The data generation process underlying regional house prices in the UK
is investigated using new statistical tests. It is found that causal
flows tend to be northwards: the South East (rather than Greater Londo
n) acts as an exogenous price determinator of the other regions in the
south; the Midland regions have a great influence on prices in the no
rth and flows through the East Midlands are characterised by bi-direct
ional causality. These results are largely independent of assumptions
made about the data generation process (and tests of these assumptions
have low power in any case). There are also similarities between this
causality and migration patterns, particularly in the south of Englan
d.
