Recent research work has shown that inflation rate is asymmetric and it is also well known that asymmetry is a non-linear phenomenon. In order to better understand this non-linearity in inflation of Pakistan, we investigate the possible presence of Smooth Transition Autoregressive (STAR)...

In this paper we estimate the output gaps of the AGCC countries using four different methods that are: the linear trend model, Hodrick-Prescott filter, Band-Pass filter and the unobserved components model. To perform meaningful comparisons, we differentiate between the overall and non-oil output...
