  The following measures against unemployment are proposed: In the short term,
to promote greater income for the poorest sectors. It is shown that this can be
paid with the resulting increased production, without losing income to the
other economic agents. In the mid term, the creation of ad-hoc companies for
investment in projects profitable but long lasting. And in the long run, the
abandonment of the competitive models. As these proposals go against current
ideas (liberalisation, labour market flexibility, free market, etc.), the
statements are rigorously demonstrated, even at the risk of making the lecture
harder.
  Part 1 explores the problem and uses a simple model and others heuristic
arguments to create familiarity with macroeconomic models. Part 2 is a
simplified summary of Macroeconomic Theory textbook. It serves as a review to
the reader whose knowledge in economy are out of date, or as a first
approximation to the topic if he or she does not have them. In the light of the
theory, economic policies are evaluated for the Argentine case in the 90's. The
work accepts the Keynesian explanation of unemployment (insufficient demand),
but we disagree on its solution (public expenditure). Finally, in Part 3 we
elaborate and justify the proposals.
