A small forward-looking inter-country model (Belarus, Russia and Ukraine)

The paper describes an inter-country model developed on the New Keynesian Phillips curve principle for the economies of Belarus, Russia and Ukraine. Technically the modelling idea has been grounded within the concept of the infinite dimensional vector autoregressive models by Chudik and Pesaran [Chudik A., Pesara M.H., 2007. Infinite-dimensional VAR's and factor models. IZA; DP No. 3206]. The main developments are such that the model is 1) interdependent rather than vector autoregressive, 2) estimated by the generalised method of moments and 3) forward-looking. The primary linkage of the country models is provided through the real effective exchange rates of particular countries, while the secondary linkages are through the Chudik and Pesaran cross-sectional augmentations. A series of Monte Carlo experiments confirms that the small cross-dimension of the model and a possible dominance of one country in the panel (Russia) should not distort the results in a significant way. A series of stochastic simulation experiments made with and without the assumption of observational equivalence principle shows a possible spread of the Dutch Disease from Russia to other countries in the model.
