This led to many questions about the value and the enforceability of insider trading laws.
Later, in "The World Price of Insider Trading" he discovered the fact that insider trading laws in themselves are not effective - they only start being effective once there is credible enforcement.

He has taught at top universities in Argentina, Brazil, China, France, Germany, Holland, India, Indonesia, Italy, Japan, Mexico, New Zealand, Portugal, Singapore, Slovenia, South Korea, Russia, Taiwan, Turkey and the USA (Duke University, MIT and University of Chicago Booth School of Business).
