Trade in services is a complex topic in global trade. Different rules and agreements govern how services are traded between countries. Fragmentation in these rules can lead to better policies and innovations. By introducing a necessity test and more transparency, the quality of services trade regulation can be improved. The current rules on migration in services trade favor high-skilled workers over low-skilled ones, creating a divide. When deciding if services are similar, the competitive relationship between suppliers and services in the market must be considered.
