where r is the return on home and EM (h, f) assets, R is the parameter of relative risk aversion,
2 h
and
2 f
are the respective variances of returns, and
hf
is their covariance. Thus the demand for emerging market assets depends in part on ‘fundamentals’ (
f
r and
2 f
) but also on home - or other foreign – market conditions such as risk aversion and home volatility (R,
h
r and
2 h
) and the correlation between different markets (
hf
) which underpins ‘contagion’. All of which vary strongly and rapidly causing ‘external shocks’. The empirical evidence indicates that the latter is at least as important as the former; especially during crises (when both risk aversion and market covariance rise).
