Dissertation Title:  ‘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.

Dissertation Committee

Prof. Michael S. Knoll (Penn Law/The Wharton School); Prof. Daniel M. G. Raff (The Wharton School), another to be appointed.
