Abstract
Contemporary literature of international economic law (IEL) is considerably influenced by the rational choice paradigm and various economic theories based on this model. This may be explained primarily by the paramount role of the rational-choice model in mainstream international economic theory, which is conventionally considered by many experts the natural habitat of IEL. Consequently, IEL scholars and readers are often predisposed to perceive the abundant new information in this sphere (such as new treaty provisions or judicial decisions) through an economic lens. Sociological analysis may recast well-known dilemmas differently and generate insights regarding better legal mechanisms for coping with the modern challenges faced by IEL. These properties of sociological analysis are illustrated in this paper that addresses two challenging dilemmas in current IEL literature: the relationship between the World Trade Organization (WTO) and regional trade agreements (RTAs), and the interactions between international investment law and other branches of international law (prominently international human rights law).
