Testing the efficacy of the economic policy uncertainty index on tourism demand in USMCA: Theory and evidence (2020, methodology): “Hence, in this time series model, we apply Lee and Strazicich’s (2003) unit root test among many other alternative and interacting tests following each other (Lee et al., 2012; Meng et al., 2017; Narayan and Popp, 2010; Zivot and Andrews, 1992).”
Examining the determinants of inward FDI: Evidence from Norway (2015, background): “The study employed structural breaks that are exogenous and it is argued that this may lead to false acceptance of the unit root null hypothesis (see Lumsdaine and Papell 1997; Narayan and Popp, 2010; 2013 for review).”
Does urbanization cause increasing energy demand in Pakistan? Empirical evidence from STIRPAT model (2017, methodology): “The Narayan and Popp (NP afterwards)[51] unit root test is superior to other unit root tests such as: (i) there is no need to have information about the possible timing of structural break stemming in the series because NP test determines the break dates endogenously within model.”
Modeling returns and volatility transmission between oil price and US–Nigeria exchange rate (2013, background): “4 Narayan and Popp (2010) provide computational advantages of the sequential approach over the simultaneous approach of identifying optimal break point dates.”
Hourly Oil Price Volatility: The Role of COVID-19 (2020, unknown): “In unreported results, we also performed the Narayan and Popp (2010, 2013) structural break unit root test and found all variables to be stationary.”
Exploring the nexus of electricity consumption, economic growth, energy prices and technology innovation in Malaysia (2013, methodology): “The critical values for one and two breaks are obtained from Zivot and Andrews [8] and Narayan and Popp [9], respectively.”
Nonlinear causality between crude oil price and exchange rate: A comparative study of China and India - A Reassessment (2019, methodology): “Finally, BR (2015) decision for considering real oil price series as I(1) at level was based on the results derived from Narayan and Popp (2010) unit root test with two structural breaks at level and slope (see, BR, 2015, Table 2, pp.153).”
An (a)symmetric analysis of the pollution haven hypothesis in the context of Pakistan: a non-linear approach (2019, background): “Hence, the structural break proposed by Narayan and Popp [54] was performed with two breaks in the slope and level, the timing of which is supposed to be unknown.”
