This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several tests based on a t-ratio have been proposed in the literature to decide the order of integration of a time series allowing for a structural break. However, another approach based on testing a joint hypothesis of unit root and the irrelevance of some nuisance parameters is also feasible. This paper proposes new unit root tests consistent with the presence of a structural break applying this second perspective. Our approach deals both with the case where the break is not allowed under the null hypothesis, and where it is allowed. Simulations investigate the performance of this proposal compared to the existing tests and show important gains in terms of power.

This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop extensions of the Dickey-Fuller F-statistics for the joint null hypothesis of a unit root that allows for a break in the innovation variance. Our statistics are based on the modified generalized least squares (GLS) strategy outlined in Kim, Leybourne and Newbold [Journal of Econometrics (2002) Vol. 109, pp. 365387] that requires estimation of the break-date and corresponding pre-break and post-break variances. We derive the asymptotic distribution of the new F-statistics, tabulate their finite sample and asymptotic critical values, and present finite sample simulation evidence regarding their size and power.

This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we provide tests for the unit-root hypothesis against the occurrence of an unspecified number of breaks which may be larger than 2 but smaller than the maximum number of breaks allowed, m, in univariate time-series models. The advocated procedure is considerably less computationally intensive than those widely used in the literature. We provide critical values for the test and examine its small sample properties through Monte Carlo experiments.

Available in PDF, EPUB and Kindle. Book excerpt: In this paper, we review the recent econometric methods related to unit root tests. The central idea is the interaction between structural breaks and unit roots. We consider the standard Dickey-Fuller test and its modifications that allow under the alternative hypothesis one or multiple structural breaks. The break dates are endogenous and the number of breaks may be unknown. We investigate the size and power of these tests. Thus we consider the problem of estimating the number of structural breaks and the problem of estimating the break dates. A second type of test is reviewed, the LM unit root tests that allow under the null and the alternative hypothesis one or two unknown breaks. We also discuss the tests of structural breaks built for a stationary variables. We distinguish two types of tests: tests for a single break and tests for multiple breaks.

Download or read book Seasonal Unit Root Tests Under Structural Breaks written by Uwe Hassler and published by . This book was released on 2004 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, several seasonal unit root tests are analysed in the context of structural breaks at known time and a new break corrected test is suggested. We show that the widely used HEGY test, as well as an LM variant thereof, are asymptotically robust to seasonal mean shifts of finite magnitude. In finite samples, however, experiments reveal that such tests suffer from severe size distortions and power reductions when breaks are present. Hence, a new break corrected LM test is proposed to overcome this problem. Importantly, the correction for seasonal mean shifts bears no consequence on the limiting distributions, thereby maintaining the legitimacy of canonical critical values. Moreover, although this test assumes a breakpoint a priori, it is robust in terms of misspecification of the time of the break. This asymptotic property is well reproduced in finite samples. Based on a Monte-Carlo study, our new test is compared with other procedures suggested in the literature and shown to hold superior finite sample properties.

Available in PDF, EPUB and Kindle. Book excerpt: Testing for a Unit Root is now an essential part of time series analysis but the literature on the topic is so large that knowing where to start is difficult even for the specialist. This book provides a way into the techniques of unit root testing, explaining the pitfalls and nonstandard cases, using practical examples and simulation analysis.

Available in PDF, EPUB and Kindle. Book excerpt: 'Natural Resources: Neither Course nor Destiny' brings together a variety of analytical perspectives, ranging from econometric analyses of economic growth to historical studies of successful development experiences in countries with abundant natural resources. The evidence suggests that natural resources are neither a curse nor destiny. Natural resources can actually spur economic development when combined with the accumulation of knowledge for economic innovation. Furthermore, natural resource abundance need not be the only determinant of the structure of trade in developing countries. In fact, the accumulation of knowledge, infrastructure, and the quality of governance all seem to determine not only what countries produce and export, but also how firms and workers produce any good.
