Markov Chain Analysis for Structural Behaviour and Stability // Analyses the stability and structural behaviour of export and import patterns across multiple countries using a Markov chain modelling framework. Constructs transition probability matrices to quantify changes in trade shares between successive periods, thereby capturing persistence, structural shifts, and inter- country interdependence in trade performance. By iteratively generating expected trade distributions over time, the approach facilitates assessment of stability, long-run equilibrium tendencies, and comparative dynamics in longitudinal trade data, providing a rigorous tool for empirical analysis of exportimport behaviour. Methodological foundations follow standard Markov chain theory as described in Gagniuc (2017) Doi:10.1002/9781119387596.
