Understanding the monetary policy transmission mechanism is pivotal for the design of an effective monetary policy. In this regard, the coexistence of interest rate and cost channel of monetary policy has raised important implications for the conduct of monetary policy. This article estimates a New Keynesian model to quantify the strength of interest rate and cost channel by estimating retail rate stickiness and share of firms considering interest rate in their marginal cost function. It examines the extent of interest rate pass-through and cost channel for exogenous monetary policy shock and endogenous movement in official rate arising due to other financial, nominal, and real shocks in the economy. The trade-off between the degree of pass-through and cost channel of monetary policy has also been examined. The minimum distance estimation of the Dynamic Stochastic General Equilibrium (DSGE) model has confirmed that the degree and nature of interest rate pass-through depend on the nature of shock hitting the economy and the cost channel exists only for monetary and financial shocks. A weak trade-off also exists between the degree of pass-through and cost channel of monetary policy. The study recommends that coordination between central banks and financial and non-financial firms is essential for effective stabilization through monetary policy.
