This study assess the nonlinear behavior of U.K. construction and real estate indices. Standard unit root tests show that both time series are I(1) processes. However, the empirical results show that the returns series for both indices deviate from the null hypothesis of white noise. Moreover,...

In a recent paper, Razzak (2001) finds some evidence of two types of asymmetry,steepness and deepness, in international business cycle data, using the nonparametric test of Randles et al. (1980). In this paper, we test for three types of asymmetry: steepness, deepness and sharpness, using the...

This paper examines conditional and unconditional asymmetries in the Nelson and Plosser dataset by using two tests recently proposed by Jushan Bai and Serena Ng. In line with previous research, the results show that asymmetry is not a proper characterization of most macroeconomic series,...

Since time reversibility (TR) is a necessary condition for an independent and identically distributed (iid) sequence, several tests for TR have been suggested to be applied as tests for model misspecification. In this paper, we compare the power of two well known TR tests against two situations:...

We propose a new testing procedure to determine the rank of cointegration. This new method is based on the nonparametric resampling procedure, so-called Residual-Based Block Bootstrap (RBB), which is developed by Paparoditis and Politis (2003) in the context of unit root testing. Through Monte...
