That is, to implement the right business must not only take into account the right but also the economy. In this sense we can say that the economy is the science that deals with using resources in a context of scarce resources, and there is also the economic analysis of law that seeks the economic efficiency of legal institutions (we do not mean the same for us have dealt with it in another venue, the work to be consulted to take a comprehensive approach to research topic). However, it is clear that few lawyers have studied economics and few lawyers dominate the economic analysis of law. Therefore it is an advantage that can be used by lawyers who just started their studies or recent graduates. It is very common to find lawyers theorists, but rare lawyers who dominate the theory and practice which results in that many are theoretical and studies are theoretical.
Therefore we must abandon theoretical studies not understand all the subject matter of study in a comprehensive manner. However, we should point out that the theory is also very important in the study of law. That is, the theory and practice complement to be two issues of vital importance in the study of business law. Therefore we can say that we should not ignore either the theory or practice in the study of business law. But it is clear that the theoretical and academic known for having that status which are usually professors or write articles, manuals and treaties, which are renewing teaching approaches, which also is the source and part of the law.
