ABSTRAK

Kemiinculan ‘hipotesis jangkaan rasional’ pada tahun 1970-an telah me.i.cwjudkan perdebatan ke atas keberkesanan polisi permintaan agregat dalam mempengaruhi aktiuiti ekonomi benar. Seiring dengan ini, Kritik Lucas (Lucas, 1976) , yang didasari oleh hipotesis jangkaan rasional telah mempersoalkan keberkesanan peraturan polisi yang sering diamalkan di dalam perlaksanaun polisi monetari. Komentari ini mengimbas landasan utamu Kritik Liicas dan kajian empirikal yang dilaksanakan oleh Habibullah, Azali dan Bahartirnshuh (2001) (ringkasnya H A B ) ke atas kritik berkenaan di dalam persekitaran ekonomi Malaysia. Landasan bagi Krit ik Liicas dijelaskan dengan lebih terperinci melaliri pembentukan model ekonomi yang mengambil kira tingkah laku agen ekonomi yang bercirikan jangkaizn rasional. Ujian empirik ringkas menunjukkan bahawa penolakan Kritik Lucas seperti yang diutarakan oleh H A B perlu diperincikan lagi sebelum ianya bdeh diterima umum.

ABSTRACT

The advent of ’rational expectation hypothesis’ ( R E H ) in 1970’s sparked in- tense debate on the ej-ectiveness of discretionary uggregate demand policies in influencing real economic actiuities. In line 7uii h this, the Lucas Critique (Lucas, 1976), that embodies the REH, questions the efjcectiueness of policy rule thatpequent ly adopted in the set u p of monetra ry policy. This commen- t a y reuisited the foundations of Lucas Critique and empirical studies re- ported by Habibullah, Azali dan Baharumshah (2001) (in short, H A B ) on the ualidity of the critique within the Malaysian economy. The Lucas Critique is explained in greater detail based on an economic model that incorporates the behauioiirs of economic agents that f o rm their expectation rationally. Brief
