Brattle economists are frequently involved in matters pertaining to the management of solid and toxic wastes. We work with federal, state, and municipal government entities to address waste management problems and advise on regulations for the disposal of hazardous and non-hazardous materials. Our economists have been at the center of the debate regarding the constitutionality of flow control ordinances enacted by city and county governments, and played a role in the key legal decisions regarding the Commerce Clause, including the Pike balancing test and the interstate nature of waste collection and disposal markets.
