Anything that can be learned from direct experience can also be learned by indirect or vicarious experience

There will be a brief review of chapters 7 ñ 11 at the end of this lecture. There will be no lecture on Tuesday, November 13, 2001 (Reading Days)

Theorem 3.7. (Elementary Transformations). The following opera- tions applied to a linear system yield an equivalent system: ()Interchange: The order of two equations can be changed. (2)Scaling: Multiplying an equation by a nonzero constant. (3)Replacement: An equation can be replaced by the sum of itself and a nonzero multiple of any other equation

Goal Concept: A concept definition describing the concept to be learned. (It is assumed that this concept definition fails to satisfy the Operationality Criterion. Training Example: An example of the goal concept Domain Theory: A set of rules and facts to be used in explaining how the training example is an example of the goal concept

Ancient Greek philosophy was divided into three sciences: physics, ethics, and logic. This division is perfectly suitable to the nature of the thing; and the only improvement that can be made in it is to add the principle on which it is based, so that we may both satisfy ourselves of its completeness, and also be able to determine

The Multiplier Process as Market Exchange Process A Contribution to the Micro Foundation of Keynesian Macroeconomics Abstract Traditional equilibrium analysis has been incorrectly founded once an \ordering issue\ is concerned. To circumvent this problem, the autonomous demand, which has been missed in traditional microeconomic analysis, has to be introduced into the system as a starting point of a sequence of market exchanges. Following this direction, Keynes's multiplier analysis can also be viewed as a description of the process through which market exchanges are generated. Further

I guess I have to come out to reply to those who concern with the nature rate of unemployment. First, What is the natural rate of unemployment? It is assumed to be the unemployment rate at the steady state or equilibrium. Note that equilibrium here is not referred to the common demand-supply equilibrium, but to a state at which things are not changed, or remain the same. More specifically, suppose we can have an economy that could be expressed by the following dynamic system
