This classroom exercise illustrates the Tiebout (1956) hypothesis that residential
sorting across multiple political jurisdictions leads to a more efficient allocation
of local public goods. The exercise places students with heterogeneous preferences
over a public good into a single classroom community. A simple voting mechanism
determines the level of public good provision in the community. Next the classroom
divides in two, and students may choose to move between the two smaller communities,
sorting themselves according to their preferences for public goods. The exercise
places a cost on movement at first, then allows for costless sorting. Students
have the opportunity to observe how social welfare rises through successive
rounds of the exercise, as sorting becomes more complete. One may also observe
how immobile individuals can become worse off due to incomplete sorting when
the Tiebout assumptions do not hold perfectly.
