Cyclical and Structural Components to Yield Movements: The Case of Central London Offices
Michael White, Keith Lown, and Ignas Gostautas
London and Real Estate
• Approximately 22% of UK GDP [ONS]
• One of three largest global financial centres• Europe’s second largest city: c.8.6 million…and growing• Europe’s biggest real estate market• UK lacks second city of critical mass

Central London Core Office Markets in 2015
• Historic low yields in every London sub sector• Inflows of investment capital at an all time high• Occupational demand at a new high• London’s safe status haven reinforced as never before• Foreign investment accounted for 66% of investment turnover [CBRE]

Initial Yields: 1981 – 2013
London – Cycle or Trend?
• Is London becoming more different or are current yield reductions simply pointing to a cyclical turning point just ahead?
• Is the yield gap between London and regional cities persistent or temporary?
• Have flight-to-safety motives and increasing international investment temporarily distorted yields in London markets?
Yield Drivers
• Logically, yields are a function of the required rate of return for property and expected rental growth.
• Yields in cities may reflect local as well as national influences (Sivitanidou and Sivitanides, 1999)
• Local market characteristics may be more important than national inflation rates and stock market performance
• Local economic structures and supply differences can create individual city rent cycles (Orr and Jones, 2003)
• Such differences may imply local markets having different risk premiums (Gunnelin et al 2004)
Other Assets
• While the above discussion identifies endogenous yield drives, exogenous factors such as the performance and expected performance of other assets (Barras, 1994; Hendershott and MacGregor, 2005)
• In the models below we consider stocks and government debt as the main alternative investment classes
• The models estimated here usefully extend previous research by Dunse et al (2008)
Research Method
• In estimation the initial yield is written as a function of the gross redemption yield on long dated gilts, the yield on the FTSE all share index, and rental value growth.
• Following Hendershott and MacGregor (2005) we incorporate deviations from equilibrium for rent and the stock market yield variables. Mean reversion is captured by using a two year moving average of the real rent or stock market dividend from trend.
Model
• A long run reduced form equation for office yields is:
• If the variables in the long run model are cointegrated, there is a stationary error and then a short run yield adjustment model can be set up in an error correction form:

City Level Panel Data: 1981 - 2013
Fixed Effects Panel Model – Long Run Equation
Variables have expected signs on rental value growth, rental deviation, gilt yield, and dividend yield although the dividend deviation is not significant at the 5% level.
Fixed effects seem to vary across cities.
This is confirmed above as we reject the null that the cross section effects are redundant.

In this model the error correction term is correctly signed and statistically significant. Of the other variables only the deviation terms are significant.

Results and Conclusion
• These results indicate that initial yields respond to rents, gilts, and dividends as expected
• Some differences exist between London and other cities in relation to the sensitivity of initial yields to dividend yields
• The current gap between London and regional markets – will it persist?
