This paper proposes asymptotically optimal tests for unstable parameter process under the feasible circumstance that the researcher has little information about the unstable parameter process and the error distribution, and suggests conditions under which the knowledge of those processes does...

In this paper we examine several approaches to detecting changes in the adjustment coefficients in cointegrated VARs. We adopt recursive and rolling techniques as mis-specification tests for the detection of non-constancy and the estimation of the breakpoints. We find that inspection of the...

This paper considers savings, investment and economic growth for India using annual time series data for the period 1950/51 to 2003/04. The analysis uses Perron’s innovational outlier model to conduct unit root tests which endogenously determines a structural break. The empirical results show...

A recent outbreak of bird flu or avian influenza (AI), an especially highly pathogenicstrain (HPAI) of H5N1, started in Hong Kong in January 2003 and caused 159 humandeaths in Asia, Africa and Europe through early 2007. In addition, this outbreak resultedin millions of slaughtered birds and...

The unusual rise and fall of non-monetary trade (NMT) in the Russian transition has been a subject of heated debates. Yet, this phenomenon is often viewed as a peculiarity that one cannot explain by economic considerations alone. In this paper we show that the resort to NMT was a rational,...

In the doctoral dissertation, we consider problems of testing and estimating changed segment with unknown starting position and duration of epidemic state in the autoregressive first-order model. The proposed tests are based on partial sums of model residuals and model-parameter...
