To cure unemployment, what kind of economic policies should be followed by

1. a- The Classics?

2. b- J. M. Keynes?

3. c- M. Friedman?

To answer this question, you should focus only to the labor markets and for each answer use necessary labor market graph. Indicate the main properties of the labor markets (i.e., what are the labor supply and demand function of?) and explain the policies by using couple of sentences only. (Do not use Phillips curve. Only consider the labor markets for each idea.)
