Georgakopoulos, Nicholas L.2017-04-242013Nicholas L. Georgakopoulos, The Ralston-Landreth-Gustafson Harmony: A Security!, 41 Capital University Law Review 553 (2013).https://hdl.handle.net/1805/12321The legal definition of a security is incomplete but consistent with the economic function of securities transactions and the financial theory of securities valuation (the Capital Asset Pricing Model). The switch of the regulatory environment from buyer beware to seller disclose is justified because buyers lack access to information and control.
