Summary: Textbook for course: http://www.hup.harvard.edu/catalog/MYEGAM.html " Decision theory is a body of knowledge and related analytical techniques of different degrees of formality designed to help a decision maker choose among a set of alternatives in light of their possible consequences. Decision theory can apply to conditions of certainty, risk, or uncertainty. [decision UNDER certainty] means that each alternative leads to one and only one consequence, and a choice among alternatives is equivalent to a choice among consequences." http://pespmc1.vub.ac.be/ASC/DECISI_THEOR.html Eric Lindblom
