Résumé :

Background: The unit root became the most important feature that directed to the construction of new time series econometrics. Objectives: The study of time series structural breaks was a specific area of unit root research. Methods: Conventional procedures assume the break and apply a test accordingly. This leads to identification of spurious breaks, and therefore biased results, Lee and Strazicich, (2001). Results: We suggust an alternative strategy where we propose to test for structural breaks before applying unit root test. The debates of Structural breaks in unit root testing starts with

Résumé :

Time series analysis is based on the assumption of stationarity. Stationarity implies the parameters are constant over time. Structural break occurs when at least one of the parameters changes at some date. Structural breaks can lead to huge forecasting errors and unreliability of the model. Modelling structure breaks is very popular in the literature of macroeconomics and finance. However, there are still too few publications about structural breaks in agricultural market. The goal of research is to identify structural breaks in wheat prices time series. A few structural break tests are appli

Résumé :

The study investigates the impact of structural breaks on the long memory of daily returns and variance of 11 sectors. Using multiple sequential structural breaks tests, we uncover numerous and roughly shared structural breaks. Results from two non-parametric, three semi-parametric, and three parametric fractional differencing models using break-adjusted and break-unadjusted returns reveal incidence of short memory and anti-persistence in sector returns. Regarding variance, we find that the removal of breaks from the sector series dampens the fractional differencing parameter estimates. Theref

Résumé :

This study revisited the tourism-led growth hypothesis (TLGH) in the presence of structural breaks using the structural break technique of Ditzen et al. (2021). To estimate the impact of tourism on economic growth along the identified structural breaks, we employed Fixed Effects and Feasible Generalised Least Squares methods. Findings showed four structural break dates (1999, 2004, 2009 and 2014), two of which coincided with the Global Financial Crisis (2008-2009) and the Ebola outbreak (2014). Despite the presence of structural breaks, the TLGH remains valid.

Résumé :

To search for eras in a sports league, we utilize time-series tests with structural breaks in Major League Baseball performance. Using data from 1871-2010, the mean and standard deviation of four different performance measures are examined. Throughout, rather than assume that a break point is known a priori, we identify breaks endogenously from the data. Perhaps most notable among our findings, we identify a deterministic trend in mean slugging percentage with breaks in 1921 and 1992. Interestingly, these years closely coincide with the early years of the free-swinging (Babe Ruth) era and the

Résumé :

Abstract Estimation of models with structural breaks usually assumes a pre-specified number of breaks. Previous models which do allow an endogenously determined number of breaks require a simple structural model, and rarely allow for information transfer across the break. We introduce a methodology that allows the number of breaks to be determined endogenously and including an economically motivated model of transition regimes between each break. We demonstrate the usefulness of our approach for forecasts of the equity premium. We find the demonstrated success of the historical average can be

Prior to 2005, five or six factors are selected, but just two are selected thereafter. This finding offers a simple implication for the factor zoo literature: ignoring breaks detects additional factors that are no longer relevant. Moreover, all omitted factors are priced by the selected factors in every regime. Finally, the s

Résumé :

A number of studies have already determined the existence of inverted U-shaped environmental Kuznets curve in Pakistan however the role of structural breaks in determining the relationship is yet to be investigated. The objective of this study was to determine if the presence of possible structural breaks explain the existence of environmental Kuznets curve type relationship in Pakistan for the period 1980-2016 by using data of total energy consumption, Real GDP per capita, foreign direct investment and trade openness. For the analysis the study first used the conventional time series economet

Résumé :

Abstract We investigate several promising algorithms, proposed in literature, devised to detect sudden changes (structural breaks) in the volatility of financial time series. Comparative study of three techniques: ICSS, NPCPM and Cheng’s algorithm is carried out via numerical simulation in the case of simulated T-GARCH models and two real series, namely German and US stock indices. Simulations show that the NPCPM algorithm is superior to ICSS because is not over-sensitive either to heavy tails of market returns or to their serial dependence. Some signals generated by ICSS are falsely classifie

Résumé :

Abstract In this paper, we utilize time series tests with structural breaks to test for evidence of an impact on economic growth rates in North African countries following the 2007−2009 U.S. and global financial crisis. One or two breaks in economic growth are identified in each country, except for Morocco where no break is found. However, breaks that coincide with the financial crisis are found in only two of the six countries (Libya and Mauritania), while other breaks coincide most often with earlier U.S. and EU recessions. To further examine the impact of shocks, impulse response functions

Résumé :

The objective of this study is to execute a comprehensive analysis of the unit root test and structural break in Malaysia unanticipated macroeconomic variables from January 2009 to December 2016 using an endogenous structural break. The findings obtained by using conventional regression methods without testing for the unit root in time series data might be misleading. The empirical results from the Zivot-Andrews model, which endogenously identifies the most significant structural breaks in each of the macroeconomic variables, clearly show that the null hypothesis of at least one-unit root coul

Résumé :

This study examines the impact of structural breaks on the relationship between natural gas production and economic growth in Nigeria, with a focus on the 2010 policy reforms. Utilizing the Autoregressive Distributed Lag (ARDL) model, the analysis incorporates structural breaks to assess their influence on the natural gaseconomic growth nexus. Two models were estimated: One model assumed a single structural break in 2010, and the other introduced dummy variables to isolate the effects of structural changes. The findings indicate that the model that explicitly accounts for structural shifts usi

Résumé :

This study investigates the effects of structural breaks on the Colombo Stock Exchange (CSE) performance over the COVID-19 period. Stock market returns and volatility are used to proxy the stock market performance. Structural breaks were identified by using the Bai-Perron (2003) test. An ARMA (p,q) model fitted for stock returns was augmented using dummy variables for the structural breaks to measure the effect of structural breaks on stock market returns. The model was further extended as a volatility regression model (GARCH, EGARCH, or TGARCH) to measure the effect of structural breaks on st
