In this paper we examine three types of nonlinearities, i.e., nonlinearity stemming from structural breaks, sign nonlinearity and size nonlinearity, for ten European countries and their importance to current account sustainability. For this purpose, we apply a battery of linear and nonlinear...

Whether or not a current account deficit is sustainable has important implications for policy. If the current account deficit of a nation is sustainable, then it implies that the government should have no incentive to default on its international debt. In this article, we examine whether or not...

This paper examines the nonstationary and nonlinear features of the non-renewable resource markets: the crude oil (US West Texas Intermediate and UK Brent), bituminous coal and natural gas markets. In particular, we achieve this goal by using the Markov switching unit root regression. This...

Chen (2011) [Are current account deficits really sustainable in the G-7 countries? Japan and the World Economy, 23(3), 190–201.] examines whether or not the current account deficits of the US can be characterized by a unit root process with regime switching (MS-ADF). In this paper, we find...
