We propose moving average threshold heterogeneous autoregressive (MAT-HAR) models as a novel combination of heterogeneous autoregression (HAR) and threshold autoregression (TAR). The MAT-HAR has multiple groups of lags of a target series, and a threshold term can appear in each group. The...

This paper empirically analyses the long-run relationship among the variables in the aggregate import demand functions of Madagascar and Mauritius in order to evaluate the appropriateness and effectiveness of the structural adjustment programmes (SAPs). Given the small sample size, we use the...

The existing vector heterogeneous autoregression (VHAR) does not allow for threshold effects. The threshold autoregressions are well established in the literature, but the presence of an unknown threshold complicates inference. To resolve this dilemma, we propose the vector moving average...
