Abstract

This paper is an attempt to gauge the relationship between the long run paths of consumer price index and wholesale price index of Pakistan. For the empirical analysis the Johansen co-integration technique has been applied on monthly data (1978 to 2010) of WPI and CPI. This paper found that both the indices are co-integrated in the long run. Thus the deviations in movements of WPI and CPI in the short run are transitory and both the indices will converge to their coherent path in the long run. Therefore, inflation computed from CPI can be used as official measure of inflation without worrying for short run ovements of WPI.
