The research
• Preliminary to more detailed & refined analysis– the distribution of investment stock in relation to economic activity– long run allocations vs market performance & fundamentals– the drivers of short-run investment flows
• Illuminating issues in– neo-classical vs uneven vs institutional vs cultural spatial theories– long run economic growth vs property performance– causation & rationality in investment allocations
• At this stage– standard proxy indicators of market dynamics applied to long run– regional scale of analysis recognising aggregation problems– to utilise full set of indicators, test methods, show the big picture
Literature
• A bit of a blind spot– theories of spatial development mostly lack investment property– property market analysis mostly on short run dynamics
• Regional economic development & investment property– skewed distributions of investment stock (Key & Law, 2004)– taken as evidence of cultural bias (Henneberry & Roberts, 2008)– alternative institutional / expectations explanations (Ball, 2001)– … lacking a comprehensive view of sectors, processes
• Property performance, investment flow, local economies– US MSA market performance & economics (Piazzi et al, 2008;
Liang & McIntosh 1998): weak links from long run economics to returns
– US MSA returns & investment flows (Fisher et al, 2009): no consistent forward / backward linkage from returns to flows
Data & methods
• All the usual UK indicators– performance (IPD), portfolios & investment flow (IPD), demand
(ONS), stock (VOA), development (DTI) indicators
– limitations of demand / supply proxies, IPD partial coverage
• 11 GB regions, annual data 1981-2009, three main sectors
• Analysis: regional variation within sectors– Stylised facts on regional property performance
– Long run shifts: portfolios, investment flow vs market performance, market demand-supply fundamentals
– Short-run dynamics: response of investment flow to relative performance, demand & supply
• Basic cross-section & time series correlation / regression
• More rigorous methods – Grainger, VAR – to follow

• Large variation: terminal
value of £100 invested in
1980 from £623 to
£2,730
• Consistent pecking order
industrial-retail-office for
sectors & within regions
• Differentials in return
primarily the product of
unpriced variation in
rental value growth
• Regional returns reflect
risk only across retail
regions
Source: IPD
Findings 1 – drivers of long run performance
• Across regions negative relationship between– demand growth and rental value growth
– demand growth and total return
– long run supply accommodates variation in economic growth
– yield pricing does not anticipate rental or economic performance
– consistent with Liang & McIntosh (1998)
• But supply response does not explain rental variation– supply response measured by beta of construction volumes wrt
demand, total construction per unit demand, total construction per unit demand growth
• Weak level of explanation in supply factors may be due to low number of cross-sectional observations, problems with proxies, wrong level of aggregation

Findings 2 – long run portfolio allocations
• All analysis on weights, relative performance within sectors
• Changes in weights:– dominant effect in all sectors fall in London weights– balancing gains southern offices, northern retail, general industrial– weight shifts mainly produced by allocations of capital spending
• Explaining changes in weights & investment allocation– nothing to do with long run returns or rental value growth– linked to rates of demand growth only in office sector– positively link to “oversupply” retail & industrial, negative in offices– no consistent regional preference across sectors
• southern “bias” against relative performance only in office• no over-arching regional picture or weight driver

Findings 3 – investment dynamics
• Tracking year by year within sectors– shifts in region weights produced by investment allocation– relative property performance of the region– relative economic growth & changes in new supply
• To identify– direction & persistence in application of investment policy– sensitivity of investment to market cycle, economic fundamentals– regional typology of investment behaviour– leads / lags of capital flow, values & returns
• Results– variation in strength, persistence, sensitivity of money flows– no consistent patterns across sectors / regions– no immediately obvious classification of policy “types”

Discussion
• Basic facts– long run property performance independent of market fundamentals– long run shifts in allocation dominated by falling London weight– investment flows: mix of fixed preference, cyclicals, nothing obvious– no over-arching north-south or other regional differentiation– weak explanation of direction & changes in investment policy
• Reservations & further work– limited by regional scale, basic methodology, broad proxies– more powerful methods: leads/lags, Grainger Causality, VAR– urban level (losing some indicators, lumpy flows may add noise)
Implications
• Why the low level of explanation– regional scale means small number of obs, aggregation problems in
terms of spatial scale, consistency problems with proxy measures– analysis is ex-post with full information, decisions are ex-ante with
uncertain information– investment policy may be set by unobserved variables (benchmark
hugging, deal flow, exit risk capital raising)
• Paradigms of spatial adjustment– lack of consistent patterns runs against over-arching explanations– if cultural why not all sectors; if positivist why South East offices; if
cumulative causation why northern retails– next steps to generate testable hypotheses from competing
paradigms, and run with varying levels of aggregation
