Key Figures

Institutional International Law era

Wesley Newcomb Hohfeld [1] was a key figure in this era, with institutional ties such as Yale University [3]. His 1913 Some Fundamental Legal Conceptions as Applied in Judicial Reasoning [6] offered a rigorous account of fundamental legal conceptions and reshaped judicial reasoning, underscoring why these contributions were important for the era's interpretive jurisprudence. Frederic William Maitland [2] is associated with institutions such as Royal College of Music [4] and Universidad de Londres [5] in this period. His The History of English Law before the Time of Edward I [7] provided a comprehensive historical account that underpinned later doctrinal frameworks and comparative understandings central to institutional legal thought.

Legal Social Science and Economics era

Michael C. Jensen[1] is a leading figure in the law-and-economics era, with affiliations at Harvard University[3] and Johns Hopkins University[4]. His key contribution in this era comes from the 1983 paper Separation of Ownership and Control[7], which articulates the agency problem arising from the separation of ownership and control and shows why governance structures matter for incentives and regulatory design. Eugene F. Fama[2] is another central figure of this era, with affiliations at Cornell University[5] and University of Chicago[6]. The 1983 paper Separation of Ownership and Control[7] helped crystallize agency theory within financial economics, highlighting the effects of ownership concentration on governance and incentives and serving as a foundational insight for empirical law-and-economics and comparative institutional analysis in this period.

Legitimacy-Centered Global Law era

Andrei Shleifer [1], a prominent economist whose work in this era intersects Harvard University [3] and the Massachusetts Institute of Technology [4], helped shape the legal-finance scholarship focusing on legitimacy. His key contributions in this era come from Law and Finance [6], The Economic Consequences of Legal Origins [7], and What Works in Securities Laws? [8], which reveal how legal origins and securities regulation influence economic outcomes and underpin legitimacy-based governance rather than deterrence in global finance. Florencio López-de-Silanes [2] is a senior economist whose work during this period spans Harvard University [3] and Yale University [5]. Together with Shleifer, López-de-Silanes contributed to the same trio of papers Law and Finance [6], The Economic Consequences of Legal Origins [7], and What Works in Securities Laws? [8], advancing a legitimacy-centered account of how formal rules and institutions cultivate compliance and credibility in domestic and global markets.
