Abstract
The purpose of the study is to compare gross value added (GVA) multiplier effects across economic activities in Germany, Poland and Slovakia and to identify common sectoral regularities and country-specific differences in their composition. Using OECD national input-output tables for 2012 and 2022, the standard Miller–Blair GVA multiplier is decomposed into direct and residual effects. The results show that total multiplier values are relatively similar across the three economies, whereas their composition differs much more clearly. Education, computer programming, health and public administration consistently record some of the highest multipliers and high direct value-added intensity. Motor vehicles and electronics show a contrasting pattern: Poland and especially Slovakia combine lower direct GVA coefficients with higher residual shares than Germany. These manufacturing differences are visible in both observed years. Compared with previously estimated output multipliers, the findings show that stronger gross-production propagation does not necessarily imply a stronger value-added effect, which is relevant for sectoral and industrial-policy assessment.
