Structural Breaks and Unit Root Tests for Short Panels
نویسنده
چکیده
In this paper we suggest panel data unit root tests which allow for a potential structural break in the individual e¤ects and/or the trends of each series of the panel, assuming that the time-dimension of the panel, T , is ...xed. The proposed test statistics consider for the case that the break point is known and for the case that it is unknown. Monte Carlo evidence suggests that they have size which is very close to the nominal ...ve percent level and power which is analogues to that of Harris and Tzavalis (1999) test statistics, which do not allow for a structural break. JEL classi...cation : C22, C23

Generalized fixed-T panel unit root tests allowing for structural breaks
In this paper we suggest panel data unit root tests which allow for a structural breaks in the individual effects or linear trends of panel data models. This is done under the assumption that the disturbance terms of the panel are heterogenous and serially correlated. The limiting distributions of the suggested test statistics are derived under the assumption that the time-dimension of the pane...
متن کاملGeneral Diagnostic Tests for Cross Section Dependence in Panels
General Diagnostic Tests for Cross Section Dependence in Panels This paper proposes simple tests of error cross section dependence which are applicable to a variety of panel data models, including stationary and unit root dynamic heterogeneous panels with short T and large N. The proposed tests are based on average of pair-wise correlation coefficients of the OLS residuals from the individual r...
متن کاملStructural Breaks and Time-varying Parameter: A Survey with Application Communications of the IBIMA
The theme of instability or breaks in macroeconomic series has attracted considerable attention over the last several decades. There are a large number of tests for structural changes or the stability of parameters. We focus the review of unit-root tests, unit-root tests including possible structural breaks, and time-varying parameter literature. Unit-root tests, which concentrate on the studyi...
متن کاملThe Random-Walk Hypothesis on the Indian Stock Market
This study tests the random walk hypothesis for the Indian stock market. Using 19 years of monthly data on six indices from the National Stock Exchange (NSE) and the Bombay Stock Exchange (BSE), this study applies three different unit root tests with two structural breaks to analyse the random walk hypothesis. We find that unit root tests that allow for two structural breaks alone are not able ...
