Abstract

Paper ini berupaya menganalisa implikasi perilaku bank dalam menentukan portofolio terhadap tingkat efektivitas kebijakan moneter. Dengan kerangka analisa comparative static, paper ini mengetengahkan model industri perbankan yang bersifat monopolis dimana pemilik bank memaksimalkan profit dengan kendala tertentu baik yang berasal dari kesanggupan modal maupun kendala akibat regulasi.

Kalibrasi model pada kondisi optimal, mengindikasikan bahwa penurunan fungsi disintermediasi bank yang didominasi oleh faktor asymmetric information, akan berakibat pada menurunnya efektifitas kebijakan moneter.

Kesimpulan ini berimplikasi pada (i) perlunya Biro Kredit dan rating agencies untuk menyempurnakan informasi, (ii) perlunya investasi yang lebih besar oleh perbankan atas kapasitas riset dan sistem monitoring, (iii) perlunya mempertimbangkan skema garansi kredit, (iv) perlunya koordinasi yang lebih baik antara kebijakan mikro dan makro demi kestabilan makro yang akan meningkatkan keyakinan publik dan terakhir, (v) perlunya mempromosikan perkembangan lembaga keuangan non-bank, untuk mengurangi ketergantungan pembiayaan atas lembaga perbankan.
