This paper examines whether there is an asymmetry in the effects of positive versus negative and small versus big money supply shocks, and whether the effects of the shocks on output and prices vary over the business cycles in the case of Turkey. Negative shocks to money are found to have...

Using a dynamic panel data approach, we estimate the impact of the political and institutional factors on inflation. Estimation results show that a lower degree of political instability generates lower inflation only for developed and low-inflation countries. However, when political freedom is...

Recent developments in time series analysis allow proper modelling of nonlinearities in economic and financial variables. A growing body of research was dedicated to investigation of potential nonlinearities in conditional mean of many economic and financial variables, mainly concentrating in...

In this article we re-examine efficiency of the Australia's and New Zealand's stock markets, extending recent work of Narayan (2005). For this purpose we apply the nonlinear unit root test procedure recently developed by Kapetanios et al. (2003). The nonlinear unit root tests reject the null...

In this article, we investigate the effects of inflation variability on short-term interest rates within a nonlinear smooth transition regression framework. The test results suggest that only the conditional mean of the inflation is a nonlinear process whereas the conditional variance is time...
