Monetary Policy Dilemmas at the Current Juncture

Monetary policies in advanced economies and emerging markets face quite different challenges at the current juncture. In the advanced countries, current dilemmas derive from the normalisation of unconventional monetary policies. The short-term dilemma is to determine when to start exiting extraordinary policies and selecting appropriate tools, as conventional tools may not be very relevant during this phase. The medium- to long-term challenges relate to the sequencing, pace and mechanics of normalisation. Monetary policy in emerging markets needs to cope with the familiar dilemmas of fiscal dominance, the growth-inflation trade-off and the "impossible trinity." With fiscal parameters in control, and food and commodity prices subdued, the chief dilemma currently confronting emerging markets involves a trade-off between targeting divergent domestic and external cycles. Although they are now better placed to absorb a sudden stop, the impact is likely to be differential, with those with weaker macroeconomic parameters suffering greater pain.

Dynamic Stochastic General Equilibrium Modelling

In recent years Dynamic Stochastic General Equilibrium models have come to play an increasing role in central banks, as an aid in the formulation of monetary policy (and increasingly after the global crisis, for maintaining financial stability). DSGE models, it is claimed, are less a-theoretic than other widely used models such as VAR, or dynamic factor models. As the models are "structural," they are supposed to be immune to the Lucas Critique, and thus can be "taken to the data" in a meaningful way. However, a major feature of these models is that their theoretical underpinnings lie in what has now come to be called as the New Consensus Macroeconomics. Using the prototype real business cycle model as an illustration, this paper brings out the econometric structure underpinning such models. A detailed analytical critique is also presented together with some promising leads for future research.
