Nauro Campos, Fabrizio Coricelli Trade agreements are one of the most widely used policy tools for economic integration. Over the past decades, they have evolved both in volume and in scope. Whereas the predominant focus of early trade agreements was lowering tariffs, modern trade agreements contain a range of deeper provisions which go beyond the narrow remit of traditional trade policy instruments. Such provisions apply to trade in services as well as trade in goods, and are widespread across agreements. They encompass measures ranging from recognition of professional qualifications for service providers, investment liberalisation, and intellectual property protection commitments, to policy areas such as anti-corruption, visa, and asylum. Trade agreements which include these provision types are referred to as deep trade agreements (DTAs).
