Agglomerama--Fennell on Cities' Participant Assembly Problem

Lee Fennell (Chicago) has posted Agglomerama, __ BYU L. Rev __ (forthcoming).  In it, she examines how cities attract the right mix of residents and businesses to maximize social value.  She takes a look at a number of possible ways in which cities might incentivize and manage positive spillover effects, including a proposal by Gideon Parchomovsky and Peter Sieglman to emulate shopping mall developer coordination between anchor and satellite tenants, which proposal can be found in their Cities, Property and Positive Externalities, 54 Wm.  & Mary L.Rev. 211 (2012).  Here's the abstract for the Fennell piece:

Urbanization presents students of commons dilemmas with a pressing challenge: how to achieve the benefits of proximity among people and land uses while curbing the negative effects of that same proximity. This piece, written for the 2014 BYU Law Review Symposium on the Global Commons, focuses on the role of location decisions. It casts urban interaction space as a commons that presents the threat of overgrazing but that also poses the risk of undercultivation if it fails to attract the right mix of economic actors. Because heterogeneous households and firms asymmetrically generate and absorb agglomeration benefits and congestion costs, cities embed an interesting collective action problem — that of assembling complementary firms and households into groupings that will maximize social value. After examining the nature of this participant assembly problem, I consider a range of approaches to resolving it, from minor modifications of existing approaches to larger revisions of property rights.
