Shrnutí	Common-pool resource (CPR) analysis is a framework for diagnosing why shared natural and man-made resources are prone to overuse and for identifying the institutional conditions under which user communities can govern them sustainably without privatization or top-down state control. A common-pool resource is rivalrous (one user's consumption subtracts from what is available to others) yet costly to exclude users from. Garrett Hardin's 1968 'tragedy of the commons' framed the pessimistic baseline in which rational appropriators collectively destroy the resource, while Elinor Ostrom's 1990 Governing the Commons established, through extensive empirical work, eight design principles that distinguish durable self-governing commons from those that collapse.	The median voter model is a foundational result of political economy stating that, under majority rule with voters whose preferences are single-peaked on a single policy dimension, the ideal point of the median voter is the Condorcet winner — it cannot be beaten by any other alternative in pairwise majority voting. Duncan Black established the theorem formally in 1948, and Anthony Downs extended it in 1957 into a theory of party competition in which two vote-maximizing parties converge to the median voter's preferred policy. The model is the workhorse linking the distribution of citizen preferences to equilibrium policy outcomes in democracies.
