Identifying long run supply curve of India

Identifications of a vertical then a horizontal supply curve are successively imposed on Indian time series inflation and industrial output growth data in a two-equation Structural Vector Autoregression (SVAR) model. The results provide an indirect test of the identifications. A high elasticity of long run supply cannot be ruled out, because supply shocks have a large impact on inflation and demand has a large and persistent effect on output levels. But supply is subject to frequent shocks. Estimated structural shocks capture historical recessions and turning points well. Pro-cyclical policy induced demand shocks aggravated negative supply shocks or failed to take full advantage of positive supply side developments

Analysing Core Inflation in India: A Structural VAR Approach

Effective inflation targeting requires careful selection of the inflation target. It is necessary to leave out noisy elements, which monetary policy cannot control, but this exclusion should not be done in an ad hoc way. Rather core inflation should be determined from the structure of the economy. This paper estimates core inflation for India using Structural Vector Autoregression (SVAR). This method is based on both theory and the structure of the economy. Monthly data for wholesale price index (WPI) and index of industrial production (IIP) has been used, covering a long time span from January 1971 to July 2004. We analyze the impulse responses of inflation and output, test for several time series properties of core inflation and carry out a number of Granger causality tests between headline inflation, core inflation, output and a monetary aggregate
