Available in PDF, EPUB and Kindle. Book excerpt: This work builds a flexible model accommodating nonlinear dynamics around a trend function with multiple (up to) gradual shifts. Such a model is suitable for capturing the behavior of many post World War II economic time-series subject to the onset of external causes such as oil crises, financial crises, technology changes and regulatory changes. Deriving unit root tests in this nonlinear model is of particular interest. In fact, the options of a general trend specification and nonlinear dynamics are critical to remedy unit root tests not being biased toward a non-rejection of a unit root hypothesis and prevents the first-differences of a series from being used too often. An asymptotic theory for the unit root tests is also established. The unit root tests are applied to G7 industrial production series, and evidence in favor of nonlinear trend 'stationary' models is found in a majority of the cases. The merits of the new model are further demonstrated in an estimation exercise for the US industrial production series, and evidence of four gradual shifts in the trend, different growth patterns for different periods, and business cycle asymmetries is found.

Download or read book Recent Advances in Estimating Nonlinear Models written by Jun Ma and published by Springer Science & Business Media. This book was released on 2013-09-24 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nonlinear models have been used extensively in the areas of economics and finance. Recent literature on the topic has shown that a large number of series exhibit nonlinear dynamics as opposed to the alternative--linear dynamics. Incorporating these concepts involves deriving and estimating nonlinear time series models, and these have typically taken the form of Threshold Autoregression (TAR) models, Exponential Smooth Transition (ESTAR) models, and Markov Switching (MS) models, among several others. This edited volume provides a timely overview of nonlinear estimation techniques, offering new methods and insights into nonlinear time series analysis. It features cutting-edge research from leading academics in economics, finance, and business management, and will focus on such topics as Zero-Information-Limit-Conditions, using Markov Switching Models to analyze economics series, and how best to distinguish between competing nonlinear models. Principles and techniques in this book will appeal to econometricians, finance professors teaching quantitative finance, researchers, and graduate students interested in learning how to apply advances in nonlinear time series modeling to solve complex problems in economics and finance.

Download or read book Structural Change and Moderating Growth in the People s Republic of China written by Asian Development Bank and published by Asian Development Bank. This book was released on 2016-12-01 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The People's Republic of China (PRC) is currently undergoing a number of structural and cyclical changes, which have wide-ranging implications for economic activity in the PRC, the rest of developing Asia, and the world. This report assesses the effects of these changes on the rest of the region and the world, looking closely at various channels of transmission including commodity prices, trade, and production. The continued moderation of growth in the PRC could knock off a third of a percentage point a year in growth for the rest of developing Asia over the next 2 years. Changes in PRC economic activity significantly affect commodity prices, but the estimated impact varies by commodity. This report discusses how developing Asia's policy-makers can respond to the challenges and opportunities presented by these changes.
Download or read book Testing for Unit Roots in Panel Time Series Models with Multiple Level Breaks written by Joakim Westerlund and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper proposes two new unit root tests that are appropriate in the presence of an unknown number of structural breaks in the level of the data. One is based on a single time series and the other is based on a panel of multiple series. For the estimation of the number of breaks and their locations, a simple procedure based on outlier detection is proposed. The limiting distributions of the tests are derived and evaluated in small samples using simulation experiments. The implementation of the tests is illustrated using as an example purchasing power parity.

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.
Download or read book Interaction Between Unit Roots and Structural Breaks written by Charbel Bassil and published by . This book was released on 2013 with total page pages. 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 The Dynamics of Growth in Emerging Economies written by Arzu Akkoyunlu Wigley and published by Routledge. This book was released on 2018-12-19 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: How can Turkey increase its medium- and long-term growth potential? Despite episodes of fast growth, this has become a vital question for the Turkish economy, in order to avoid being stuck in a middle-income trap. There has been an increase in the number of studies presenting growth in Turkey and quantifying the sources of economic growth, however, due to the difference in the main underlying assumptions and the time period covered in these studies, the results differ. The second strand of literature on growth in Turkey identifies the relative underperformance of the Turkish economy by developing models with microeconomic foundations. Given the fact that there are a large number of studies investigating the macro dynamics of growth in Turkey, the book’s unique focus on the "neglected" issues in growth discussions closes the gap in the existing literature. It addresses the micro, macro, regional, and gender aspects, the environment–energy–growth nexus, as well as the microeconomic dynamics of growth. It also analyses the other significant determinants of long run growth in Turkey such as import dependency and saving-investment decision. The authors provide a macro overview of all of the precluded subjects in order to evaluate them in relation to one other, as well as to derive policy conclusions from them. This book primarily targets academics as well as graduate and undergraduate social sciences and humanities students both in Turkey and other countries. It is also a must read for researchers and policy makers not only in Turkey but also in other developing economies and is of interest to specialists of non-governmental and non-profit organizations.
Download or read book New Facets of Economic Complexity in Modern Financial Markets written by Catherine Kyrtsou and published by Routledge. This book was released on 2020-06-04 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book is motivated by the disruptions introduced by the financial crisis and the many attempts that have followed to propose new ideas and remedies. Assembling contributions by authors from a variety of backgrounds, this collection illustrates the potentials resulting from the marriage of financial economics, complexity theory and an out-of-equilibrium view of the economic world. Challenging the traditional hypotheses that lie behind financial market functioning, new evidence is provided about the hidden factors fuelling bubbles, the impact of agents’ heterogeneity, the importance of endogeneity in the information transmission mechanism, the dynamics of herding, the sources of volatility, the portfolio optimization techniques, the financial innovation and the trend identification in a nonlinear time-series framework. Presenting the advances made in financial market analysis, and putting emphasis on nonlinear dynamics, this book suggests interdisciplinary methodologies for the study of well-known stylised facts and financial abnormalities. This book was originally published as a special issue of The European Journal of Finance.

Download or read book Econometric Modelling with Time Series written by Vance Martin and published by Cambridge University Press. This book was released on 2012-12-28 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a general framework for specifying, estimating and testing time series econometric models. Special emphasis is given to estimation by maximum likelihood, but other methods are also discussed, including quasi-maximum likelihood estimation, generalised method of moments estimation, nonparametric estimation and estimation by simulation. An important advantage of adopting the principle of maximum likelihood as the unifying framework for the book is that many of the estimators and test statistics proposed in econometrics can be derived within a likelihood framework, thereby providing a coherent vehicle for understanding their properties and interrelationships. In contrast to many existing econometric textbooks, which deal mainly with the theoretical properties of estimators and test statistics through a theorem-proof presentation, this book squarely addresses implementation to provide direct conduits between the theory and applied work.
