The study looked at laws in France, Germany, India, the UK, and the US from 1970 to 2005 to see if they were becoming more similar or different in terms of protecting shareholders, creditors, and workers. They found that laws about protecting shareholders have become more similar, while laws about protecting workers have become more different. Laws about protecting creditors have both become more similar and more different. Interestingly, these trends didn't always follow the distinction between Common Law and Civil Law countries, as countries from different legal families sometimes became more similar while countries from the same legal family became more different.
