Ringkasan	Two-level game analysis is a framework introduced by Robert Putnam in 1988 for understanding how international negotiations are jointly shaped by bargaining between governments and the need to win domestic approval. A negotiator plays simultaneously at two tables: Level I, where states bargain over an agreement, and Level II, where that agreement must be ratified by domestic constituents. The key analytic device is the win-set — the set of Level I deals that could secure domestic ratification — and an agreement is possible only where the negotiating states' win-sets overlap.	The Shapley Value is a solution concept for coalition games that distributes total payoff fairly among players based on their marginal contributions to coalitions. Introduced by Lloyd Shapley in 1953, the Shapley Value is the unique payoff distribution that satisfies four intuitive axioms: efficiency (total payoff is distributed), symmetry (identical players receive equal payoff), null player (players contributing nothing receive nothing), and additivity across games.
