In this paper, we propose a nonlinear cointegration test for heterogeneous panels where the alternative hypothesis is an exponential smooth transition (ESTAR) model. We apply our tests for investigating cointegration relationship between energy consumption and economic growth for the G7...

In this study, we propose a new unit root test procedure that allows for both gradual structural break and asymmetric nonlinear adjustment towards the equilibrium level. Small-sample properties of the new test are examined through Monte-Carlo simulations. The simulation results suggest that the...

In this paper we have estimated the monetary reaction function of the Central Bank of Republic of Turkey. The originality of the paper is that we have used smooth transition functions (STR) that allow for proper modelling of nonlinearities and asymmetries in the relationship between variables...

In this study, a bi-variate Generalized Autoregressive Conditional Heteroscedasticty model is used in order to investigate the Granger causality relationships between output growth, inflation rate and their uncertainties. Our test results show that the existence of Granger-causality is observed...

In this paper, we have investigated the effects of Asia 97 crisis on Malaysian stock exchange market by using a nonlinear approach which gives a detailed analysis with respect to linear counterparts. Specifically, we are using generalized impulse response function (GIRF) in order to see the...

In this paper, we examine causal relationships among inflation rate, output growth rate, inflation uncertainty and output uncertainty for ten Central and Eastern European transition countries. For this purpose, we estimate a bivariate GARCH model that includes output growth and inflation rates...

This study investigates whether the term structure of interest rates contains useful information about future real economic activity and inflation in Turkey during the 1991:7-2004:3 periods. In order to analyze these relationships, we have employed the Generalized Impulse Response (GIRF)...

In this study, we examine the relationship between foreign direct investment and terrorist incidents that took place in Turkey for the period from 1991:12 to 2003:12. This research contributes to the literature by checking for a possible non-linear relationship between terrorism and foreign...

The aim of this study is to search for a better optimization algorithm in applying unit root tests that inherit nonlinear models in the testing process. The algorithms analyzed include Broyden, Fletcher, Goldfarb and Shanno (BFGS), Gauss-Jordan, Simplex, Genetic, and Extensive Grid-Search. The...

This study proposes a flexible unit root test that detects sharp and smooth breaks simultaneously. Most unit root tests are not general enough to capture different dynamics, such as smooth structural breaks, sharp structural breaks, state-dependent nonlinearity or a mixture of them. Therefore,...
