Foundations of Public Contracts undertakes an in-depth survey of the foundations of public contracts in three legal systems: American, French, and Brazilian. The comparison of these three systems highlights the legal phenomenon's historical, philosophical, and social origins. The book transcends the functional commonalities to penetrate into how American, French, and Brazilian lawyers think about the essence of government contracts law, the phenomenon of exceptionalism: preferential treatment that public procurement law provides to the state in its contractual dealing with private entities. Comparative public law professors and students will find great value in this exploration of the material sources of public contracts, an area that has heretofore received little attention in legal academia.
