Nonlinear behavior of the Chinese SSEC index with a unit root: Evidence from threshold unit root tests

Testing Fiscal Reaction Function in Iran: An Application of Nonlinear Dickey-Fuller (NDF) Test

Abstract T his paper is to convince the usage of the nonlinear unit root tests when dealing with a nonlinear model. To do so, the stationary test for variables in a model titles “Fiscal Reaction Function in Iran” has been applied according to both the ordinary and the Nonlinear Dickey-Fuller (NDF) tests. Results show that while variables under investigation are stationary ...

A Study of Testing Mean Reversion in the Inflation Rate of Iran’s Provinces: New Evidence Using Quantile Unit Root Test

T his paper is to examine the mean reverting properties of inflation rates for Iran’s 25 provinces over the period from 1990:4 to 2017:7. To the end, we use various conventional univariate linear and non-linear unit root tests, as well as quantile unit root test by Koenker and Xiao (2004). Results of conventional unit root tests indicate that the null hypothesis of the unit root test...

Purchasing Power Parity Hypothesis In OIC Countries: Evidence From Panel Unit Root Tests With Heterogeneous Structural Breaks

Convergence of Real Per Capita GDP within East Asian and Middle East Countries: Panel Unit Root Evidence

This paper examines convergence of real GDP per capita in the selected East Asian countries and this relationship with selected Middle East countries during the period 1950-2009. The reason behind this refers to the fact that East Asia countries (including China, Hong Kong, Singapore, Malaysia, Indonesia, Thailand, Japan and South Korea) have been involved in achieving success arising from regi...

The Effects of Oil Price Movement on Nigerian Macroeconomic Variables: Evidence from Linear near and Nonlinear ARDL Modelling

T he study seeks to investigate both linear and nonlinear effects of oil price movement on critical macroeconomic variables (output, price and exchange rate) in Nigeria using ARDL modeling approach. Previous studies substantially relied on linear methods using VAR approach to unravel this links without a clear conclusion. In an attempt to seek better results in this study, we employ both l...
