Building upon the Law & Economics literature, we examine the economic value of the choice of law (“COL”) both from the perspective of the choice of an applicable substantive law to a contract and regarding the choice of jurisdiction. We show the different ways this choice represents a resourceful tool for foreign investors and for the countries hosting their investments or economic activities. As we outline in this article, the value of the COL brings significant financial benefit to both the host state and the foreign investor, even though it is not always monetarily measurable. As we show through a series of exemplary cases, fostering investments or economic activities following the COL is a powerful driver of economic development and the implementation of new technologies. In the case of Artificial Intelligence (“AI”), for instance, as the technology becomes widely spread across economic sectors, new legislation will likely become a key factor.
