My primary area of interest is macroeconomics. In macroeconomics, I am interested in monetary economics. I do research on the formulation and implications of optimal monetary policy based on New Keynesian DSGE model. I am also interested to study the economic implications of central bank’s independence on monetary policy formulation. Beside this, I am interested in economics of growth, open economy macroeconomics and development economics too.

The Dynamic Stochastic General Equilibrium (DSGE) models is the workhorse of modern macroeconomic analysis. DSGE models have a strong microfoundation. Here, the quantitative implications of the models play a crucial role in determining model’s suitability and policy implications. The suitability of DSGE models is judged on the basis of comparing moments of actual data with the same obtained from the model through calibration and/or simulation. Here lies the importance of econometrics in modern macroeconomic analysis. Econometrics and macroeconomics are intrinsically related to each other now a days. As a result, my secondary field of expertise and area of interest is automatically applied econometrics. In applied econometrics, I work on time series analysis, unobserved component modelling and forecasting.
