Research Project

"Culture, Law, and the Economy:
Explaining Diversity in Business Regulations and Perspectives for their Coexistence"

Mainstream economic theory suggests there should be only one method of regulating the economy. This, however, contrasts with the various models one can observe functioning across the globe. This project seeks to attribute this diversity to differences in culture as expressed through legal institutions, i.e. legal rules, concepts, and practices. By using examples from several jurisdictions, it will show that legal institutions existing in major capitalist economies are based on diverging assumptions, customs, and habits. It will also demonstrate how these legal institutions react upon the culture of the countries adopting them, giving each legal system its distinct ‘flavor’.

Diverging cultures and regulations across states have ramifications for the governance of the global economy. Differing attitudes clash when it comes to the worldwide regulation of areas which are of fundamental importance to mankind, such as trade, finance, intellectual property, human rights, and environmental protection. This project will analyze this process and the obstacles that cultural divergence poses to legal harmonization, cooperation, and coordination. It will also explore whether and how different cultures have merged into one global business law culture, and, if so, identify the traits characteristic of this global culture and the areas in which key differences remain as well as offer  reasons for these developments.
