Motivation for the research
•
Despite its leading position in Europe, limited
research on the Greater Paris rental office market
•
Analysis of the Parisian market dynamics (focus on
the rental and demand equations)
•
Extend the existing office market research to the
French case to the really recent past
•
Combine cointegration techniques to a multiple
structural break approach

MODELING STRATEGY
13/04/2015
ERES 2014 - Bruneau C. and Cherfouh S.
4
Literature and methodology
•
Theoretical background  multi-equation framework
[Rosen, 1984]; [Wheaton, 1987];
[Wheaton et al. 1997]; [Malle 2010] etc
•
Objective: provide a full comprehension of the main
underpinning market dynamics
•
3 behavioural equations:



Demand:(economic activity and rents)
Supply:(economic activity, vacancy rate, construction
costs, interest rates)
Rents:(vacancy rates)

ERES 2014 - Bruneau C. and Cherfouh S.
5
Literature and methodology
•
Econometric methodology  cointegration approach
[Hendershott et al. 2002]; [Brounen and Jennen, 2009];
[McCartney, 2012]; [Hendershott et al., 2013] etc
Reduced-form equations
•
Justification: most economic, financial and real estate
series are non stationary
•
Objective: provide a relevant framework able to
account for specific characteristics of space markets
 well-known slow adjustment

Literature and methodology
•
Econometric methodology  multiple structural break
approach
[Perron, 1989]; [Banerjee and Urga,1995]; [Gregory and Watt,
1996]; [Gregory and Hansen, 1996]
•
Justification: no cointegration found between the
variables of interest
•
Objective: account for the structural changes that may
affect the long run equilibria through shifts in the mean
Nonlinear approach in the space market literature
[Englund et al. 2008]; [Brounen and Jennen, 2009]; [Hendershott
et al., 2010]; etc

THE GREATER PARIS
OFFICE MARKET
13/04/2015
ERES 2014 - Bruneau C. and Cherfouh S.
10
The Greater Paris office market
•
Largest office market in Europe in terms of stock (53 m sm) and
in terms of turnovers (over 2 m sm take-up/annum since 2000)
•
Second largest market in terms of investment after London
(€ 9.6 b/annum since 2000 vs 11.8 for London)
•
Major market with specific characteristics compared to the
London market:
 Higher level of office space centralization in France
 Economic growth prospects strongly reliant on a relatively

stable private and public demand
Shorter terms of rental agreements

EMPIRICAL RESULTS

ERES 2014 - Bruneau C. and Cherfouh S.
14
Estimation procedure
 Three-step procedure:
1. Structural break identification  pragmatic approach:
 No closed-form solutions for the limiting distribution of the unit root test


statistics in the case of multiple breaks
Graphical examination of the long-run residuals  choice of the dates
that best corresponds to changes in the mean of the residual.
Critical values obtained from Monte Carlo simulations.
2. FMOLS estimation of the cointegrating relationships for both
sub-systems with their respective breaks.
3. OLS estimations of the ECM within each sub-system

Conclusion and future work
•
Results summary:
 Justified structural breaks
relationships

Error correction approach confirmed as relevant to model
space market


•
allow us to capture cointegrating
Settles the traditional drivers of rents and demand in the long-run
Characterizes their role in the short-run  outlines the rigidities
specific to the market structure
On going work:
 Submarket analysis
 dynamics and interactions between
Parisian submarkets (Stevenson (2007), Ke and White (2014))
