units, cost t
refers to the total cost of residential construction and rinvt refers to the real residential
investment. Error correction models are estimated for the demand and supply equations and
actual and fundamental house prices are compared then. The empirical results of the study
suggest that for some countries deviations from the Taylor rule play a role in the sudden and
great increase in house prices and that a monetary policy stance less discretionary and more
closely aligned with the Taylor rule could curtail some of the imbalances in the housing market.
Guo and Wu (2013) empirically analyze the factors affecting the housing prices in Shanghai by
employing housing demand and supply approach. The results of the study show that lending
rates and Gross Domestic Product (GDP) are the factors affecting the house prices in Shanghai
more significantly while the other variables which include the total resident population, land
price index, per capita disposable income, consumer price index and the average residential
construction costs have much less influence in driving the house prices.
McCarthy & Peach (2004) analyzes the U.S. housing market to find the existence of a national
home price bubble. They present a model of the housing market in which demand price of
housing is determined by the housing stock, permanent income of households (proxied by
nondurables and services consumption) and the user cost for which the equation is given as
follows;
Pdt = α1ht + α2ct + α3ut
While the supply price is determined by residential investment and costs of construction and the
its equation is given as follows;
Ps = γ1 ( it - ht) + γccct
The findings of the study suggest that home prices rise in line with increases in personal income
and declines in nominal interest rates. Moreover, the study suggests that house prices are less
volatile than other asset prices, such as equity prices.

Williams (2015) measures the effects of monetary policy on house prices by employing the
approach developed in Jorda, Schularick & Taylor (2015a,b) to a sample of 17 countries for the
period 1870-2013 (except for the interwar period 1914-45 and the oil crisis years of 1973-80).
The findings of the study suggest that monetary policy actions have sizeable and significant
effects on house prices in advanced economies.
Del Negro & Otrok (2007) estimate a six-variable VAR on U.S. data spanning 1986 through
2005. The variables included in the system were the house price, total reserves, Consumer Price
Index (CPI) inflation, Gross Domestic Product (GDP) growth, the 30-year mortgage rate and the
Federal funds rate. Monetary shocks were identified using sign restrictions. The main finding of
the study is that a 25 basis point expansionary monetary policy shock leads to a statistically
significant 0.9% appreciation immediately and reducing to only 0.2% after ten quarters.
Goodhart & Hofmann (2008) use a panel VAR to examine the relationship between house prices,
macroeconomic variables and other financial indicators in 17 industrialized countries. The six
variables in their model were real Gross Domestic Product (GDP) growth, Consumer Price Index
(CPI) inflation, the short-term nominal interest rate, house price growth, broad money growth
and nominal private credit growth. The results show Granger-causal relationships between many
of the variables and in particular a causal relationship from interest rates to house prices and
credit growth. The findings of the study reveal that 25 basis points orthogonalized expansionary
interest rate innovation leads to statistically significant 0.8% increase in house prices. They add
that there is no immediate impact seen rather the effect builds slowly, reaching 0.4% after 10
quarters and gradually achieving its maximum after 40 quarters. These findings are in contrast to
those in Del Negro & Otrok (2007) where their findings say that 0.9% peak occurs immediately
and vanishes rapidly.
Jarocinski & Smets (2008) presented two sets of estimates from Bayesian VARs for the U.S.: on
in levels and an alternative first-difference specification. Their nine-variable models include
output, consumption, the Gross Domestic Product (GDP) deflator, housing investment, the house
price, the short-term interest rate, the term spread, a commodity price index and the money
supply. They identify structural shocks via sign restrictions on the impulse response functions as
in Del Negro & Otrok (2007). In the levels VAR, an expansionary 25 basis point monetary
policy shock leads to gradual rise in house prices, peaking at a statistically significant 0.5% after
8
10 quarters which is accompanied by a decline in the long-term interest rate of roughly 10 basis
points. The effects subsequently diminish and 20 quarters after the shock the house price has
returned to its mean. The differenced VAR yielded somewhat larger and more persistent
estimates, but the confidence intervals are much wider, especially at longer horizons.
Sá et al. (2011) reports panel VAR results for 18 Organization for Economic Cooperation and
Development (OECD) countries from a 12-variable model, using data from 1984 through 2006.
In addition to the standard macro variables (output, the price level, consumption, non-residential
and residential investment, short- and long-term interest rates and a measure of credit), the
specification also include four variables reflecting global factors: world Gross Domestic Product
(GDP), world prices, the trade-weighted exchange rate and the current account balance. The
shocks are identified using sign restrictions just like in the studies of Del Negro & Otrok (2007)
and Jarocinski & Smets (2008). The results are in accordance with those of Jarocinski & Smets
(2008): the response to a 25 basis expansionary shock is initially slightly negative, subsequently
rising to a statistically significant but modest 0.3% effect after 10 quarters. Over a similar
horizon, the long-term interest rate declines by approximately 10 basis points. The response is
larger for countries with more sophisticated financial systems, where the response at ten quarters
is closer to 0.5%. For all countries, the effect subsequently diminishes, falling to 0.1% after 30
quarters.
Gupta and Kabundi (2009) examine the impact of monetary policy on house price inflation for
the nine census divisions. They use a factor-augmented VAR with 126 variables and find that in
general a monetary policy shock has a negative impact on house price inflation, though
heterogeneous across the nine divisions.
Gupta et al. (2010) examine the impact of monetary policy shocks on the U.S. housing sector
using a large-scale Bayesian VAR model with 143 macroeconomic variables, including 21
housing variables related to house prices and housing investment, on both the national level and
the four census regions. In order to test whether the financial market liberalization of the early
1980s has affected such impact, they split their sample in the period prior to 1982 and after 1989,
to find that the negative effect of a monetary policy shock on real house prices is larger in the
post-liberalization period at both the national and the regional level, though heterogeneous across
regions.

Christidou & Konstantinou (2011) investigate the effects of monetary policy on housing markets
of 48 U.S. states. They employ quarterly data covering the period from the first quarter of 1988
to the fourth quarter of 2009. The variables include the Federal Funds rate and a commodity
price index, real personal income, the GDP deflator, housing investment, and real house prices.
Vector Autoregressive (VAR) model is used and the findings suggest that the effects of a
contractionary monetary policy on real housing prices and housing investment are heterogeneous
across the states both in magnitude and duration.
3. Data and Methodology 3.1 Data and Definition of the Variables of the Study
The main objective of the present study is to investigate the role of the interest rate in the
determination of US housing prices. For this purpose time series monthly data over the period
January-2000 to December-2015 has been used in the present study. The data has been collected
from various sources including US Federal Housing and Finance Agency, US Bureau of Labor
Statistics, US Bureau of Economic Analysis and Federal Reserve annual reports. The detail of
all the variables used in the present study has been given in table 3.1.

In table 3.1 information about all the variables of the study has been given. The superscript “c”
on the symbols of all variables show that all these variables has been used in deviation form. For
converting the data into deviation form and extracting only the cyclical component Hodrick
Prescott(HP) filter method is used. The purpose of the application of the HP filter method to data
is to remove trend from data and making it stationary. Eviews software is used for the
computation of the results.

3.2 Model Specification
The study will follow the methodological approach developed by Mingzhen Guo and Qing Wu
(2013). The model of the study is based on the law of demand and supply as devised by the
economic theory. Housing units are transacted in the market just like the other commodities or
goods. The price of a housing unit is determined by the forces of demand and supply. The impact
of factors affecting the price directly affects supply and demand which then affects the price of
housing units. So demand and supply can be considered as the middle of the bridge in this case.
Therefore, the factors can be grouped into two separate groups i.e. factors affecting demand and
factors affecting supply of the housing prices. In other words, we can say that housing prices are
the function of housing units demand and supply.
We can setup the housing prices supply demand equation as follows;
HPrice = f (DHousing, SHousing) (3.1)
Where; HPrice represents the housing price index, DHousing represents demand for a housing unit and
SHousing represents the supply of housing units.
3.2.1Demand Equation
Firstly, the price of a housing unit is a very crucial factor to determine housing demand. If prices
are too high, the effective demand will decrease while effective demand will increase if the
prices are considerably low. Secondly, the resident population has a great influence over the
demand for housing. As the resident population increases, the demand for housing will inevitably
increase. Even if the relationship is not linear, housing demand will be affected by the increase in
population. Thirdly, the per capita annual disposable income is a direct factor in the formation of
effective demand. As long as there is a strong potential demand for housing, and there are
enough disposable income cases, the capacity to pay will turn into effective demand. Fourthly,
interest rate has a great impact on buying a house of the buyers. High interest rates and capital
costs will suppress the corresponding desire to buy a house. Instead, low loan interest rates and
low cost of capital will increase the desire to buy a house. Fifthly, Consumer Price Index
(CPI)/inflation devalue value for money. Capital owners will fund for investment to expect
11
capital preservation and appreciation, and investing commodity housing is a good choice. Based
on the above mentioned factors, now we build housing demand function, as follows:
DHousing = f (HPrice, POP, GDP, INT, INF) (3.2)
Whereas,
HPrice = Housing Price
POP = Total Population/Population Growth Rate
GDP = Gross Domestic Product
INT = Interest Rate
INF = Inflation Rate
3.2.2Supply EquationFirstly, when housing prices are high, developers will increase supply while there will be a
reduction in the supply if housing prices are low. Secondly, benchmark lending rate or interest
rate is directly related to the cost of the developer’s use of loan funds. When the interest rate /
lending rate is high, the corresponding cost is also high. So that investment in housing
construction decreases and developer reduces the quantity. On the contrary, when interest rate /
lending rate is low, the corresponding cost will be low and the investment in housing
construction will increase which means greater supply of housing units by the developer.
Thirdly, the price of land constitutes a large part of housing construction costs. With high land
costs, developments costs are high, in the case of limited development funds; the supply of
housing is reduced. Fourthly, when the cost of housing construction is high, the developer
decrease the housing supply and increases if the cost of housing construction is low. Fifthly, as
the Gross Domestic Product (GDP) increases, the reflection on infrastructure and real estate
development increases with a corresponding increase in supply.
Based on the above factors, the supply of housing construction is given as follows;
SHousing = f (HPrice, GDP, INT) (3.3)
Whereas,
HPrice = Housing Price
GDP = Gross Domestic Product
INT = Interest Rate
12
3.2.3Housing Price Model
Economic theory shows that factors affecting the price directly affect demand and supply and
then affects the price, so demand and supply is the middle of the bridge. Therefore, these factors
can be grouped into the factors affecting demand and affecting supply. Hence, from equation
(3.1) we knew that we can write housing prices is the function of housing demand and supply.
HPrice = F (DHousing, SHousing)
Now for obtaining the housing price equation we put equation (3.2) and equation (3.3) into equation (3.1).
Hence, we get the following general form of the housing price model.
HPrice = f (HPrice, POP, GDP, INT, INF) (3.4)
Now because the specific purpose of the current study is to examine whether US housing price is affecting by the nominal interest or the real interest. Hence, for the empirical estimation we have used the following two modified versions of the housing price model into equation form.
3.2.3.1 Housing Price Model with Nominal Interest Rate
HPC = 𝛼0 + 𝛼1INTC + 𝛼2INFC + 𝛼3POPGC + 𝛼4GDPC + ε1 (3.5)
Equation (3.5) shows the Housing price model with nominal interest rate. Here in this equation we have included nominal interest rate. However, we have excluded the real interest rate from the model. In the model HPC has been used as dependent variable. Whereas, POPGC, GDPC, INTC and INFC has been used as independent variables. Moreover, 𝛼0, 𝛼1, 𝛼2, 𝛼3 and 𝛼4 are the relevant coefficients and ε1 is the error term.
3.2.3.2 Housing Price Model with Real Interest Rate
Now for examining the role of the real interest rate in the US housing prices, we have excluded nominal interest rate and inflation rate from equation (3.5) and included the real interest rate. This new model is showing by equation (3.6).
HPC = 𝛽0 + 𝛽1RINTC + 𝛽3POPGC + 𝛽4GDPC + ε2 (3.6)
Equation (3.6) shows the housing price model with real interest rate. In the model HPC has been used as dependent variable. Whereas, POPGC, GDPC and RINTC has been used as independent variables. Moreover, 𝛽0, 𝛽1, 𝛽2 and 𝛽3 are the relevant coefficients and ε2 is the error term.

4. Results and Discussions
The results of the study is divided into two main parts i.e. section 4.1 and section 4.2. First, in
section 4.1 results for the housing price model with nominal interest rate has been computed.
For showing the role of the nominal interest rate in the US housing price different econometric
techniques including Ordinary Least Squares, Granger Causality Test and Vector Auto
Regression has been applied. Similarly, section 4.2 shows the results of our housing price model
with real interest rate. For examining the role of the real interest rate in the US housing price
Ordinary Least Squares, Granger Causality Test and Vector Auto Regression has been used.
4.1. Results of Housing Price Model with Nominal Interest Rate
For investigating the role of the nominal interest rate in the US housing price Ordinary Least
Squares method has been applied. The regression results computed has been given in section
4.1.1.

In table 4.1 we have estimated four regression results i.e. Regression-1, Regression-2,
Regression-3 and Regression-4. The main purpose behind the computation of the regression
results for the various versions of our housing price model is to examine the importance of all of
our explanatory variables in our housing price model.
First, in regression-1 we have included only the nominal interest rate as explanatory variable in
our housing price model. All other explanatory variables has been excluded from the model.
Regression-1 results shows that the coefficient of the nominal interest rate turned positively
significant at 5% level of significance. However, the sign of the nominal interest rate is positive
which is against our expectations. One reason for this can be the exclusion of other important
variables from the model. Moreover, R-square and Durbin Watson statistic values are also very
low showing the significance of the missing variables in our model. Similarly, Regression-2
results has been computed by including inflation rate in the model. The results show that
nominal interest rate is positively significant. However, inflation remained insignificant. The R-
square value is 0.49 which shows that overall the fit is not good. Similarly, the Durbin Watson
statistic value is 0.81 showing the autocorrelation problem in the model. After that Regression-3
has been computed by including population growth rate as additional explanatory variable in the
model. The results show that inflation and population growth rate turned positively significant.
However, turned significant but with a positive unexpected sign. Here, the R-square value is 0.51
and the Durbin Watson statistic value is 1.23. Finally, we have included another explanatory
variable real Gross Domestic Product in the model and computed regression results which is
showing by regression-4 in the table. The results show that all the explanatory variables i.e.
nominal interest rate, inflation rate and population growth rate turned positively significant.
However, the real Gross Domestic Product turned insignificant. In the model the R-square value
is 0.57 showing that 57% variation in the dependent variable is explaining by all the independent
variables. Furthermore, the Durbin Watson statistic value is 1.67 showing that the reliability of
the results.
4.1.2. Granger Causality Results of the Housing Price Model with Nominal Interest Rate
In time series analysis the Granger causality test is widely used to know whether in the time
series data one variable can forecast the other time series variable. The model is first proposed in
15
1969 by Granger (1969). Ordinarily, regressions reflect "mere" correlations, but Clive Granger
argued that causality in economics could be reflected by measuring the ability of predicting the
future values of a time series using past values of another time series. Since the question of "real
causality" is deeply philosophical, econometricians assert that the Granger test finds only
"predictive causality" (Diebold, 2001).
The Granger Causality test results are given in table 4.2 as follows.

The Granger Causality test results show that nominal interest rate shows a uni-directional
relationship with the housing price index. Similarly, inflation with nominal interest rate, Gross
Domestic Product with inflation rate and nominal interest rate with Gross Domestic Product also
show a uni-directional relationship. All other hypothesis for other variables cannot be rejected
because the P-value turned insignificant for these variables.
4.1.3. VAR Results of the Housing Price Model with Nominal Interest Rate
Table 4.3 to table 4.8 shows the VAR results. First we have checked the individual significance
of the variables for each model of the whole system equation. Then, we have computed the Joint
16
significance of all the variables of different models by using the Wald test. Finally the Cholesky
decomposition test is used for the computation of impulse response functions.
4.3.1.1: Individual Significance of the Variables of VAR Model
The individual significance of the explanatory variables has been checked for all the five models
of the system i.e. Housing Price Model, Population Growth Model, Gross Domestic Model,
Inflation Model and Interest Rate Model.
First, the Housing Price model shows that four variables lag variables of housing price index
and nominal interest rate turned significant in the model. Whereas, other variables in the model
remained insignificant. Similarly, in the population growth model lag values of the population
growth rate, inflation rate and interest rate turned significant. Moreover, in the Gross Domestic
Product model lag variables of the Gross Domestic Product remained significant. Whereas, all
other variables turned insignificant. Furthermore, in the inflation rate model lag values of the
population growth rate, Gross Domestic Product and inflation rate became significant. Finally in
the interest rate model lag variables of the housing price index, population growth rate, inflation
rate and nominal interest rate turned significant.
Overall, the nominal housing price index model shows the role of the nominal interest in the
determination of the US housing prices.

4.3.1.2: Joint l Significance of the Variables of VAR Model
The joint significance of the variables has been checked by using the Wald test.
The individual significance of the explanatory variables has been checked for all the five models
of the system i.e. Housing Price Model, Population Growth Model, Gross Domestic Model,
Inflation Model and Interest Rate Model. The overall significance of all the five models i.e.
housing price index, population growth rate, Gross Domestic Product, inflation rate and nominal
interest rate has been estimated. The results computed are given in tables 4.4, 4.5, 4.6, 4.7 and
4.8 respectively. By applying the Wald test for showing the joint significance of the explanatory
variables in all the five models we have put zero restriction on the explanatory variables with the
hypothesis that these all these explanatory variables doesn’t influence the dependent variables.
However, all of these hypotheses have been rejected and it is confirmed that all the explanatory
variables in all the models does influence the explained variables.
From the housing price index model it is clear that nominal interest rate does play role in the
determination of the US housing price rise.

4.3.1.3: Impulse Response Function Results of VAR Model
20
Cholesky decomposition is used for examining the response of the dependent variables to
independent variables in all the five models. The results are given in figure 4.1 as follows.
Figure. 4.1: Impulse Response Function Results
The results shows that housing price index in the first model is affected by affected by the shocks
from all the explanatory variables i.e. lag housing price index, population growth rate, Gross
Domestic Product, inflation rate and nominal interest rate.
Similarly, the models of population growth rate, Gross Domestic Product, inflation rate and
nominal interest rate also shows the affect of the shocks on the dependent variables from the
independent variables.

4.2. Results of Housing Price Model with Real Interest Rate
For investigating the role of the real interest rate in the US housing price Ordinary Least Squares
method has been applied. The regression results computed has been given in section 4.9.

In table 4.9 we have estimated three regression results i.e. Regression-1, Regression-2 and
Regression-3. The main purpose behind the computation of the regression results for the various
versions of our housing price model is to examine the importance of all of our explanatory
variables in our housing price model.
22
First, in regression-1 we have included only the interest rate as explanatory variable in our
housing price model. All other explanatory variables has been excluded from the model.
Regression-1 results shows that the coefficient of the real interest rate turned negatively
significant at 5% level of significance. Moreover, R-square value is 0.25 and the Durbin Watson
statistic value is 0.23 showing the significance of the missing variables in our model. Similarly,
Regression-2 results has been computed by including population growth rate in the model. The
results show that real interest rate is significant but with unexpected positive sign. However,
population growth rate and intercept remained insignificant. The R-square value is 0.36 which
shows that overall the fit is not good. Similarly, the Durbin Watson statistic value is 0.97
showing the autocorrelation problem in the model. Finally, Regression-3 has been computed by
including Gross Domestic Product as additional explanatory variable in the model. The results
show that real interest rate turned significant with the expected negative sign. However, all the
coefficients of all other variables i.e. population growth rate, Gross Domestic Product and
intercept remained insignificant. Here, the R-square value is 0.49 and the Durbin Watson statistic
value is 1.37.

The Granger Causality test results show that two variables i.e. housing price index and Gross
Domestic Product showed a uni-directional relationship with the real interest rate. However,
23
other hypothesis for all other variables cannot be rejected because the P-value turned
insignificant for these variables.
4.2.3. VAR Results of the Housing Price Model with Real Interest Rate
Table 4.11 to table 4.15 shows the VAR results. First we have checked the individual
significance of the variables for each model of the whole system equation. Then, we have
computed the Joint significance of all the variables of different models by using the Wald test.
Finally the Cholesky decomposition test is used for the computation of impulse response
functions.
4.3.2.1: Individual Significance of the Variables of VAR Model
The individual significance of the explanatory variables has been checked for all the four models
of the system i.e. Housing Price Model, Population Growth Model, Gross Domestic Model and
Real Interest Rate.
First, the Housing Price model shows that two lag variables of housing price index turned
significant in the model. Whereas, other variables in the model remained insignificant.
Similarly, in the population growth rate model and Gross Domestic Product models only lag
values of the population growth rate and Gross Domestic Product turned significant. Finally, in
the real interest rate model lag values of the Gross Domestic Product and real interest rate
remained significant whereas, all other variables turned insgificant.

4.3.2.2: Joint l Significance of the Variables of VAR Model
The joint significance of the variables has been checked by using the Wald test.
The significance of the explanatory variables has been checked for all the five models of the
system i.e. Housing Price Model, Population Growth Model, Gross Domestic Model and Real
Interest Rate Model. The overall significance of all the four models i.e. housing price index,
population growth rate, Gross Domestic Product real interest has been estimated. The results
computed are given in tables 4.12, 4.13, 4.14 and 4.15 respectively. By applying the Wald test
for showing the joint significance of the explanatory variables in all the four models we have put
zero restriction on the explanatory variables with the hypothesis that these all these explanatory
variables doesn’t influence the dependent variables. However, all of these hypotheses have been
rejected and it is confirmed that all the explanatory variables in all the models does influence the
explained variables.

4.3.2.3: Impulse Response Function Results of VAR Model
Cholesky decomposition is used for examining the response of the dependent variables to
independent variables in all the four models. The results are given in figure 4.2 as follows.
Figure. 4.2: Impulse Response Function Results

The results show that housing price index in the first model is affected by the shocks from all the
explanatory variables i.e. lag housing price index, population growth rate, Gross Domestic
Product and real interest rate. Similarly, the models of population growth rate, Gross Domestic
Product, real interest rate also shows the affect of the shocks on the dependent variables from the
independent variables.
Conclusion
We have examined the role of the Federal Reserve monetary policy in the US housing price
boom. The specific focus of the study was on to investigate the role of nominal and real interest
rate in the determination of the US housing prices.Monthly data for the period January-2000 to
December- 2015 has been used for the empirical estimation of the results. Hodric Prescott Filter
method has been used for the stationarity of the data. Moreover, Ordinary Least Squares method,
Granger Causality test and Vector Auto Regression has been applied for the computation of the
results.
Overall, the results showed that nominal interest alongwith inflation and population growth rate
does contribute to the US housing Price rise. Whereas, the relationship between the real interest
rate and housing price index seems to be ambiguous. It is suggested that the Federal Reserve can
used nominal interest as an effective tool for controlling the US housing price boom.
