European Real Estate Society Annual Conference Bucharest, 2014 Long-run equilibrium for the Greater Paris Office Market ; Rental and Demand adjustments Catherine Bruneau* and Souad Cherfouh** * Professor, University Paris I Pantheon Sorbonne and Paris School of Economics ** PhD student, University Paris I Pantheon Sorbonne and BNP Paribas Real Estate INTRODUCTION 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 2 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 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 3 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) 13/04/2015 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 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 6 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 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 7 Rent modeling • (1) (2) 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 8 Demand modeling • Long-run model: (3) • Short-run model: (4) 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 9 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 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 11 Vacancy and rental movements Figure 2: Real rent and vacancy rate in the Greater Paris office market (1991-2012) % Index 130 11 120 10 110 9 100 8 90 7 80 6 70 5 60 4 50 3 40 2 1992 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 Real effective rent (new leases) Vacancy rate 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 12 Movements in office demand fundamentals Figure 3: Occupied stock and real rents in the Greater Paris office market (1991-2012) Figure 2: Occupied stock and office employment in the Greater Paris office market (1991-2012) % % 6 6 5 5 4 4 3 3 2 2 1 1 0 0 -1 -1 -2 -2 1992 1994 1996 1998 2000 2002 2004 2006 Occupied stock (annual variation) Office employment (annual variation) 13/04/2015 2008 2010 2012 % Index 110 5 100 4 90 3 80 2 70 1 60 0 50 -1 1992 1994 1996 1998 2000 2002 2004 2006 2008 2010 2012 Occupied space (annual variation) Real effective rent (new leases) ERES 2014 - Bruneau C. and Cherfouh S. 13 EMPIRICAL RESULTS 13/04/2015 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 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 15 Rent modelling Table 1: Long-run equilibrium rent model Variable Vacancy rate Coefficient Coefficient for vacancy rate: significant and expected sign • All breaks are justified by referring to recent developments of the parisian market ; the related coefficients have the expected signs. • For example: t-Statistic -0.08*** -0.26*** -16.3 -10.9 -0.15*** -4.9 0.27*** 12.5 -0.13*** -6.5 0.06*** 3.0 Intercept 5.07*** 109.9 N 88 Adjusted R² 0.93 Notes: Dependent variable = ln(Real Rent). *, **, *** indicate significant at 10%, 5% and 1% respectively. 13/04/2015 • 1994Q4 → sharp rent correction consecutive to the bubble burst in the early 1990’s 2000Q4 → demand crisis: 2% vacancy rate for « relatively low » rental values → correction in the distorsion ERES 2014 - Bruneau C. and Cherfouh S. 16 Rent modelling Table 2: Short-run adjustement model Variable Coefficient -0.04 *** -6.0 ln(Rent(-3)) -0.32 *** 3.4 Error correction term -0.29 *** -4.2 Intercept -0.00 -0.9 Durbin-Watson 84 Adjusted R² Error correction term is significant ; long run causality from the vacancy rate towards the rent (Granger, 1988) • Speed of rental adjustement = 29% • Relatively high speed of adjustement compared to other European markets t-Statistic Vacancy rate(-2) N • 0.55 2.16 Notes: Dependent variable = ln(Real Rent). *, **, *** indicate significant at 10%, 5% and 1% respectively. 13/04/2015 • Shorter lease lenght Higher market turnover Autoregressive structure of the rents ERES 2014 - Bruneau C. and Cherfouh S. 17 Demand modelling Table 3: Long-run demand model Variable ln(Office employment) ln(Real rents) Intercept N equilibrium Coefficient 23.1 -11.2 -7.3 0.02*** 4.3 -0.02*** -4.7 0.01*** 3.5 -0.02*** -3.6 0.02*** 5.0 12.87*** 70.0 Adjusted R² 0.99 Notes: Dependent variable = ln(Occupied Space). *, **, *** indicate significant at 10%, 5% and 1% respectively. 13/04/2015 Coefficients for employment and rents: significant and expected signs • All breaks can be interpreted and the related coefficients have the expected signs • For example: t-Statistic 1.10*** -0.12*** -0.05*** 87 • 1993Q3 → downwards correction in the supply crisis context 2001Q3 → downwards demand correction relative to changing economic conditions 2007Q4 → financial crisis impact ERES 2014 - Bruneau C. and Cherfouh S. 18 Demand modelling Table 5: Absorption adjustement model Variable Coefficient t-Statistic Occupied Space(-1) 0.31*** 3.3 Occupied Space(-2) 0.28*** 2.7 Error correction term Intercept N Durbin-Watson -0.09* • Error correction significant • Slow speed of adjustement = 9% • Space absorption is sticky due to rigidities -1.8 0.00*** 85 Adjusted R² term is space 2.7 0.23 1.93 Long-term term leases Costs associated with termination lease Notes: Dependent variable = ln(Occupied Space). *, **, *** indicate significant at 10%, 5% and 1% respectively. 13/04/2015 ERES 2014 - Bruneau C. and Cherfouh S. 19 International comparison Table 4: Elasticity estimates for selected European office markets Market Authors Paris Price elasticity Income elasticity Sample period and frequency Specification estimation -0.12 1.1 1991-2012 𝑙𝑛𝑂𝑆𝑡∗ = 𝛼0 + 𝛼1 𝑙𝑛𝐸𝐴𝑡 + 𝛼2 𝑙𝑛𝑅𝑡 + 𝑖 𝜎𝑖 𝐷𝑈𝑀𝑖 + εt ECM Office employment quarterly and Economic activity proxy 12 European markets Mouzakis and Richards (2007) -0.15 0.63 1980-2001 annual panel data 𝑙𝑛𝑅𝑡∗ = 0 + 1 𝑙𝑛𝐸𝐴𝑡 + 2 (𝑙𝑛𝑆𝑡 − 𝑣) + εt ECM Local gross added Paris Malle (2010) -0.19 0.97 1996-2008 quarterly 𝑙𝑛𝑂𝑆𝑡∗ = 𝛼0 + 𝛼1 𝑙𝑛𝐸𝑡 + 𝛼2 𝑙𝑛𝑅𝑡 + εt OLS Office employment London Hendershott et al.
