Introduction • Methodology • Model • Impact of global volatility • Implications of modelling output
Introduction Methodology • Previous model (Hicks & McGough 2005) provided a framework for our yield analysis • Previous equation looks at impact of • Rental expectations • Bond prices • Fixed risk premia via constant • Present model • Incorporates transaction volumes • Money supply

Full model to 2009 Q4 – key findings • Changes in relationships • Bond relationship turns negative • Dividend yield relationship insignificant • Serial correlation appears • Why? • Chasing the yield • Outward movement of yields following financial crisis Source :DTZ Research
Full model to 2009 Q4 – solutions • Need to incorporate other variables into this analysis • In particular risk measures and time varying premia Source :DTZ Research

Conclusions London (City) • Structural break found in yield relationships using old methodology • Previous relationships have changed in the current environment • More sophisticated modelling of risk needed to take into account more volatile risk markets London (West End) Madrid Paris Sydney Frankfurt New York Shanghai Tokyo Source: DTZ Research
