Are the effects of monetary policy on output asymmetric in Pakistan?

This research mainly investigates whether the response of output to monetary policy actions is symmetric or not We test all the three main forms of asymmetries in the impact of monetary policy discussed in the literature so far. Also, we make some hybrid cases to go further in the detail of the tested asymmetries. While mainly following the methodology given by Cover (1992), we make some necessary variations to the procedure. We find evidence in the favor of asymmetry in the effects of monetary policy actions on output. Our results indicate that monetary policy actions seem ineffective in periods of high growth while having strong effects on output during low growth periods. Further, output responds strongly to tight monetary policy actions when the economy is in low growth phase. We also find some support for the argument that negative money supply changes affect output whereas positive changes do not. The findings also suggest that output responds only to small monetary policy shocks and big shocks do not significantly explain the variations in the transitory component of output The results of hybrid case give further insight that output strongly responds to small negative monetary policy shocks. Wald test rejects the hypothesis of symmetry in the favor of asymmetry in the response of output to monetary policy actions in all the cases. (C) 2013 Elsevier B.V. All rights reserved.
