We conduct both an approximate Bayesian Model Averaging (BMA) and an exact Bayesian analysis to incorporate break date uncertainty of the mean growth rate into the trend-cycle decomposition of U.S. real GDP. Our results suggest a structural break in mean growth rate of U.S. real GDP in 1970s. Comparing to the models assuming fixed break date, we find higher uncertainty in the posterior density ...

This paper revisits the least squares estimator of the linear regression with a structural break. We view the model as an approximation to the true data generating process whose exact nature is unknown but perhaps changing over time either continuously or with some jumps. This view is widely held in the forecasting literature and under this view, the time series dependence property of all the o...

Estimates of the demand for money provide important foundations for monetary policy setting but if the estimation technique does not explicitly account for structural changes then such estimates will be biased. This paper presents an investigation into the level and stability of money demand (M1) for Australia and New Zealand over the 1960-2009 period and demonstrates that both countries experi...

This paper contributes to the econometric literature on structural breaks by proposing a test for parameter stability in VAR models at a particular frequency ω, where ω ∈ [0, π]. When a dynamic model is affected by a structural break, the new tests allow for detecting which frequencies of the data are responsible for parameter instability. If the model is locally stable at the frequencies of in...

This paper attempts to take a meticulous look on stability of money demand in India Using annual data for period 1953-2007 and the Hansen (1992) and Gregory Hansen (1996) co-integration approaches with structural break. Results of the Gregory Hansen (1996) cointegration analysis show the presence of cointegration in demand for money, real GDP and nominal interest rate with structural break at 1...

introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

This paper develops a method for testing for the presence of a single structural break in dynamic panel data models with a multi-factor error structure. The test statistic is developed by combining a modified version of the GMM approach of Robertson and Sarafidis (2015) with the testing procedure of De Wachter and Tzavalis (2012). We focus on the case where N is large and T fixed. The asymptoti...
