| Summary: | Asymmetric effect, in the context of monetary policy, refers to a situation in which
the effects of a given policy are not constant but vary depending on the circumstances.
By employing a relatively popular technique of non-linear modelling - for instance,
Hamilton's Markov-switching model - this study empirically analyses if real output
asymmetrically responds to monetary policy shocks in four ASEAN economies:
Indonesia, Malaysia, the Philippines and Thailand. Typically, the asymmetries in
discussion are pertaining to, (i) the policy action and, (ii) the phase of the business
cycle. Quarterly data spanning the period from 1978: 1 for Indonesia; 1974:l for
Malaysia; 1977:l for the Philippines and Thailand; to 2003:4 are being utilised in this
study.
Several important observations can be made based on this study. First, this study
provides evidence that a tight monetary policy has a larger absolute impact than an
easy policy. For instance, by incorporating a time-varying inflation parameter in the
model, both the money supply shocks and interest rate shocks in all economies under study are found to have asymmetric effects on real output, in which the effects of an
easy policy mitigate while the effects of a tight policy increase, with higher inflation
rates. Furthermore, the inverted L-shaped aggregate supply curve and negative-sloped
equilibrium locus is supported in the case of Indonesia, the Philippines and Thailand.
This evidence implies that an easy policy has a favourable impact, no impact and a
harmful impact on output during the low, medium and high inflation regimes
respectively in these economies. The fact of asymmetry is particularly important in
the Asian context in their discussion and formulation for a monetary union. It implies
that monetary authorities must take into account not only the fact that these
economies do not react symmetrically in response to the policy action but also the
behaviour of the inflation process. In other words, the evidence of high inflation rates
for some of the developing economies may contribute to increased asymmetries in
this context.
Second, the results do support the argument that effects of monetary policy vary
depending on the phase of the business cycle. More precisely, monetary policy effects
are found to be larger during recessionary periods for all economies under study. This
finding therefore suggests the important role that credit market imperfections have on
a firm's investment behaviour, which in turn points to the financial accelerator as a
relevant mechanism underlying the observed asymmetry. An important lesson based
on this study is that the macroeconomic stability will be in dire peril if financial
systems of these economies are not managed prudently. Policies thus may be designed
to reduce the financial sector's vulnerability to a crisis by encouraging appropriate
and disciplined financial intermediary practices. |
