Waleed Y. W. Haj Hasan

Waleed is, currently, an Associate Attorney (Corporate) at Cravath, Swaine & Moore LLP. He is, simultaneously, pursuing his doctorate in an Economic Analysis of Monetary Law and Policy at the University of Pennsylvania Carey Law School. Waleed is an Attorney and Counselor-at-Law in the State of NY and earned his LL.M., with the Wharton Business and Law Certificate, from the University of Pennsylvania (2020) and his LL.B. (Hons.) from the University of Edinburgh (2019). Waleed held several Teaching Assistant positions at both the Law School and The Wharton School. During his doctorate, Waleed interned with the U.S. Commodity Futures Trading Commission (U.S. CFTC) for six months; having, previously, externed at the New Jersey Office of the Attorney General and completed internships at Baker Botts LL.P. (London, UK), Hadef & Partners (Dubai, UAE), and Dentons (Amman, Jordan).


The title of Waleed’s project is: ‘Of interest: a treatise on the legal conception of the time value of money’. It will start with an assessment of the historical evolution of the values, attitudes, and beliefs underpinning the philosophical and legal treatment of, and thought around, interest (‘carentia pecuniae’). Waleed will, then, explore the private law, central banking, and tax treatment of interest; from which he will inductively infer, from the first principles, a legal conception of interest. He will conclude the project, drawing on all preceding work and a normative economic framework, by offering a discussion on reform.
