“…Regarding testing for change points, several test statistics have been proposed by Emerson and Kao (2001, 2002), de Wachter and Tzavalis (2012), and Horváth and Hušková (2012), among others. Regarding estimation of multiple change points, one part of the literature is concerned with heterogeneous panels where the slope parameters are allowed to change across individuals or other panel units (see, e.g., Bai, 2010; Baltagi, Feng, & Kao, 2016; Chan, Horváth, & Hušková, 2013; Cho & Fryzlewicz, 2015; Cho, 2016; Horváth & Hušková, 2012; Kim, 2011; Okuy & Wang, 2018; Torgovitski, 2015). The other part, including this paper, focuses on homogeneous panels, where the slope parameters are constant across individuals.…”
