A first reaction to these developments might be that they are favorable, as alongstanding tenet of state and local public finance has been that on efficiency grounds it ispreferable to assess subnational taxes using jurisdictions that encompass greater areas andlarger populations (e.g., state rather than local), as the interjurisdictional mobility of taxbases is significantly lower for such jurisdictions than for smaller entities; as a result,efficiency costs from suboptimal location decisions will be reduced, more progressivity in thetax structure may be introduced if deemed desirable, and economies of scale in revenuecollection may be realized.
