About the Authors
  • Many economic theories depend on the presence or absence of a unit root for their validity, and econometric and statistical theory undergo considerable changes when unit roots are present. Thus, knowledge on unit roots has become so important, necessitating an extensive, compact, and nontechnical book on this subject. This book is rested on this motivation and introduces the literature on unit roots in a comprehensive manner to both empirical and theoretical researchers in economics and other areas. By providing a clear, complete, and critical discussion of unit root literature, In Choi covers a wide range of topics, including uniform confidence interval construction, unit root tests allowing structural breaks, mildly explosive processes, exuberance testing, fractionally integrated processes, seasonal unit roots and panel unit root testing. Extensive, up to date, and readily accessible, this book is a comprehensive reference source on unit roots for both students and applied workers.

    • Introduces the literature on unit roots in a comprehensive manner
    • Can be taught in graduate-level courses on time series along with conventional textbooks
    • The most extensive, up to date and compact among the books that have been written about unit roots so far

    'Choi's monograph provides an authoritative introduction to and survey of the literature on unit roots, which spans economics, statistics and other fields. Its handbook style and clear treatment make it an extremely convenient graduate-level reference for those working with highly persistent time series data.' J. Isaac Miller, University of Missouri

    'Unit roots have been an important and prolific topic of research since the late 1970s. This book presents a comprehensive, well written, and up-to-date overview on the challenging and wide-ranging topic of unit roots. It constitutes a major contribution that will be useful and of interest to both researchers and graduate students.' Paulo M. M. Rodrigues, Nova School of Business and Economics, UNL, Portugal

    'This book gives a very comprehensive and up-to-date survey of the literature on unit roots that has developed in the past decades. It should be an invaluable text and reference for graduate students and applied researchers for many years to come.' Yoon-Jae Whang, Seoul National University
