In case the underlying game is a unanimity game, we show that each of these values can be computed using the inclusion-exclusion principle. Linearity of both values permits us to calculate them without needing the dividends of the induced games (graph-restricted game and link game). The expression of these dividends is only derived in the existing literature for special communication situations. Moreover, the associated inclusion-exclusion decomposability property depends on what we have called the graph allocation rule. This rule is the relative degree (relative indicator) for the position value (Myerson value).engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1573-7187http://doi.org/10.1007/s11238-004-5636-4https://link.springer.com/article/10.1007/s11238-004-5636-4restricted access519.813519.8Allocation rulesInclusion-exclusion decomposability propertyMyerson valuePosition valueTeoría de JuegosInvestigación operativa (Estadística)1207 Investigación Operativa1207.06 Teoría de Juegos
