  • Leveraging refers to the process by which private sector capital is mobilised as a consequence of the use of public sector finance and financial instruments.

  • Between 1981 and 1983, one of us (Max) served on the faculty of Boston Univer-sity. At the time, he was conducting laboratory studies on decision biases in negotiation. Behavioral decision research did not exist as a topic of study in most management schools. The faculty at Boston University included a number of excellent colleagues, and yet they knew very little about the emerging research on judgment. This lack of awareness among management colleagues motivated Max to write this book. The goal was to make the area of judgment a more central part of the management literature.

  • Although research on limits to arbitrage is far from played out, it is fair to say that a broad consensus is emerging with respect to the key ideas and modeling ingredients. This should not be too surprising, given that the relevant tools all come from neoclassical microeconomics: arbitrageurs can be modeled as fully rational, with no need to appeal to any behavioral or psychological biases.
