The aim of this paper is to estimate and to compare sustainable development processes in Lithuania, Latvia and Estonia focusing on institutional dimension of sustainable development. Attention has been focused on the selection of system of indicators with particular emphasis on institutional indicators. The authors employ the most popular two multicriteria methods: Simple Additive Weighting (SAW) and multi-criteria complex proportional method (MCP). Data embracing 2004-2010 year period is being analyzed. In order to obtain a multi-faceted view, several variants of sustainable development estimations of Lithuania, Latvia and Estonia are being performed. Each variant represents a different approach to development perception. The difference lies in emphasis, which is being put on the economic and institutional aspects of development. Hypothesis has been raised that the different methods employed may affect comparison results.
