This study reviews the empirical literature on the integration properties of energy
consumption and production. The survey begins with a discussion of the implications of …

This paper proposes new unit root tests that are more powerful when the error term follows a
non-normal distribution. The gain in power is achieved by utilizing the additional moment …

The nonlinear unit root test of Kapetanios, Shin, and Snell (2003)(KSS) has attracted much
recent attention. However, the KSS test relies on the ordinary least squares (OLS) estimator …

This paper considers the test of a unit root in transitional autoregressive models. In
particular, we develop the asymptotic theory of the inf-t test for the null hypothesis of a unit …

Real interest rate is a crucial variable that determines the consumption, investment and
saving behavior of individuals and thereby acts as a key policy tool that the central banks …

While there is good reason to expect crude oil production to be non-linear, previous studies
that have examined the stochastic properties of crude oil production have assumed that …

In this paper we reexamine the current account sustainability under assumptions of smooth
break and nonlinearity for nine European countries. We test for the null hypothesis of a unit …

This article develops a novel test for a unit root in general transitional autoregressive
models, which is based on the infimum of t‐ratios for the coefficient of a parametrized …

We apply the Pesaran (2007) pair-wise approach of convergence to the per capita outputs of
195 European regions for the period 1980–2006. Pesaran's approach is based on the …

This paper examines the sustainability of the current account deficit in eighteen Latin
American countries through the analysis of the stationarity properties of the current account …
