1. Environmental averaging

   Many classical examples of models of self-organized dynamics, including the Cucker–Smale, Motsch–Tadmor, multi-species, and several others, include an alignment force that is based upon density-weighted averaging protocol. Those protocols can be viewed as special cases of “environmental averaging”. In this paper we formalize this concept and introduce a unified framework for systematic analysis of alignment models.A series of studies are presented including the mean-field limit in deterministic and stochastic settings, hydrodynamic limits in the monokinetic and Maxwellian regimes, hypocoercivity and global relaxation for dissipative kinetic models, several general alignment results based on chain connectivity and spectral gap analysis. These studies cover many of the known results and reveal new ones, which include asymptotic alignment criteria based on connectivity conditions, new estimates on the spectral gap of the alignment force that do not rely on the upper bound of the macroscopic density, uniform gain of positivity for solutions of the Fokker–Planck-alignment model based on smooth environmental averaging. As a consequence, we establish unconditional relaxation result for global solutions to the Fokker–Planck-alignment model, which presents a substantial improvement over previously known perturbative results.

2. Where Is Pollution Moving? Environmental Markets and Environmental Justice

   Do US air pollution offset markets disproportionately relocate pollution to or from low-income or minority communities? Concerns about an equal distribution of environmental quality across communities--environmental justice--have growing policy influence. We relate prices and quantities of offset transactions to the demographics of the communities surrounding polluting plants. We find little association of offset prices or offset-induced movements in pollution with the share of a community that is Black or Hispanic or with mean household income. This analysis of 12 prominent offset markets suggests that they do not substantially increase or decrease the equity of environmental outcomes.
